The study finds that knowledge culture strongly influences the climate component of learning culture (H3b), and this relationship applies to all four industries. In contrast, the mistakes acceptance component of learning culture is strongly supported by knowledge culture in the construction and HE industries (H3a). For the healthcare industry, this relationship is weaker but still significant, and it is insignificant for the IT industry. Thus, the mistakes acceptance component of learning culture is not equally observed in all four industries, meaning that the potential of mistakes as a source of learning is not likely to be equally used in industries as a potential source of tacit knowledge awareness.Moreover, the results demonstrate that knowledge culture strongly supports formal knowledge processes (H4a) and significantly and strongly supports informal tacit knowledge processes for the healthcare industry (H4b). For the IT industry, this relationship is weaker, and it is not significant for the construction and HE industries. In addition, it was discovered that learning culture is more important than knowledge culture for informal tacit knowledge sharing (H4c-d). The climate component of learning culture is found to have a significant and direct effect on tacit knowledge sharing in the construction, HE and IT industries (H4c). This effect is not significant in the healthcare industry. In contrast, the climate component of learning culture supports the mistakes acceptance component of learning culture in the


Introduction
Intellectual capital (IC) is a central focus of knowledge-driven companies today. It is believed there is no knowledge without IC and vice versa (Rastogi, 2000). Therefore, studies exploring this bidirectional relationship (Garcia-Perez et al., 2020) are vital for organizational development because they strive to understand this relationship and they help organizations shape their policies in favor of creating both knowledge and IC.
This study focuses on IC creation arising from knowledge processes and contributes to the literature by demonstrating how tacit and explicit knowledge affect IC. This exploration is needed to understand the contradiction identified by Mabey and Zhao (2017), who revealed that "the more knowledge is formally managed, the less likely effective knowledge exchange will occur" (p. 43); they named this phenomenon the "knowledge paradox." Solving the mechanism of this paradox is vital for knowledge management theory and practice; however, following Rastogi (2000) and Garcia-Perez et al. (2020), this only seems possible through a more in-depth investigation of ICrelated and knowledge management-related organizational processes. This exploration is needed because tacit and explicit knowledge forms are created differently across the organization, which might affect IC. Specifically, this study aims to expose how informal processes of tacit knowledge and formal processes of explicit knowledge influence each component of IC.
Both tacit and explicit knowledge are important in IC development. Moreover, while each IC component (i.e. human, relational, structural and renewal) is vital for organizational performance and development (Ahmed et al., 2019), they require different types of organizational support (Matricano et al., 2020). This study provides an in-depth exploration of how these four IC components contribute to organizational innovativeness performance. Specifically, it shows how the components are created through formal and informal knowledge processes when shaped by organizational culture and driven by transformational leadership, resulting in IC followed by innovativeness. Moreover, Watkins and Kim (2018) stated that if the assumption that organizational learning culture enhances knowledge creation and innovation is empirically confirmed, it is a highly significant discovery. Thus, the ambition to deliver this proof justifies this study's profound complexity.
Further, in a comprehensive literature review, Bellucci et al. (2021) noted the urgent need for studies conducting in-depth explorations of the interconnections between knowledge management, IC, and market performance with innovation. This study, strongly inspired by the literature presented above, directly responds to this call.
Moreover, it is argued that transformational leadership is a key factor in enhancing learning, knowledge, and innovation relations (Klaic et al., 2020). Alrowwad et al. (2020) demonstrated that transformational leadership affects innovation through IC and presented the general mechanisms of this effect. This study aims to delve deeper to reveal the micromechanisms.

Theoretical framework
All of the factors mentioned so far are related. However, the "big picture" of all IC creation micromechanisms linking transformational leadership with organizational innovativeness is still missing. Moreover, the issue of how formal and informal knowledge processes shape IC and the overall relationship between leadership and innovativeness remains unexplored. While some extant studies demonstrate a link between leadership, organizational innovativeness, and the factors of culture, IC and knowledge processes (e.g. Pellegrini et al., 2020), they explain focal parts of the relationship rather than its entire structure. This study aims to fill this gap. A deeper understanding of the essence of the aforementioned relations is important for transformational leadership and innovativeness relation exploration, which is vital for learning organizations' growth. Moreover, revealing these micromechanisms is critical for: (1) understanding how particular IC components in organizations are developed as a result of knowledge processes (Garcia-Perez et al., 2020;Matricano et al., 2020).
(3) providing empirical proof supporting the theoretical thesis that learning culture influences organizational innovativeness (Watkins and Kim, 2018).
This knowledge is desired by theory and practice to improve organizational innovativeness.

Research question
This study aims to answer the following research question: How do formal and informal knowledge processes shape IC and link the overall relationship between transformational leadership and innovativeness due to company culture?

Research problem
The research problem addressed in this study concerns transformational leadership and the innovativeness of learning organizations. All factors mentioned in the Introduction section are related, but the details are not known. This lack of knowledge makes it impossible to understand the micromechanisms linking transformational leadership with organizational innovativeness; this understanding is desired by theory and practice to improve organizational innovativeness.

Aim
This study aims to present an overview of IC creation micromechanisms of formal and informal knowledge processes driven by organizational culture and transformational leadership to achieve innovativeness. Specific objectives that support the general aim will: (1) clarify how the IC components are created in the organization in the relation to knowledge processes.
3. Hypotheses 3.1 Transformational leadership shapes organizational culture Transformational leaders are a prominent group because they establish organizational ideas and visions, create strong bonds with employees, motivate employees, and are supportive and inspirational (Busari et al., 2019). Such leaders are able to effect change through the development of organizational culture (Brandt et al., 2019). However, leaders sometimes focus too much on changing organizational policies rather than changing the organizational mindset, often failing to improve performance as a result (Schwartz, 2018). Thus, this study focuses on transformational leadership that actively shapes organizational culture to ensure good innovation performance of learning organizations. Learning organizations facilitate the learning process of all employees, continuously transforming themselves (Peler et al., 1989). Therefore, a desire to possess knowledge is a motivation for learning. Given that learning always changes the perception of things, leaders should support an organizational culture focused on knowledge, learning, and innovativeness at the individual and organizational levels (Watkins and Marsick, 1996), and facilitating the flow of constant transformation of tacit knowledge into explicit knowledge (Nonaka et al., 2000). Further, learning organizations are a formal management system, whereas organizational learning is an activity that occurs as a result of formal systemic enhancements and even without them (Werner, 2017).
Leadership, culture, intellectual capital Therefore, a learning culture that is understood as employees' positive attitudes and behaviors toward learning processes is vital for formal and informal organizational learning processes. Naqshbandi and Jasimuddin (2018) demonstrated that knowledge-oriented leadership affects knowledge management capability, which is broadly defined as creating infrastructure and processes to increase innovativeness. These researchers followed Donate and de Pablo (2015), who found that a knowledge-oriented company culture influences knowledge management practices, and that knowledge processes are supported by leadership. Transformational leadership supports knowledge sharing (Coun et al., 2019) and creates an organizational culture that promotes knowledge, learning, and innovativeness (Anselmann and Mulder, 2020). Therefore, the following hypotheses are proposed: H1. Transformational leadership has a positive effect on the culture of learning.
H2. Transformational leadership has a positive effect on the organizational culture of knowledge.
The spontaneous flow and exchange of tacit knowledge require strong leadership to create favorable conditions for doing so (Mabey and Nicholds, 2015). According to Mabey and Zhao (2017, p. 48), intentional leadership "based on a collaborative ethic is necessary for the creation of a 'shared' space to promote informal knowledge exchange". Leaders must facilitate such learning interactions to transform tacit knowledge into explicit knowledge. To support knowledge sharing, organizations also need to develop a culture in which employees can learn, unlearn, and relearn in a safe climate (Nold, 2012). Farnese et al. (2019) also demonstrated the importance of culture for overall organizational learning. Boh and Wong (2013) noted that organizational climate is vital for learning. Moreover, leadership positively affects the psychological safety climate of organizations, with this climate mediating the relationship between leadership and tacit knowledge sharing (Shao et al., 2017). Given that the climate component promotes learning and the mistake acceptance component forms learning culture (Kucharska and Bedford, 2020), the following hypotheses are proposed: H1a. Transformational leadership has a positive effect on the climate component of learning culture.
H1b. Transformational leadership has a positive effect on the mistake acceptance component of learning culture.
Employees with learning mindsets are open to changes and "are ready to be wrong" (Senge, 2006), meaning they accept the occurrence of mistakes and learn from them. Zappa and Robins (2016) stressed that the essence of organizational learning is to identify and modify mistakes. Thus, as demonstrated by Kucharska and Bedford (2020) and Kucharska (2021), the climate component of learning culture supports the acceptance of mistakes in the learning process. Therefore, the following hypothesis is formulated: H1c. The climate component of learning culture supports the mistake acceptance component.

Knowledge culture affects learning culture
Organizational culture facilitates the creation and distribution of knowledge (Aramburu et al., 2015). Islam et al. (2015) defined knowledge culture as one that has the conditions to support the flow of knowledge across the organization. Watkins and Marsick (1996, p. 4) noted that "a learning organization must capture, share, and use knowledge so its members can work together to change the way the organization responds to challenges. People must question the old, socially constructed, and maintained ways of thinking. Learning must take place and be supported in teams and larger groups, where individuals can mutually create new knowledge. And the process must be continuous because becoming a learning organization is a never-ending journey." In light of this, learning culture is crucial for organizations but is ineffective without the implemented culture of knowledge. P erez L opez et al. (2004) and Kucharska and Bedford (2020) argued that there is no learning culture without knowledge culture. Eid and Nuhu (2011) also noted the significant effect of knowledge culture on learning. Therefore, the following hypotheses are proposed: H3a. Knowledge culture has a positive effect on the climate component of learning culture.
H3b. Knowledge culture has a positive effect on the mistake acceptance component of learning culture.

Organizational culture shapes knowledge processes
Knowledge is the "life blood of most organizations today" (Mabey and Zhao, 2017, p. 39). Thus, the principal focus of organizations is to create and maintain conditions and processes for using knowledge and creating a competitive advantage (Leone and Schiavone, 2019). Inkpen and Tsang (2005) emphasized that access to knowledge is important but not sufficient for effective knowledge capturing and sharing. Moreover, Heisig (2009) noted that, apart from knowledge processes, technology, and entire organization design, human-oriented factors such as culture and leadership are critical to ensure the successful implementation of knowledge management that effects are visible in performance. Furthermore, an organization's knowledge culture can shape employees' positive attitudes toward (tacit and explicit) knowledge that supports the smooth flow of all knowledge processes. This assumption is justified by the fact that formal acts are caused by formal rules and policies, while informal acts are shaped by informal rules (North, 1990). Company culture accommodates both formal and informal rules. Knowledge (tacit and explicit), according to culture, is shared formally and informally. The tacit component of knowledge reflects novelty. The distinction between the explicit and tacit components of knowledge is perfectly explained by Nonaka's et al. (2000) "ba" concept, which determines the moment of transforming the uncodified, often unconscious tacit knowledge into the conscious and easily codified explicit form. The sharing of both explicit and tacit knowledge is important and expected. It can also depend on the promise of perks and other motivational benefits (Shao et al., 2017) or the overall company culture focused on a positive attitude toward knowledge and learning. The understanding and appreciation of knowledge as a resource that is visible in knowledge culture lead to knowledge management and the development of formal knowledge processes. As a result, knowledge culture supports these processes (Intezari et al., 2017). Thus, the following hypothesis is proposed: H4a. Knowledge culture has a positive effect on formal explicit knowledge processes.
In contrast to the explicit form of knowledge, which is expressed in words and data and codified into many easy-to-share forms (e.g. books, reports, documents, databases), tacit knowledge is personal, context-specific, stored in the human mind, and, undoubtedly, impossible to be formalized (Olaisen and Revang, 2018). Crane andBontis (2014, p. 1136) defined tacit knowledge as "acquired unconsciously and automatically, but capable of influencing action". Most tacit knowledge processes occur inside the human mind. Most of them are unconscious, except when they are revealed and shared e.g. when knowledge workers actively collaborate (Asher and Popper, 2019). Therefore, tacit knowledge generation and sharing are not formalized or structured but depend on the knowledge owner's free will, while the factor supporting such sharing includes personal motives (e.g. altruistic motives or Leadership, culture, intellectual capital desire for self-presentation associated with creating an impression of being an expert). Therefore, following Islam et al.'s (2015) statement that knowledge culture supports the flow of knowledge throughout the organization, it is assumed that knowledge culture might motivate knowledge workers to share their newly discovered thoughts and ideas. Thus, the following hypothesis is formulated: H4b. Knowledge culture has a positive effect on tacit knowledge sharing.
Informal sharing is greatly dependent on social skills, cohesion, and the willingness to commit time and effort to share knowledge with others (Reagans and McEvily, 2003). Shao et al. (2012) revealed that tacit knowledge-sharing behaviors are motivated by psychological reasons and facilitated by contextual factors such as organizational climate. Garvin (1993, p. 80) defined an organization with a learning culture as an "organization skilled at creating, acquiring, and transferring knowledge, and at modifying its behavior to reflect new knowledge and insights". A culture that enables a channel of knowledge flow to be created greatly supports tacit knowledge sharing (Mabey and Zhao, 2017). Therefore, the following hypotheses are proposed: H4c. The climate component of learning culture has a positive effect on tacit knowledge sharing (informal).
H4d. The mistake acceptance component of constant learning culture has a positive effect on tacit knowledge sharing (informal).
Following the distinction noted by Polanyi (1966) between tacit and explicit knowledge, Nonaka et al. (2000) transferred this understanding of knowledge to the business context introducing SECI model. Next, Nonaka and Takeuchi (2019) developed socialization, externalization, combination and internalization model, which emphasizes that organizational continuous innovation is achievable through constantly and repeatedly creating new knowledge (tacit), disseminating this knowledge, and converting it into an explicit form. Thus, the following hypothesis is proposed: H5. Tacit knowledge sharing has a positive effect on formal explicit knowledge processes.
3.4 Knowledge processes support intellectual capital creation IC is conceptualized as knowledge-based assets that organizations use to achieve and maintain a competitive advantage (Yang et al., 2015). Knowledge management processes and IC affect one another (Seleim and Khalil, 2011). IC results from the intangible assets of knowledge and social relationships (Jardon, 2015). The intangible assets of today are vital sources of innovativeness, which is the key driver to ensure long-term organizational competitiveness (Tsui et al., 2014). Moreover, intellectual assets are defined as the "stock of knowledge" possessed by an organization and comprises human, structural, and relational capital (Bontis, 1998). Human capital is related to employees' knowledge, capabilities, education level, soft and professional skills, and other personal characteristics. Structural capital reflects the entire knowledge infrastructure of an organization (Hussinki et al., 2017). The explicit knowledge acquisition and management of an organization are fundamental parts of structural capital (Abualoush et al., 2018). Structural capital is perceived as an effect of explicit knowledge integrated into information systems and as the result of knowledge conversion (Asiaei et al., 2018). Relational capital accumulates internal and external relationships as a source of potential value (Kianto and Waajakoski, 2010). Additionally, the renewal capital component of IC, introduced by Kianto (2008), reflects the general organizational ability to learn and acquire new skills and capabilities.
Furthermore, Saint-Onge (1996) noted that tacit knowledge has different forms for each organizational IC component: for human capital, tacit knowledge is reflected in mindsets, assumptions, beliefs, and biases; for relational capital, tacit knowledge is reflected in the collective mindsets of meaning perception; and for structural capital, tacit knowledge is reflected in the collective culture, norms, and patterns of behavior (p. 12). Vagnoni and Oppi (2015) argued that newly created knowledge strongly supports structural capital. At the same time, formal knowledge management processes support structural capital creation (Abualoush et al., 2018). Thus, IC is a result of formal and informal knowledge processes and is the focal point of organizational performance. As a result, hypotheses that both formal (related to explicit knowledge) and informal (related to tacit knowledge) knowledge processes support IC are proposed. Further, Wang et al. (2014) demonstrated that the effects of tacit and explicit knowledge on specific IC components differ. Thus, the hypotheses are divided into tacit and explicit knowledge as follows: H6a. Tacit knowledge sharing has a positive effect on human capital.
H6b. Tacit knowledge sharing has a positive effect on relational capital.
H6c. Tacit knowledge sharing has a positive effect on structural capital.
H7a. Explicit knowledge processes have a positive effect on human capital.
H7b. Explicit knowledge processes have a positive effect on relational capital.
H7c. Explicit knowledge processes have a positive effect on structural capital. Agostini and Nosella (2017), Buenechea-Elberdin et al. (2018), and Oliveira et al. (2020) considered human capital an antecedent of relational capital. In addition, Kianto (2008) and  argued that renewal capital (reflecting the general organizational ability to learn and acquire new skills and capabilities) is supported by human capital. Thus, the following hypotheses are put forward: H8a. Human capital has a positive effect on relational capital.
H8b. Human capital has a positive effect on renewal capital. Santos-Rodrigues et al. (2013) noted that the human and relational components of IC are important for innovation development, and the relational and structural components of IC are vital for innovation adoption, demonstrating that relational capital is critical. Moreover, Buenechea-Elberdin et al. (2018) revealed that relational capital positively affects renewal capital. Therefore, the following hypothesis is formulated: H9a. Relational capital has a positive effect on renewal capital.
The relational capital component of IC includes all company relationships (Meles et al., 2016). It can be perceived as a mandatory source of structural capital understood as infrastructure for value creation by sharing, using and transferring existing knowledge (Sullivan, 2000). Moreover, Lervik (2006) argued that structural and relational capital are interrelated. Thus, the following hypothesis is developed: H9b. Relational capital has a positive effect on structural capital.

Intellectual capital fosters organizational innovativeness
Innovative ideas are at the center of organizational efforts aimed at delivering superior market performance and securing sustainable competitive advantages (Cillo et al., 2019). IC is a source of innovation (Campanella et al., 2014). Renewal capital (Kianto, 2008) is in line with Senge's (2006) idea that learning organizations have a shared vision of organizational aims, Leadership, culture, intellectual capital and that open-mindedness accommodates diverse viewpoints, experimenting, questioning existing assumptions, and shared beliefs to promote continuous innovation. The direct and positive effect of IC on organizational innovativeness was demonstrated (Cabrilo et al., 2018). Buenechea-Elberdin et al. (2018) showed that structural capital has a positive effect on renewal capital and that renewal capital supports organizational innovation performance. Therefore, the following hypotheses are formulated: H10. Structural capital has a positive effect on renewal capital.

H11
. Renewal capital has a positive effect on organizational innovativeness.

Control variables
A control variable is an additional factor possibly affecting the relationship between an independent and a dependent variable. As a result, a control variable may act as a confounder, moderator or suppressor (Spector and Brannick, 2011). Such an important variable for this study is tacit knowledge awareness. According to El-Den and Sriratanaviriyakul (2019), tacit knowledge awareness is simply the stage at which an individual realizes something new (e.g. opinion/idea). Social interactions foster awareness and the development of new concepts (Nonaka et al., 2000). Therefore, the tacit knowledge awareness moment is promoted by general socialization i.e. task-related interactions and overall formal, informal and unformal organizational social interactions (Insch et al., 2008). Moreover, Kremer et al. (2019, p. 67) highlighted that "if new ideas are not articulated, they can hardly be implemented." So, the lack of tacit knowledge awareness may disrupt its sharing. Therefore, it is considered a moderator in this study (Hayes, 2018). Thus, the following hypothesis is proposed: Hcv1. Tacit knowledge awareness moderates the effect of learning culture on tacit knowledge sharing.
This study also aims to control the industry factor. Kucharska and Erickson (2020) empirically demonstrated that the industry factor is important for knowledge-sharing studies. Therefore, the comparison between involved in the study sectors seems to be fascinating. Specifically, all sectors included in this study (information technology [IT], healthcare, higher education [HE], construction) are defined as knowledge-based industries, but IT, healthcare, and HE are defined as knowledge-intensive industries (Lee and Jung, 2020). The above industries are driven by knowledge but in a different (industrial) context. Therefore, the following hypotheses are proposed concerning the potential effect of industry factors on informal tacit knowledge sharing and formal knowledge processes: Hcv2a. Industry factor determines informal tacit knowledge sharing.
Hcv2b. Industry factor determines formal knowledge processes.

Sample
The sampling process focused on recruiting knowledge worker staff from the IT, construction, HE and healthcare industries in Poland. The sampling plan included independent samples composed of HE (n 5 368) and construction, healthcare, and IT (n 5 350 each) professionals. It was designed according to the statistics concerning the labor market (Statistics Poland, 2017). All samples were characterized by gender and position balance. The data were collected in January and February 2020.

Measures
All included constructs represented by latent variables were measured using existing attitude scales (Appendix B). The new scale for knowledge processes measurement was introduced in this study and validated according to deVellis's (2017) procedure. The survey began with questions about the workers' qualifications to ensure the selection of respondents who: first, had been employed for a minimum of one year by the same company perceived by them as a "learning organization"; and second, had a "knowledge worker" status, which concerns positions where knowledge is a tool and the result of their work (input and output of their working processes). Respondents were given a brief explanation of the purpose of the study, and definitions of a learning organization, knowledge worker, and tacit knowledge. They were then asked to react to focal statements measuring all involved constructs using a seven-point Likert scale to assess respondents' attitudes to these statements. Further analysis only included fully completed questionnaires with SD > 0.4. Appendix C includes descriptive statistics. The measured constructs reached (standardized) indicator loadings above the reference level of >0.6 (Hair et al., 2010). Internal consistency of the constructs was assessed using Cronbach's alpha and a critical level of >0.7 (Francis, 2001). Average variance extracted (AVE) was assessed with a test statistic of >0.5 and composite reliability of >0.7 (Byrne, 2016), with all establishing scale validity. Discriminant validity was assessed by comparing the AVE square root against correlations with other constructs (Fornell and Larcker, 1981). All AVE coefficients were appropriately larger than the reference value. Appendix D presents details.

Procedure
The analysis procedure began with an assessment of the structural model quality for total Poland. The control variable "industry" (nominal) was input to the total Poland model, and after the positive result achievement (β 5 À0.10***), separate models were created to identify differences between industries. Given that tacit knowledge awareness was included as a control variable and was also significant for the total Poland sample (β 5 0.17***), it was also imputed for industry models. Next, all obtained results were analyzed and discussed.

Results
The most interesting findings concern the effect of knowledge processes on IC. Formal and informal knowledge processes were found to affect different IC components. Specifically, formal knowledge processes are not significant for relational capital, which is observed for all four industries under analysis (H7b). Similarly, formal knowledge processes are not significant for human capital (H7a), except in the HE and IT industries, but this support is not very strong (β 5 0.11*/0.13*). This implies that formal knowledge processes do not support human-related components of IC. In contrast, informal tacit knowledge sharing has a positive effect on all IC components (H6a), with the most potent effect observed for HE and healthcare (β 5 0.61***/0.65***). However, its influence on the structural component (H6c) is comparably weaker and not significant in the construction and HE industries. This implies that informal knowledge sharing supports human-related components of IC. Further, formal knowledge processes support the structural component, which is observed for all four industries under analysis (H7c). This implies that formal knowledge processes, in contrast to informal, strongly support the structural capital component. Renewal capital is strongly supported by human and structural capital (H8b and H10), whereas the positive effect of the relational component on renewal capital is noted only in the healthcare industry (H9a). This study reveals a strong effect of renewal capital on innovativeness for all four industries under consideration (H11). This highlights the importance of renewal capital for innovativeness. Another important finding was the influence of knowledge culture and learning culture on formal and informal knowledge processes. The study finds that knowledge culture strongly influences the climate component of learning culture (H3b), and this relationship applies to all four industries. In contrast, the mistakes acceptance component of learning culture is strongly supported by knowledge culture in the construction and HE industries (H3a). For the healthcare industry, this relationship is weaker but still significant, and it is insignificant for the IT industry. Thus, the mistakes acceptance component of learning culture is not equally observed in all four industries, meaning that the potential of mistakes as a source of learning is not likely to be equally used in industries as a potential source of tacit knowledge awareness.
Moreover, the results demonstrate that knowledge culture strongly supports formal knowledge processes (H4a) and significantly and strongly supports informal tacit knowledge processes for the healthcare industry (H4b). For the IT industry, this relationship is weaker, and it is not significant for the construction and HE industries. In addition, it was discovered that learning culture is more important than knowledge culture for informal tacit knowledge sharing (H4c-d). The climate component of learning culture is found to have a significant and direct effect on tacit knowledge sharing in the construction, HE and IT industries (H4c). This effect is not significant in the healthcare industry. In contrast, the climate component of learning culture supports the mistakes acceptance component of learning culture in the healthcare and IT industries, but not in the HE and construction industries (H1c). This means that in the HE and construction industries, the acceptance of mistakes does not result from the learning climate component. In contrast to the construction and HE industries, learning climate significantly supports mistakes acceptance in the healthcare industry, and the relationship between learning climate and tacit knowledge sharing is fully mediated by mistakes acceptance (indirect effect 5 0.20(***)-two-tailed BC significance). Further, the acceptance of mistakes directly supports tacit knowledge sharing in the HE, healthcare, and construction industries, but not in the IT industry (H4d); however, learning climate supports mistakes acceptance in the IT industry (H4c). Thus, this issue is interesting and requires a more in-depth investigation. Moreover, in regard to the effect of knowledge culture on knowledge processes, the effect of tacit knowledge awareness on tacit knowledge sharing is the strongest in the healthcare industry (Hcv1), where the learning culture is the strongest and fully supported by the mistakes acceptance component.
Regarding leadership issues, it was found that transformational leadership significantly affects knowledge and learning cultures in all four analyzed industries (H1a-b, H2). However, while knowledge culture and learning climate are supported equally strongly by transformational leadership (H1b, H2), the mistakes acceptance component is supported by transformational leadership to a lesser extent. This suggests that the mistakes acceptance component of learning culture may be controversial for companies with strong knowledge culture. Specifically, companies where knowledge is highly valued may find it difficult to accept the fact that mistakes occur. This is in line with the learning paradox described by Kucharska and Bedford (2020). Figure 2 presents all the obtained results. All details of verifying the hypotheses are presented in Table 1.

Discussion
The results illustrate the "big picture" of all of the identified micromechanisms linking transformational leadership with organizational innovativeness. These micromechanisms (1) clarified how the IC components are created in the relation to knowledge processes; (2) explained the "knowledge paradox"; (3) exposed that IC development is industry-specific; (4) delivered empirical proof that learning culture influences organizational innovativeness.
This contribution allows theory and practice to be expanded regarding organizational innovativeness. These findings are elaborated on below.

Knowledge paradox is explained by the difference in intellectual capital components creation
The most interesting finding of the study is that formal knowledge processes affect structural capital but are not significant in the development of human and relational capital. In contrast, the informal processes of tacit knowledge sharing have a far greater effect on human and relational capital than on structural capital. This finding is in line with Mabey and Zhao (2017), who found that more formal knowledge processes lead to less effective knowledge exchange. Mabey and Zhao (2017, p. 43) revealed that "the more knowledge is formally managed, the less likely effective knowledge exchange will occur" (i.e. "knowledge paradox"). They noted that for organizations of all types (i.e. business and science-oriented), benefits from explicit knowledge management are supported by an appropriate set of processes. However, such processes are not effective for tacit knowledge utilization. The present study Leadership, culture, intellectual capital  (746) 1931.221 (711) 1421.01 (638) 1577.79 (602) 1388 ( Table 1.

Hypothesis verification details
Leadership, culture, intellectual capital sheds light on this by explaining why this paradox occurs. Based on the results, formal knowledge processes support human capital development only in the IT industry (β 5 0.13*), and these processes are ineffective for relational capital creation, even in the IT industry. However, voluntary tacit knowledge sharing significantly supports human and relational capital in all industries. Still, the influence of tacit knowledge sharing on structural capital is weak for healthcare and IT (β 5 0.16*/both), and it is not significant in the HE and construction industries. In contrast, formal processes are not effective for the human and relational components of IC. Wang et al.'s (2014) quantitative study in the context of technology companies in China also identified the lack of a significant effect of explicit knowledge sharing on relational capital, but noted its significant effect on human capital.
6.2 Intellectual capital creation is industry-specific Presented results exposed that IC development is industry specific. The IT industry is exceptionally peculiar about IC creation through formal and informal knowledge processes. This specificity is also clear when the mistakes acceptance component of learning culture is considered. This component is not supported by knowledge culture in the IT industry and does not support informal tacit knowledge sharing, whereas the learning climate component supports informal tacit knowledge sharing in IT. Thus, the unique results of the present study and of Mabey and Zhao (2017) show that the IT industry should be studied in greater depth.
There are also interesting conclusions that apply to the construction industry, particularly given that the R 2 level obtained for this industry was half (R 2 5 24%) of that obtained for the healthcare, IT and HE industries (47%, 46% and 55%, respectively). In the construction industry, transformational leadership supports learning culture more than it supports knowledge culture. Further, learning climate significantly affects tacit knowledge sharing, which influences human and relational capital and does not influence structural capital, whereas it does in IT and healthcare. The other difference between the construction industry and other industries is that although human capital is strongly created by tacit knowledge sharing and strongly influences relational capital, its effect on structural capital is only significant to a lesser extent, and it does not support renewal capital. In the construction industry, structural capital is supported by formal knowledge processes and is the main source of renewal capital. Thus, external innovativeness in the construction industry is created by a source similar to that in the IT industry (i.e. mainly from new technologies created outside the company). While innovativeness is supported from the outside in the healthcare industry, it is principally fostered by human and relational capital from inside the organization (i.e. from dynamic intelligence and cooperation). This might be the result of the working environment. The IT and construction industries are more static and predictable than the healthcare industry, which requires knowledge to be in use on a continuous basis.
Striking findings are observed for the HE industry. Formal and informal knowledge processes support human capital. Still, their effect on renewal capital is much lower than that observed for healthcare and IT. Further, the observed influence of the human component on HE is the weakest among all of the analyzed industries. Relational capital in HE barely supports structural capital and, ultimately, does not support the renewal component. This means that even though human capital in the HE industry is more efficiently created and prominently supported by leadership, company culture, and knowledge processes than in other industries, it is not exploited effectively. The highest obtained innovativeness for HE could be even higher if the human capital component supported relational capital to a greater extent. Thus, the weakest part of IC creation in HE is internal relational capital. Still, it is generally a grave problem that is observed for all industries involved in this study, except for healthcare.
In summary, the presented R 2 for the models of involved industries (Table 1) shows that the examined relations structure explains the explored phenomenon significantly differently for all included industries. Namely, the whole model explains external innovativeness in 55% for HE; for healthcare and IT, it is 47% and 46%, respectively, and only 24% for the construction industry. So, it exposes that IC development leading to innovativeness thanks to formal and informal knowledge processes is industry-specific.
6.3 Learning culture meaning for innovativeness is empirically proved Following Watkins and Kim (2018), the Introduction section noted that if the assumption that organizational learning culture enhances knowledge creation and innovation is empirically confirmed, it is a highly significant discovery. The theoretical consequences of the findings concerning the "knowledge paradox" identified by Mabey and Zhao (2017) deliver this evidence. Namely, this paradox is explained due to the identified structure of micromechanisms linking transformational leadership with organizational innovativeness. The essence of the presented explanation is an important element of delivering empirical evidence for learning culture's influence on innovativeness. That is, the presented knowledge paradox's essence is that the particular components of IC are created due to different knowledge processes; specifically, human and relational capital are created mostly informally, whereas structural capital is created mostly formally. Therefore, organizations focusing on formal knowledge processes may lose the tacit knowledge created by informal processes that are strongly supported by learning culture. This study revealed that learning culture and tacit knowledge sharing are vital for IC's human and relational components. It showed that the renewal component supported by other components is vital for innovativeness. Hence, this study demonstrates the importance of learning culture for all IC components and shows how these components are connected and how vital they are in terms of organizational innovativeness. Thus, the expected empirical proof of learning culture's influence on innovativeness has been delivered.

Implications, future research and limitations
The general practical context of the study findings suggests that for the effective development of all IC components, organizations must think and act more holistically and support the formal and informal flow of knowledge equally. Therefore, organizations must create formal solutions supporting a company culture that is focused not only on the management of knowledge assets (knowledge culture), but also on knowledge creation (i.e. on learning culture that fosters an appropriate climate and includes a mistake acceptance component).
In summary, the existing differences between different industries leave significant room for further studies in gender or national contexts and their interpretation. The issue of why tacit knowledge sharing in the IT industry is apparently weaker than in the healthcare and HE industries, but the IT industry is still one of the most innovative industries, remains unexplored. Is leadership the essence of IT success? Strong leaders established giants such as Apple, Microsoft, Facebook, and Amazon. The main reason might be the one mentioned abovethe nature of work (clear rules, mathematical algorithms, logic)in which case the "industry" control variable becomes the primary determinant for the type of knowledge sharing (explicit vs tacit, formal vs informal) and could imply different patterns of IC creation and its relation to the innovativeness of the companydepending on the industry sector. It might also be that the national context, including national culture and the maturity level of a particular industry, is important in terms of further findings. This issue is undoubtedly fascinating and deserves further investigation.

Leadership, culture, intellectual capital
The principal limitation of the studyapart from the omission of external relational capital and the potential effect of the existing domination of men in the IT and construction sectorsis that this study was conducted in the context of only one country. Thus, the results may not be generalizable to other countries. Future research could include a cross-country study to shed light on the explored mechanisms of the effect of transformational leadership on company culture, knowledge processes, IC and innovativeness in knowledge-intensive organizations.

Conclusions
The essence of this study was the exposition of the overall relationship between leadership and innovativeness. Therefore, the current study presented the "big picture" of all IC creation micromechanisms linking transformational leadership with organizational innovativeness. As a result, it explained empirically the "knowledge paradox" identified by Mabey and Zhao (2017, p. 43), according to which "the more knowledge is formally managed, the less likely effective knowledge exchange will occur." The idea behind this paradox is that IC components are created informally (i.e. human and relational) and formally (i.e. structural). Therefore, organizations that focus too much on formal knowledge processes might lose the tacit knowledge created by informal processes. To avoid this, leaders must support both knowledge culture and learning culture. Learning culture encourages tacit knowledge sharing, which is vital for the growth of IC's human and relational components. At the same time, knowledge culture fosters formal knowledge processes for structural component development. Therefore, transformational leaders should equally support learning culture and knowledge cultureand, thanks to this effort-formal and informal knowledge processes to develop intellectual capital. This is vital for innovativeness and organizational development as a whole.
