As knowledge management increasingly becomes critical for the success of professional service firms, this paper uses social exchange theory to investigate the interactive impact of transformational leadership and organizational innovation on online knowledge sharing by employees in professional service firms. This study aims to investigate the mediating roles of job autonomy and job engagement in this process.

Data were collected from a survey of 350 frontline employees in professional service providers, including banking, telecommunication and insurance. Structural equation modeling was used for data analysis.

The results show that transformational leadership positively affects job autonomy, which in turn has a positive impact on online knowledge sharing through job engagement. Thus, job autonomy and job engagement mediate the relationship between transformational leadership and online knowledge sharing. Finally, organizational innovation moderates the relationship between transformational leadership and job autonomy.

This paper extends the knowledge management literature by studying the impact of transformational leadership on the online knowledge-sharing behavior and exploring the focal roles of job autonomy and job engagement in online-sharing behavior in professional service firms. The findings also provide useful implications for practitioners to help them engage employees in the adoption of digital technologies to optimize outcomes.

Free knowledge sharing in the online health community has been widely documented. However, whether free knowledge sharing can help physicians accumulate popularity and further the accumulated popularity can help physicians attract patients remain unclear. To unveil these gaps, this study aims to examine how physicians' popularity are affected by their free knowledge sharing, how the relationship between free knowledge sharing and popularity is moderated by professional capital, and how the popularity finally impacts patients' attraction.

The authors collect a panel dataset from Hepatitis B within an online health community platform with 10,888 observations from April 2020 to August 2020. The authors develop a model that integrates free knowledge sharing, popularity, professional capital, and patients' attraction. The hierarchical regression model is used to for examining the impact of free knowledge sharing on physicians' popularity and further investigating the impact of popularity on patients' attraction.

The authors find that the quantity of articles acted as the heuristic cue and the quality of articles acted as the systematic cue have positive effect on physicians' popularity, and this effect is strengthened by physicians' professional capital. Furthermore, physicians' popularity positively influences their patients' attraction.

This study reveals the aggregation of physicians' popularity and patients' attraction within online health communities and provides practical implications for managers in online health communities.

This study aims to examine the differences in the impact of three leadership styles (transactional, transformational and creative) on intraorganizational online knowledge-sharing and employee creativity. Specifically, we use self-determination theory (SDT) to examine the impact of these three leadership styles on four aspects of online knowledge sharing (knowledge donating, knowledge collecting, lurking and active lurking) and the moderating role of organizational innovation on these relationships.

Data were collected from 361 employees of business-to-business organizations in Vietnam to support all our hypotheses. Structural equation modelling was used for data analysis.

Transformational, transactional and creative leadership were found to affect online knowledge sharing, wherein creative leadership had the most potent effect. Online knowledge sharing was found to mediate the impact of three types of leadership on employee creativity. The results also showed that organizational innovation moderates the influence of leadership on online knowledge sharing.

This paper extends the current knowledge management research on online knowledge sharing by studying two new behaviors (lurking and active lurking), linking diverse leadership styles to these behaviors and employee creativity, and exploring the moderating role of organizational innovation. Our findings shed light on the complexity of the relationship between leadership and online knowledge sharing. This study also provides valuable implications for practitioners to help them choose the most appropriate leadership style for their digitalization process to ensure optimal outcomes.

This paper aims to propose a system dynamics model of blockchain online community knowledge sharing, with the following goals: to reveal the internal mechanism of blockchain technology on community knowledge sharing; to show the impact of blockchain technology on knowledge sharing; and to promote knowledge sharing and the self-development of blockchain online communities.

Based on the core characteristic factors of blockchain technology, including incentive mechanism, trust mechanism, information protection mechanism, etc., a knowledge sharing analysis framework is established. Through the use of the Vensim PLE (Personal Learning Version) software, according to the steps of “putting forward a dynamic hypothesis”, “establishing a system dynamic equations”, and then “model testing” and “simulation”, the article analyzes in depth the process and extent of the impact of the above features on online community knowledge sharing.

The results show that the blockchain incentive mechanism, trust mechanism and information protection mechanism all contribute to promoting an increase in the number of community knowledge sharing users, as well as in the total amount of knowledge shared. The results also show that the token reward in the incentive mechanism has in fact a higher degree of influence than the trust and information protection mechanisms.

At present, no research on the internal mechanism of knowledge sharing in blockchain online communities has been carried out. This article plays a complementary role in research in this field, and offers significant guidance for promoting online community knowledge management and online community development.

Online knowledge sharing is a critical process for maintaining organisational competitive advantage. This paper aims to develop a new conceptual framework that investigates the moderating impacts of innovation on self-efficacy, extrinsic and intrinsic rewards on employees’ online knowledge sharing behaviour in public and private sector companies.

This research analysed 200 responses to test the moderating effects of organisational innovation on the relationship between self-efficacy and rewards and online knowledge sharing behviours. The analysis was carried out using component-based partial least squares (PLS) approach and SmartPLS 3 software.

The results reveal that self-efficacy significantly affects online knowledge sharing behaviour in firms, regardless of the organisation type. Extrinsic rewards encourage employees in private companies to share knowledge online, whereas intrinsic rewards work effectively in public companies. Additionally, the study found the moderating role of organisational innovation in examining the relationship between rewards and online knowledge sharing behaviour.

Future research may consider different dimensions such as knowledge donating and collecting behaviours as well as motives, such as self-enjoyment, reciprocity or social interaction ties, which may be investigated to get a deeper understanding of online knowledge sharing behaviour.

Firms must tailor training and rewards to suit employees’ abilities and needs so as to align with organisation type and innovation.

The study’s distinctive contribution is the under-researched context of Vietnamese public and private sector banks for investigating the moderating effects of organisational innovation on micro and meso factors on online knowledge sharing behaviour.

Online knowledge sharing is a popular activity worldwide and can be leveraged by organisations to innovate, create and sustain competitive advantage. Although there have been a number of studies examining knowledge sharing to encourage employees to convey their skills and experiences to others in an organisation, few attempts have been made to investigate the key motivators of online knowledge sharing in an organisation. Based on the theory of planned behaviour and technological acceptance model, this study aims to review the literature to establish a conceptual framework examining motivators of online knowledge sharing in organisations.

Previous studies that investigated motivators of online knowledge sharing in organisations in the literature were reviewed to propose a conceptual framework.

Four-dimensional model, which includes four types of key motivators of online knowledge sharing, namely, individual, social, organisational and technological, was established.

The model serves as a roadmap for future researchers and managers considering their strategy to enhance online knowledge sharing in organisations.

Knowledge withholding is an important but under-studied topic, which refers to the phenomenon that individuals give less than full effort to contributing knowledge. This study aims to investigate the differential effects of task characteristics on individuals’ knowledge withholding behavior in online space, this study develops and empirically verifies a theoretical model that covers the five core task characteristics in job characteristics model (autonomy, identity, feedback, skill variety and significance), knowledge sharing self-inefficacy and withholding effort in sharing knowledge.

Using an online survey method, this study collected empirical data from 351 general internet users from 30 provincial administrative units in China. The data were analyzed using the structural equation modeling technique of partial least squares.

The analysis results indicate that autonomy negatively affects, while identity, skill variety and significance positively affect users’ knowledge withholding behavior in online space through the mediation of knowledge sharing self-inefficacy, and that three task characteristics (autonomy, identity and feedback) strengthen the relationship between knowledge sharing self-inefficacy and knowledge withholding.

This study provides valuable insights for reducing knowledge withholding behavior in online space. Operationally, different levels of task characteristics such as autonomy, identity and feedback can be set to prevent users from perceiving themselves as inefficacious, and to weaken the behavioral expression of knowledge sharing self-inefficacy.

This study provides a comprehensive understanding of the differential effects of task characteristics on knowledge withholding in online space, and improves the cognition of the boundaries of withholding effort in sharing knowledge in online space.

This study aims to examine the relationship between intrinsic motivation and online knowledge sharing intentions (KSIs) and the moderating effect of extrinsic motivation and organisational culture on this relationship. The influence of online KSI on two dimensions of online knowledge sharing behaviour, knowledge donating and knowledge collecting, was also investigated.

Based on the extensive literature review, a questionnaire was designed. In total, 290 questionnaires from employees in Vietnamese companies in the banking and insurance industry were collected and tested using structural equation modelling. Statistical analysis was conducted using SPSS and PLS 3 software to examine the research hypotheses.

This study found that rewards and reciprocity undermined the influence of self-enjoyment on online KSI, while top management support and social interaction ties undermined the relationship between self-efficacy and online KSI. Top management support positively moderated the effect of self-enjoyment on online KSI. The results also suggested that online KSI was a good predictor of online knowledge donating and collecting.

Little is empirically known about the moderating effect of extrinsic motivation and organizational culture on intrinsic motivation. The study brings new insights to further understand about online knowledge sharing in an organisation.

This paper aims to examine the influence of intrinsic motives (self-efficacy, reputation and reciprocity) on online knowledge sharing behaviour. Additionally, this research investigates the moderating role of individual innovation capability and top management support.

The methodology adopted was a questionnaire survey of employees working in Vietnamese telecommunications companies. A total of 501 employees completed a self-administered anonymous survey using a cross-sectional design. Confirmatory factor analysis and ordinary least squared – based hierarchical regression was used to test the conceptual framework.

Self-efficacy, reputation and reciprocity significantly impact online knowledge sharing behaviour. Specifically, self-efficacy has an inverted U-shape association while reputation and reciprocity have a positively, returns-to-scale association with online knowledge sharing behaviour. Individual innovation capability moderates the effect on these associations as does top management support, but to a lesser extent.

Data were obtained at a single point in time and self-reported. Furthermore, this study was conducted in a specific industry in Vietnam, i.e. telecommunications, which limits the generalisability of the research.

Organisations need to create a favourable environment for online knowledge sharing to foster reciprocal relationships and interpersonal interactions of employees. Encouraging and rewarding employees to actively engage in knowledge exchange will help facilitate reciprocal online knowledge sharing behaviour.

This study contributes to knowledge-sharing behaviour by uncovering an inverted U-shape association and positively, returns-to-scale associations between intrinsic antecedents and online knowledge sharing behaviour. Additionally, individual innovation capability was an important moderator which has been overlooked in past research.

This study aims to explore the factors that affect online knowledge sharing among the scientific performance of academics at the University of Mosul, Republic of Iraq.

Data were collected by using a random sample by means of an electronic questionnaire distributed to 211 academics at the University of Mosul via online platforms. Structural equation modeling was used to test hypotheses using AMOS 24 software.

The results showed that collaboration, perceived flexibility and willingness to share had a significant effect on online knowledge sharing behavior and that which in turn had an effect on the academic performance of respondents, while the results showed no influence of knowledge self-efficacy and communication on the behavior of online knowledge sharing.

In this research, the effects of five factors on online knowledge sharing behavior were studied, in addition to the effect of the latter on academic performance. The research did not study the effect of the participants’ personal characteristics on the behavior of knowledge sharing online, which could be an area of future investigation. The study was limited to online knowledge sharing for academics working in public universities, and the authors suggest conducting a future study from the perspective of medical staff working in hospitals and its impact on their performance.

Based on the findings of the current study, this study suggests that the academic staff at the University of Mosul and similar universities pay attention to scientific cooperation between researchers and teaching staff, by creating online groups to carry out joint research projects that contribute to sharing knowledge among participants through social media in general and scientific platforms in particular. Establishing a scientific research portal could serve this well for example.

Most previous studies have focused on areas related to knowledge sharing in higher education institutions from the traditional perspective and therefore studies that examine the factors affecting online knowledge sharing among academics are limited, so this study fills this gap. This paper focuses on identifying the scientific benefits for academics through knowledge exchange and the use of electronic platforms at the University of Mosul. The study is expected to contribute to enhance the exchange of knowledge online between academics in similar universities in Asia and Africa due to the convergence of cultures and the nature of the work of these universities, as well as the possibility of generalization due to the research’s use of the deductive method.
