The central role of networks in advancing organizational and individual goals is well accepted (Adler & Kwon, 2002; Hite & Hesterly, 2001) in the management and sociology literatures. Networks are made up of two distinct types of ties: strong ties and weak ties. Strong ties refer to the network relationships that are close, stable and binding (Ibarra, 1993), as opposed to weak ties, that are more superficial and lacking in emotional investment. Network theory, however, suggests that strong ties may not provide the most beneficial opportunities for an individual/organization (Burt, 1997; Coleman, 1988) and conclude that in order for a business to succeed the entrepreneur must have a network made up of weak ties.

This paper examines how weak ties and strong ties in the supply chain network influence the financing performance of small and medium enterprises (SMEs) through the mediation of information sharing and innovation capability.

Questionnaires were administered to 208 financial managers responsible for supply chain finance in SMEs in China. Data analysis techniques used included multiple regression analysis and fuzzy-set qualitative comparative analysis.

The authors found that weak ties had a more substantial impact on the financing performance of SMEs than strong ties did. Information sharing and innovation capability played a mediating role between weak and strong ties and the financing performance of SMEs. In addition, information sharing and innovation capability complement each other and jointly influence the financing performance of SMEs.

SMEs are suggested to actively embed themselves in the supply chain network to increase financing opportunities and reduce financing costs. The authors also recommend SMEs to enhance the level of their information sharing in the supply chain network and take advantage of their network ties to access and adopt new technology from other organisations and conduct collaborative innovation with partner institutions.

The paper extends the authors’ understanding of supply chain finance by exploring the intrinsic mechanism of how various constructs (weak ties, strong ties, information sharing and innovation capability) in the supply chain network have an impact on the financing performance of SMEs. In particular, the authors explore the under-researched mediating effect of information sharing and innovation capability on the relationship between network ties and the financing performance of SMEs.

This study aims to investigate the relationships between the different strengths of ties (strong ties and weak ties), types of trust and project performance in megaprojects.

A questionnaire survey was conducted with various experts and professionals involved in megaprojects, and 350 valid responses were received. Data was analyzed by means of structural equation modeling.

The results show that both strong ties and weak ties have positive impacts on trust in megaprojects, but weak ties have a more significant positive effect than do strong ties. Unexpectedly, the introduction of interorganizational trust significantly weakens the effect of the strength of ties on project performance. The indirect influence of the strength of ties on performance has different paths. Weak ties have an indirect effect via calculative trust and relational trust. However, in a strong ties network, inferior stakeholders lack the information necessary to complete a megaproject, and they believe that calculative trust will not promote project performance until the megaproject is successfully delivered. Thus, the effect of calculative trust on project performance is not significant.

These findings provide evidence in regard to strength of ties governance being a part of the effective strategy in improving megaprojects’ performance. It also demonstrates the mediating function of trust and advances the current understandings of the underlying mechanism of the strength of ties on project performance, thus providing implications for researchers and practitioners. However, this study has some limitations. For example, the strength of ties and trust between organizations are a dynamic process in megaprojects. This study does not conduct in-depth analysis of the evolution mechanism and investigate the different levels of trust at different stages of the megaproject. Future research can be guided by these directions.

The main contribution of this study is fourfold. First, this study enriches the literature on strength of ties by accentuating the roles of trust in megaproject context. Second, this study contributes to the theoretical development of a conceptual model for explaining the interrelationships among strength of ties, types of trust and project performance. Third, this study responds to the call “which dimension (i.e. strong ties or weak ties) is more influential” by exploring the direct and indirect effects of strength of ties on project performance. Finally, this study breaks through the limitation of traditional cognition that megaproject management can be met by relying on rigid contracts. In other words, trust can supplement the weakness of rigid contract by forming contract flexibility with different strength of ties. Meanwhile, the specific strategies to establish and maintain trust are given, such as building information model (BIM) collaboration platform and reputation management mechanism.

This study aims to explore the influence of the strength of ties (strong ties and weak ties) on contractual flexibility (term flexibility and process flexibility) and relationship quality among stakeholders in a megaproject network.

This study, via a questionnaire survey, collected 380 valid responses from megaproject professionals (including project managers, department managers and project engineers). The data were analyzed using least squares structural equation modeling.

The results show that both strong ties and weak ties have positive effects on relationship quality. The introduction of contractual flexibility can help improve relationship quality by combining the positive effects of the strength of ties. Interestingly, the indirect influence of strong ties on relationship quality is mainly due to term flexibility. However, the influence of process flexibility is not significant, while weak ties have an indirect influence through term flexibility and process flexibility.

This study, while helpful to megaproject management both in theory and practice, is nevertheless subject to several limitations. First, this study only considers the impact of the strength of ties on contractual flexibility and relationship quality; other factors, such as environmental uncertainty, are not explored. Second, the sample data are limited to just a few regions of China. Future research should cover other influencing factors, in order to make the model more substantial; data should also be collected from different cultural and industrial sources, thereby extending and further verifying the results.

This study makes three contributions to extant megaproject literature. First, this study provides a deep and nuanced understanding of the strength of ties. With the distinction between strong ties and weak ties clearly explained, this research furnishes a subtler understanding of relationship governance than has previously been achieved. Second, by precisely identifying the mechanism of how contract flexibility improves contract control and coordination functions, this research offers a complementary view of how contractual flexibility positively contributes to cooperation and relationship quality. Third, this study identifies which dimension of the strength of ties is more influential. This brings a new explanation for the previous controversy and offers some insight into the determinants of how to improve relationship quality in Chinese megaprojects.

The purpose of this study is to contrast the effects of four exit barriers on word of mouth activities. Monetary, service loss, social and convenience exit barriers are compared. The differential effects of these four barriers on the valence of word of mouth (positive, negative), the type of word of mouth recipient (weak tie, strong tie) and the motives (catharsis, company sabotage) for spreading word of mouth are studied.

The data for empirically addressing a set of hypotheses were collected from 185 consumers. The hypotheses were analyzed using ANOVA models along with post hoc tests.

The results suggest that the type of exit barrier matters. Exit barriers, with respect to word of mouth activities, seem to fall on a continuum. On one extreme, the most detrimental barriers are monetary hurdles, and on the other end, the least detrimental barriers are convenience hurdles. Monetary barriers are responsible for the most negative word of mouth and company sabotage. Social and convenience barriers lead to significantly less.

The implications for erecting exit barriers are discussed. In particular, the value of monetary barriers is questioned. The benefits of such involuntary customer retention methods may be offset by the sabotage they invite through negative word of mouth.

The paper provides insights into word of mouth activities of dissatisfied customers that are trapped by various exit barriers. The word of mouth activities investigated include valence, recipient type and motives. The study contrasts monetary, service loss, social and convenience exit barriers.

This study aims to explore the impact of firm-generated content (FGC) on viral marketing on multiple social media platforms, and how social ties embedded in different social media platforms affect the motives for social dissemination.

Three studies were conducted to test the model. A quasi-field experiment (Study 1) supported this main effect. Studies 2 and 3 examined the underlying mechanism and enhanced the internal and external validity of the findings.

The findings revealed that warmth (vs competence)-oriented FGC is consistent with the communion (vs agency) mode and elicits greater social dissemination on social media embedded with strong (vs weak) ties.

This study illustrates that FGC that matches communication modes on multiple social media platforms embedded with different social ties will trigger viral marketing and being aware of this match is crucial for policymakers.

This research sheds light on the effects of FGC on viral marketing on multiple social media platforms embedded in different social ties.

Networking and being a part of an established business network supports the process of translating new ideas into marketable solutions and acquiring customers. The purpose of this paper is to investigate how aspiring entrepreneurs in a Danish rural area setting manage to get embedded into relevant business networks. Before the literature background on social capital and regional development, the authors use the embeddedness approach in explaining whether weak or strong ties are most beneficial to get the business started and how lacking strong ties can be compensated.

This paper takes an economic sociology perspective on social capital and is empirically based on a case study. The sample consists of a group of young aspiring entrepreneurs, living in the rural area of Southern Jutland, who are all committed to an organization which supports regional start-ups.

The authors found that aspiring entrepreneurs have different needs depending on their development status and type of innovation. Founders, who are developing or have developed new product innovations, seem to have an increased need for “strong ties” with consultants and those with knowledge about building up a professional network. Founders, who are developing or have developed a significantly improved service, have strong ties with former fellow students and researchers at the university.

This study illustrates that aspiring entrepreneurs connected to a regional entrepreneurship center gained access to a wider relevant network. Depending on their level of embeddedness, they could build new strong relationships and exploit information stemming from new “weak ties” and as such harness more benefits. The study shows that less privileged start-ups can substitute strong ties, especially through the support of professional managers of startup-supporting organizations. Finally, a model explaining the impact of social capital on the entrepreneurial sphere of regional business networks and on its innovativeness is deduced.

As an effective mode to help small and medium enterprises (SMEs) raise working capital, supply chain finance has recently gained extensive attention. The purpose of this paper is to explore the intrinsic mechanism of how both weak and strong ties in the supply chain network impact the supply chain financing performance (SCFP) of SMEs from the perspective of the supply chain network.

Based on the extended resource-based perspective, this paper proposes a theoretical model to explain the mode in which strong ties and weak ties of SMEs in the supply chain network influence SCFP through both physical distribution flexibility and demand management flexibility. Based on data from 182 manufacturing firms in China, this paper uses multiple regression analysis to test hypotheses.

The results of this paper indicate that weak ties improve SCFP more effectively than strong ties. Furthermore, both physical distribution flexibility and demand management flexibility exert different mediating roles either between strong ties and SCFP or between weak ties and SCFP. Moreover, the effect of physical distribution flexibility and demand management flexibility on SCFP of SMEs is not reinforced.

This paper highlights the importance to expand supply chain finance research from the perspective of the supply chain network. In particular, this paper explores the poorly understood mediating effect both physical distribution flexibility and demand management flexibility exert on the relationship between network ties and the SCFP of SMEs.

This study aims to investigate how the strength of ties (i.e. strong ties and weak ties) in megaproject networks influences project performance in terms of types of conflicts.

A questionnaire survey was undertaken with professionals in Chinese megaprojects and 445 valid responses were received. A conflict-based theoretical model was developed and tested with structural equation modeling.

The results indicated that task conflict had a constructive effect on project performance, whereas relationship conflict and process conflict had destructive effects. Both strong and weak ties positively affected project performance, and that weak ties exerted greater effects on performance. The introduction of conflicts significantly weakened the effect of strong ties on project performance. Strong ties indirectly affected project performance via task conflict and relationship conflict, whereas weak ties affected performance only through task conflict. Task conflict had a constructive effect on project performance, whereas relationship conflict and process conflict had destructive impact.

This study identified the positive effect of strength of ties on project performance as well as the constructive and destructive roles of conflicts. Furthermore, the findings provided evidence that strength of ties and conflicts were critical factors for project performance. While, there are still limitations. There are other attributes of megaproject networks, such as network nodes’ characteristics and network structure, which may influence conflicts and project performance. Future research would be conducted to explore the role of these variables. Meanwhile, because different types of conflicts may mutually transform under certain conditions, future research would also address this issue in megaprojects.

As for the management strategies, project stakeholders should know the existence of project networks, exactly assess their resource endowment, especially their external and internal relationship network. In accordance with changes of the project network, stakeholders should share knowledge and learn techniques about how to respond to relationship disturbances, thus reducing relationship conflict and process conflict. Furthermore, stakeholders should place an emphasis on fostering and reinforcing communication and trust, thus effectively resolving task conflict, ambiguity and uncertainty engendered from network ties in a megaproject network.

The main contribution of this study is threefold. First, this study will enrich the literature on strength of ties by accentuating the roles of conflicts in megaproject context. Second, this study contributes to the theoretical development of a conceptual model for explaining the interrelationships among strength of ties, conflicts and project performance. Third, this study will respond to the call “which dimension, i.e. strong ties or weak ties, is more influential” by exploring the direct and indirect effects of strength of ties on project performance.

Social networking sites (SNSs) offer people the possibility of maintaining larger networks of social ties, which also entails more complex relationship maintenance across multiple platforms. Whom to “friend” and via which platform can involve complex deliberations. This study investigates the relationships between users' perceived friending affordances of five popular SNSs (Facebook, Twitter, Instagram, Snapchat and LinkedIn) and their friending behaviors concerning strong ties, weak ties (existing and latent ties) and parasocial ties.

An online survey using Qualtrics was provided to participants (N = 626) through Amazon's Mechanical Turk (MTurk). The survey asked their SNS use and their friending behaviors with different ties on each of the sites.

Users' friending decisions are dependent on an interplay of socio-technical affordances of each SNS and specific needs for the ties. The authors found that the affordances of bridging social capital and enjoyment are aligned with friending weak and parasocial ties, respectively. The affordances of bonding social capital were not valued to friend strong ties.

The study extends the affordance and social capital literature by assessing users' perceived, contextualized SNS affordances in relation to actual communication behaviors in friending different social ties. This approach provides contextualized insights to friending decisions and practices on SNSs.
