Knowledge sharing is a fundamental source of competitive advantage. Social networks are thought to play an important role in knowledge sharing, but are presumed to create a trade-off such that a network can be optimized to promote either knowledge seeking or knowledge transfer, but not both. The trade-off, however, is premised on, and representative of a broader tendency to treat, brokerage and closure as contradictory network forms. We challenge this assertion and propose a theory of knowledge sharing with brokerage and closure as compatible and complementary. Evidence from a contract research and development firm broadly supports our theory. We also report the results of a simulation analysis, which illustrate that only in the extremely rare case when a network is characterized by nearly complete balance do brokerage and closure begin to create a trade-off.

We argue for a broadened approach to brokerage by distinguishing between brokerage emphasizing a particular structural pattern in which two otherwise disconnected alters are connected through a third party (“brokerage structure”) and the social behavior of third parties (“brokerage process”). We explore a processual view of brokerage by examining three fundamental strategic orientations toward brokerage: conduit, tertius gaudens, and tertius iungens that occur in many different forms and combinations. This processual view is especially relevant in increasingly complex and dynamic environments where brokerage behavior is highly varied, intense, and purposeful, and has theoretical implications for studying multiplexity, heterogeneity, and brokerage intensity.

This article explores the contingent role that social ties play in the emergence of status hierarchies. We argue that, while status is formed based on actors’ perception and understanding of social cues, network structure, and position influence this process by influencing the attention and legitimacy given to the focal actor in accordance with social cues that signal an actor’s identity. Using a large data set from an open-source software development community, we find that a broker linking diverse network members is less likely to receive status ratings from others and that the rating is more likely to be low when a broker receives a rating. Furthermore, we find evidence that the effects of brokerage are contingent upon certain factors that may affect the attention and legitimacy given to actors in the process of status evaluation, such as the actor’s prior status. An actor’s prior status was found to weaken the negative effect of brokerage. The importance of this study for theories of status, social networks, and attention is discussed.

This study aims to evaluate the network robustness of major Asian airlines and to explore which airport types have the greatest impact on robustness. We also analyze airports’ specific brokerage roles and their impacts on the robustness of the entire air route network. We select 10 major Asian full-service airlines that operate the main passenger terminals at the top-ranked hub airports in Asia. Data is collected from the Official Airline Guide passenger route dataset for 2017. The results of the network robustness analysis show that Air China and China Eastern Airlines have relatively high network robustness. In contrast, airlines with broader international coverage, such as Japan Airlines, Korean Air, and Singapore Airlines have higher network vulnerability. The measure of betweenness centrality has a greater impact on the robustness of air route networks than other centrality measures have. Furthermore, the brokerage role analysis shows that Chinese airports are more influential within China and Asia but are less influential globally when compared to other major hub airports in Asia. Incheon International Airport, Singapore Changi Airport, Hong Kong International Airport, and Narita International Airport play strong “liaison” roles. Among the brokerage roles, the liaison role has a greater impact on the robustness of air route networks.

Health care ecosystems instantiate different innovation trajectories, driven either by science-/techno-push or user-centric rationales. This article focuses on organization intermediaries (OIs), respectively, active in health care ecosystems driven by science- and techno-push versus user-centric innovation processes; it aims at characterizing their operation and intervention modes. The analysis elaborates on network and content brokerage. Innovation also needs to consider various challenges associated with physical vicinity. The authors check whether territorial anchoring plays a role in brokerage, depending on the innovation model.

The article offers an investigation of eight French organizations matching the definition of OIs and active in different areas of health care-related innovation. It follows a qualitative and abductive research protocol adhering to the precepts of grounded theory.

First, the authors show that content and network brokerage specialize in specific activities in each innovation model. On network brokerage, the authors show that OIs foster the development of communities of practice in the science-/techno-push model, while they nurture communities of innovation in the user-centric model. Services materializing content brokerage are typical consequences of activities performed in each model. The second contribution deals with physical vicinity. In the science-/techno-push model, OIs install a physical space (the “internal” dimension) to support the development of communities of practice, while the “external” dimension copes with agglomeration effects. In the user-centric model, OIs deliver services thanks to the “internal” space; communities of innovation create a leverage effect on the physical space to operate their activities that are supported by “external” network effects.

The originality of the article lies in the description of the alternative roles plaid by organization intermediaries in the science-/techno-push versus user-centric approaches of innovation. In these two approaches, (contents and network) brokerage and physical vicinity play different roles.

Social capital plays an important role in transforming knowledge within and across inter-firm business networks in industries. The purpose of this paper is to explore different kinds of transfer mechanism such as “bonding,” “bridging,” and “protecting” within a case network of the Danish offshore windmill industry. Its aim is to describe how these mechanisms interactively support value co-creation among the involved enterprises and how social capital, residing in the relationships between actors from the firms, is influenced by the different transfer mechanisms.

Based upon a single case study, the paper demonstrates “bonding,” “bridging,” and “protecting” as distinct, yet related, mechanisms for inter-firm business networking. The sample used covers selected key actors from the network as well as third-party experts from the Danish windmill industry, which together represent the most important knowledge-offering and knowledge-demanding domains.

Activities associated with “bridging” and “bonding” clearly matter for creating value for the business network and the industry alike, as they are supportive of strategic capability development (for instance, high-skilled work). While producers and supply companies apply such “bridging,” “bonding,” and additional “protecting” mechanisms based upon their predominant position, small- and medium-sized enterprises (SMEs), however, need to shape teams to do so. A major finding of the study is, thus, that team-based interrelationships among SMEs activate “bridging,” “bonding.” and “protecting” initiatives which are particularly supportive of capability improvement and industry growth. They enable the transfer of relevant capabilities between different projects where actors within SMEs organizations learn to activate and use such knowledge transfer mechanisms. Moreover, asymmetrical dependency-relationships can be partly overcome by shaping and using the mechanisms on the part of SMEs in the network.

To date, brokerage is still an under-explored topic with regard to inter-firm business networks. This case study contributes to the research by illustrating important and distinct qualitative aspects of brokerage, which are conceptualized as “bonding,” “bridging,” and “protecting” initiatives on the part of brokers. The study highlights that not only strong actors with central positions can step into the role as a broker. Even less resourceful actors within asymmetrical relations can act as broker and compensate a lack of resources or strengthen their position within the industry network. Consequently, value co-creating processes within industry networks can also be boosted by brokerage initiated by small companies.

The purpose of this paper is to examine the information flows, in terms of content and process, underpinning the sharing of knowledge by managers and owners. Such an examination reveals similarities and differences that will influence the generation and dissemination of knowledge used in tourism business operations and contribute to innovation.

This paper examines information flows within the theoretical and methodological framework of social network analysis. The findings were derived from a quantitative study of tourism managers and owners of a tourism hub in South-West England.

The main finding was that network structure characteristics determine the flow of information within owners’ and managers’ social networks. The owners of smaller businesses received information from several sources and, therefore, had fewer structural constraints and reported larger structural holes. In comparison, the managers had more brokerage opportunities to disseminate the information within their social networks.

This paper highlights knowledge sharing between tourism business managers and owners in an open network structure. First, an open network structure builds innovation through the provision of nonredundant information. This is determined through the effective size of structural holes and the dissemination of information through brokerage roles. Second, the knowledge capability of a destination is built up through the social networking of managers and owners. The generation and dissemination of knowledge in a tourism destination are facilitated by the social networking activities of managers and owners.

Managers and owners of tourism businesses require knowledge through information to assist with innovative business practices. The practical implication of this is that the social networks of managers and owners have different network characteristics, and that these differences result in consequences for the innovation of business practices. Another practical implication relates to the importance of managers in knowledge dissemination based on having several brokerage roles in the tourism destination.

These findings are important because an understanding of social networks and the flow of information is one of the keys to determining the influences on knowledge sharing within tourism destination knowledge networks of owners or managers and their potential contributions to innovation.

This study aims to identify which actors play leadership and brokerage roles in voluntary environmental collaborations and how the corporate social responsibility (CSR) of actors is associated with such voluntary networking behaviours in Cambodia.

To achieve these purposes, this study mainly uses social network analysis to capture the properties of networking behaviours in the voluntary collaborative activities underlying three main environmental issues: waste disposal, energy and water pollution. The study focusses on the collaborative efforts undertaken by actors across multiple sectors: governmental organizations, for-profits and civil society organizations.

The results show that the government plays the leading role in voluntary environmental collaborations across environmental issues; however, the actual implementation is expanded to be undertaken by non-state actors. Moreover, CSR has positive associations with networking and brokerage roles; therefore, this study reveals the utility of various voluntary policy instruments.

This study demonstrates the role of governmental initiation and its influence on non-state actors, even for voluntary environmental tools. The CSR initiatives of private actors can also be supported and encouraged by the government, which will promote participation by private actors in voluntary collaborative networks and their leading role as network facilitators.

By understanding the positions and roles of each actor in the environmental collaborative networks, environmental policymakers can better understand the possibilities and the capabilities of each actor both to improve policy design and learning and to respond to policy changes effectively.

Voluntary collaboration and CSR are non-regulated policy tools; however, they can be promoted and introduced into society by governmental organizations, and they affect each other.

Despite the importance of brokers in creative projects, limited attention has been devoted to the micro-interactions by which brokers induce others’ collaboration while simultaneously retaining some control over creative production. Building on an interactionist perspective, we develop the concept of brokerage style – i.e., a recognizable pattern in the ways in which a broker interacts with others. By using different brokerage styles in different phases of a creative project, brokers can orient the social interactions among project participants, “charging” those interactions with different types of emotional energy and mutual attention, eventually inducing collective collaboration and limiting participants’ expectations of control. We illustrate our interactionist model of brokerage styles with examples from the music and TV industries.
