The ties that lead: A social network approach to leadership

This article investigates, for leadership research, the implications of new directions in social network theory that emphasize networks as both cognitive structures in the minds of organizational members and opportunity structures that facilitate and constrain action. We introduce the four core ideas at the heart of the network research program: the importance of relations, actors' embeddedness, the social utility of connections, and the structural patterning of social life. Then we present a theoretical model of how network cognitions in the minds of leaders affect three types of networks: the direct ties surrounding leaders, the pattern of direct and indirect ties within which leaders are embedded in the whole organization and the interorganizational linkages formed by leaders as representatives of organizations. We suggest that these patterns of ties can contribute to leader effectiveness.     

Strategy implementation and organizational change: How formal reorganization affects professional networks

Strategy implementation is difficult, particularly as it often requires changes in formal organization structures. Prior research has shown that change in the formal structure may affect employee networks. Yet, we know relatively little about how such changes affect different network ties. This paper considers how formal structural change affects senior managers’ ability to maintain their intraorganizational networks. The hypotheses are tested on sample of 884 work-related relationships of 96 partners in a global professional services firm. This firm had recently implemented a new strategy, which led to a change in the product-market focus and the resulting formal structure. Our findings reveal that the characteristics of a specific network tie determine whether it is affected by formal structural change. In particular, we find that network ties that are highly embedded in the social structure are more likely to be affected by change in the formal structure. In contrast, ties that are relationally embedded are less likely to be affected by change in the formal structure. We discuss the theoretical and practical implications of these results. In particular, the findings may have consequences for the success of strategy implementation and strategic transformation efforts.     

跨国专利合作网络中技术接近性的调节作用研究

技术接近性对于企业间的跨国专利合作具有重要作用.基于多维接近性整体分析框架,采用中国电力系统技术领域2000年至2008年国外专利合作数据,分析技术接近性对其他接近性的调节作用.通过构造112家中外企业的专利合作网络,运用QAP网络回归方法实证检验跨国专利合作网络中技术接近性在地理接近性和社会接近性影响专利合作网络中节点连接距离和连接重要性过程中的调节作用.研究结果表明,在考虑多维接近性共同作用时,技术接近性对网络节点的连接距离和连接重要性具有重要影响,有助于节点之间构筑较短的连接渠道并形成较为重要的合作关系.除此以外,技术接近性还能正向调节社会接近性对连接重要性的正效应,但对于社会接近性与连接距离之间的关系没有显著的影响.由此验证了技术接近性可以影响其他接近性与跨国知识合作关系的基本假设,为进一步揭示不同接近性之间的相互作用机制提供了理论基础.     

Distribution Channel Network and Relational Performance: The Intervening Mechanism of Adaptive Distribution Flexibility

Network theories argue that organizations can enjoy information and control benefits from the network in which they are embedded. Focusing on distribution channel networks with strong, prominent, and central ties, this article argues that distribution flexibility, composed of logistics and relationship flexibility, is a response to environmental uncertainty that mediates the effect of channel network embeddedness on relationship performance. Results show that logistics flexibility and relationship flexibility fully mediate the effect of channel network embeddedness on relationship satisfaction, but that only relationship flexibility mediates the effect of channel network embeddedness on long‐term relationship orientation. Furthermore, not only is the effect of tie strength on logistics flexibility stronger in an uncertain environment, but relationship flexibility also decreases as the congruence between uncertainty and tie strength increases, suggesting a complex higher‐order contingency model.     

The Role of Interorganizational and Organizational Factors on the Decision Mode for Adoption of Interorganizational Systems*

The dramatic growth of interorganizational systems (IOS) has changed the way organizations conduct their business, and has resulted in significant tangible and intangible benefits being realized by participating firms. However, the implementation of these IOS requires the cooperation and commitment of all the participating members. These members may have complex economic and business relationships among themselves that can result in a number of social, political, and economic factors influencing the adoption and implementation of IOS. This study examines the role of interorganizational and organizational factors on the decision mode for adoption of IOS, in the specific context of electronic data interchange (EDI). Four interorganizational factors, based on the socio-political framework derived from research in marketing, and five organizational factors based on research in IS were used in the study. The data for the study were collected through a large scale field survey. Two respondents, the sales/purchase manager and the IS manager, from 201 firms responded to the survey. The results of discriminant analysis of the data reveal that two interorganizational variables, competitive pressure and exercised power, and two organizational variables, internal need and top management support, are important variables to differentiate firms with proactive decision mode from firms with reactive decision mode. The study also evaluates the differences between proactive and reactive firms on three implementation outcomes. Proactive firms are found to have greater extent of adaptation, more external connectivity with trading partners, and better integration of EDI information in their internal IS applications.     

The impact of supply chain management practices on competitive advantage and organizational performance

Effective supply chain management (SCM) has become a potentially valuable way of securing competitive advantage and improving organizational performance since competition is no longer between organizations, but among supply chains. This research conceptualizes and develops five dimensions of SCM practice (strategic supplier partnership, customer relationship, level of information sharing, quality of information sharing, and postponement) and tests the relationships between SCM practices, competitive advantage, and organizational performance. Data for the study were collected from 196 organizations and the relationships proposed in the framework were tested using structural equation modeling. The results indicate that higher levels of SCM practice can lead to enhanced competitive advantage and improved organizational performance. Also, competitive advantage can have a direct, positive impact on organizational performance.     

Supported,detached, or marginalized? The ambivalent role of social capital on stress at work

Relationships with work colleagues can mitigate job stress; this article proposes a new perspective on such effects, in accordance with social capital theory, to delineate the potentially distinct impacts of the two dimensions of relational and structural social capital. A partial least squares analysis of network data in a medium-sized company (N = 343) offers evidence of an effect of the relational dimension (tie strength), through social support. The structural dimension (bridging ties, i.e. whether an employee has social ties with members of other departments) reveals a dual effect involving reduced stress but also diminished social support, which can increase stress. These dual effects reflect the two levels on which bridging ties act, namely, cognitive (selfdistancing) and social (marginalization from the immediate work context) levels. Next, with two scenario-based experiments (N = 289 and 245), the authors manipulate bridging ties and gain further evidence of the proposed mechanisms. These findings highlight the social underpinnings of stress and the critical role of the structure, not just the quality, of work relationships. They also identify a dark side of bridging ties, which can enhance individual performance but also create the potential for negative wellbeing outcomes.     

The roles of supply network centralities in firm performance and the moderating effects of reputation and export-orientation

Abstract

This study explores how supply network degree, closeness, and betweenness centralities affect firm performance, and the moderating effects of organizational reputation (measured by PageRank centrality) and export-orientation. The supply chain relationship empirical data are drawn from manufacturing and manufacturing service companies in Hong Kong, China. Social network analysis and moderated regression analysis were adopted to test the hypotheses for a sample of 814 focal firms with 3086 supply chain ties. The results indicate that in-degree and closeness centralities improve firm performance. Reputation is found to positively moderate the relationship between closeness and sales performance, but negatively moderates the relationship between betweenness and sales performance. Export-orientation has no effect on relationships. This study contributes to the literature by providing additional empirical evidence on the role of supply network position in firm performance. It also introduces PageRank centrality as a new measure of organizational reputation in a supply network.     

Competitive and Cooperative Positioning in Supply Chain Logistics Relationships*

Cooperative logistics relationships require the sharing of information, which must be enabled by the integration of disparate information systems across partners. In this article, we theorize business‐to‐business logistics relationships should be managed using cooperative and competitive postures. Based on data from 91 dyadic relationships using interorganizational information technology (IT), we find that performance gains accrue when parties share strategic information and customize IT; mutual trust enables IT customization and strategic‐information flows and equitable relationship‐specific investments positively impact IT customization, mutual trust, and performance. Among other scholarly and practical implications discussed, partners should compete on resources for IT customization and cooperate to share strategic information. Managers tend to think of relationships with firms as polar opposites and view them as entirely cooperative or entirely competitive. Our results support active balancing and understanding of both competitive and cooperative stances. Such an approach enables conditions for participation symmetry that yields greater performance gains.     

I need you,but do I love you? Strong ties and innovation in supplier–customer relations

Research on supplier–customer relationships has attracted a great deal of attention, as such relationships can positively impact firms’ knowledge acquisition and innovation. Within this stream of research, strong ties with customers have been explored with attention to their beneficial and detrimental effects, presenting a paradox to be addressed. To contribute to this debate, we suggest focusing on how tie strength is measured, and accordingly, we return to the seminal definition of tie strength by Granovetter (1973), who defines it as a combination of behavioural and affective components. We acknowledge that the two components have different characteristics and dynamics, which urges us to unbundle the two components and measure their separate impacts on knowledge acquisition and innovation. To further investigate the role of tie strength in innovation, we hypothesize and test the mediating role of knowledge acquisition. We test our hypothesis in vertical partnerships between small- and medium-sized enterprises (SMEs) located in a high-tech cluster and their key customers. We show that the unbundled components of strong ties have a direct positive impact on the knowledge acquisition of high-tech SMEs and an indirect positive impact on innovation, with knowledge acquisition mediating the effect. Our study contributes to the debate on the paradox of tie strength in supplier–customer relations by providing and empirically testing a research approach that might complement the previous approaches and by shedding light on the important role of the affective component of tie strength in knowledge acquisition and innovation.

Knowledge ties among subsidiaries in MNCs: A multi-level conceptual model

While ties among subsidiaries—the key players of a MNC network—are a prerequisite for the formation of the network and the flow of knowledge within the organization, we know little about factors influencing the formation of such ties. By building on the literature on inter-firm networks and knowledge-based view of the firm, we develop a multi-level model consisting of subsidiary characteristics, dyadic dynamics, and salient contextual factors to explain the inter-subsidiary collaboration for knowledge development and exchange. We bring to the fore the importance of examining multiple dimensions in understanding what predicts tie formation and the efficacy of these ties in creating a knowledge advantage. This paper advances the notion of subsidiary knowledge networking capability—the ability to form, manage, and leverage a network for gaining and sharing knowledge—and suggests that such capability is critical for subsidiaries and by extension the MNC, to achieve a competitive advantage.

关系强度、关系资源与新企业绩效——基于行为视角的实证研究

大多数研究认为,善于利用社会关系网络的创业者更可能收获更高的新企业绩效,但对关系资源在促进新企业绩效中的角色并没有引起足够重视.针对这一问题,本文考察了创业者所利用的关系强度、关系资源与新企业绩效之间的逻辑联系,以及资源获取行为对该作用过程的中介作用.研究发现:在创业过程中,越丰富利用关系资源的创业者更容易整合到更丰裕的创业资源,从而提升新企业绩效.尽管所利用关系强度更高的创业者往往能以更快的速度获取创业资源,但并不能确保创业者能够迅速应付创业初期的资源需求,并不会改善新企业绩效.本文的主要理论贡献在于嵌入到行为层面揭示了社会资本改善新企业绩效的作用机制及资源获取的中介作用,发现网络嵌入性资源是有助于解释新企业绩效差异的重要变量,这是对已有文献的重要补充.     

Inside Out? Organizational Membership,Ambiguity and the Ambivalent Identity of the Internal Consultant

Changes in organizational structure, roles and technologies have led to an increasing appreciation of the complexities of organizational membership. While a growing literature has focused on this issue with regard to precarious and marginal employees, this paper explores how senior and middle managers in ambiguous roles make sense of their work identity and organizational membership. Based on extensive interviews with human resource and organizational development managers operating as 'internal consultants', it is argued that managers in such ambiguous roles seek to develop a preferred identity which balances both organizationally distinctive and inclusive elements. While potentially conflicting, this ambivalent position can also be a source of strength and differentiation, involving claims to structural autonomy and specialist expertise, aligned to an intimate understanding of organizational politics and personalities. Through analysis of the interview data, the paper highlights the boundary dimensions around which managers in internal consulting roles develop such an ambivalent organizational identification, the ways in which distinctive and inclusive aspects of identity are rationalized, and the constraints upon the achievement of a preferred identity as an internal consultant.     

Rich Ties and Innovative Knowledge Transfer within a Firm

We show that contacts in formal, informal and especially multiplex networks explain transfer of innovative knowledge in an organization. The contribution of informal contacts has been much acknowledged, while that of formal contacts did not receive much attention in the literature in recent decades. No study thus far has included both these different kinds of contacts in a firm, let alone considered their combined effect. The exact overlap between formal as well as informal contacts between individuals, forming multiplex or what we call rich ties because of their contribution, especially drives the transfer of new, innovative knowledge in a firm. Studying two cases in very different settings suggests these rich ties have a particularly strong effect on knowledge transfer in an organization, even when controlling for the strength of ties. Some of the effects on knowledge transfer in an organization previously ascribed to either the formal network or the informal network may actually be due to their combined effect in a rich tie.     

Power imbalance and value creation in joint ventures

Joint ventures (JVs) often do not create expected value due to power imbalance between partners. Despite the fact that JV partners are embedded in relational constraints, prior research has largely relied on economic reasoning by focusing on equity ownership difference between JV partners as the main source of power imbalance. We extend prior research to also consider important relational factors represented by repeated ties between partners and network openness, as well as institutional status difference and network status difference as two additional dimensions of power imbalance. Our findings indicate that ownership power imbalance by itself does not have a significant effect on value creation. However, value creation is facilitated when there is ownership power imbalance between partners with more repeated ties. In contrast, value creation may be hindered when JV partners with unequal ownership are embedded in more open interfirm alliance networks. Furthermore, value creation is facilitated if JV partners that have unequal ownership also have network status power imbalance in the same direction.     

Social ties, task-related communication and first job performance of young engineers

This study investigated the relationships among social ties, task-related communication, and first industrial job performance of a group of young engineers by utilizing a cooperative (coop) engineering program as a natural study. The coop arrangement allowed the researcher to examine the work behavior of these young engineers with similar academic training who were working on comparable work assignments in the same set of organizations.The study found that the job performance of the coop engineers was related to the pattern of work- related communication but not the total number of contacts. Specifically, high performance new engineers were integrated more broadly into the interpersonal communication networks than low performance new engineers. Moreover, high performance new engineers exhibited communication patterns similar to those of high performance veteran engineers working on similar types of technical work. Social ties with the company staff was found to be related positively with job performance, but social ties with other coop engineers was found to be related negatively with job performance, a result which challenges an implicit assumption often made by researchers and managers about the organizational socialization of newcomers. Overall, this study provides an integrative framework for relating social ties and communication as key factors for understanding the job performance of young engineers and presents a methodology for assessing their organizational assimilation.     

Interorganizational Governance Value Creation: Coordinating for Information Visibility and Flexibility in Supply Chains*

More thoroughly understanding how interorganizational governance value can be created by information technology and other governance mechanisms is critical for supply chain management. Based primarily on transaction‐cost economics and supplemented by the resource‐based view, this study investigates how interorganizational governance (i.e., relational governance and virtual integration) can create value (i.e., information visibility and supply chain flexibility) in the supply chain context. The findings show that both relational governance and virtual integration benefit information visibility. Those results also support both direct and indirect (via information visibility) effects of relational governance on supply chain flexibility. Although failing to affect supply chain flexibility directly, virtual integration can still improve supply chain flexibility with its ability to enhance information visibility. Thus, interorganizational governance mechanisms emphasizing both control and collaboration can influence the gain from collaboration‐specific capabilities, leading to the competitive advantage of a supply chain. The results of the study suggest that firms can gain greater supply chain flexibility within existing interfirm relationships by enhancing information visibility through virtual integration and relational governance.
