Collaboration Networks, Structural Holes, And Innovation: A Longitudinal Study

To assess the effects of a firm's network of relations on innovation, this paper elaborates a theoretical framework that relates three aspects of a firm's ego network-direct ties, indirect ties, and structural holes (disconnections between a firm's partners)-to the firm's subsequent innovation output. It posits that direct and indirect ties both have a positive impact on innovation but that the impact of indirect ties is moderated by the number of a firm's direct ties. Structural holes are proposed to have both positive and negative influences on subsequent innovation. Results from a longitudinal study of firms in the international chemicals industry indicate support for the predictions on direct and indirect ties, but in the interfirm collaboration network, increasing structural holes has a negative effect on innovation. Among the implications for interorganizational network theory is that the optimal structure of interfirm networks depends on the objectives of the network members.Managemen

Understanding Small Business Networking and ICTs: Exploring Face-to-Face and ICT-related opportunity creation mediated by Social Capital in East of England Micro-businesses

Small businesses that are sole traders or micro-businesses—with few, if any employees notoriously suffer from a ‘liability of smallness’ (Aldrich and Auster 1986), including poor access to various resources. However, many authors argue that the inherent problems of smallness can be overcome with networking and good network connections. Resources, the opportunities to access them and other benefits apparent from networks and networking are readily apparent in the literature. However, few articles, if any, have examined small business networking from the perspective of this study—using in-depth qualitative methods, the theoretical construct of social capital and exploring the increasing role of Information and Communication Technologies (ICTs) in networks and networking—as part of understanding a variety of entrepreneurial opportunities. This article provides much needed empirical insights on how and if ICTs support opportunity creation amongst small businesses within a spatial and social network perspective. Its ‘media ecology’ approach does not over-prioritise the role of ICTs, but instead examines their interrelationships with face-to-face contact—putting technology in its ‘place’. The article focuses on the notion of ‘opportunity creation’ from networks, since this is the outcome critical for the small businesses themselves in order to generate economic benefits for their business. It seeks to provide a higher level, outcomebased framework that helps specify the various sorts of opportunities created by networks for small businesses, based on original ethnographic material and findings from a case study of East of England micro-businesses

Internet Entrepreneurship: Networks and Performance of Internet Ventures In China

This article examines the contingent value of entrepreneurs' networks to survival likelihood of Internet ventures, and the dynamics of entrepreneurs' networks over time. The empirical data are composed of the longitudinal surveys of 94 Internet ventures in Beijing, China. The study found the positive and the negative contingent effects of structural holes on the survival likelihood of new firms. The study found that networking skills of entrepreneurs are associated positively with the changes in networks over time. Improved social skills lead to greater firm legitimacy.http://deepblue.lib.umich.edu/bitstream/2027.42/40139/3/wp753.pd

Inferring Social Status and Rich Club Effects in Enterprise Communication Networks

Social status, defined as the relative rank or position that an individual holds in a social hierarchy, is known to be among the most important motivating forces in social behaviors. In this paper, we consider the notion of status from the perspective of a position or title held by a person in an enterprise. We study the intersection of social status and social networks in an enterprise. We study whether enterprise communication logs can help reveal how social interactions and individual status manifest themselves in social networks. To that end, we use two enterprise datasets with three communication channels --- voice call, short message, and email --- to demonstrate the social-behavioral differences among individuals with different status. We have several interesting findings and based on these findings we also develop a model to predict social status. On the individual level, high-status individuals are more likely to be spanned as structural holes by linking to people in parts of the enterprise networks that are otherwise not well connected to one another. On the community level, the principle of homophily, social balance and clique theory generally indicate a "rich club" maintained by high-status individuals, in the sense that this community is much more connected, balanced and dense. Our model can predict social status of individuals with 93% accuracy.Comment: 13 pages, 4 figure

What makes a gatekeeper? Insights from the Finnish nano-community

In the process of transferring scientific knowledge to industry the role of individual academics has received less attention than the other actors in this process. This paper aims to identify the characteristics of these key individuals, or gatekeepers, by analysing them within the context of technology transfer in a science and technology community. The estimation results show that individuals who are able to provide firms with relevant research information and results are connected to the firms informally and formally. They have commercial motivations in their research and are more likely to act as gatekeepers in social networks. On the other hand, some of the a priori assumptions of these characteristics fail to have significant influence.Technology transfer, nanotechnology, social networks, gatekeepers
