How does infrastructure within national innovation systems spur innovation diffusion? Using the expansion of high-speed railways (HSR) in China as a quasi-experimental design, we theorize that connection to the HSR networks will facilitate the engagement in technology licensing, one typical example of innovation diffusion, by decreasing information asymmetry and accessing to a large market with complementary technologies. We further clarify potential mechanisms beyond of focal relationship by introducing three boundary conditions. We use 251 city samples in China between 2005 and 2015 to test our theory. We find evidence that cities’ technical licenses have been increased after the connection to the HSR. We also find that such a positive relationship is stronger when a local city has more human capital and greater foreign competition. Our finding contributes to economic geography literature and research on transport infrastructure by shedding new insights on the interplay between HSR and regional knowledge diffusion.

In spite of the great importance of science in generating valuable innovations the exploitation of scientific discoveries, even within a firm, is a complex process and only a small fraction of a firm’s scientific discoveries is further taken-up in technology development. This study provides evidence that even though firms are active producers of valuable scientific discoveries, the exploitation of internal science in a firm’s technology development is not straightforward. I investigate the role of the geographical distribution of a firm’s science and technology activities. The results show that firms are better able to exploit internal scientific research in technology domains where science and technology activities are geographically co-located.

We develop a typology of regional innovation networks based on the extent to which the inventors in a given location span structural holes within the internal collaboration network or connect local inventors with inventors outside their region. We identify four types of network configurations characterized by different levels of internal brokerage and external boundary-spanning (fortresses, multi-level brokers, playing fields and absorbers). Using data on co-inventing networks within and between United States Metropolitan Statistical Areas between 2000 and 2014, we show that configurations balancing internal brokerage (closure) and low (high) external boundary-spanning lead to higher innovation performance than isomorphic configurations. In a nutshell, our findings convey a more nuanced, multi-level understanding of the trade-offs between different brokerage roles in regional innovation dynamics.

This paper explores patterns of both managerial and technological innovations, how they interact, and their relationship with firm performance. Parallels between managerial innovations and investments in intangibles are highlighted. Using a data set relating to 1497 UK enterprises in 2009 with a special emphasis upon non-manufacturing, it is shown that firms both source and use technological and managerial innovations and different types thereof simultaneously, suggesting widespread complementarities across innovations. Factor analysis is used to generate combined indicators of firms’ overall efforts in both sourcing and using different innovations and enables their allocation to clusters. The most active sourcing and using clusters are the smallest, whilst the least active sourcing and using clusters are the largest. Firm characteristics differ across both sourcing and using clusters in expected ways. Further, (i) there is a positive relationship between corporate performance and the intensity of both sourcing and using innovations, and (ii) firms undertaking technological (managerial) innovation experience greater improvement in sales growth if they also undertake managerial (technological) innovation. The findings indicate that reliance upon either technological or managerial indicators of innovation alone could be misleading in terms of both the extent of innovation and the impacts of different types of innovation upon firm performance. policy implications are drawn.
