“…Polanyi [83] argued that knowledge is embedded in inventors who reside in a city. Figure 1 shows the framework of inter-city networks of co-invention and the social networks of inventors [25]. The upper framework refers to a co-inventive region within city A to F, while all nodes from its social network counterpart signify the individual inventors who reside in these cities.…”

“…In contrast, if the same neighbors compose a co-inventive core in a spatial LISA cluster map, co-patenting relationships of inventors are explained by spatial proximity. Moreover, the network LISA cluster map should appear for co-inventive core cities that are spatially scattered, as inter-city relationships often support co-patenting by inventors residing in dispersed cities [25,90]. A majority of low co-inventive islands occurring in the network LISA cluster map is assumed to be common because few national centers exist and most cities' linkages are confined to the regional nexus [11,16,90].…”

“…Owing to the wide variation in geographical spacing and the 'island' characteristic, this article uses the number of nearest neighbors (also known as an area's k value) as the most appropriate choice to identify neighboring structures in the contiguous U.S. cities [24,25,90]. Numbers of cities ranging from three to 20 are considered to determine the appropriate number of nearest cities.…”

“…I follow Ó hUallacháin and Lee [24], Lee [25], Hall et al [91], Cortright and Mayer [92], and Hevesi and Bleiwas [93] by selecting the 3-digit classes (424, 435, 514, and 800) into the sub-category of biotechnology. Class 435 covers chemical groupings and includes molecular biology and microbiology inventions.…”

Knowledge creation involves social and collaborative processes with local and extra-local partners. The space of knowledge flows functions as a system of networks where knowledge is transmitted around different alignments of agents in distant places. Scholars argue that the concept of urban resilience combines local and extra-local competencies to develop an inter-city system, this is a major strategy for cities to mitigate and adapt to climate change and economic recession. Little attention has been given to the role of networks in co-invention and few empirical studies have been conducted. This article provides insights into the structure of inter-city networks of co-invention by examining the relative importance of the network compared with spatial proximity in biotechnology co-patenting across 150 American cities from 1983 to 2013. Results show that the U.S. inter-city structure gradually becomes more explicit, apparent, and identifiable in the network-based system. Network proximity better defines the biotechnology co-patenting relationships among the U.S. cities compared with spatial proximity. The current inter-city networks of co-invention are mostly regional, with some national but few local ties. This structure provides a way to develop mitigation and adaptation policies for climate disasters or economic recessions.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
