Abstract
Recently, the Chinese government decided to support the integrated development of the Yangtze River Delta (YRD) in a national strategic way. On this background, this paper investigates the regional integration in the technology transfer system of the YRD based on patent transfer from three levels: overall, technology supply chain, and technology sales chain. It also uses the modularity maximization method to detect the community structure of the inter-city patent transfer network in China. The results show that regional integration of the technology transfer system of the YRD at both overall level and technology supply chain level had not been realized up to 2015, but had been achieved at the technical sales chain level. Technology flow in the YRD was increasingly moving across the border, and the intra-region technology transfer network was increasingly unable to meet the needs of technological development of the cities in the YRD. This paper has several limitations concerning the representativeness of patent data, the manifestation of patent data in technological transfer and international comparison.
Highlights
Regional integration is increasingly regarded as a tool for reaping the benefits and countering the negative impacts of globalization
China’s inter-city patent transfer network was divided into 14 communities, of which the largest had 49 cities and the smallest only consisted of 2 cities. 24 cities of the Yangtze River Delta (YRD) at this period were assigned to 7 communities
9 communities were detected in China’s inter-city patent transfer network, of which the largest had 101 cities and the smallest consisted of 9 cities. 26 cities of the YRD at this period were divided into 7 communities
Summary
Regional integration is increasingly regarded as a tool for reaping the benefits and countering the negative impacts of globalization. Regional integration has been used by the Chinese government both at the national and local level as a main policy tool to deal with the development gap within specific region [15,17,18]. There has been a significant increase in the literature documenting the regional integration in China in recent years, within which the YRD is an important example [19,20,21,22]. At the just-concluded China First International Import Expo, Chinese President Xi Jinping pointed out that the Chinese government decided to support the integrated development of the YRD in a national strategic way. Few attentions have been paid to discover the regional integration from the perspective of technology flows
