Regional Integration in the Inter-City Technology Transfer System of the Yangtze River Delta, China

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.

The impact of authentic leadership on individual and team creativity: a multilevel perspective

“…The YRD region, located on the east coast of China, is strategically important because it is one of the most developed urban agglomerations and considered a major engine of China's economic and urban development in the last three decades (Li and Phelps, 2019). The YRD region, which leads in terms of innovation-driven development, comprises three provinces and one municipality: Jiangsu, Zhejiang, Anhui and Shanghai (Duan et al , 2019). It is a potential source of global knowledge linkages and the most developed region in China (Wang and Shen, 2017).…”

Structural Characteristics and Spatial Patterns of the Technology Transfer Network in the Guangdong–Hong Kong–Macao Greater Bay Area

“…Shanghai seems to be both a local decentralized agency and a national hub, a more balanced broker area. Duan et al [41] discussed the structural spatial characteristics of the technology transfer network in the Yangtze River Delta from three aspects of the overall, technology supply chain, and technology sales chain, and used the block model to explore the community characteristics of China's intercity technology transfer network. Based on the patent transfer data of the State Intellectual Property Office from 2000 to 2015, Zhang et al [42] constructed China's inter-city technology transfer network, and the results showed that there was a certain geographical differentiation in China's inter-city technology transfer.…”

Development of Economic Integration in the Central Yangtze River Megaregion from the Perspective of Urban Network Evolution

“…Its spatial carriers mainly include metropolitan areas, urban agglomerations, megaregions, and other urban spatial organizations. There has been a renaissance in the regional policies and planning across China that echo national strategies and highlight inter-jurisdictional cooperation and integration [33,34]. To some extent, these practices indicate a transition in regional governance from territorial competition to regional coordination, in which adjacent municipalities are encouraged to transcend jurisdictional boundaries and function in coordinated ways as unitary megaregions.…”
