Abstract:Constructing innovation networks and cultivating innovation corridors are important to realize regional innovation development. Based on the data of patent transfer from 1987 to 2018, this paper analyzes the spatial-temporal evolution of technology transfer network at different scales in the Yellow River Basin, and proposes the cultivation path of Zhengzhou-Luoyang-Xi’an innovation corridor. Firstly, it is found that a majority of technology transfer within the basin is switching from inter-provincial transfer to intra-provincial transfer, with provincial capitals being the main source of technology. Xi’an is the primary source of technology transfer network, and cities, such as Zhengzhou, Qingdao, and Jinan, are secondary sources. Moreover, the technology sources outside the Yellow River Basin are mainly located in the Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta and other developed urban agglomerations. In addition, Xi’an, Jinan, Qingdao and other high-level central cities have become the main receiving areas of technology transfer. This study concludes that the construction of inter-provincial innovation network should focus on the construction of Zhengzhou-Luoyang-Xi’an innovation corridor, in order to realize the matching and coordination of industrial technological advantages and technological demands of different cities, promote the construction of Zhengzhou-Luoyang-Xi’an high-quality development cooperation belt, and then accelerate the innovation-driven development process of the Yellow River Basin.
