Spatial Structure Characteristics and Mechanism Identification of China Green Innovation Network from the Perspective of Multidimensional Proximities
Based on the application data of green invention patent cooperation in Chinese cities from 2006 to 2021,this paper constructs the green innovation network(GIN for short),analyzes its structural characteristic,reveals the driving factors that affect green innovation cooperation through geographic detector model,and uses regression discontinuity design to evaluate the promotion effect of regional coordinated strategy on green innovation cooperation.The results show that:1)The number of green invention patents and participating cities in China increased year by year,showing typical agglomeration characteristics and community distribution trend.The role and contact routes of cities in the GIN have obvious hierarchy and geographical location,provincial capitals and central cities,such as Beijing,Nanjing and Shanghai,have strong influence.The connections among these cities build the framework of GIN and lead to the formation of six green innovation communities.2)The GIN formation of China's cities is the product of the synergy and interaction of bilateral city attributes,multi-dimensional proximity and network effects.For the whole network,the network effect has the strongest influence,environment and technological proximity between cities also play an important role.3)The regional coordinated strategy is an important external force to form GIN.Strategies such as the construction of Guangdong-Hong Kong-Macao Greater Bay Area,Yangtze River Delta integration and Beijing-Tianjin-Hebei coordinated development,have significantly promoted the green innovation cooperation among cities in the region.This paper provides empirical evidence and policy enlightenment for further optimizing and perfecting the urban GIN,thus promoting high-quality development and Chinese modernization.
