Structure and influencing factors of urban new quality productive function network in China:A case study of strategic emerging industries
Based on the background of the formation of new quality productivity,this study took intelligent manufacturing,biomedicine,and green environmental protection industry in strategic emerging industries as examples,constructed new quality productive function networks by using enterprise foreign investment data up to 2023,and applied the social network analysis method to examine the spatial structure characteristics and influencing factors of urban new quality productive function networks in China.The findings are as follows:1)Compared with previous urban network studies,the networks of new quality productive function do not show a"diamond structure",and the medium and high intensity network links are radiation-type spatial connections with Beijing at the core.2)The results of influencing factor analysis show that provincial boundaries have a negative impact on all three kinds of networks,but the negative effect of spatial distance does not occur in the intelligent manufacturing network.Due to the construction of major regional high-speed transportation infrastructure in China,the impact of spatial distance on intercity investment in new quality productive function networks is relatively weak.However,administrative barriers and the hindrance effect of provincial boundaries still play a significant role.3)The study distinguished the impact of socioeconomic-related variables on the spatial structure of urban networks in the cities where investments are sent and the cities where investments are received,and found that the impact of different variables in these networks are significantly different,reflecting the differences in the development of different industries,especially in the spatial choice behavior of foreign investment.This study revealed the changing characteristics of China's urban network spatial structure in the context of the formation of new quality productivity,which has academic significance for improving the scientific understanding of the general law of the evolution of spatial structure of China's urban system in the context of new development.Empirical cases enrich the research topics of new quality productivity.This study provides a research perspective for urban geography to actively respond to the major strategic needs of national development and the main battlefield of service economy.
