The Impact of Unified Large Market Construction on the Intercity Economic Coordinated Development
The coordinated development of intercity economy is an important direction for the construction of China's modern intercity development pattern,and the construction of a unified large market plays an important role in the process of intercity economic coordinated development.Based on a sample of 29403 pairwise cities consisting of 243 prefecture level and above cities in China from 2011 to 2020,this article empirically tests the impact,mechanism,and regulatory effect of the construc-tion of a unified large market on the coordinated development of intercity economy.The findings are as follows:the construc-tion of a unified market has significantly promoted the coordinated development of China's intercity economy,and the conclu-sion remains valid after addressing endogeneity issues and conducting robustness tests;the role of building a unified large market among cities within the same region in promoting coordinated economic development is stronger than that of cities in different regions;the construction of a unified large market can promote the coordinated development of intercity economy through the optimization of industrial structure and the driving force of market demand;Economic correlation can strengthen the promoting effect of the construction of a unified large market on the coordinated development of intercity economy,while the regulatory effect of geographical proximity is not significant.
