Spatial-temporal Pattern and Mechanism of the Coupling Coordination Relationship Between Digital Economy and Urban-rural Integration Development at Prefectural level in the Yangtze River Economic Belt
Based on the panel data of 108 prefecture-level cities in the Yangtze River Economic Belt from 2011 to 2020,this study applies the coupling coordination degree and PVAR model to analyze and explore the coupling coordination relationship between digital economy and urban-rural integration development.The results show that:1)The relationship between digital economy and urban-rural integration development basically realized the transformation from mildly dysfunctional to basically coordinated in 108 prefectural-level cities of the Yangtze River Economic Belt from 2011 to 2020,among which the digital economy and urban-rural integration development of provincial capital cities always maintain a high degree of coupling coordination and have a strong radiation-driven effect on the neighboring prefecture-level cities.2)In terms of the coupling coordination degree between digital economy and urban-rural integration development in different regions,cities in the lower reaches of the Yangtze River are higher than that in the upper reaches of the Yangtze River,followed by cities in the middle reaches of the Yangtze River.Among them,cities in the lower reaches of the Yangtze River have been in the lead for a long time,cities in the middle and upper reaches of the Yangtze River were basically comparable in 2011-2016,but cities in the upper reaches of the Yangtze River have been significantly higher than that in the middle reaches of the Yangtze River since 2017.3)At present,it has not formed a long-term positive interactive relationship between digital economy and urban-rural integration development in prefecture-level cities of the Yangtze River Economic Belt.Specifically,the development of urban-rural integration promotes the growth of the digital economy,while there is obvious regional heterogeneity in the role of the digital economy on the development of urban-rural integration.Among them,it has a short-term promotion effect on the urban-rural integration development in prefecture-level cities of the upper and lower reaches of the Yangtze River,but has a certain negative impact on the urban-rural integration development in prefecture-level cities of the middle reaches of the Yangtze River.Therefore,in order to realize the optimal solution of digital economy and urban-rural integration development,underdeveloped prefecture-level cities in the upper reaches of the Yangtze River should focus on development issues and enhance the economic development momentum.The prefecture-level cities in the middle reaches of the Yangtze River should make up for the short boards of development and create the growth poles of digital economy development.The developed prefecture-level cities in the lower reaches of the Yangtze River should focus on the issue of regional coordination,and coordinate the promotion of the regional digital economy development.
