Does Regional Market Integration Enhance Urban Green Development Efficiency?——Empirical Analysis Based on the Unified Large Market in the Yangtze River Delta
Regional market integration facilitates the effective role of the market and proactive government support for promoting coordinated urban green development.Using the DEA model based on the overall production frontier and non-radial direction distance function,this study calculates the total factor green development efficiency of 41 cities in the Yangtze River Delta.The results show that the total factor green development efficiency of Yangtze River Delta cities is increasing.Specifically,central area cities show a rapid and sustained increase in total factor green development efficiency,while peripheral area cities experience a trend of initial decrease,followed by a plateau,and then rapid increase in total factor green development efficiency.Empirical research using the panel Tobit model examines the effects of commodity market integration,capital market integration,and labor market integration on urban total factor green development efficiency.The results indicate that market integration in the Yangtze River Delta generally promotes improvements in urban total factor green development efficiency.Specifically,capital market integration significantly facilitates the enhancement of urban total factor green development efficiency.However,the overall promoting effects of commodity market integration and labor market integration are not yet significant on urban total factor green development efficiency.The impact of market integration on total factor green development efficiency is more pronounced in central area cities of the Yangtze River Delta.It is necessary to further leverage the dominant role of market mechanisms and realize the organic combination of effective markets and promising governments to enhance the promoting effect of market integration on urban green development efficiency in the Yangtze River Delta.Specifically,there is a need to strengthen the positive role of commodity market integration and labor market integration in promoting urban total factor green development efficiency,and to enhance the promoting effect of market integration on improving total factor green development efficiency in the peripheral area cities of the Yangtze River Delta.
