Estimation and Spatial Differentiation of China's Urban Green Business Environment Index under Carbon Neutrality
Under the background of carbon neutrality,building a green business environment in cities has become an important guarantee to promote high-quality economic development,and a comprehensive and accurate measurement of the green business environment in cities is the key.Using panel data of 283 prefecture-level cities in China from 2008 to 2018,based on the composite ecosystem theory,this paper constructs an evaluation system for China's urban green business environment.Furthermore,by con-structing the optimal combination weights of entropy weight method,CRITIC method and coefficient of variation method,the ur-ban green business environment index is estimated.Meanwhile,the spatial differences of urban green business environment and their sources are investigated by using Theil index.The results show that:①Although the green business environment of Chinese cities is constantly optimized(0.0733→0.1543),there are significant regional differences,among which the relative advantages of green business environment of eastern cities are obvious and expanding.② Green business environment situation of each subentry index score also increased,and there is also significant regional differences,the eastern region in the financial environment,market environment and holds an absolute advantage in human resources,the central and western regions environment of public service and rule of law is constantly improved,and the index of urban ecological environment as a whole are relatively low.③ The Theil index of green business environment showed a downward trend(0.3565→0.3482),indicating that the regional imbalance of green business environment in Chinese cities began to be alleviated,and this imbalance mainly came from the differences within provinc-es.The green business environment index calculated in this paper provides a new perspective and basis for the optimization of ur-ban business environment.Based on the above conclusions,this paper puts forward policy implications from the following two as-pects:① All localities should focus on improving the level of indicators of green business environment.② Promote coordinated development between and within regions in a targeted way.
