营商环境与新质生产力耦合协调的时空演进及差异分析
Spatiotemporal Evolution and Difference Analysis of Coupling and Coordination between Business Environment and New Quality Productivity

选取中国30个省(市、自治区)为研究对象，以2011~2022年数据为观察样本，使用熵值法与耦合协调度模型，测算研究期营商环境与新质生产力的耦合协调发展水平，在此基础上结合Kernel密度估计和Dagum基尼系数，对比分析三大经济区域营商环境与新质生产力之间的耦合协调度的时空演进及差异分析。结果表明，中国各省市营商环境与新质生产力的耦合协调水平呈逐年上升趋势，各区域耦合协调发展水平从高到低依次为东部、中部和西部。通过高斯核函数估计得出在不同时期的地区的分别出现了协调发展水平两极分化现象，并且各省市在营商环境与新质生产力耦合协调总体水平上的区域差异不断扩大。区域间差异是造成三大经济区域耦合协调发展不平衡的主要因素，但其贡献率呈现下降趋势，同时，东部地区与西部省份之间的差距也在逐步缩小。在综合以往研究的基础上，进一步补充和丰富了营商环境与新质生产力之间的理论机制。通过耦合协调度及其空间分布特征和区域差异的综合分析，探讨了营商环境与新质生产力的关系，拓展了该领域的相关研究。分析营商环境对新质生产力发展的具体影响，并结合东部、中部和西部地区的异质性，为政策的精准投入提供了参考依据。
Taking the data from 2011 to 2022 as the observation sample, the entropy method and the coupling coordination degree model were used to measure the coupling and coordinated development level of the business environment and the new quality productivity during the study period. The results show that the coupling and coordination level of business environment and new quality productivity in various provinces and cities in China is increasing year by year, and the coupling and coordinated development level of each region is in the east, central and western regions from high to low. Through the Gaussian kernel function estimation, it is concluded that the polarization of the level of coordinated development has occurred in different regions in different periods, and the regional differences between provinces and cities in the overall level of coupling and coordination of business environment and new quality productivity have been expanding. Regional differences are the main factors causing the imbalance in the coupling and coordinated development of the three major economic regions, but their contribution rate shows a downward trend, and the gap between the eastern region and the western provinces is gradually narrowing. On the basis of the synthesis of previous researches, the theoretical mechanism between the business environment and the new quality productivity is further supplemented and enriched. Through the comprehensive analysis of coupling coordination degree and its spatial distribution characteristics and regional differences, the relationship between business environment and new quality productivity is discussed, and the relevant research in this field is expanded. This paper analyzes the specific impact of the business environment on the development of new productive forces, and combines the heterogeneity of the eastern, central and western regions to provide a reference for precise policy investment.
