摘　　要：完善现代社会信用体系是优化营商环境、推进中国式现代化的重要保障。运用Dagum基尼系数及其子群分解法,对选取的中国285个地级市2010—2021年信用发展水平的空间非均衡程度及其来源进行定量刻画。研究发现:285个地级市信用环境仍有较大完善空间,信用环境指数在地理空间上呈现集聚特征,具有显著空间分异和空间依赖性。实施差异化外部政策,发挥资源禀赋和比较优势,推动区域信用环境水平均衡发展,是完善现代社会信用体系的必然要求,是优化营商环境的重中之重。Improving the modern social credit system is an important guarantee for optimizing the business environment and promoting the Chinese path to modernization.Using Dagum Gini coefficient and its subgroup decomposition method,this paper quantitatively describes the degree and source of spatial disequilibrium of credit development level in the selected 285 prefecture-level cities in China during 2010-2021.The results show that the credit environment of 285 prefecture-level cities still has a large room for improvement,and the credit environment index presents a agglomeration feature in geographical space,with significant spatial differentiation and spatial dependence.Implementing differentiated external policies,giving full play to resource endowments and comparative advantages,and promoting the balanced development of regional credit environment are inevitable requirements for improving the modern social credit system,and are the top priority for optimizing the business environment.
