摘要：基于张三保等(2023)对中国内地省份营商环境的评估,本研究进一步构建出中国内地城市营商环境评估指标体系，涵盖4项一级指标、14项二级指标及23项三级指标。运用最新可获取的数据，量化评估中国内地296个地级及以上层级城市2017—2022年的营商环境，并对不同范围城市(省会、副省级、一线、新一线、二线、超大、特大城市)营商环境的6年均值进行局部比较。结果显示，评估期间中国城市营商环境整体向好，但不同城市群存在显著差异。其中，一线城市营商环境以高水平和高均衡度持续领先；副省级城市和省会城市整体稳健，且东西部之间差距大；新一线城市发展策略差异化较大，5个城市均衡发展，5个城市单项突出；二线城市的沿海城市市场活力突出，内陆城市法治环境较好；超大城市规模优势下各子环境均领先，尤其是市场环境；特大城市区域辐射能力强，但均衡度需提升。在此基础上，本研究为中国城市营商环境的持续优化提供了政策建议和未来研究方向，为各城市找准定位、确定标杆提供了重要参考，同时也为学界开展宏微观结合研究提供了数据支持。

Abstract: Based on the assessment of the business environment in Chinese mainland provinces conducted by Zhang et al.(2023), this study further constructed an evaluation index system for the business environment of Chinese mainland cities, covering four first-level indicators, 14 second-level indicators, and 23 third-level indicators.Using the latest available data, this study quantitatively evaluated the business environment of 296 prefecture-level and above cities in Chinese mainland from 2017 to 2022, and conducted local comparisons of the six-year average business environment of different ranges of cities(provincial capitals, sub-provincial cities, first-tier cities, new first-tier cities, second-tier cities, super-large cities, and megacities).The results show that the business environment of Chinese cities has generally improved during the assessment period, but there are significant differences among different urban clusters.Among them, the business environment of first-tier cities has consistently led with high levels and high balance; sub-provincial cities and provincial capitals are overall stable, and there is a large gap between the east and west regions; the development strategies of new first-tier cities vary significantly, with five cities developing in a balanced manner and five cities having outstanding performance in individual aspects; coastal cities in second-tier cities have prominent market vitality, while inland cities have a better legal environment; megacities have led in all sub-environments under their scale advantages, especially the market environment; regional radiation capabilities of super-large cities are strong, but the balance needs to be improved.On this basis, this study provides policy suggestions and future research directions for the continuous optimization of the business environment of Chinese cities, offers important references for each city to find its position and set benchmarks, and also provides data support for the academic community to conduct combined research at the macro and micro levels.
