| 在百年变局加速演进的关键阶段，打造国际一流营商环境既是破解“双循环”堵点的突破口，更是构筑制度竞争优势的战略支点。当前，城市群建设如火如荼，逐渐成为经济增长的新引擎，中国城市群营商环境建设已进入制度型开放新阶段，充分有效地推进资源共享和协同发展对于提升营商环境水平具有重要的现实意义。基于2011—2021年中国城市面板数据，采用多期双重差分（DID）和空间双重差分（SDID）模型，系统评估了国家级城市群建设对营商环境水平的影响效应和作用机制。结果表明：城市群建设显著提升了地区营商环境水平，且通过稳健性检验后结果依然稳健，且对地理相邻和经济结构相似城市存在空间溢出效应。异质性分析显示，非资源型城市营商环境改善效果较资源型城市改善更为明显；新兴城市营商环境提升更具弹性。机制检验发现，城市群通过规模经济、要素集聚和对外开放等路径优化营商环境。 |

| At a critical stage of accelerated transformation over the past century, creating an international first-class business environment is not only a key point to break through the "dual circulation" bottleneck, but also a strategic leverage point to build institutional competitive advantages. Currently, the construction of urban agglomerations is flourishing and gradually becoming a new drive for economic growth. The construction of the business environment in Chinese urban agglomerations has entered a new stage of institutional openness. Fully and effectively promoting resource sharing and collaborative development is of great practical significance for improving the level of the business environment. Based on China's urban panel data from 2011 to 2021, this paper systematically assessed the impact and mechanism of the construction of national urban agglomeration on the level of business environment by using the multi-period DID and spatial DID models. The results indicate that the construction of urban agglomerations has significantly improved the level of regional business environment, and the results remain robust even after robustness testing. It has spatial spillover effects on adjacent and economically structurally similar cities. Heterogeneity analysis showed that the improvement of the business environment in resource-based cities was relatively small, while the improvement in non resource-based cities was significant. Emerging cities had a more flexible business environment. Mechanism testing indicated that urban agglomerations could optimize the business environment through pathways such as economies of scale, factor agglomeration, and opening up to the outside world. |
