Evaluation and optimization of business environment based on sustainable development perspective: Exploring the role of the reform of government functions

The existing research on the business environment index system has a single viewpoint, which can hardly reflect the requirements of SDGs on the business environment. Few studies have focused on the “front end” factors determining the business environment. Based on panel data from 2011 to 2020, this study measures the business environment in 275 Chinese cities and uses the ArcGIS software and Natural Breaks (Jenks) to examine its spatiotemporal characteristics. The PSM‐DID model is utilized to examine the policy implications of the reform of government functions on the business environment. The findings demonstrate that China's urban business environment's total score has risen, and its geographic characteristics are “strong in the east and weak in the west.” Among the various sub‐dimensions of the business environment, the largest contribution is the infrastructure environment, followed by the rule of law environment. The reform of government functions can improve the business environment from the second year onward. Regional and city‐level heterogeneities exist in the effects of the reform of government functions on the business environment. In addition, informatization level, population density, and consumption level can optimize the business environment. This study provides a guide for accelerating the creation of a marketized, legalized, international, and sustainable business environment.
