Research on the Impact Mechanism of Pilot Policies in Free Trade Zones on Urban Common Prosperity

推进共同富裕是“十四五”期间我国经济社会发展的重要目标，如何促进共同富裕是当前亟待解决的重要问题。本研究以2003~2021年全国280个城市的面板数据为样本，分析了自贸区设立对共同富裕的影响，以及产业集聚、数字经济水平的中介效应。主要结论包括：自贸区设立显著提升共同富裕水平；自贸区设立有利于当地产业集聚和数字经济水平的提升；同时产业集聚和数字经济水平在自贸区设立和共同富裕水平之间起中介作用。这些研究结果为自贸区政策的制定和实施提供了重要的参考，同时也为理解自贸区在共同富裕水平的作用机制提供了深入的理论支持。
Promoting common prosperity is an important goal of China’s economic and social development during the 14th Five-Year Plan period, and how to achieve common prosperity is an urgent issue that needs to be addressed. This study employs panel data from 280 cities across China from 2003 to 2021 to examine the impact of free trade zone (FTZ) establishment on common prosperity, as well as the mediating effects of industrial agglomeration and digital economy levels. The main conclusions are as follows: the establishment of FTZs significantly enhances the level of common prosperity; FTZ establishment is conducive to promoting local industrial agglomeration and improving the level of the digital economy; and both industrial agglomeration and digital economy levels play a mediating role between FTZ establishment and the level of common prosperity. These research findings provide important references for the formulation and implementation of FTZ policies and offer in-depth theoretical support for understanding the mechanisms through which FTZs influence common prosperity.
