【摘要】 公平竞争审查是规制行政垄断的关键制度安排，对建设全国统一大市场、推动区域协调发展具有重要意义。基于2012—2023年中国281个城市的数据，以公平竞争审查制度的实施为准自然实验，采用双重差分模型实证检验公平竞争审查对地区经济差距的影响。研究结果表明，公平竞争审查能够缩小地区经济差距，有利于区域协调发展目标的实现。机制分析结果显示，公平竞争审查主要通过优化正式制度环境和非正式制度环境两条路径缩小地区经济差距。异质性分析表明，公平竞争审查存在明显的“拉拔效应”，更有利于降低审查力度较强、发展能力欠佳和竞争环境较弱地区的经济差距，有效缩小城市间的发展鸿沟。进一步研究发现，公平竞争审查对城市间经济差距存在收敛效应，但对城市内部经济差距具有分化效应，区域协调发展目标的实现呈现对象偏移倾向。因此，各地应积极推进公平竞争审查制度，营造要素自由流动的良好生态，依托全国统一大市场建设以缩小地区经济差距，促进区域协调发展。更多还原

【Abstract】 Fair competition review is a key institutional arrangement for regulating administrative monopolies, and it holds great significance for building a unified national market and advancing coordinated regional development. Based on the data from 281 cities in China spanning 2012 to 2023,this study takes the implementation of the fair competition review system as a quasi-natural experiment and employs a difference-in-differences model to empirically examine the impact of fair competition review on regional economic disparities. The results indicate that fair competition review can reduce regional economic disparities and facilitate the achievement of coordinated regional development goals. The mechanism analysis reveals that fair competition review narrows regional economic disparities primarily through channels that optimize the formal institutional environment and the informal institutional environment. The heterogeneity analysis shows that fair competition review exhibits a distinct “ pulling effect”, which is more effective in reducing the economic disparities in regions with stronger review intensity, weaker development capacity, and a less competitive environment, thereby effectively narrowing the “development gap” between cities. Further research reveals that fair competition review exerts a convergent effect on the economic disparities between cities, yet it has a differentiating effect on the economic disparities within cities. This reveals a tendency of target deviation in the realization of the coordinated regional development goals. Therefore, local governments should actively advance the fair competition review system, foster a sound ecosystem for the free flow of factors of production, and leverage the construction of a unified national market to bridge regional economic disparities and promote coordinated regional development.更多还原
