摘　　要：保障企业供应链稳定是构建全国统一大市场与助力经济行稳致远的重要基础。本文基于2012—2022年中国A股上市公司数据,以市场准入负面清单制度为准自然实验,探究放松市场准入管制与企业供应链稳定的相关性。研究发现:放松市场准入管制能够促进企业供应链稳定,并且对导入期企业、非国有企业、高垄断行业以及供应链集中度高的企业供应链稳定的促进作用更强。机制检验表明,供给侧优化要素配置,需求侧释放消费潜能是该政策促进企业供应链稳定的重要渠道。进一步分析发现,将国内市场一体化纳入供应链稳定指标后,放松市场准入管制对新指标的正向效应更突出,表明放松市场准入管制对全国统一大市场具有助推作用。Ensuring the stability of enterprise supply chains is an important foundation for building a unified national market and promoting stable and far-reaching economic development.This article is based on data from Chinese A-share listed companies from 2012 to 2022,and uses the negative list system for market access as a natural experiment to explore the correlation between relaxing market access regulations and stabilizing enterprise supply chains.Research finds that relaxing market access regulations can promote the stability of enterprise supply chains,and have a stronger promoting effect on the stability of supply chains for enterprises in the import period,non-state-owned enterprises,high monopoly industries,and enterprises with high supply chain concentration.Mechanism testing shows that optimizing factor allocation on the supply side and unleashing consumption potential on the demand side are important channels for this policy to promote the stability of enterprise supply chains.Further analysis reveals that after incorporating domestic market integration into the supply chain stability index,the positive effect of relaxing market access regulations on the new index is more prominent,indicating that relaxing market access regulations has a promoting effect on the unified national market.
