2227专业化分工是企业成长的重要基础和一国经济增长的根本源泉，同时也是新形势下提高供给质量和供给效率的重要途径。深入探究国内市场专业化分工的内在机理，对于增强国内大循环内生动力至关重要。文章以“创建社会信用体系建设示范城市”政策作为社会信用环境的代理变量，借助双重差分法，实证考察了社会信用环境改善对企业专业化分工的影响。研究发现，社会信用环境改善显著促进了企业专业化分工，这主要是通过降低企业面临的外部交易成本而实现。异质性分析发现，当内部管控成本较高时，社会信用环境改善对企业专业化分工的促进作用有所减弱；而在非国有企业、制造业以及法治环境较好的地区，社会信用环境改善的专业化分工效应更为明显。进一步分析表明，社会信用环境改善对企业专业化分工的推动作用促进了企业全要素生产率的增长。文章揭示了社会信用环境对企业行为的影响，不仅为理解企业分工提供了一种新的视角，也丰富了信用经济学领域的相关研究。
