摘　　要：将“宽带中国”试点政策视为准自然实验,基于2007—2019年沪深A股上市公司数据进行分析。研究发现:网络基础设施建设显著提升了企业的数字化转型水平,特别是对企业底层技术运用的促进作用更加明显;网络基础设施通过缓解融资约束、提升研发投入和促进绿色创新间接促进企业数字化转型;异质性分析表明,非国有、中西部以及高科技企业的数字化转型水平受政策影响更加显著。This study considers the"Broadband China"pilot policy as a quasi-natural experiment,utilizing data from A-share listed companies in Shanghai and Shenzhen from 2007 to 2019.The findings indicate that the construction of network infrastructure significantly enhances the level of enterprise digital transformation,particularly in promoting the utilization of foundational technologies.Furthermore,network infrastructure indirectly facilitates enterprise digital transformation by alleviating financial constraints,increasing investment in R&D,and promoting green innovation.Heterogeneity analysis reveals that non-state-owned enterprises,Midwest enterprises and high-tech enterprises are more profoundly impacted by policies in terms of their level of digital transformation.
