摘　　要：基于2007—2020年A股上市公司数据,本文检验了企业数字化对其出口绩效的影响,考察了企业生产率、公司治理水平与信息成本的机制作用。研究结果表明,企业数字化能够显著提高出口绩效,在进行稳健性和内生性检验后该结论依然成立。机制分析表明:企业数字化通过提高企业生产率、降低信息成本和优化公司治理三种渠道提升企业出口绩效;不同分类维度的企业转型促进作用存在异质性。进一步分析发现,普通中小型企业和科技型中小企业的数字化对于出口绩效的影响分别具有显著的正U型和倒U型的非线性特征。This paper examined the influence of digitalization on enterprises'export performance,and the functions of corporate productivity,corporate management,and information cost,based on data of China,s A-share listed companies from 2007 to 2020.The study results show that enterprise digitalization can enhance export performance to a large extent.Such statement remains valid through both robustness and endogeneity tests.Mechanism analysis indicates that enterprise digitalization enhances export performance through three channels—boosting corporate productivity,reducing information cost,and optimizing corporate management.It is found that the positive effects of enterprise transformation in different fields are heterogeneous.Further analysis suggests that digitalization's impacts on export performance are quite different between common small and mediumsized enterprises(SMEs)and small and medium-sized technology-based enterprises.While the former shows a prominent U-shaped non-linear feature,the latter displays an inverted U-shaped one,based on which the study examines the threshold effects in enterprise size and sci-tech innovation respectively.
