摘要
作为数字经济高质量发展的硬件支持,数字基础设施对经济发展的促进作用已得到了日益广泛的论证。日趋严峻的国际形势对出口产品质量提出了前所未有的高要求,那么,数字基础设施发展能否有效促进中国企业出口产品质量提升?本文首先从信息基础设施与融合基础设施两个维度对城市数字基础设施发展水平进行综合测度,全面准确刻画了数字基础设施中“新一代信息技术”发展与融合应用情况,然后基于中国海关数据库与中国工业企业数据库的匹配数据,从微观企业层面系统考察了数字基础设施发展对企业出口产品质量的影响及作用机制。实证结果显示,数字基础设施发展显著促进了企业出口产品质量的提升,且该结论在独立样本(2016—2020年)、一系列稳健性检验和处理内生性问题后始终成立;机制探究结果显示,数字基础设施建设便利了要素流通和降低了交易成本,是企业出口产品质量促进效应的两个作用机制;异质性分析发现,这种促进效应在非国有、融资约束水平较低及位于外围城市的企业中更为显著。在数字经济迅猛发展背景下,本文为促进数字经济发展,政府更好地规划数字基础设施建设,助推外贸高质量发展等提供了证据支持。
economy,the:As the hardware foundation for the high-quality development of the digital role of digital infrastructure in promoting economic development has been increas-ingly widely demonstrated.The increasingly challenging international situation has placed unpre-cedentedly high demands on the quality of exported products.Can the development of digital infrastructure effectively promote the improvement of the quality of Chinese enterprises'export products?This paper first conducts a comprehensive measurement of the development level of urban digital infrastructure from two dimensions:information infrastructure and converged in-frastructure,comprehensively and accurately portraying the development and converged applica-tion of"new-generation information technology"within digital infrastructure.Subsequently,based on matched data from the China Customs Data and the Chinese Industrial Enterprise Data-base,systematically examines the impact and mechanism of digital infrastructure development on the quality of enterprise-exported products at the micro-enterprise level.Empirical results show that the development of digital infrastructure significantly promotes the improvement of the quality of enterprise-exported products,and this conclusion remain robust in a series of checks and after addressing endogeneity problem.Further analysis shed light on the mechanism of facili-tating factor circulation and reducing transaction costs.Heterogeneity analysis reveals that the quality enhancing effect is more significant in non-state-owned enterprises,those with lower financing constraints,and those located in peripheral cities.In the rapid development of the digi-tal economy,our work provides supports to the promotion of digital economic development,planning of digital infrastructure construction,high-quality development of foreign trade and so on.
