摘　　要：在分析数字经济发展影响出口开放度理论机制的基础上,利用中国31个省级行政单位(不含港澳台)2017—2019年面板数据实证检验数字经济与我国出口开放的关系,并考察这一关系是否受异质性因素(是否沿海、是否拥有自由贸易试验区、企业电子商务化水平)的影响,以及利用中介模型发掘数字经济发展影响出口开放度的作用路径。研究发现:数字经济发展可以显著提高出口开放度,但这一关系受异质性因素的影响,位于沿海省份、拥有自由贸易试验区省份的数字经济发展对出口开放度的影响更大;而企业电子商务化水平却对这一关系起到削弱作用;基于中介效应的研究则证实了省市创新能力在数字经济与出口开放度之间扮演部分中介的角色。本研究旨在为发挥数字经济对出口开放度的促进作用提供独特的理论指导和思路借鉴。Based on the analysis of the theoretical mechanism of the impact of digital economy development on export opening up degree,the relationship between the development of digital economy and export opening up is empirically studied by using the panel data of 31 provincial administrative units(excluding Hong Kong,Macao and Taiwan)in China from 2017 to 2019.Whether the relationship is affected by the heterogeneous factors(such as coastal or not,having free trade zones or not,and the e-commerce level of enterprises)is discussed.By using the intermediary model,the path of the impact of digital economy development on export opening up is explored.The main conclusions are as follows:the development of digital economy can significantly improve the export opening up,but the relationship is affected by heterogeneous factors,that is,the development of digital economy in coastal provinces and provinces with free trade zones has a greater impact on the export opening up.However,the e-commerce level of enterprises weakens the relationship.The research on intermediary effect confirms that innovation capacity plays a partial intermediary role between digital economy and export opening up.The conclusion provides unique theoretical guidance and reference for the digital economy to promote export opening up.
