数字服务贸易壁垒对数字服务出口的影响效应研究

Research on the Impact of Digital Service Trade Barriers on Digital Service Exports

文章从数字服务贸易限制性措施和双边监管政策分歧两个层面剖析了数字服务贸易壁垒的贸易效应,基于2014-2021年中国对76个国家的数字服务出口数据,实证分析数字服务贸易壁垒对我国数字服务出口的影响机制。研究表明:数字服务贸易限制性措施和监管政策分歧均对我国数字服务出口产生负向影响,且监管政策分歧的影响程度更大。数字服务贸易壁垒通过增加双边服务贸易成本抑制数字服务出口;国家间的互联网发展水平越接近,签署的RTA数字贸易规则条款深度水平越高,越能削弱贸易壁垒对数字服务出口的负面效应。影响效应还存在着国家层面的异质性。因此,加强双边数字贸易合作、加快数字技术创新与普及应用,有利于推动我国数字服务贸易出口规模和质量的提高。

This article analyzes the trade effects of digital service trade barriers from two perspectives:restrictive measures on digital service trade and differences in bilateral regulatory policies.Based on China's digital service export data to 76 countries from 2014 to 2021,it empirically analyzes the impact mechanism of digital service trade barriers on China's digital service exports.Research has shown that restrictive measures and regulatory policy differences in digital service trade have a negative impact on China's digital service exports,but regulatory policy differences have a greater impact.The digital service trade barrier suppresses China's digital service exports by increasing service trade costs.The closer the level of internet development between countries,the higher the depth of the signed RTA digital trade rules and regulations,which can weaken the negative effects of trade barriers on digital service exports.The impact effect still exists in country heterogeneity.Therefore,Strengthening bilateral digital trade cooperation,accelerating digital technology innovation and popularization,are conducive to promoting the improvement of the scale and quality of China's digital service trade exports.
