数字贸易壁垒对我国服务贸易竞争力的影响——基于发达国家样本
The Impact of Digital Trade Barriers on China’s Service Trade Competitiveness—Based on Developed Country Samples

数字贸易壁垒的强化，将会对服务贸易造成一定程度的影响。本文使用OECD数据库的DSTRI，选取30个样本发达国家2014~2021年的数据研究数字贸易壁垒对我国服务贸易竞争力的影响，结果表明：发达国家数字贸易壁垒总体对我国服务贸易总体竞争力存在显著抑制效应，且对我国细分行业竞争力的影响存在异质性；同时发达国家数字贸易壁垒下属细分领域对我国服务贸易竞争力存在异质性影响；最后，使用调节模型进行机制分析得到，我国与发达国家签署贸易协定能降低数字贸易壁垒对我国服务贸易竞争力的抑制影响。
The strengthening of digital trade barriers will have a certain degree of impact on service trade. This article uses DSTRI from the OECD database and selects data from 30 developed countries from 2014 to 2021 to study the impact of digital trade barriers on China's service trade competitiveness. The results show that digital trade barriers from developed countries have a significant inhibitory effect on China’s overall service trade competitiveness, and there is heterogeneity in their impact on China’s segmented industry competitiveness. At the same time, the sub sectors of digital trade barriers in developed countries have heterogeneous impacts on China’s competitiveness in service trade. Finally, using a regulatory model for mechanism analysis, it was found that signing trade agreements between China and developed countries can reduce the inhibitory impact of digital trade barriers on China’s service trade competitiveness.
