摘　　要：作为新一代经贸规则的一部分,数字服务贸易规则对国家间经贸往来起到愈发重要的作用。本文通过将OECD-DSTRI数据库和WIOD数据库进行匹配,实证检验了数字服务贸易壁垒对增加值贸易强度的影响。研究表明,数字服务贸易壁垒抑制了双边增加值贸易强度,主要通过提高贸易成本和降低生产率两条路径实现,互联网发展水平能够削弱数字服务贸易壁垒对增加值贸易强度的抑制作用;数字服务贸易壁垒对增加值贸易强度的抑制作用具有异质性,对经济发展水平较高国家的抑制作用更大,在2008年全球金融危机前的抑制作用更加明显;数字服务贸易壁垒对服务行业的增加值贸易强度的抑制作用最大,对农业的抑制作用最小;数字服务贸易壁垒对知识密集型和资本密集型行业的抑制作用较大,对劳动密集型行业的抑制作用较小。本文的研究结论为通过降低数字服务贸易壁垒加强双边国家的贸易联系提供了经验证据。Digital service trade rules are playing an increasingly important role in economic and trade exchanges between countries.This article tests the impact of digital service trade barriers on the intensity of value-added trade by matching the OECD DSTRI database with the WIOD database.Research has shown that digital service trade barriers inhibit the intensity of bilateral value-added trade and are achieved through two paths:trade costs and labor productivity.At the same time,the level of internet development can weaken the inhibitory effect of digital service trade barriers on the intensity of value-added trade.Further research has found that the inhibitory effect of digital service trade barriers on the intensity of valueadded trade is heterogeneous;Its inhibitory effect on countries with higher levels of economic development is greater,and its inhibitory effect was more pronounced before the 2008 financial crisis;The digital service trade barrier has the greatest inhibitory effect on the value-added trade intensity of the service industry,and the least inhibitory effect on agriculture;The trade barriers to digital services have a greater inhibitory effect on knowl-edge intensive and capital intensive industries,but a smaller inhibitory effect on labor-intensive industries.
