【摘要】 在自由贸易协定中引入数字贸易规则已成为世界各国参与数字贸易国际治理的重要途径，采取数字贸易限制性措施成为应对相应数字贸易规则的常规手段，由此产生的数字贸易壁垒对价值链攀升有何影响值得探究。文章通过构建行业层面数字贸易壁垒指数与价值链位置指数，探讨数字贸易壁垒对价值链攀升的影响。研究结果发现：数字贸易壁垒阻碍了全球价值链攀升，该结论在一系列检验后依然稳健；区域跨境数据流动异质性分析表明，数字贸易壁垒对间接政策区域的抑制性最小，行业异质性分析表明，数字贸易壁垒会显著阻碍中高技术制造业和现代服务业价值链攀升；机制检验结果表明，数字贸易壁垒通过提高中间产品贸易成本及最终产品贸易成本阻碍全球价值链攀升。更多还原

【Abstract】 The introduction of digital trade rules into free trade agreements has become an important way for the countries around the world to participate in international governance of digital trade, and the adoption of digital trade restriction measures has become a conventional mean to deal with the corresponding digital trade rules. It is worth exploring the impact of the resulting digital trade barriers on value chain climbing. This paper probes into the impact of digital trade barriers on value chain climbing by constructing industry-level digital trade barrier index and value chain position index. The research results show that digital trade barriers hinder global value chain climbing and this conclusion remains robust after a series of tests; the heterogeneity analysis of regional cross-border data flow reveals that digital trade barriers have the least inhibitory effect on indirect policy regions, and the industry heterogeneity analysis indicates that digital trade barriers will significantly hinder value chain climbing of medium-tech and high-tech manufacturing industries and modern service industries; the mechanism test results show that digital trade barriers hinder global value chain climbing by increasing trade costs of intermediate products and final products.更多还原
