区域贸易协定深度对全球价值链前向参与度的不对称影响——基于制度质量的视角

Asymmetric Effects of the Depth of RTA on Forward GVC Participation--From the Perspective of Institutional Quality

制度质量作为国家比较优势的来源,可能导致区域贸易协定深度对全球价值链前向参与度的不对称影响。本文利用世界投入产出数据库,通过构建动态区域贸易协定深度指标,论证了区域贸易协定深度对制造业全球价值链前向参与度的影响效应。研究发现:区域贸易协定深度每增加1个标准差,出口国对进口国的全球价值链前向参与度就提升3.65%。机制检验表明,出口国的制度质量是区域贸易协定深度促进全球价值链前向参与度的作用机制,但该机制仅表现在发达国家中,发展中国家通过该机制无法显著促进全球价值链前向参与度。

Institutional quality,as a source of national comparative advantages,may lead to the asymmetric effects of the depth of Regional Trade Agreement(RTA)on Global Value Chain(GVC).Based on the World Input-Output Database(WIOD),the RTA depth index was constructed to demonstrate the effects of the depth of RTA on the forward manufacturing GVC participation.The results show that for each standard deviation increase in the depth of RTA,the forward GVC participation of the exporter to the importer increases by 3.65%.Through test,this study finds that the institutional quality of the exporter is the mechanism by which RTA depth promotes the forward GVC participation.However,the mechanism is only manifested in developed countries,and developing countries cannot significantly promote the forward GVC participation through it.
