高水平区域贸易协定对价值链贸易的影响--基于规则文本深度的研究

The Impact of High Standard RTAs on GVC Trade--A Study on the Text Depth and Quality

本文通过分析中国已签区域贸易协定文本的深度,构建RTA深度指数,从增加值贸易的视角研究不同深度的RTA的贸易效应,探讨新一代贸易投资规则对价值链贸易的影响。研究结果表明:中国与贸易伙伴之间签署的RTA在WTO-plus条款上较为深入,而在WTO-extra议题中的覆盖率较低。无论是从总贸易角度、中间品贸易角度还是增加值贸易角度,区域贸易协定对伙伴方贸易流量都具有显著的促进作用,协定内容深度越深,对贸易的促进作用越大。同时,区域贸易协定的条款差异、签订对象国家(地区)的外部环境影响了RTA贸易效应的显著差异。本文结论为中国参与高水平贸易规则谈判,完善全球价值链治理提供了实证依据和政策参考。

When the multilateral trading system is hard to meet the needs of all parts under the global value chain(GVC)specialization,high⁃level regional trade agreements(RTAs)provide such kind of power to balance trade interests and reshape a new govern⁃ance system for GVC.By constructing the RTAs depth index,this paper therefore studied the depth of regional trade agreements conducted by China.We also analyzed the trade effect of RTAs with different depths from the perspective of value⁃added trade.The results show that the RTAs signed by China has more WTO⁃plus clauses,while they are lack of WTO⁃extra issues.It is noted that RTAs have significantly positive effects on the trade flow among partners with respect to total trade,intermediate trade and value⁃added trade.The deeper the RTAs depth index is,the greater trade flows the RTAs brings.In addition,we also find that both the texts of RTAs and the external environment of partners decide the trade effects of RTAs.The conclusion of this paper provides empirical basis and policy ref⁃erence for China to participate in high⁃level trade rules negotiation and improve global val⁃ue chain governance.
