区域贸易协定服务贸易条款深度对增加值贸易关联的影响

The Effect of Clause Depth of RTA Service Trade Provisions on Trade in Value-added Linkage

本文基于区域贸易协定数据库对涉及42个国家(地区)2000—2014年的区域贸易协定服务贸易条款深度进行测度,并利用全球价值链指标数据库考察了RTA服务贸易条款深度对增加值贸易关联的影响。研究结果表明:区域贸易协定服务贸易条款总深度对增加值贸易关联存在显著的促进作用,其中,服务章节引用《服务贸易协定》相关规则、包含国民待遇条款、允许无商业存在条件下提供贸易、允许自然人流动以及包含审议条款能够显著提高缔约国之间的增加值贸易关联。进一步研究发现:一方面,经济水平发展相似的国家深化服务贸易条款深度可以获得更高的增加值贸易关联水平;另一方面,服务贸易条款深度一体化可以通过削减双边国家的贸易成本提高企业出口预期信心,还可以通过技术溢出效应进一步吸收来自国外高效率的生产环节,提升双边国家的价值链嵌入水平。

Based on the database of Regional Trade Agreements,the depth of service trade provisions in Regional Trade Agreements involving 42 countries during the period from 2000 to 2014 was horizontally measured,and then the global value chain index database was used to investigate the impact of the depth of RTA service trade provisions on the relevance of the trade in value-added linkage.It is found that the total depth of RTA service trade terms plays a significant role in promoting the added value trade association.Among them,the services chapters such as GTAS related rules,national treatment,the right of non-establishment,the movement of natural persons and the review provisions can significantly improve the trade in value-added linkage.Further research shows that the countries with similar economic development level could obtain higher value-added trade association level by deepening the service trade provisions.On the other hand,the deep integration of service trade provisions could improve enterprises’confidence in export expectation by reducing the trade cost of bilateral countries,and enhance the value chain embedding level of bilateral countries by using technology spillover effect to further absorb efficient production links from abroad.
