区域贸易协定深化对美国亚太价值链影响力的影响

Influence of the Deepening RTA on the U.S.Asia-Pacific Value Chain

利用WTO-PTA和OECD-TiVA数据库分别构建了度量区域贸易协定(RTA)深度与美国亚太价值链影响力的指标体系,并全方位考察了RTA深化对美国亚太价值链影响力的影响及其作用机制。结果表明:RTA深化显著增强了美国亚太价值链影响力,在经过一系列稳健性检验后该结论依然成立。此外,RTA深化对美国亚太价值链影响力的强化作用存在显著的条款内容、条款领域、经济体对、地理区域、协定类型及创新能力异质性。机制检验表明,RTA深化主要通过扩大亚太价值链地位差异和降低贸易成本来增强美国亚太价值链影响力。基于中国样本的回归结果发现,RTA深化显著增强了美国对中国与其他亚太经济体价值链合作的影响力;“WTO+”条款、关税条款和经济性领域条款深化的强化作用更为强劲。

This paper uses WTO-PTA database and OECD TiVA database to build an indicator system to mea-sure the depth of regional trade agreements(RTA)and America's control over the Asia Pacific value chain,and com-prehensively examines the impact of RTA deepening on America's control over the Asia Pacific value chain.The re-sults show that the deepening of RTA has significantly enhanced America's control over the Asia Pacific value chain,and this conclusion is still valid after a series of robustness tests.In addition,RTA deepening has significant heteroge-neity in terms of content,scope,economic pairs,geographical regions,types of agreements,and innovation capabilities.The mechanism test shows that RTA deepening mainly strengthens America's control over the Asia Pacific value chain by expanding the difference in the status of the Asia Pacific value chain and reducing trade costs.This study provides a reference for China to break through the containment of the Asia Pacific value chain of the United States with RTA.The regression results based on the Chinese sample found that RTA deepening significantly strengthened the control of the United States over the value chain cooperation between China and other asia-pacific economies,"WTO+"pro-visions,tariff provisions and economic areas of the deepening of the provisions of the stronger role.
