This study aims to analyze trade efficiency in the context of Global Value Chains (GVC) participation and measure the impact of regional trade agreements (RTAs) on trade efficiency. The research will utilize a stochastic gravity model to estimate trade efficiency, which reflects the gap between actual and potential linkages in a frictionless world. Additionally, the study will investigate how the establishment of RTAs affects trade efficiency by considering countries' participation in GVCs. This empirical evidence will contribute to understanding the potential for further trade integration.The first stage of this research has successfully measured trade efficiency in East Asia and examined the impact of RTAs on trade efficiency. The estimation results indicate that RTAs generally improve trade efficiency among member countries in East Asia. Furthermore, I explored changes in trade efficiency between member and non-member countries, contributing to the understanding of trade diversion effects resulting from RTA formation. The results reveal that export diversion due to RTAs is uncommon in East Asia. However, the analysis indicates that imports of ASEAN countries tend to divert away from non-members.

本研究旨在分析全球价值链（GVC）参与背景下的贸易效率，并衡量区域贸易协定（RTA）对贸易效率的影响。这项研究将利用一个随机引力模型来估计贸易效率，它反映了在一个无摩擦的世界中实际联系和潜在联系之间的差距。此外，研究报告将通过考虑各国参与全球价值链的情况，调查区域贸易协定的建立如何影响贸易效率。这一实证将有助于理解进一步贸易一体化的潜力。本研究的第一阶段成功地测量了东亚的贸易效率，并研究了区域贸易协定对贸易效率的影响。估算结果表明，区域贸易协定普遍提高了东亚成员国之间的贸易效率。此外，我探讨了成员国和非成员国之间的贸易效率的变化，有助于理解RTA的形成所产生的贸易转移效应。结果表明，由于区域贸易协定的出口转移是不常见的东亚。然而，分析表明，东盟国家的进口往往从非成员国转移。
