While many studies focus on the impact of trade agreements, the literature has not focused on the extent of their implementation, in terms of the aspects agreed upon therein. In this article, we identify the past achievements of economic partnership agreements (EPAs) in the East Asian region in terms of tariff removals and suggest room for further economic benefits from trade liberalisation in the region. Second, we incorporate the HS6-level tariff concession dataset, which distinguishes between tariff removals agreed in these EPAs in East Asia but not yet implemented, from existing overall tariffs in 2011, in the Global Trade Analysis Project (GTAP) Database, which only incorporates enforced tariff reductions through the base-year applied tariffs. To analyse future trade integration, we include commitments that are not yet implemented. This allows us to analyse partial versus full enforcement of tariff concession commitments. Our results suggest that taking those commitments into account matters economically in East Asia. JEL Classification: D58, F13, F14, F15, F17

关税减让在东亚的作用分析

尽管许多研究集中于贸易协定的影响，但文献并未就协定中商定的方面集中于其执行的程度。在本文中，我们从关税减免的角度确定了东亚地区经济伙伴关系协议（EPA）的过去成就，并为该地区贸易自由化带来了进一步的经济利益。其次，我们在全球贸易分析项目（GTAP）数据库中纳入了HS6级关税减让数据集，该数据集将东亚这些EPA中商定但尚未实施的关税减免与2011年的现有总体关税区分开来。通过基准年应用关税强制实施关税削减。为了分析未来的贸易整合，我们包括尚未落实的承诺。这使我们能够分析关税减让承诺的部分执行与全部执行。我们的结果表明，在东亚，考虑到这些承诺在经济上很重要。JEL分类：D58，F13，F14，F15，F17
