A prominent argument as to why countries sign “deep” preferential trade agreements (PTAs) is to foster global value chains (GVCs) operations. By exploiting a new dataset on the content of PTAs, this paper quantifies the positive impact of deep PTAs on GVC participation, mostly driven by value-added trade in intermediate rather than in final goods and services. On average, each additional policy areas increases the domestic and the foreign value added of intermediates by 0.48 and 0.38%. Deep PTAs facilitate integration in industries with higher levels of value added. Their content also matters for GVC integration by income group.

深度贸易协定和全球价值链

关于国家为何签署“深化”优惠贸易协议（PTA）的一个突出论点是促进全球价值链（GVC）的运营。通过利用有关PTA内容的新数据集，本文量化了深PTA对GVC参与的积极影响，这主要是由中间产品而非最终产品和服务的增值贸易驱动的。平均而言，每增加一个政策领域，中间体的国内和国外增加值就会增加0.48和0.38％。深入的PTA促进了高附加值行业的整合。它们的内容对于按收入组分类的GVC也很重要。
