Despite the recognition that trade policy—in particular, tariff regimes and rules of origin—can affect the geography of production, much GPN analyses pay scant attention to the tariff context of the sector studied. This paper proposes an analytical framework to more effectively integrate these regimes into applied GPN research. We test the framework, drawing on analysis of exports to the EU market in four sectors: textiles and apparel, floriculture, fisheries and leather goods. The analysis confirms that, in the presence of high tariffs, preferences do seem to impact on sourcing for the EU market.

关税制度对全球生产网络 (GPN) 的影响

尽管认识到贸易政策——尤其是关税制度和原产地规则——会影响生产地理，但许多 GPN 分析很少关注所研究部门的关税背景。本文提出了一个分析框架，以更有效地将这些制度整合到应用 GPN 研究中。我们根据对欧盟市场出口的四个部门的分析来测试该框架：纺织品和服装、花卉、渔业和皮革制品。分析证实，在存在高关税的情况下，优惠似乎确实会影响欧盟市场的采购。
