贸易自由化在多大程度上促进了全球和区域生产碎片化以及生产网络的形成？我们推导出结构方程的增值贸易流量，国内增值出口的内容（DVA）和增值出口（VAX）的比率，以及基于模型的措施，生产网络从多部门重力模型与部门间的联系。我们校准了模型，并进行了反事实分析，中国在2001年加入WTO。我们发现，相关的贸易成本的变化刺激了全球生产的碎片化，解释了约6-12%的下降，在世界DVA比率观察到2000年和2007年之间。对中国来说，反事实实验有力地复制了其DVA比率的增加，这是由出口加工区驱动的。此外，我们的研究结果表明，中国加入WTO是加强与邻国的生产网络背后的驱动力。(C)2018爱思唯尔B.

To what extent has trade liberalization contributed to global and regional production fragmentation and the formation of production networks? We derive structural equations for value added trade flows, the domestic value added content of exports (DVA) and the value added to exports (VAX) ratio, as well as model-based measures for production networks from a multi-sector gravity model with inter-sectoral linkages. We calibrate the model and perform a counterfactual analysis of China's WTO accession in 2001. We find that the associated trade cost changes spurred global production fragmentation, explaining about 6-12% of the decrease in the world DVA ratio as observed between 2000 and 2007. For China, the counterfactual experiment robustly replicates the increase in its DVA ratio, driven by the export-processing zones. Furthermore, our results imply that China's WTO accession was a driving force behind the strengthening of production networks with its neighbors. (C) 2018 Elsevier B.V. All rights reserved.
