我们建立了一个具有多阶段制造业价值链的贸易定量模型，该模型以冰山贸易成本和产品和生产阶段的技术差异为特征。我们通过模拟矩法估算技术和贸易成本，匹配最终产品和投入的双边运输。应用该模型，我们研究了比较优势和贸易成本如何塑造全球价值链和贸易流的结构。随着贸易成本水平的福尔斯下降，我们发现，由于价值链的内生重组（出口平台生产的增加），双边贸易对贸易成本的弹性增加。然而，令人惊讶的是，世界贸易对贸易成本的弹性并没有因多阶段生产而扩大。
We build a quantitative model of trade with multistage manufacturing value chains, which features iceberg trade costs and technology differences across both goods and production stages. We estimate technology and trade costs via the simulated method of moments, matching bilateral shipments of final goods and inputs. Applying the model, we investigate how comparative advantage and trade costs shape the structure of global value chains and trade flows. As the level of trade costs falls, we show that the elasticity of bilateral trade to trade costs increases, due to the endogenous reorganization of value chains (increased export platform production). Surprisingly, however, the elasticity of world trade to trade costs is not magnified by multistage production.
