本文建立了一个异质性企业模型，分析了不同生产阶段的选择对贸易诱发的产业内资源再配置的影响。在两国对称的情况下，输入品和最终产品的交易成本都受制于选择，我们表明，由于外延边际的额外调整，中间产品的贸易弹性内生地大于最终产品的贸易弹性。我们还表明，当且仅当国内投入份额小于国内产出份额时，投入贸易自由化的福利收益大于产出贸易自由化的福利收益。
This article develops a heterogeneous firm model to analyze selection effects at different production stages on trade‐induced intra‐industry resource reallocations. Using a two‐country symmetric setting in which both inputs and final goods are costly to trade subject to selection, we show that the trade elasticity of intermediate goods is endogenously greater than that of final goods due to an extra adjustment in the extensive margin. We also show that the welfare gains from input trade liberalization are greater than those from output trade liberalization if and only if the domestic input share is smaller than the domestic output share.
