出口如何应对国内贸易成本的变化？特别是邻近港口出口成本变化对一个港口的出口影响有多大？为了回答这些问题，我们扩展了标准的贸易模型与异质企业有一个多港口结构出口是受港口特定的本地运输成本和港口特定的固定出口成本以及国际双边贸易成本。我们推导了一个多港口的重力方程，并表明，由于企业异质性的重力扭曲是有条件的港口比较优势，并在差异化的港口之间的出口替代。我们使用2011年东日本大地震和随后的海啸来证明替代效应。这一事件使我们能够衡量没有直接受到灾难影响的港口的贸易反应。我们发现了总贸易的替代效应以及部门层面和目的地的差异化。
How do exports respond to changes in domestic trade costs? In particular how strongly are exports from one port affected by changes in the cost of exporting at neighbouring ports? To answer these questions we extend the standard trade model with heterogeneous firms to have a multiple port structure where exporting is subject to port specific local transportation costs and port specific fixed export costs as well as international bilateral trade costs. We derive a gravity equation with multiple ports and show that gravity distortion due to firm heterogeneity is conditional on port comparative advantage and resulting substitution of export across differentiated ports. We present evidence of the substitution effect using the 2011 Great East Japan Earthquake and following tsunami. This event allows us to measure the response of trade on ports not directly affected by the disaster. We detect a substitution effect for aggregate trade as well as differentiation at the sectoral level and by destination.
