我们建立了一个多国家的Dixit-Stiglitz贸易模型，并分析了产业区位和福利如何对以下变化做出反应：（i）运输摩擦（例如，基础设施、运输技术）;以及（ii）非运输摩擦（例如，关税、标准和法规）。我们发现，在非运输摩擦的变化，这通常是特定的原产地，不允许任何明确的预测，以改变行业的位置和福利，而在运输摩擦的变化，这通常不是特定的原产地，可能允许这样的预测。特别是，我们表明，减少运输摩擦发生在链接周围的空间网络是本地树弧帕累托福利改善。(C)2007 Elsevier B. V.保留所有权利。
We develop a multi-country Dixit-Stiglitz trade model and analyze how industry location and welfare respond to changes in: (i) transport frictions (e.g., infrastructure, transportation technology); and (ii) non-transport frictions (e.g., tariffs, standards and regulations). We show that changes in non-transport frictions, which are usually origin-destination specific, do not allow for any clear prediction as to changes in industry location and welfare; whereas changes in transport frictions, which are usually not origin-destination specific, may allow for such predictions. In particular, we show that reductions in transport frictions occurring at links around which the spatial network is locally a tree arc Pareto welfare improving. (C) 2007 Elsevier B.V.
