本文探讨了基础设施质量对一国贸易绩效的影响，估算了一个包含双边关税和多项基础设施质量指标的引力模型。该文件探讨了基础设施质量（道路、机场、港口和电信以及清关所需时间）对双边贸易总额以及汽车、服装和纺织行业贸易的影响。为了获得无偏估计量，在引力方程中引入了关税和偏远的多边阻力。此外，通过估计固定效应模型来测试结果的稳健性，其中包括基础设施质量的双边指数。结果可概括为四个主要发现：（i）双边关税对贸易产生显着的负面影响，而双边关税在双边流动的重力回归中通常被忽略； (ii) 基础设施的质量是贸易绩效的重要决定因素； (iii) 在所有基础设施指标中，港口效率似乎对贸易影响最大； (iv) 及时性和电信接入对于服装和汽车行业的出口竞争力而言相对更为重要。
This paper explores the role that quality of infrastructure has on a country's trade performance, estimating a gravity model that incorporates bilateral tariffs and a number of indicators for the quality of infrastructure. The paper looks at the impact of the quality of infrastructure (road, airport, port and telecommunication, and the time required for customs clearance) on total bilateral trade and on trade in the automotive, clothing and textile sectors. In order to obtain unbiased estimators, multilateral resistances for tariffs and remoteness are introduced in the gravity equation. Moreover, the robustness of the results is tested by estimating a fixed-effect model, where bilateral indexes of the quality of infrastructure are included. The results can be summarised in four main findings: (i) bilateral tariffs, generally neglected in gravity regression of bilateral flows, have a significant negative impact on trade; (ii) quality of infrastructure is an important determinant of trade performance; (iii) port efficiency appears to have the largest impact on trade among all indicators of infrastructure; (iv) timeliness and access to telecommunication are relatively more important for export competitiveness in the clothing and automotive sector respectively.
