Trade spillover effects of transport infrastructure investments: a structural gravity analysis for EU regions
使用结构引力模型，评估欧盟凝聚政策道路投资对区域间贸易和福利的影响，发现目标区域实际出口增加0.03%，实际GDP平均增长0.15%。
A structural gravity model is used to estimate the regional trade and welfare effects of the reduction in transport costs between and within European Union regions induced by European Union Cohesion Policy road infrastructure investment. The results imply that, in targeted regions, the policy increases interregional real exports by 0.03% and real gross domestic product (GDP) by 0.15% on average. The gains in real GDP are the highest in the regions receiving most funds. Although the policy always leads to more goods being shipped, for some regions it implies less trade external to the region and more trade within.
