摘要 本文利用法国省级边界周围的空间准实验变异，提供了新的证据，表明区域边界会扰乱周边经济活动，即通勤流、辐射范围和居住密度。区域边界处地方交通网络缺乏整合——导致跨越边界时产生4.5公里的出行距离惩罚——解释了所观察到的边界效应。使用空间可量化均衡框架并考虑建设成本，一项政策模拟表明，整合地方交通网络会使实际人均居民收入平均增长6.36%。
Abstract
Abstract This paper exploits spatial quasiexperimental variation around French departmental borders to provide novel evidence that regional borders disturb surrounding economic activity; namely, commuting flows, catchment areas, and residential density. The lack of integration of local transport networks at regional borders—leading to a 4.5 km travel distance penalty when crossing borders—explains the observed border effects. Using a spatial quantifiable equilibrium framework and accounting for construction costs, a policy simulation exercise shows that integrating local transport networks leads to a 6.36% average growth in real per capita residential income.
