Paving the way to modern growth: The Spanish Bourbon roads
研究了1787至1857年间西班牙道路建设对当地人口增长的影响，发现道路可达性带来的市场潜力显著促进了人口增长，尤其对职业结构多样化的地区影响更大，而邻近但无直接道路的地区人口增长为负，揭示了道路引发的农村间迁移过程。
This paper analyses the impact that Spanish road construction had on local population growth between 1787 and 1857. We find that the increase in market potential associated to road accessibility had a substantial effect on local population growth. The impact was substantially higher on the municipalities that had a more diversified occupational structure. By contrast, the effect of the new network on population growth was negative in municipalities close but without direct access to the roads. We interpret these findings as evidence of a process of rural-to-rural migration due to the new roads.
