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 significant 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.

为现代增长铺平道路：西班牙波旁之路

本文分析了 1787 年至 1857 年间西班牙道路建设对当地人口增长的影响。我们发现与道路可达性相关的市场潜力的增加对当地人口增长产生了显着影响。对于职业结构更加多元化的城市来说，这种影响要大得多。相比之下，新网络对人口增长的影响在邻近但无法直接通往道路的城市中是负面的。我们将这些发现解释为新道路导致农村人口向农村人口迁移过程的证据。
