Abstract

This paper evaluates the effect on livestock production and rural population of the land consolidation (LC) processes that occurred over recent decades in Asturias, an autonomous region located in north-west Spain. We use a novel Difference-in-Difference (DiD) model which allows for multiple LCs at different points in time and for spatial spill-overs. As many parishes have been involved in two or more LC processes, we test whether we can simplify our analysis using a specification for these parishes that accumulates the effect of consecutive, and often distant, LC processes. We find that this simplification can be implemented when we analyse the effect of the LC processes on parishes' livestock production, but not when we examine their effects on parish population. We find that parish livestock production increases on average by about 3% once we take into account spatial effects, and that LC processes have especially attenuated the decline in the number of farms in (coastal) parishes where dairy farms predominate. We do not find strong evidence regarding the effectiveness of LC processes in redressing rural depopulation, except in some of the parishes located in western Asturias.

在西班牙北部,土地整合是否能促进畜牧业生产并消除农村人口减少现象?
本文评估了西班牙西北部自治区阿斯图里亚斯近几十年来发生的土地整理过程对畜牧业生产和农村人口的影响。我们使用了一种新颖的差分(DiD)模型,该模型允许在不同时间点进行多次土地整理,并允许空间溢出效应。由于许多教区参与了两个或更多的立法进程,我们测试了是否可以通过对这些教区进行规范来简化我们的分析。我们发现,在分析立法进程对教区畜牧业生产的影响时,可以采用这种简化方法,但在研究立法进程对教区人口的影响时,则不能采用这种简化方法。我们发现,一旦考虑到空间效应,教区畜牧业生产平均增长约 3%,而 LC 过程尤其减缓了以奶牛场为主的(沿海)教区农场数量的下降。除了位于阿斯图里亚斯西部的一些教区外,我们没有发现其他有力的证据表明立法进程能够有效地解决农村人口减少的问题。
