群际接触与国家建构：来自西班牙兵役的证据

中文摘要

我们利用一项全国性抽签制度——该抽签将应征入伍者随机分配至西班牙境内不同的军区——研究群际接触对国家建构的长期效应。对于出生于西班牙认同较弱地区的男性，我们发现被分配到其他地区服兵役会大幅提高其自我认同为西班牙人的程度，提高其在全国选举中投票的可能性，并降低其投票给地区主义政党的概率。此外，为支持群际接触是这些结果背后的主要机制，我们发现跨地区流动者比未流动者更可能有来自其他地区的朋友。

Abstract

We study the long-term effects of intergroup contact on nation building by exploiting a national lottery that randomly allocated conscripts to different military areas across Spain. For men born in regions that feature a weak Spanish identity, we find that being assigned to military service in a different region substantially increases self-identification as Spanish, increases the likelihood of voting in national elections and reduces the probability of voting for a regionalist party. Moreover, in support of intergroup contact as the main mechanism behind these results, we find that movers are more likely than nonmovers to have friends from other regions.
