Replication Data for: Change in Migrants’ Political Attitudes: Acculturation and Cosmopolitanization

This paper investigates change in international migrants' political attitudes. It theorizes a novel attitudinal typology distinguishing polity-specific attitudes influenced by national contexts and transnational attitudes forged by migratory experience. It applies the typology to four dimensions of political competition in contemporary Europe: redistribution, homosexuality, European integration, and immigration. The paper tests the new theory using cross-sectional and panel data spanning nearly 380,000 observations from 104 sending and 28 destination countries. It introduces a new strategy to model cross-classified hierarchical data, addresses issues inherent to group comparison, and pioneers two empirical inquiries into migrants' self-selection. The results show that migration prompts the acculturation of polity-specific attitudes and the cosmopolitanization of transnational attitudes. Migrants adopt their host countries' attitudes toward redistribution and homosexuality while developing a uniquely liberal outlook on European integration and immigration. These findings carry major implications for our understanding of attitudinal change and the dimensionality of the ideological space.本文探究国际移民的政治态度变迁。本文提出一种全新的态度类型学，区分出受国家语境影响的政体特异性态度（polity-specific attitudes），以及由移民经历塑造而成的跨国态度（transnational attitudes）。本文将该类型学应用于当代欧洲政治竞争的四大维度：再分配政策、同性恋权益、欧洲一体化以及移民议题。本文使用覆盖104个移民来源国与28个移民目的国、近38万条观测值的横截面数据（cross-sectional data）与面板数据（panel data），对这一新理论进行检验。本文提出一种用于建模交叉分类层级数据（cross-classified hierarchical data）的新策略，解决了群体比较中固有的方法论难题，并首次针对移民自我选择（self-selection）问题开展两项实证探究。研究结果显示，移民行为会推动政体特异性态度的文化适应，以及跨国态度的世界主义化。移民会接纳其接收国在再分配与同性恋权益议题上的态度，同时在欧洲一体化与移民议题上形成独具特色的自由主义立场。上述发现对于我们理解态度变迁以及意识形态空间的维度结构具有重要启示。
