This paper outlines the methodology of DEMIG POLICY, a new database tracking around 6,000 migration policy changes in 45 countries between 1945 and 2014. The article conceptualizes the notion of migration policy change and presents the coding system used to operationalize policy content, changes in policy restrictiveness, as well as the magnitude of policy changes. The paper also discusses the potential of DEMIG POLICY to improve our understanding of the nature, evolution, and effectiveness of migration policies. Besides significantly extending the geographical and historical coverage of existing migration policy databases, DEMIG POLICY also tracks emigration policies in order to overcome the common 'receiving country bias' in migration research. By offering key insights into the main features of the largest migration policy database completed to date, this paper hopes to provide useful guidelines to improve future efforts to measure migration policies. Such improvement is crucial given the heated debates on migration policy effectiveness on one hand and the still limited empirical evidence on this issue on the other.
本文概述了DEMIG POLICY的方法，这是一个新数据库，追踪了1945年至2014年间45个国家约6000项移民政策变化。文章对移民政策变化的概念进行了概念化，并介绍了用于将政策内容、政策限制程度的变化以及政策变化幅度进行操作化的编码系统。本文还讨论了DEMIG POLICY在增进我们对移民政策的性质、演变和有效性的理解方面的潜力。除了显著扩大现有移民政策数据库的地理和历史覆盖范围外，DEMIG POLICY还追踪移民政策，以克服移民研究中常见的“接收国偏见”。通过对迄今为止完成的最大的移民政策数据库的主要特征提供关键见解，本文希望提供有用的指导方针，以改进未来衡量移民政策的工作。鉴于一方面关于移民政策有效性的激烈辩论，另一方面关于这个问题的实证证据仍然有限，这种改进至关重要。
