The Database of Political Institutions 2017 (DPI2017)

The Database of Political Institutions presents institutional and electoral results data such as measures of checks and balances, tenure and stability of the government, identification of party affiliation and ideology, and fragmentation of opposition and government parties in the legislature, among others. The current version of the database, which is now hosted at the IDB, expands its coverage to about 180 countries for 40 years, 1975-2017. Researchers at the World Bank Development Research Group first compiled the database in 2000 (see citation information below). It has become one of the most cited databases in comparative political economy and comparative political institutions.

政治机构数据库收录了诸如权力制衡、政府任期与稳定性、政党归属与意识形态识别，以及立法机关中反对党和政府党派碎片化等制度与选举结果数据。该数据库的最新版本，现由国际发展银行托管，其覆盖范围已扩展至约180个国家，涵盖1975年至2017年间的40年历史。世界银行发展研究组的研究人员在2000年首次编纂了该数据库（详见下方的引用信息）。该数据库已成为比较政治经济学和比较政治机构领域中最受引用的数据库之一。
