The European Government-Opposition Voters (EGOV) Data Set

Our codes provide a tool for researchers using any part of the integrated datasets of the European Social Survey (European Social Survey Cumulative File, ESS 1-9, 2020) project to easily differentiate between respondents based on their political affiliation, dividing them into pro-government and pro-opposition groups. Individuals are coded as “government supporters”, “opposition supporters” and “non-identifiers” according to their survey response, while we excluded refusals. The database includes data for 422 985 respondents from eight data rounds between 2002 and 2020 from 33 European countries, organized all in all in 215 country-years. There are two data files attached. 1. The “European Government-Opposition Voters (EGOV) Data Set” is a comma-separated values table (.csv format file) that includes three variables. a. The variable “votedforwinner” differentiates between government voters (1), opposition voters (0) and non-voters (missing values); thus it defines the government-opposition status of European voters based on their last vote on the previous election. b. The variable “closetowinner” differentiates between government partisans (1), opposition partisans (0) and non-partisans (missing values); thus it defines the government-opposition status of European party identifiers based on their partisan attachment. c. The variable “cseqno” is a unique identification number for European Social Survey (ESS) respondents included in the integrated data sets of the ESS project. 2. The “EGOV – do file” is a do file that can be used to reproduce the content of the above table. These codes are annotated, that is, unusual changes in government composition and overlaps of elections and fieldwork periods are indicated. The European Government-Opposition Voters Data Set has been produced by using the following pieces of information coming from the (European Social Survey Cumulative File, ESS 1-9, 2020), Comparative Political Data Sets (Armingeon, Isler, Knöpfel, Weisstanner, et al., 2016) and ParlGov (Döring and Manow, 2019) data sets. - partisan preferences, that is, respondents’ vote on the last general election (164 variables, ESS) and respondents’ partisan identity (167 variables, ESS) - date of the interview (year, month, day, ESS) - date of national elections and investitures in each country-case (CPDS and ParlGov) - cabinet composition (CPDS and ParlGov) - official sites on information on national elections for clarification, if necessary

本代码为研究人员提供了一款便捷工具，可基于政治倾向对欧洲社会调查（European Social Survey Cumulative File, ESS 1-9, 2020）项目集成数据集的任意部分进行处理，将受访者划分为亲政府与亲反对党两大群体。研究对象将根据问卷作答情况被编码为"政府支持者""反对党支持者"与"无明确倾向者"三类，同时已剔除拒绝作答的样本。

本数据集涵盖2002年至2020年间8轮调查、33个欧洲国家共计422985名受访者的数据，总计覆盖215个国别年度。本次附带两份数据文件：
1. **"欧洲政府-反对党选民数据集（European Government-Opposition Voters, EGOV）"**：该文件为逗号分隔值格式（.csv格式），包含三个变量：
a. 变量`votedforwinner`：用于区分政府支持者（编码为1）、反对党支持者（编码为0）与非选民（缺失值），其基于受访者上一次大选的投票记录，定义欧洲选民的政府-反对党立场；
b. 变量`closetowinner`：用于区分政府党派支持者（编码为1）、反对党党派支持者（编码为0）与无党派倾向者（缺失值），其基于受访者的党派归属情况，明确欧洲政党支持者的政府-反对党立场；
c. 变量`cseqno`：为欧洲社会调查（ESS）项目集成数据集中纳入的受访对象的唯一识别编号。
2. **"EGOV-do文件"**：该do文件可用于复现上述数据集的完整内容。本次提供的代码带有详细注释，标注了政府组成的异常变动、选举与调研期重叠等特殊场景。

本欧洲政府-反对党选民数据集的构建，依托以下三类数据源：欧洲社会调查集成数据集（European Social Survey Cumulative File, ESS 1-9, 2020）、比较政治数据集（Comparative Political Data Sets, Armingeon、Isler、Knöpfel、Weisstanner等, 2016）以及ParlGov数据库（Döring与Manow, 2019），具体包含以下信息维度：
- 党派偏好数据：包括受访者上一次大选的投票记录（共164个变量，源自ESS）与受访者的党派身份认同（共167个变量，源自ESS）；
- 访谈日期信息：涵盖访谈的年、月、日（源自ESS）；
- 各国选举与就职日期：针对每个国别样本的全国选举与内阁就职日期（源自CPDS与ParlGov）；
- 内阁组成信息（源自CPDS与ParlGov）；
- 必要时可用于信息澄清的全国选举官方信息站点。
