Replication Data and Code for “De la protesta a las urnas: movilización social y voto a la izquierda radical en Europa”

This dataset contains the replication materials for the article “De la protesta a las urnas: movilización social y voto a la izquierda radical en Europa”. The study analyses the association between social mobilisation, trade union strength and the electoral performance of radical left parties in Europe. The dataset covers 35 European countries and national elections held between 2021 and 2025. The unit of analysis is the country-election. Electoral performance is measured through the aggregate vote share of radical left parties and the vote share of the main radical left party in each country. The main explanatory variables include protest frequency per 100,000 inhabitants in the two years before the election, trade union density, collective bargaining coverage and previous parliamentary representation of radical left parties. The repository includes the final dataset, the R script used to reproduce the analysis, exported model results, figures, a codebook and a README file. The script reproduces descriptive statistics, OLS models with HC3 robust standard errors, robustness checks, fractional logit models, leave-one-out tests and the figures included in the manuscript. Data sources include Parties and Elections in Europe, ParlGov, ACLED, OECD-AIAS ICTWSS, World Bank, Eurobarometer and alternative survey sources documented in the codebook.本数据集为论文《De la protesta a las urnas: movilización social y voto a la izquierda radical en Europa》的复刻研究材料。本研究旨在分析欧洲社会动员、工会实力与激进左翼政党选举表现之间的关联。数据集覆盖2021至2025年间的35个欧洲国家及其国民选举，分析单元为“国家-选举”配对。选举表现通过两项指标衡量：其一为各国激进左翼政党的总得票率，其二为各国主要激进左翼政党的得票率。核心解释变量包含选举前两年内每10万居民的抗议事件频次、工会密度、集体谈判覆盖率，以及激进左翼政党此前的议会席位占比。本数据集仓库包含最终数据集、用于复刻分析的R脚本、导出的模型结果、图表、编码手册（codebook）以及README文件。该脚本可完成描述性统计分析、采用HC3稳健标准误的普通最小二乘（OLS）模型构建、稳健性检验、分数对数模型（fractional logit models）、留一法（leave-one-out）检验，以及论文中收录的全部图表。本数据集的数据来源包括《欧洲政党与选举》（Parties and Elections in Europe）、ParlGov、武装冲突地点与事件数据项目（ACLED）、OECD-AIAS ICTWSS、世界银行、欧洲晴雨表（Eurobarometer），以及编码手册中记录的其他替代调查数据源。
