Replication Data for: Analyzing the Cross-National Comparability of Party Positions on the Socio-cultural and EU Dimensions in Europe

Using survey vignettes and scaling techniques, we estimate common socio-cultural and European integration dimensions for political parties across the member states of the European Union. Previous research shows that party placements on the economic left-right dimension are cross-nationally comparable across the EU; however, the socio-cultural dimension is more complex, with different issues forming the core of the dimension in different countries. The 2014 wave of the Chapel Hill Expert Survey included anchoring vignettes which we use as “bridge votes” to place parties from different countries on a common liberal/authoritarian dimension and a separate common scale for European integration. We estimate the dimensions using the Bayesian Aldrich-McKelvey technique. The resulting scales offer cross-nationally comparable, interval-level measures of a party’s socio-cultural and EU ideological positions.

本研究借助调查情境（survey vignettes）与量表技术，为欧盟各成员国的政党估算统一的社会文化与欧洲一体化意识形态维度。既往研究表明，欧盟范围内政党在经济左右翼维度上的立场定位具备跨国可比性；但社会文化维度更为复杂，不同国家的该维度核心议题存在差异。2014年的教堂山专家调查（Chapel Hill Expert Survey）波次包含锚定情境，我们将其作为"桥梁投票"，将不同国家的政党置于统一的自由/威权维度，以及独立的欧洲一体化通用量表之中。本研究采用贝叶斯奥尔德里奇-麦凯尔维（Bayesian Aldrich-McKelvey）方法估算上述维度。最终生成的量表可提供具备跨国可比性的定距层级测量指标，用以衡量政党的社会文化立场与欧盟意识形态取向。
