比较政治和国际政治领域的大量实证研究利用对政党和政治精英政策立场的估计来分析偏好如何影响政治决策过程的结果。在过去的十年中，数据的可用性和方法论的进步促进了从对立场和意识形态的静态、横截面观点向对不断变化的偏好和政治变革的动态、纵向视角的转变。关于哪种数据可用于纵向分析的持续争论很大一部分围绕着使用完全计算机化的政治文本内容分析与比较政府中的尺度数据集（手工编码的政党宣言的“比较宣言项目”（CMP）数据）的利弊进行比较。虽然这一讨论的很大一部分是方法论的，但我们对不同方法如何进行实证比较知之甚少。这就是我们在本文中所做的。我们将 1980 年至 2010 年间 13 个西欧国家的政党政策立场估计值与 CMP 的政党政策立场估计值与 Wordscores 得出的立场进行比较。我们的分析表明，总体而言，CMP 和 Wordscores 方法对政党在一般左右维度上的立场做出了类似的估计。然而，不同国家的一致程度差异很大，而且也随着估计所依据的政党类型和政党宣言的不同而变化。我们检查总体模式中的异常值并讨论其可能的原因。
Numerous empirical studies in comparative and international politics use estimates of policy positions of parties and political elites to analyse how preferences shape outcomes of political decision-making processes. In the past decade, data availability and methodological advances have fostered the shift from a static, cross-sectional view on positions and ideologies to a dynamic, longitudinal perspective on changing preferences and political change. A large part of the ongoing debate on what kind of data can be used for longitudinal analysis revolves around the pros and cons of using fully computerized content analysis of political texts as compared to the yardstick dataset in comparative government, the ‘Comparative Manifesto Project’ (CMP) data of hand-coded party manifestos. While a large part of this discussion is methodological, we know little how the different methods compare empirically. This is what we do in this paper. We compare estimates of parties’ policy positions from CMP with positions derived from Wordscores for 13 Western European countries in the time period between 1980 and 2010. Our analysis shows that by and large, the CMP and the Wordscores approach produce similar estimates of parties’ positions on a general left-right dimension. Yet, the degree of congruence differs considerably over countries and also varies with the type of party and party manifesto the estimate is based on. We examine outliers from the overall pattern and discuss possible reasons for them.
