潛在變數的測量及其影響：2013年TEDS台灣民眾統獨立場的分析

Abstract

In this article, we focus on the measurement of Taiwanese attitudes on the independence-unification issue, and argue that, when analysts are not certain about how measurement errors influence the results of analysis, the best way is to take measurement errors into account in their analyses. Based on the methodology of generalized latent variable modeling, we treat Taiwanese attitudes on the independence-unification issue as unobserved, latent variables, which are measured by several manifest indicators, and evaluate the effect of these attitudes on party identification. Analyzing survey data from the Taiwan’s Election and Democratization Study (TEDS) project conducted in 2013, we show that, first, Taiwanese attitudes on the independence-unification issue includes three types: principled supporters of independence, conditional supporters of independence, and conditional supporters of unification. Second, as shown in most of the studies on Taiwan politics, the stronger the voters prefer unification, the more likely they lean toward pan-blue parties, and vice versa.
