Abstract: 為探索選民對各種政策認同的程度,以及政策對政黨偏好與投票選擇的影響,本文利用空間投票理論來解釋2001年台灣選舉的一些情況。有別於國内多數的實證研究,本文推論出條件式勝算對數分析(Conditional Logit)是所有不連續選擇模型中,較正確地分析空間投票理論的一項工具。此外,本文也針對不相關選項的獨立性假設(Independence of Irrelevant Alternatives,IIA)作一討論。雖然IIA假設對許多選擇理論與模型是相當嚴格的條件,但經由Hausman檢定,也佐証條件式勝算對數分析結果的適當性。
This paper is to explore how the policy issues affected the voting behavior in the 2001 election based on the spatial theory of voting. It applies Conditional Logit methodology, which is more appropriate and correct than Multinomial Logit in analyzing the impact of policy on voting behavior. This paper also points out a restriction that many discrete choice models have overlooked - the property of Independence of Irrelevant Alternatives (IIA) and as a matter, introduces the Hausman Test to exam the coefficient stability.
The results show that the voting behavior is significantly different under different electoral systems. Essentially, the policy issues, including the unification-independence issue, economic policy, welfare policy, influence the voting decision more profoundly in county magistrate election, than in the legislative election. In addition, those who prefer unification with China, economic development, more social welfare, and political stability are pro KMT, PSP or NP. On the other hand, the voters who favor independent from China, environment protection, fewer social welfare, and political revolution, are pro DDP and TSU.
