This research explores whether ¡§party identification, candidate orientation, ethnic identification and issue orientation,¡¨ the four intermediate variables of election, are correlated to the results of Taipei mayor elections in 2002 and 2006. The data in this research are mainly based on the interview broadly carried out to collect facts for ¡§the study on democratization through election¡¨ executed by Professors Huang Chi and Huang Siu-Twen in 2002 and 2005. It is with these data that this research compares the voting behavior of the voters in the two mayor elections in an attempt to find out the deviation of election for further studies. Each individual voter has of his own a variety of social backgrounds which inevitably form to some extent a connection with each of the four intermediate variables. In examination of the connection just mentioned, it is obvious that of all the voter¡¦s backgrounds the place of birth is probably the most potential and influential, and has a significant connection with each of the four factors. However, an evaluation of the connection between the voting preference and the four factors indicates that the four factors are apparently convincing in justification of the results of the second Taipei mayor election in 2006. In addition, a detailed analysis of the connections between voter¡¦s social backgrounds and his voting preference shows that the voter¡¦s place of birth plays an important role in making his voting preference. Other social backgrounds except the voter¡¦s educational level are slightly related to the voting preference in the Taipei mayor election in 2006. Based on the analysis mentioned above, it is understood that there are many variables which will influence the voting preference. Of all the intermediate variables, however, the four factors of party identification candidate orientation ethnic identification and issue orientation are perhaps most crucial and decisive. By means of the analysis and evaluation of the four factors functioning in the recent elections, it is discovered that the people here in Taiwan are relatively better educated and have made a tremendous progress in democracy. It seems that Taiwan has already developed into a nation of two-party politics.

本研究以1997年台灣縣市長選舉為標的，彙整政治學有關投票行為的相關理論，包含社會學研究途徑、社會心理學研究途徑與理性抉擇途徑的研究成果，整合該年度之總體與個體資料而設計出「特質調整模型」。特質調整模型是透過兩階段的操作模式進行預測，首先以基礎模型反應全國一致的因素，使之適用於台灣所有縣市，這些因素包括政黨認同、候選人取向與社會人口學變項。但由於各縣市狀況仍有不同，因此再進一步用延伸模型來考量各縣市的特殊選舉因素。延伸模型在基礎模型的規模上，以描述性統計來觀察選區情形後，再加入各地特質於模型之中，使其預測結果能反映各地特殊狀況。在延伸模型中，考量的因素包括議題取向、環境系絡因素、策略性投票、在位者表現、派系取向與賄選問題等。 在特質調整模型中，本研究嘗試以對數迴歸模型對各地區進行模擬計算，並用機率論的方式呈現每一位受訪者的投票可能，以反應政治學理論中的不確定性。研究結果發現基礎模型確能相當地反應出台灣各縣市的選舉狀況，描繪各地的一般狀況，而延伸模型又能更精確地貼近各地的選舉結果，反映各地的特殊選情。在資料完整的狀況下，最後各縣市的預測誤差均不超過抽樣誤差。 第一章 緒論 1 壹、研究動機與目的 1 貳、文獻檢閱 3 第二章 研究方法 25 壹、研究範圍與資料來源 25 貳、模型建構 28 參、研究架構 33 肆、模型評估 35 第三章 基礎模型 38 壹、 變數建構 38 貳、 基礎模型的探討 42 參、 討論 84 第四章 延伸模型：基礎模型的應用 87 壹、延伸模型的設計 87 貳、基隆市的延伸模型 89 參、台北縣的延伸模型 98 肆、桃園縣的延伸模型 115 伍、新竹市的延伸模型 123 陸、台中市的延伸模型 129 柒、彰化縣的延伸模型 140 捌、台南市的延伸模型 153 玖、台南縣的延伸模型 166 拾、小結 172 第五章 結論 174 壹、研究回顧 174 貳、研究效果評估 178 參、研究限制與未來研究建議 179 參考文獻 184 / This research is focused on Taiwanese county magistrates election in 1997, and based on the aggregate and individual data to design a forecasting model, named "Joined Idiosyncrasies Adjusted Model" (JIA Model). This model is operated by two stages. First, I compute a basic model, which reflects some general factors in every county. Second, I design extended models to adjust the output of basic models. Those extended models can precisely show the situation of every single county. In this model, I try to use logistic regression to compute the candidate's votes, and present the final forecast output in probability. This model made the county magistrates election more predictable, and the model errors are less than the sampling errors.
