本研究旨在探討人們在決定是否支持有爭議的政治政策時可能考慮的行為決策因素，包括政黨、政策認知和個人利益等。在本研究中，以台灣民眾是否支持核電作為一個爭議性的問題進行討論。研究設計了網路問卷調查，一周內共收集492份回復以進行後續統計分析。採用SPSS軟體對回復問卷數據進行OLS回歸分析，研究結果顯示，台灣民眾在面臨核能發電政策爭議時，政黨偏好和政策認知對民眾支持度有顯著影響。即使在主動操縱群體信息的實驗條件下，政黨仍然比被操縱的政黨領袖意見的影響力更大。結果還發現，人們對政策的認知或理解越多，對該政策的支持效果就越積極。就自身利益而言，研究中設計了兩種相反的自身利益利害關係下進行探討，結果顯示兩種自身利益都對政策支持沒有重大影響。這表明了台灣民眾傾向於基於理性選擇來思考，而不是只考慮自身利益，也不容易被政黨領袖的意見所操縱影響。

This study aims to explore three factors, including political party, policy cognition, and individual self-interest, that people might take as behavioral decision-making considerations for whether to support a controversial political policy or not. In the present study, whether Taiwanese people support nuclear power generation is used as a controversial issue for discussion. The online questionnaire survey was designed and a total of 492 responses were collected within one week for afterward statistical analysis. Applying SPSS software to conduct OLS regression analysis on the responses data, the research result shows that when Taiwanese people face nuclear power generation policy controversy, party preference and policy cognition have a significant influence on public support. Even under experimental conditions of active manipulation with group information, the political party remains has a greater impact than the manipulated party leader’s opinion. The result also found that if people have more cognition or understanding about the policy, the more positive effects of the supportiveness for the policy. For self-interest, it was inspected under research design with two opposing self-interest stakes, despite the result showing that both had no significant impact on policy support. This indicates that Taiwanese people tend to think based on rational choice rather than only thinking about self-interest, or not easily to be manipulated by the party leader’s opinion.
