本文在国内首次以自然实验方法探索台湾地区大选电视辩论对两岸大学生政治态度的影响，并
引入“政治支持”这一概念来整合不同层次的变量。实验在辩论直播前后进行问卷测试以探明两岸大
学生政治支持的变化走势。研究发现，电视辩论对两岸大学生关于台湾的各项政治支持（包括特定
支持与散布性支持）存在即时显著的影响，即不仅在对台湾地区候选人、政党及投票倾向等特定支
持中出现不同程度的变化，理论上相对稳固的民主政治观念也发生了变动。这说明两岸年轻群体的
散布性支持并非十分稳固，电视辩论的短期刺激也可能对其政治观念的形塑产生一定影响。

In this study, we conducted a quasi-experiment to examine the effects of exposure to the 2012
Taiwan “presidential” debates on the attitudes of college students from Taiwan and Mainland China.
The study introduced the concept of "political support" to integrate different types of political attitudes.
College Students' political supports were tested by questionnaire before and after the debates. The
findings indicate that the debates had immediate and significant influences on the students’ support
for democratic principles. The results also show that young people’ diffuse political support would be
affected by the short-term stimulus, which means the short-term stimulus from the televised debates
probably affect the political perception of young people.
