2014年台灣發生大規模反服貿運動,又稱為太陽花運動,這個運動被認為影響了台灣人對政治的關心程度和改變政治意識型態。在太陽花運動中,Facebook 是最被廣泛利用的社群媒體,因此在本研究中,我們透過 Facebook 的公開資料來分析台灣使用者對政治感興趣的程度與政治意識形態是否有變化。我們發現這些使用者在太陽花運動過後更有可能在與政治有關的貼文按讚,且他們的政治意識型態可能也改變了。此外,我們也探討 Facebook 上「政治同溫層」的情況,發現在政治人物粉絲專頁上的使用者為相同政黨偏好的程度更高;但是太陽花運動前後這個程度沒有顯著提高。
In 2014, a large-scaled protest against the passing of the Cross-Strait Trade Agreement with China erupted in Taiwan. This movement is believed to increase the level of concern on politics and change political ideology among Taiwanese people. In this study, we address this issue empirically by analyzing Taiwanese users behaviors on Facebook, the most widely used social media platform during the movement. We first show that these users are more likely to “like” political contents after the movement. We also find that user ideology and their endorsements on politicians may change after the movement. In addition, we examined the political segregation on Facebook, and find that segregation on politician fan pages is relatively high, but we find no evidence that users became more politically segregated during that period. Our results provide some empirical evidence for an increase in political interest and change in political preference after the Sunflower movement in Taiwan.
