選舉制度影響政黨體系，是廣為人知的因果推論。依此邏輯，若以政黨體系為因，以選舉制度的變化為果，即產生內生性的選制變遷理論。然而，某些研究者仍認為選制變革起於和政黨體系無關的外生因素。本文主張，選制變遷是否受到政黨體系的影響，取決於選制的種類。第一，有利大黨的多數決選制如果始終未出現一黨過半，則國會屬於多黨制，有可能因為小黨組成多數聯盟而改採比例性選制。尤其當現狀為並立式單一選區兩票制時，可能因為小黨的議席多來自政黨名單，而比代表區域主義的多數決選制更容易導致..

It is well known that electoral system shapes party system. By this logic, an endogenous explanation for changes in electoral systems should treat party system as the cause and changes as the consequence, in sharp contrast with theories attributing changes to exogenous factors that are irrelevant to party system. This paper argues that whether changes in electoral system are caused by party system depend on the type of the electoral system. First, if a majority party never emerges from a majoritarian electoral system, minor p..

新冠肺炎從2020年的年初開始席捲全球，成為當代影響全球經濟和國際政治最重要的事件，而若以染疫人口占總人口數的比率來看，民主國家在防疫的表現上並未明顯優於非民主國家的這個事實，也引起了政治制度孰優孰劣的辯論。針對這個現象，本文試圖回答「為什麼民主國家的防疫表現沒有比非民主國家來得好」以及「在什麼情況之下民主制度所擁有的優勢才能夠在防疫的表現上展現出來」這兩個問題。關於第一個問題，本文認為，由於民主國家通常全球化的程度較高，使得其在疫情初期的防堵上失去先機，再加上民主國家受限於民主的制度與..

The COVID-19 pandemic that has been sweeping the world since the early 2020 is the most important contemporary political and economic event. The fact that democracies do not outperform non-democracies in fighting the pandemic (in terms of the confirmed case percentage to their total population) aroused the debate about which kind of the political institutions is the better one. The goal of this study aims to answer the two questions about “why democracies do not outperform non-democracies in fighting COVID-19” and “when th..
