正所謂「股市是經濟的櫥窗」，股市波動是金融變動的風向球，而金融變動則是一國經濟活動的重要指標。本研究發現，政治安定是經濟持續發展的重要前提，像台灣有安全顧慮、對外經貿依存度又極高的國家，抗壓性與耐壓自屬脆弱。其次，政治的不確定性使國內投資環境惡化，降低了國際投資性資金來台投資的意願，使得台股的交易動能明顯受限，政治面影響經濟發展，進而壓抑股市表現。由於台灣股市為淺碟型，經常受外來事件影響，漲跌起幅甚劇。國安基金設立的目的為：因應國內外重大事件，以維持資本市場及其他金融市場穩定，確保國家安定，特設置國家金融安定基金。當股市崩跌或買氣低迷不振時，台灣投資者雖往往寄望於國安基金的護盤效應，其實質成效仍有賴深入觀察檢視。

The stock market is a window to the economy. Market fluctuations herald financial change and the latter serves as an important index of state economic activity. The thesis finds that economic stability is the precondition of political stability. Security concerns and high dependence on foreign trade make Taiwan particularly vulnerable. Moreover, uncertainties in the political environment are unfavorable for both domestic and foreign investment. In short, it is clear that the stock market is affected by political factors in Taiwan. There are several aims to the establishment of national stabilization fund: to respond to both major internal and external events; to maintain stability in capital and other financial markets; and to stabilize the state. When the stock market take a particularly deep dive or when the market remains cool, it is common for Taiwan’s investors to call on the national stabilization fund to stabilize the market. Hence this author seeks to understand the effects of the national stabilization fund on the stock market.
