拉丁美洲是中華民國外交友邦的重鎮，本研究以拉美地區19個國家2006-2019的14年共266筆資料為樣本，主要目的係探討該地區不同政府治理下，軍事支出對經濟成長的影響。運用集群分析將樣本資料之治理程度區分為高、低兩類。實證發現：（1）在未加入政府治理因素下，軍事支出、外國直接投資及貿易開放對該地區有顯著正向影響，而人口的成長則與經濟成長呈現無顯著負相關。（2）實證顯示高度治理國家相較於低度治理國家有顯著較高的經濟成長率。（3）高度治理國家軍事支出與經濟成長呈現顯著負向關係，而低度治理國家的軍事支出與經濟成長呈現顯著正向關係。將治理程度分為高、中及低三類進行穩健性分析，軍事支出與經濟成長的關係與兩分類一致。

Latin America is an important area for the foreign relationships of the Republic of China. This research analyzes 266 data from 19 countries in Latin America from 2006 to 2019 and aims to explore the impacts of military expenditures on economic growth under different government governance degree in this region. Cluster analysis is used to classify the governance degree of sample data into two categories: high and low. The empirical findings show that (1) Without adding government governance factors, military spending、foreign direct investment and trade openness have significantly positive impacts on the economic growth, while population growth insignificantly slows down economic growth. (2) High governance countries have significantly higher economic growth rates than countries with low governance. (3) In high governance countries, military expenditures and economic growth have a significantly negative relationship, while this relation becomes significantly positive in low governance countries. Three categories, high、medium and low , for robustness analysis, show that the relationships between military expenditure and economic growth is same with the findings of two categories.
