教育與失業率之間關係密切。本研究瞭解各國高等教育擴充與失業率關係。本研究透過多元迴歸分析掌握影響89個國家高等教育在學率的顯著因素，接著進行高等教育在學率預測。從89個國家的推估值選出高等教育在學率超出四分之一的國家，以及不足四分之一的國家。接著本研究以過量高等教與低度高等教育群的國家與其失業率進行分析，分析發現過量高等教育的國家，其失業率嚴重，相對的，高等教育不足的國家，其失業率有可能過高，也可能偏低。上述說明，過量高等教育會提高失業率，但是高等教育量不足，不一定是如此。針對上述分析結果，本研究提出相關建議。

The correlation of education and unemployment are significant.The main purpose of this study is to analysis the correlation of over-education, under-education and the ratio of unemployment. It used Multi-Regression Analysis to find out the significant factors, and used that model’s significant factors to predict the enrollment of higher education in 89 countries. From the predicted value, it selected the 1/4 top and 1/4 down of 89 countries. That is, in this study are so called over-education group and under-education group in respectively. And our study is to analyze the correlation of the over-education, under-education and unemployment. The results showed that over-education will have higher unemployment, but under-education may be not higher unemployment. The under-education may be lower unemployment. From that finding, some suggestions were given.
