本文探討建立一個多元迴歸模型與分量迴歸模型，並將補習細分專業科目補習和才藝補習，發現補習專業科目對所有學生均有正面的效果，且有邊際報酬遞減的現象。再考慮才藝補習後得到現今多元入學方案對子女成績有正面幫助；然而，在較精緻的分量迴歸中將學生分成不同程度後可以得到多元入學方案只對部分學生才有顯著幫助，但卻導致高程度學生間的升學壓力更沉重。Coleman認為人力資本的形成和社會資本密不可分，故本文以參與社團活動情況作為依據，發現參與社團活動對子女成績有顯著負面效果，因為社會資本轉換成人力資本需要花較長的時間，且樣本為國中生可能因為升學壓力較容易放棄累積社會資本的機會，較難以將社會資本轉換成人力資本。;We constructed an OLS and quantile regression in this paper. Let after-school program subdivided into the shadow education and the talent classes. We found that for all students the shadow education had positive effects and followed the law of diminishing marginal returns. After considering the talent classes, multiple entrance program had positive effects on children grades. However if the students are subdivided into different degrees in quantile regression, we found that multiple entrance program only had effects on part of students, which would result in higher academic pressure on the talented students. Moreover, Coleman considered that social capital is part of the human capital, if we considered the factor of whether students joined the club or not, we found that it had negative effects on children’s grades. Because it took a long time to transform social capital into human capital. The junior students might face the competition for school admission, so they may give up the opportunity of accumulated social capital easily.
