社會資本理論是社會學用來解釋社會關係而建構的概念，其理論體系眾多，本研究採用Coleman社會資本的理論為架構，探討家庭為本位的社會資本與學業成就的關係。依社會資本的理論及因素分析結果，本研究將家庭社會資本界定為八個層面，五項屬於家庭內部的社會資本（父母參與、家庭規範、父母教育期待、行為監督、家庭互動），三項屬於家庭外部的社會資本（父母與學校關係、父母與鄰居關係、父母與親友關係）。本研究以國中三年級學生為對象，所使用的方法為問卷調查法，共有九百五十三位學生參與研究，研究結果證實不同社經地位學生的家庭社會資本有顯著差異，同時家庭背景及家庭結構確實會透過社會資本而影響子女的學業成就。而家庭社會資本的分層面之中，以父母教育期望、家庭互動及行為監督對學業成就的預測力較大。
