自我控制、金融知識與不良信用貸款行為的關連性──台灣地區的驗證

SELF-CONTROL, FINANCIAL LITERACY AND HARMFUL CONSUMER CREDIT BEHAVIOR IN TAIWAN MARKET

本文透過金融監督管理委員會（金管會）2011年的國民金融知識調查資料，探討自我控制、金融知識程度與不良信用債務貸款行為之關聯性。Logit實證模型發現，具備自我控制能力與金融知識程度愈高的民眾，愈不會面臨過度信用貸款與使用信用卡預借現金的問題，代表信用管理與現今流動性管理能力較佳，而且自我控制能力與金融知識程度對民眾信用貸款行為的影響力有過之而無不及。另外，台灣民眾的性別、婚姻狀況、教育程度、家世背景與家庭年所得程度，皆為影響民眾不良信用貸款行為的重要因素。最後本文考慮選樣偏誤與內生性問題，再次確認本文研究結論相當穩健。

This paper uses Probit regression model for Third Undertaken National Financial Literacy survey in 2011 by Financial Supervisory Commission in Taiwan to examine the relationship between self-control, financial literacy and harmful consumer credit behavior. Lack self-control and financial illiteracy are positively associated with consumer over-indebtness and consumer cash advance. It means that people with lack self-control or financial illiteracy are more likely to suffer consumer credit problems. In most specifications we find a stronger role for lack of self-control than financial illiteracy in explaining consumer over-indebtness. Besides, physiological characteristics, like gender, marriage status, education level, family origin and household income, are also key factors affecting the chance to suffer consumer credit problems. Finally, our results are robustness to the potentially endogeneity and selection bias issue.
