現金卡、信用卡的逾期放款與銀行成本效率及銀行資本之關聯性分析

A Study on the Relationship between the Cost Efficiency of Bank and Non-performing Loans of Credit and Cash Cards

指導教授 : 趙莊敏

摘要


過去文獻多在探討總問題放款【NPL】與銀行成本效率【XEFF】之關聯性,而近年來由於銀行家數過多、企業外移,導致銀行資金過剩,銀行業者漸漸將其主要放款業務轉向消費金融市場,即消費性放款業務崛起。鑑於現金卡與信用卡是近兩年銀行機構的主流業務,本研究除了用一般觀點Berger and De Young(1997)、劉郁芬(1999)及曾瓊瑩(2004)探討總逾放比與銀行效率之關聯性外,並以近期受關切的現金卡及信用卡逾放比來探討消費金融之問題放款與銀行經營效率的關聯性。本研究主要目的為探討現金卡【NPLcash】或信用卡【NPLcredit】逾期放款與銀行成本效率間發生之先後順序。首先以隨機邊界法成本函數,承襲A. N. Berger(1997)的做法挑選投入與產出變數,衡量各銀行業者的成本效率值,有效樣本銀行為本國上市上櫃34家銀行,樣本期間為93年第三季至94年第四季,再依聯立方程式探討現金卡(或信用卡)逾放比、銀行問題放款的總逾放比與銀行成本效率的關聯性(領先/落後關係),假設分別為「一、雙卡卡戶理財不當、二、雙卡業者浮濫發卡、三、雙卡業者經營不善、四、道德危機與五、運氣不佳等。 實證結果發現,在總樣本檢定中,發行信用卡的樣本銀行,有信用卡卡戶理財不當的情形發生,另外,對總樣本銀行而言,銀行業者運氣不佳假設亦成立,兩假設成立意味著,銀行逾放比升高會先於銀行成本效率下降,且信用卡逾放比的增加亦對銀行成本效率有顯著影響。在次樣本的檢定結果中,可發現成本效率較好的銀行,即使其效率水準相對較高,依舊無法閃避信用卡卡友個人理財行為所引發的高逾放比現象;效率水準較差的銀行是因為信用卡業者浮濫發卡與總發卡銀行本身運氣不佳所致;而總逾放比較高的銀行乃是因樣本銀行本身運氣不佳和信用卡卡友理財不當所導致;而總逾放較低的樣本銀行則只是信用卡卡有理財不當之行為所引發,故總逾放較低。希望藉由本研究所得到的因果(領先/落後)關係,能給予銀行業者在消金的授信決策與資產品質面作為輔助的參考依據,使得其能做出更有效的管理決策與更謹慎地看待核卡與授信過程,降低雙卡逾期放款,進一步提升銀行經營績效。

The efficiency of banks and non-performing loans are always the most important issues in the past researches. The purpose of this research is to probe into the relationship of between the Cost Efficiency of Bank and Non-performing Loans of Credit and Cash Cards. The period is from the third quarterly, 2003 to the forth quarterly, 2004 and the samples are 34 commercial banks. We use joint formulas to test five hypotheses that describe the interemporal relationship among cosumer credit nonperforming loans, cost efficiency, and financial capital. The five hypotheses are “bad credit”, “over issue cards”, “bad management”, “moral hazard”, and “bad luck”. This result of study are:(1) The total sample support the bad credit for credit card and bad luck hypotheses. (2) The data XEFF(-2) below the sample median support bad management. (3) The data NPL(-2) above the sample median support bad crdit for credit card and bad luck. (4) The data NPL(-2) below the sample median support bad crdit for credit card.
