本文以2000年至2009年計22家台灣商業銀行之追蹤資料（panel data），並利用雙因子固定效果模型（two-factor fixed-effects model）探討不同放款之成長對逾期放款比率（逾期放款/放款總額）與轉銷呆帳率（轉銷呆帳/放款總額）之影響效果。 一般而言，金融主管機關以逾期放款比率為代表銀行資產品質之指標，然而銀行或為達成業績目標，或為符合主管機關之監理要求，往往追求短期成長而忽視風險控制，在初期因放款基礎擴大反而造成逾期放款比率下降的資產品質改善假象，之後卻面臨資產品質惡化須大幅轉銷呆帳或出售不良債權而侵蝕銀行獲利及資本，因此除逾期放款比率外，本文另納入轉銷呆帳率為衡量放款品質之指標，以確實瞭解銀行信用擴張對資產品質之影響，提供金融主管機關及銀行業者在未來相關政策上之參考。 研究結果顯示，民營企業放款成長率、消費者放款成長率及資本適足率對逾期放款比率有顯著負向影響，無擔保消費者放款成長率、前期逾期放款比率及淨值比率對轉銷呆帳率有顯著正向影響，總放款成長率、中小企業放款成長率及消費者放款成長率對轉銷呆帳率有顯著負向影響。 / This paper studies 22 banks from Taiwan during the 2000-2009 period. The panel data regression is used to analyze the different loan growth influencing non-performing loan (NPL) and charge-off ratios of Taiwan’s commercial banks. In general,the authority use non-performing loan (NPL) ratio to represent the quality of bank assets.But for performance or in compliance with the authority's request,banks may pursue loan growth in the short term and ignore the risk.In the beginning, NPL ratios decrease and then banks face deterioration in assets quality.Except NPL ratio, this paper adds charge-off ratio to analyze the effect of different loan growth on assets quality. Our major findings are as follows:(1) The effects of private enterprises loan growth rate, consumer loan growth rate and capital adequacy ratio on NPL ratio are significantly negative. (2) The effects of non-residential consumer loan growth rate,NPL ratio of the previous period and equity ratio on charge-off ratio are significantly positive. (3) The effects of total loan growth rate,small and medium enterprises loan growth rate and consumer loan growth rate on charge-off ratio are significantly negative.

Στη παρούσα μελέτη, αρχικά παρουσιάζονται από θεωρητική πλευρά θέματα που αφορούν το ρυθμιστικό πλαίσιο, τον πιστωτικό κίνδυνο, τα μη εξυπηρετούμενα δάνεια και οι έννοιες Ευρωζώνη και Ευρωσύστημα. Ακολούθως, με τη χρήση ενός οικονομετρικού μοντέλου επιχειρήθηκε ο προσδιορισμός των παραγόντων εκείνων που επηρεάζουν τον δείκτη μη εξυπηρετούμενων δανείων στην Ευρωζώνη. Ο δείκτης των μη εξυπηρετούμενων δανείων ουσιαστικά συνιστάται ως προσεγγιστική μεταβλητή του πιστωτικού κινδύνου και την περίοδο αυτή της παρατεταμένης ύφεσης αποτελεί ενδεχομένως τη μεγαλύτερη απειλή που αντιμετωπίζουν τα διάφορα τραπεζικά συστήματα όλου του κόσμου. Χρησιμοποιώντας συγκεντρωτικά δεδομένα (aggregate data) σε ένα πάνελ 13 χωρών της Ευρωζώνης για την περίοδο 2000-2008 και με την βοήθεια της fixed effect προσέγγισης, εντοπίστηκαν ισχυρές συσχετίσεις μεταξύ του NPL και διαφόρων μακροοικονομικών και τραπεζικών (banκ specific) παραγόντων. Πιο συγκεκριμένα, τα ευρήματα της εμπειρικής διερεύνησης, επιβεβαιώνουν τη διεθνή βιβλιογραφία καθώς από πλευράς τραπεζικών μεταβλητών ισχυρή επίδραση στο δείκτη μη εξυπηρετούμενων δάνειων εμφανίζει ο δείκτης κεφαλαιακής επάρκειας, ο δείκτης δάνεια προς καταθέσεις και ο δείκτης των μη εξυπηρετούμενων της προηγούμενης χρονιάς. Τέλος, από μακροοικονομικής πλευράς το δημόσιο χρέος και η ανεργία φαίνεται να είναι δυο επιπλέον παράγοντες που επιδρούν στη διαμόρφωση του δείκτη, αποτυπώνοντας ότι η κατάσταση της οικονομίας των χωρών της ευρωζώνης συνδέεται άρρηκτα με τον δείκτη NPL. / In this study, from the theoretical point of you, issues regarding regulation, credit risk, non-performing loans, Eurozone and Eurosystem are presented. Then, implementing an econometric model it was examined which factors influence the ratio of nonperforming loans in the Eurozone. It is worthwhile to mention that the ratio of NPLs can be used as a proxy of credit risk. Nowadays, credit risk seems to be the greatest risk, which banking systems are facing all over the world. Particularly, Using aggregate data on a panel of 13 countries for the period 2000-2008 and applying the fixed effect approach, strong correlations between the NPL and various macroeconomic and bank specific factors are confirmed. Our findings largely agree with the literature as, in terms of bank-specific variables, the capital ratio, the loans to deposits ratio and the rate of non-performing loans of the previous year appear to exert a powerful influence on the non-performing loans rate. At the same time, from a macroeconomic perspective, the public debt and unemployment seem to be two additional factors that affect the index, revealing that the state of the economy of Eurozone countries is clearly linked to the NPL index.

Thus, we examined the relationship between concentration indicators (C3 and HHI), competition (H-statistic) and risk (NPL, Z-score) for the period comprehended between 2001 and 2013. The relationship between non-performing loans (NPL), concentration and competition was empirically tested using panel data models. The results indicates that bank concentration has a significant impact on the NPL, suggesting that more concentrated systems are more fragile. On the other hand, the results for competition and NPL indicates that a more competitive environment may generate a more stable financial system. / O presente trabalho analisou em que medida a estrutura de mercado da indústria bancária brasileira – em níveis de concentração e competição – afeta o apetite ao risco de seus agentes. Para tanto, o estudo examinou a relação entre indicadores de concentração (C3 e HHI), competição (Estatística-H) e de risco (NPL, Z-score) para o período entre 2001 e 2013. A relação entre non-performing loans (NPL), concentração e competição foi empiricamente testada através de modelos de dados em painel. Os resultados indicam que a concentração bancária tem impacto significativo no NPL, sugerindo que sistemas mais concentrados são mais frágeis. Por outro lado, os resultados para competição e NPL indicam que em ambientes mais competitivos podem gerar sistemas financeiros menos instáveis.

中國大陸自西元1979年開始實行經濟改革政策，銀行體系同時經歷了三十年的改革發展，依據中國加入世界貿易組織之承諾，其必須於2006年12月11日全面開放外資銀行登陸投資。為了面對外資銀行業可能帶來的激烈競爭與挑戰，中國政府大力支持與協助國有商業銀行進行一連串的體制改造及上市計畫，近年來中國銀行業整體的表現十分亮眼。 兩岸政府於2010年6月29日簽署之兩岸經濟合作架構協議(ECFA)，正式地為台灣的銀行業開啟通往大陸投資的一扇門，此篇論文藉由全面的研究分析中國銀行業的發展，並透過比較中國、美國及台灣具代表性的銀行在獲利能力、資產品質、流動性風險管理及新巴賽爾資本協議規定指標遵循情形等四個面向的表現，以期提供有意赴中國大陸投資之銀行業者對於當地情況有更多的概念與了解。 / After thirty years of economic and financial reforms, banking system in China has transformed from rigidly controlled to marketization nowadays with a variety of banking institutions coexist in the financial market. Among different kinds of banking institutions, large state-owned commercial banks dominate over half of total banking assets, their huge scale allow themselves to have leading positions and monopoly power in China’s banking industry. Under WTO regulations China must fully open markets for foreign banks’ investment started on December 11, 2006, before that most large state-owned commercial banks have restructured into joint-stock companies and went public sequentially in order to enhance competition for fierce challenges brought from foreign banks. Attributing to China government’s effort and support, the overall domestic banking performance has made a lot of progress in the past few years. By comparing banking performance with USA and Taiwan in four aspects of profitability, assets quality, liquidity risk management and capital adequacy ability, the study results demonstrate that general performance of banking sector and large state-owned commercial banks in China have improved greatly and even better than advanced countries in some respects. The signing of ECFA between cross-strait governments on June 29, 2010 starts a new page of Taiwan banks’ development in China, the study suggests that in the initial stage banks from Taiwan can explore markets of corporate banking by using their expertise in loans for small and medium enterprises which are always neglected by banks in China, and by providing services to Taiwan business people in China to explore markets of consumer banking, and then gradually expand market share.
