The Taiwan banking industry is over banking. Therefore, it needs to expand overseas market to solve the dilemma. Taiwan government signed MOU and ECFA in 2009. Taiwan banks increase advantages to enter China banking industry. Recently, China banking industry is actively establishment of Country Bank. The purpose of thesis is whether Taiwan banks into Country Bank have any changes or niche. Therefore, this study is to investigate why and how foreign banks want to invest Country Bank. This paper selects good performance in the Chinese market as benchmark bank. HSBC is the benchmark bank. I study Country Bank of HSBC to find it how to strategy and management. Finally, I use Case Study to find some ways to inspire Taiwan banks. One Country Bank invested about 40 million RMB. If establishes more than ten Country Banks can use The Banks Management System. The Position is service rural areas. And the products need to innovate and satisfy rural demand.

銀行為資金融通的中介，在經濟體中佔有舉足輕重的地位。過去多使用Malmqusit 總生產力指數來衡量生產力的變化，然而Malmquist 總生產力指數雖易於分解，卻不具相乘完整性（multiplicatively complete），可能產生偏誤的情況，因此本文採用具有相乘完整性之Hicks-Moorsteen 總生產力指數，並根據O’Donnell所提出的分解方式，將生產力變動分解為技術變動、效率變動、規模效率變動與組合變動，同時總生產力指數與交易條件指數的乘積為利潤力指數，有助於了解在交易條件改變時會如何影響廠商的生產決策。 本文研究發現台灣銀行業在追求產出極大、投入極小，以提升經營績效時，卻因交易條件逐年惡化，導致利潤力呈現衰退，因此相對於總生產力，台灣銀行業的交易條件及利潤力還有待改善。生產力指數的各拆解項在2004-2005年交易條件指數大幅成長時呈現衰退，2008-2009年交易條件指數衰退時，產出技術效率指數、產出組合效率指數及殘餘組合效率指數為成長，其中產出組合效率、剩餘產出組合效率的變動與產出、投入數量有關，因此也與交易條件指數關係密切。最後根據統計檢定結果顯示Hicks-Moorsteen總生產力指數及Malmquist 總生產力指數具有顯著的差異性。

This paper emphasis on the importance of default correlation, and also illustrate how the concept is connected with the Basel Ⅱ framework’s intention. Moreover, the paper brought out the different methodologies used by practitioners to arrive at the default correlation calculation, namely, the dispute between asset correlation and equity correlation. Furthermore, based on the model proposed by Hamerle, Liebig, and Scheule (2004), a panel logit model is set up to capture the relationship between the default events and the risk components endured by the specific industry. The model is therefore used to test the applicability of such model using Taiwan’s banking industry data. The result is consistent with our expectation about including the macroeconomic variables which will help to explain the default events happened within the banking industry. But, to my surprise, the proposition about the contemporary systematic random risk effect seems to be insignificant and a fixed effect is suggested to be assumed instead.
