| 摘要: | 本文利用共同隨機成本邊界模型,估計台灣公股行庫與中國股份制銀行之共同成本效率,探討兩者之效率高低,並利用一階段聯立求解方法,同時估計無效率因子模型以及成本隨機函數,資料來源為Bankscope(2009)全球銀行與機構資料庫,研究期間為1993年到2008年共16年。針對台灣公股行庫13家共163個樣本,中國股份制銀行19家共221個樣本,研究結果發現,中國銀行業之成本效率再加WTO後已有大幅進步,且發現台灣在經歷亞洲金融風暴及國內外大環境問題後,造成銀行經營效率不彰,但在2002年及2003年之金融改革,致使台灣銀行業體質的強化,成本效率表現也越來越好。在無效率因子模型中發現,在亞洲金融風暴中時對台灣無效率影響為正向而顯著,而中國之金融體系仍屬封閉,故受到國際金融風暴影響較小。在2008年之全球金融海嘯中,對兩岸銀行的無效率值影響皆為反向變動,顯現出兩岸政府之施政措施,使得兩岸銀行經營未受金融海嘯的影響。 This paper applied Meta Stochastic Cost Frontier to estimate Meta Cost Efficiency between government bank in Taiwan and Jointed-stock banks in China.The study is based on Bankscope's database and the comparing samples are 13 government banks in Taiwan and 19 joint-equity banks in China.The data starts from 1993 to 2008. Total number of sample bank is 384.Results of the research shows that the cost efficiency of China's banking sector after entry into the WTO has been substantial progress.After undergoing Asian financial crisis and international environmental issues, operation of Taiwan's banks becomes more inefficient.But in 2002、 2003, a series of financial reformed by government,Cost-effective performance is getting better and better.In the inefficiency factor model, the Asian Financial Crisis' impact on Taiwan's inefficiency is positive and significant.Because China's financial system is still closed,it is less affected by the international financial crisis.In 2008, the global financial tsunami, the inefficiency of cross-strait banking are all reverse changes affect the value.Showing the two governments' policy make banks were not affect by financial tsunami. |
