本文採用Bank Scope資料庫中中國銀行業的資料來估計2013-2017年城市商業銀行和全國性股份制商業銀行的共同邊界效率指數和TGR,實證結果顯示:全期間的共同邊界MCRS、MVRS和MSE以及群組生產面效率指數值GCRS、GVRS和GSE效率值顯示,城市商業銀行和全國性股份制商業銀行管理的無效率是造成全國性股份制商業銀行和城市商業銀行無效率之主要來源;全國性股份制商業銀行和城市商業銀行的TGR 顯示,城市商業銀行的TGR值相較於全國性股份制商業銀行要大,分別為0.999和0.989,即城市商業銀行的群組邊界離共同邊界的距離更小。
This paper uses the data of the Chinese banking industry in the Bank Scope database to estimate the Meta-Frontier efficiency and TGR(Technology Gap Ratio) of the national joint-stock commercial banks and city commercial bank banks from 2013 to 2017. The empirical results show that the Meta-Frontier index values MCRS, MVRS and MSE and the group production efficiency index values GCRS, GVRS and GSE show that the allocation inefficiency of national joint-stock commercial banks and city commercial banks is the main cause of inefficiency in national joint-stock commercial banks and city commercial banks. The TGR of commercial banks and city commercial banks shows that the TGR of city commercial banks is larger than that of national joint-stock commercial banks, which are 0.999 and 0.989 respectively, that is, the group boundaries of city commercial banks are smaller than national joint-stock commercial banks, to the the meta.
