The Input-Output Indicator Selection in the Empirical Study of Bank Efficiency

摘要

This paper reviews the shortcomings of primary literatures in recent years about the input-output indicator selection,such as the duplication and omissions of indicators,statistical bias of the capital price's corresponding items in the financial statements,etc.According to intermediation approach as many other papers,this paper establishes three sets of input-output indicator for different aims and selects items corresponding indicator in the financial statements.The empirical study using recent 6 periods' data of all 16 Chinese listed banks shows that the DEA efficiencies evaluated by the three sets of input-output indicator are mostly consistent.
