基于随机前沿分析的贷款定价效率研究

Study on Loan Pricing Efficiency on the Basis of Stochastic Frontier Analysis

在同等条件下,高效率的贷款定价能够给银行带来更多的收益。本文将影响贷款定价的因素分成两部分:将成本因素设定为随机前沿生产函数的投入指标,将风险和其他因素设定为影响商业银行贷款定价效率的指标。通过建立商业银行贷款定价的随机前沿生产函数,研究商业银行的贷款定价效率。对中国33家商业银行2003—2012年的面板数据进行实证研究发现:大型商业银行因规模优势表现出了较高的效率;股份制银行和城市商业银行的贷款定价效率差异最大;在利率管制下,外资银行的技术优势没有体现出来。

Loan pricing of high efficiency can yield more profits for banks under the same conditions. This paper proposes that the factors influencing loan pricing are divided into two parts： the cost factors are set as the input indexes of stochastic frontier production function, risk and other factors are set as the indexes influencing loan pricing efficiency of commercial banks. By establishing the stochastic frontier production function of loan pricing for commercial banks, this paper studies the loan pricing efficiency of commercial banks. It conducts empirical research on the panel data of 33 commercial banks from 2003 to 2012, which shows that due to the scale advantage, large-scale commercial banks have higher loan pricing efficiency, and there exist great differences in loan pricing efficiency between joint- stock banks and city commercial banks, which has plenty room for advancement. Under the control of interest rates, the technical advantage of foreign banks is not reflected here.
