摘　　要：笔者基于20082017年我国30家主要商业银行的面板数据,使用随机前沿分析方法(SFA)估算出银行成本效率,通过构建动态面板模型实证研究了存款市场约束对商业银行成本效率的影响。研究发现:就存款市场数量约束看,公司定期存款比重的增加对银行成本效率并无显著影响,但公司活期存款比重的上升却有利于提高银行成本效率;个人定期和活期存款占比的增加均对银行成本效率的提升产生了积极促进作用。就存款市场价格约束看,以利息支出占比为代理变量的存款市场价格约束对银行成本效率的影响异常显著,价格约束效应明显。就不同类型银行间差异看,公司类存款比重的上升对大型商业银行成本效率无明显数量约束效应,但对股份制商业银行和城市商业银行的数量约束效应相当显著;个人类存款占比的增加对股份制商业银行成本效率不存在明显数量约束效应,但对大型商业银行和城市商业银行的数量约束效应十分突出;存款市场价格约束对大型商业银行成本效率的影响不显著,但对股份制商业银行和城市商业银行却产生了显著的价格约束效应。Based on the panel data of 30 major commercial banks in China from 2008 to 2017,this paper uses Stochastic Frontier Analysis to estimate the cost efficiency of banks,and empirically studies the impact of deposit market constraints on the cost efficiency of commercial banks The study finds that the increase of the proportion of time deposits in the deposit market has no significant effect on the cost efficiency of banks,but the increase of the proportion of current deposits in the deposit market is beneficial to the improvement of the cost efficiency of banks The increase of the proportion of individual fixed term deposits and demand deposits has played a positive role in promoting the cost efficiency of banks From the perspective of deposit market price constraints,the effect of deposit market price constraints with interest expenditure as the proxy variable on bank cost efficiency is remarkable,and the effect of price constraints is obvious In terms of the differences among different types of banks,the increase of the proportion of corporate deposits has no significant quantita tive restraint effect on the cost efficiency of large commercial banks,but has significant quantitative restraint effect on joint stock commercial banks and urban commercial banks The increase in the proportion of indivi dual deposits has no significant quantitative restraint effect on the cost efficiency of joint stock commercial banks,but has a significant quantitative restraint effect on large commercial banks and urban commercial banks The effect of deposit market price constraint on cost efficiency of large commercial banks is not signifi cant,but it has significant price constraint effect on joint stock commercial banks and urban commercial banks.
