基于随机边界分析的农村信用社利润效率及其影响因素研究

Study on Profit Efficiency of Rural Credit Cooperatives and Its Influencing EffectsBased on the Stochastic Frontier Analysis

本文在农村信用社利润效率及其影响因素理论分析的基础上,以陕西省81个区县的农村信用社为例,运用超越对数随机边界模型对2000-2008年农村信用社的利润效率及其影响因素进行实证研究。结果表明:不同地区农村信用社利润效率之间的差距逐年缩小,总体呈不断改进趋势;对农村信用社利润效率有显著影响的因素按影响程度从大到小依次为核心资本充足率、财政支出比重、产权制度、不良贷款率和存贷比率,除不良贷款率外其余因素的提高均对利润效率的改善起着促进作用;在此基础上从政府部门、金融监管部门和农村信用社三个层面提出相关政策建议。

On the basis of analyzing the rural credit cooperatives＇ profit efficiency and influencing effects,taking the basic situation of rural credit cooperatives from 81 counties in Shanxi province during the period between 2000 and 2008,this paper has assessed the profit efficiency and the efficiency influencing factors by the beyond logarithmic model of Stochastic Frontier Analysis.We have found that the profit efficiency gaps of the rural credit cooperatives in different regions have been narrowed during the following years,which showing continuous improvement trend.According to the degree,the profit efficiency will be significantly influenced by the core capital adequacy,aid-agriculture financial support,property right structure,bad loan ratio as well as deposit and loan rates,all factors except bad loan ratio generate promoting function.Based on the research,we have summarized the core policy suggestions of improving they profit efficiency for the government department,the supervision and the rural credit cooperatives.
