基于DEA方法的地方政府性债务支出效率研究

Studies on Local Government Debt Expenditure Efficiency Based on DEA Model

在DEA—Tobit两阶段分析框架下,以公共部门效率视角研究中国地方政府性债务支出效率。测算结果表明,我国地方政府性债务支出效率总体水平较高,不同省份债务支出效率差异比较大,浙江等部分省份的效率值相对最高,湖南等省份效率值相对较低。从效率测算结果也可以看出,30个样本省份中有19个省份的政府性债务处于规模报酬不变或递减阶段,表明我国大部分省份都可以通过缩小债务规模达到提高债务支出效率的目标。研究发现,GDP增长率、人口密度、城市化率和投资率等因素是造成债务支出效率差异的重要原因。结合测算结果和原因分析,本文提出了提高债务支出效率的相关政策建议,包括加强地方政府性债务的预算管理和规模控制,完善地方政府官员政绩考核制度,建立健全地方政府性债务项目管理制度等内容。

This paper studies Chinese local government debt expenditure efficiency from the perspective of public sector and under the two-stage analysis framework of DEATobit.Through Date Envelopment Analysis（DEA）it measures the technical efficiency from CRS DEA,technical efficiency from VRS DEA and scale efficiency.On this basis,it uses a limited dependent variable model-Tobit to do empirical research on the relationship between the efficiency score and its influence factors.The research shows that,the overall efficiency of Chinese local government debt expenditure is high,however the efficiency scores are quite different among local governments.The GDP growth rate,population density,urbanization rate and invest rate are the important causes of the discrepancy.
