【摘要】 基于单投入多产出的随机成本前沿模型,利用我国286个城市2004~2010年的数据测算了各个城市公共支出效率,并进一步建立了基于非线性假设的城市规模、经济发展和公共支出效率的模型。主要结论如下:(1)研究期内我国286个城市政府公共支出效率平均值达74.1%,但以每年2%~5%的速度逐年下降;(2)公共支出效率与城市规模呈现倒U型曲线关系,基于公共支出效率最大化的最优城市规模是639万人;(3)公共支出效率与经济发展水平呈现U型曲线关系,随着经济发展公共支出效率由降低转为上升的临界点为人均GDP 6.42万元/年。更多还原

【Abstract】 On the basis of the stochastic cost frontier model with single input and multiple outputs,a dataset of 286 cities in China from 2004 to 2010 is employed to estimate the efficiency of public expenditure. Furthermore,based on the nonlinear assumption,the model incorporating urban size,the economic development and the efficiency of public expenditure is built to explain the efficiency. The main conclusions include:( 1) During the study period,the average efficiency of public expenditure of 286 cities reaches 74. 1%,but it gradually declines at the rate of 2-5% per year.( 2) The efficiency of public expenditure and urban size presents an inverse U-shaped curve relationship. The optimal urban size is 6. 39 million people from the view of public expenditure’s efficiency.( 3) The efficiency of public expenditure and economic development presents a U-shaped curve relationship. The turning point of GDP per capita is 64. 2 thousand yuan per year.更多还原
