我国政府职能转变过程中的公共产品价值

Values of public goods in government functions transform

公共产品的效率等于总产出(GDP或人均GDP)除以标准公共产品效率系数的商。从1980至2005年,我国公共产品的效率与上一年相比持平和下降的总的年份占样本数的比例高达58%。对其的解释是:(1)如果财政支出的需求弹性小于其供给弹性,那么,当财政支出的用途由影响供给转变为影响需求时,公共产品的效率就会发生由提高转为下降的变化;(2)如果财政支出的公共服务职能对资本存量增加的影响程度较小,那么,当财政支出的直接生产职能转变为公共服务职能的时候,公共产品的效率就会下降。

From 1980 to 2005,the percentage of China’s public goods efficiency that remained equal to or lower than the previous year accounts for 58% among the total samples.The explanations are as follows:1) if the demand elasticity of fiscal expenditure is weaker than the elasticity of supply,the efficiency of public goods will decrease when the effect of fiscal expenditure is on need instead of on supply; 2) if the public service function of fiscal expenditure has relatively small effect on the increase of capital stock,the efficiency of public goods will descend when the direct production function turns into the public service function.
