中文摘要：

借鉴Karras（2007）的实证模型，本文利用中国1988—2007年30个省、市、自治区的面板数据，对公共部门的劳动生产效率进行实证分析，结果显示：（1）中国公共部门的劳动产出弹性为0．008；（2）中国公共部门的劳动边际产出高于非公共部门；（3）中国公共部门劳动人员的显性工资存在低估。虽然中国公共部门的劳动边际产出相对于非公共部门高，但其产出弹性仍处于较低水平。本文的政策含义是：加大劳动密集型公共品供给力度，有利于提高中国整个经济的产出水平；中国非公共部门需要改变劳动力粗放投入模式，地方政府应鼓励私人部门为员工提供多元化的职业培训与技能教育，以提高其边际产出。同时，优化公务员薪酬结构，将隐性收入逐步纳入正规货币工资范围之中。

英文摘要：

Based on the theoretical model suggested by Karras （ 2007 ） , this paper estimates the productivity of public sector employment with a panel data of 30 Chinese provinces over the 1988 - 2007 period. The empirical results show that （ 1 ） the output elasticity of Chinese public employment is 0. 008 ; （2） the marginal product of public sector employment in China is higher than that of non -public sector; （3） over the past twenty years,the explicit pay of public sector employees has been underestimated. Although the marginal product of public employment is higher than that of non - public sector,its output elasticity still remains at a low value. The policy implications are evident that the enlargement of the scale of labor - intensive public goods could significantly increase the economic output given the under - provision of public goods in China. The Chinese non - public sector should change its extensive labor input practice. Local government should encourage private enterprises to offer more on -job skill training programmes to the employees and thus a higher marginal product of non - public sector will be achieved. Meanwhile, the implicit income of Chinese civil servants should be gradually included into its wage system.
