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。 Using Karras's empirical model, this paper uses the panel data of 30 provinces, municipalities and autonomous regions in China from 1988-2007 to make an empirical analysis of labor productivity in the public sector. The results show that: (1) China's public sector labor assets (2) China's public sector has higher labor marginal output than non-public sector; (3) China's public sector workers have underestimated the explicit wage. Although the output of labor in China's public sector is higher than in the non-public sector, its output elasticity is still at a low level. The policy implication of this article is: to increase the supply of labor-intensive public goods is conducive to raising the output level of China's economy as a whole; China's non-public sector needs to change the mode of extensive labor input, and local governments should encourage the private sector to provide diversified Vocational training and skills education to increase their marginal product. At the same time, we will optimize the salary structure of civil servants and gradually introduce the hidden income into the scope of formal money wages.
