劳动力就业、固定资产投入与中国工业增长——基于柯布-道格拉斯生产函数的判断

对经济增长源泉进行判断是经济增长方式转型的前提。利用2009年中国分省区工业经济增长的数据,基于柯布-道格拉斯生产函数对工业增长的动力源进行判断,结果表明,中国经济增长主要依靠固定资本和劳动的投入,二者对经济增长的解释度为98%,说明我国的经济增长方式仍是外延式增长;同时,资本产出和劳动产出弹性之和为1·2,说明中国工业增长具有规模报酬递增的性质。因此,通过规模扩大促进经济增长仍应为当前经济增长方式之一,但更重要的是,在经济增长中要重视劳动的产出弹性增加,即人力资本是经济转型和增长的未来持续动力源。

Labor employment, fixed asset investment and Chinese industry growth——Judgment based on the Cobb Douglas production function

The source of economic growth is the premise of economic growth mode transformation in China.Using the 2009 Chinese economic growth provinces industrial data, results show that the Cobb - Douglas production function to judge the source of industrial growth, based on China＇s economic growth, rely mainly on fixed capital and labor inputs, the two explanations of economic growth of 98%, shows that China＇s economic growth mode is still extensive growth;at the same time, the output of the capital and the output elasticity of labor and to 1.2, that has the property of increasing returns to scale of China＇s industrial growth.Therefore, through the expansion of the scale of economic growth should remain as one of the current economic growth mode, but more importantly, in economic growth should pay attention to the output elasticity of labor increases, namely, human capital is the economic transformation and growth in the future sustainable power source.
