摘要
采用改进的三要素形式的道格拉斯C-D生产函数,在原有的劳动和资本两要素投入中加入煤炭消耗这一要素,根据处理后得到的1991—2009年的相关统计数据建立山西省生产函数模型,利用SPSS统计软件,得出各要素的产出弹性,进而计算出不同时期煤炭消耗对山西省生产总值的贡献率,分析计算结果并提出政策建议。
Adopting Douglas C-D production function with improved form of three elements, that is to add the element of coal consumption onto two original elements of the labor and the capital, this paper sets up the production function model of Shanxi Province according to the processed related statistical data of Shanxi in the period of 1991-2009, and by using statistical software SPSS, obtains the output elasticity of each element, further figures out the contribution rate of coal consumption in different periods to the total output value of Shanxi province, and makes an analysis on the results and gives some policy suggestions.
