非差分法测算我国建材工业经济增长因素贡献率

Using Non-difference Method to Measure Contribution Rate of Economic Growth Elements of Chinese Building Materials Industry

在经济增长因素连续变动的假设下 ,利用Cobb -Douglas生产函数及由此导出的增长速度方程 ,不采用差分近似 ,而直接用微分式测算经济增长因素的贡献率 ,并据此对我国建材工业经济增长因素进行实证分析。

The production function of Cobb-Douglas and the function of growth speed was used to measure the economic growth elements' contribution rate with differentiation directly other than the method of difference,under the assumption that elements of economic growth continuously Then the contribution rate of the growth elements of our country's building materials industry was measured
