我国综合要素生产率对经济增长贡献的实证分析

An empirical analysis on the contribution of total factor productivity to the economic growth

采用丁伯根改进的柯布-道格拉斯生产函数模型计算出我国1979~2006年间资本弹性系数α=0.409,劳动弹性系数β=0.591,进而运用索洛余值法计算得综合要素生产率对经济增长的平均的贡献率为44.43%,我国仍是粗放型的经济增长方式。必须加快自主创新能力,转变经济增长方式。

By means of J·Tinbergen improved Cobb-Dauglas Production function,we have got the result that China＇s capital elasticity coefficient α is 0.409, and labor elasticity coefficient β,0.591 1978-2006. Then using Solow＇s residual value,we know that the calculated contribution average rate of total factor productivity to the Economic Growth is 44.43%. China is still in extensive economic growth.We must accelerate the ability of independent innovation,and change the mode of economic growth.
