河南省农业科技进步贡献率的测算和分析

本文运用改进的柯布-道格拉斯生产函数和索洛增长速度方程,对1985—2008年河南省农业科技进步对农业经济增长的贡献率进行了测算。研究结果表明,1985—2008年河南省农业科技进步对农业经济增长的贡献率达到46.47%,仅次于物资投入的贡献率,而劳动投入和土地的贡献率却很小;从经济增长发展阶段来看,"十五"期间河南省农业科技进步对农业经济增长的贡献率最大,达到55.08%,但没有呈现规律性的增长态势。

Calculation and Analysis on Contribution Rate of Agriculture Science and Technology Progress in Henan Province

This paper calculates and analyzes the contribution rate of agriculture science and technological progress in Henan province from 1985 to 2008 by the improved C-D production function and the Solow growth rate equation.The result indicates that the contribution rate of agriculture science and technology progress is up to 46.47% in Henan province during 1985-2008,which is only lower than that of material input,while the contribution rates of the input of labor and land are very minor.And the contribution rate of agriculture science and technology progress is the maximum in the Tenth Five-year Plan,which is up to 55.08%,but it doesn＇t show a regularity growth trend.
