利用经改进的柯布-道格拉斯生产函数,对河南省水土资源阻尼进行研究.结果表明,(1)1996-2015年河南水土资源对经济增长的阻尼系数达1.35%,其中水资源阻尼系数0.24%,土地资源阻尼系数1.11%,土地资源是制约河南省经济增长的首要因素.(2)水土资源对河南省经济的约束较中国其他省份大;虽然技术进步和资本积累可在一定时期内缓解资源约束,但长期来看,资源的替代弹性越来越小,水土资源仍是制约河南省经济增长的重要因素.%This study applied amended Cobb-Douglas production function, and measured the growth drag coefficient of soil and water resources to economy in Henan Province from 1996 to 2015 by using regression analysis. The results showed:1.The growth drag coefficient of soil and water resources to economy in Henan Province was 1.35% from 1996 to 2015, and the coefficient of water was 0.24% whereas it was 1.11% of soil, so soil was the leading limited factor to economic growth in Henan;2.For Henan Province,soil and water resources were more important than other provinces in China. In a certain period of time,technological progress and substitution of capital accumulation could ease the resource constraints,but in the long term,it would get smaller of elasticity of substitution of resource, so soil and water resources are still important factors effecting economic growth of Henan Province.
