A RESEARCH ABOUT "GROWTH DRAG" OF CHINESE WATER-LAND RESOURCE TO ECONOMY
基于Romer模型，修正假设并加入建设用地数据，测算中国水土资源的增长阻力为每年1.18%，是美国阻力的4.92倍，但小于以往研究结果，认为资源限制对经济的影响是温和的。
According to the assumption of Romer(2001),no country can avoid the effect caused by the limitation of water and land resource,so it is strategic significance to measure the which accords with the characteristic of Chinese water and land resource for the establishment of macro-economics object.Based on the model of Romer(2001),this study modified the hypothesis of the model,and added the data of construction land into the land data,we computed the growth drag of China,i.e.1.18 percent annually,and it is 4.92 times as much as America's,and the data is smaller than the results which were computed by the scholars before.This study reviewed the following facts also,the lot of water-land resource in GDP is descending、the technology progress and the substitute elasticity of water-land resource and other factors is bigger than 1.Based on the above analysis,the study deems that the conceivable effect of restrictive water-land resource to economy is moderate at most.
