摘要
以经济学理论为基础,从研究农业需水价格弹性入手,分析水价对农业需水量的影响,确定二者之间的定量关系。该文应用计量经济学的方法,通过对黄河流域不同灌区建立农业用水需求函数,得出水的需求价格弹性,并进一步研究得出了农业需水价格弹性函数。研究表明水价与需水量和需求价格弹性之间都有明显的相关关系。将以上研究成果在黄河流域农业需水分析中进行了定量的应用研究,结果显示水价调整对该流域的农业需水有明显的抑制作用。
On the basis of economics theory and by studying the price elasticity of agricultural water demand, the effects of water price on the agricultural water demand were analyzed and quantitative interrelations between them were determined. By applying the methodology of econometrics, price elasticity of the water demand was derived through construction of agricultural water demand function for various irrigation schemes. Furthermore, price elasticity function of agricultural water demand was derived. The study indicated that distinct correlation could be found between water price and water demand, and between water price and price elasticity as well. A quantitative analysis was made for agricultural water demand in Yellow River Basin by applying the achievements in the study, and the result showed that rising of water price might reduce the agricultural water demand in the river basin obviously.
