| 摘 要： | 应用计量经济学和多元统计分析的方法,通过对原始资料样本数据建立预处理模型,剔除水价以外的主要影响因素对农业用水量的影响,建立农业需水价格弹性分析模型,得出农业需水的价格弹性,研究表明农业水价与需水量之间存在明显的相关关系.将预处理模型和农业需水价格弹性分析模型在江苏省高扬程灌区中进行了定量的应用研究,结果显示农业水价对用水量有明显的抑制效果.

| Abstract: | By applying the method of econometrics and multi-stat-analysis, through establishing pretreatment model for the source material and sample data, eliminating the influence of other main factors except water price on the agricultural water consumption, the analytical model for price elasticity of agricultural water demand was established and the price elasticity of agricultural water de- mand was educed in this paper. The research result indicates that agricultural water price has obvious correlativity to water demand. Pretreatment model and analytical model for price elasticity of agricultural water demand were applied in high-lift irrigation area of Jiangsu Province. The application result shows that agricultural water price has obvious suppression effect to water consumption. |
