我国农业节水灌溉市场非均衡研究

A Study of Market Disequilibrium for Agricultural Water-Saving Irrigation: Based on Chinese Agricultural Water Market

灌溉用水市场均衡是理想状态,非均衡是经常状态。本文首先构建节水灌溉市场均衡模型,然后再构建了农业节水灌溉市场的非均衡模型,并提出节水灌溉市场非均衡度指标以衡量非均衡程度。造成我国农业节水灌溉市场非均衡的主要原因有:国情、水质恶化、水的使用效率低、节水灌溉设施落后、节水灌溉技术落后、认识上的落后、水市场还未建立起来、缺乏激励机制等。对此,我们要努力解决农业灌溉市场的非均衡。

This article first establishes an equilibrium model of irrigation water market, then establishes two disequilibrium models of irrigation water market. It analyzes the reasons that makes the irrigation water market be disequilibrium, which are the Chinese national reality, the bad water quality, the low rate of water usage, the obsolete water- saving irrigation infrastructure, the developing water- saving irrigation technology, the wasting water habit, the shortage of water market, the shortage of mechanism encouraging water saying.
