目前,我国城市水效现状为:生产水效显著提升,生活水效基本不变,不同城市间的水效差异非常显著。本文依据环境政策分析的一般模式,对我国城市水效管理政策展开评估,结果表明:水效管理政策体系不完善;水价对于提高城市水效的作用并不十分明显;水效管理存在机构设置不明确、水效数据信息缺乏、资金供给来源不统一、“目标考核”缺乏边际节水潜力考虑和惩罚机制缺失等问题。建议构建基于水效管理目标的城市水资源管理框架,加快完善城市水效管理法律法规,逐步完善水价制定机制,实施城市水效标杆管理机制。
At present, the current situation of urban water efficiency in our country is as follows: the water efficiency of production is significantly improved, the life water efficiency is basically unchanged, and the water efficiency difference among different cities is very significant. Based on the general model of environmental policy analysis, this paper evaluates the urban water efficiency management policies in our country. The results show that: the water efficiency management policy system is not perfect; the role of water price in improving urban water efficiency is not obvious; Clearly, the lack of water efficiency data, the sources of funding are not unified, “target assessment ” lack of consideration of potential marginal water saving and lack of punishment mechanism. It is suggested to construct the urban water resources management framework based on the goal of water efficiency management, speed up the improvement of urban water management laws and regulations, gradually perfect the water pricing mechanism and implement the urban water efficiency benchmarking mechanism.
