城市水环境治理运作机制构建与创新

中国实行改革开放以来，工业化和城市化推动了城市经济的快速增长，但城市水环境破坏严重。政府部门曾采取一些措施来改善水环境，但并未有效解决污染问题。由于城市水环境治理问题的重要性和紧迫性，国家科技部在武汉市汉阳区启动“水专项”寻求有效的治理模式。由于采用新的制度安排，注重科学技术与管理制度的结合，明显改善了汉阳地区的水环境。“武汉水专项”的试验显示出市场机制在城市水环境治理这类公益项目中同样是有效率的。构建更加有效的城市水环境治理运作机制既是必要的，也是可能的。构建城市水环境治理运作机制的核心是在确保水环境改善的公共目标的基础上，实现城市水环境治理投入的外部效应内部化，城市水环境治理可以成为具有广阔市场和丰厚盈利的现代服务业.

NNOVATION OF OPERATION MECHANISM OF REHABILITATION OF URBAN WATER ENVIRONMENT

Since reform and opening up in China，the industrialization and urbanization have made urban economy grow fast；however，urban water environment has been destroyed seriously.In order to improve the water environment，the government has already tried some methods for mitigating water pollution，but it was difficult to find an effective one.Considering the importance and urgency of rehabilitation of urban water environment，the Ministry of Science and Technology of China issued the Restorative Project of Urban Water Environment in Hanyang，Wuhan for finding out a useful operation model.It is obvious that urban water environment in Hanyang has been improved after new regulation arrangement，especially the combination of technology and management.Market mechanism is also effective and efficient in improving urban water environment.Therefore，it is necessary and feasible to build up a new operation mechanism of rehabilitation of urban water environment，in which the key point is that to internalize the external effects of input for improving urban water environment on the base of achieving public aim.Rehabilitating urban water environment will be a modern service industry，huge marketed and profitable.
