水利水电建筑物的建设首先需要从国家整体角度出发,采用影子价格,分析计算项目所需的费用和产生的效益,考察项目对国民经济所作的净贡献,评价项目的经济合理性。本着这一原则,对河南焦作共产主义闸改建工程进行经济效益评价。 First of all, the building of water conservancy and hydropower structures needs to use the shadow price from the overall national point of view, analyze and calculate the required costs and benefits arising from the project, examine the project’s net contribution to the national economy and evaluate the economic rationality of the project. In line with this principle, economic reconstruction of Jiaozuo floodgate project in Henan Province is evaluated.
