水电工程经济效益分析中的效益(以下均称经济效益)是指水电工程向电网或工农业生产用户提供电力和电量所创造的价值,亦即工农业生产总值中应该分摊给“电”所得的部分。此处,我们定义为度电(经济)效益。对此目前还没有确切的定量取值,在水电工程可行性研究中,普遍采用的是以等效最优替代工 The economic benefit analysis (hereinafter referred to as economic benefit) of hydropower project refers to the value created by the hydropower project in providing electricity and electricity to the grid or industrial and agricultural production users, that is, the gross value of industrial and agricultural output should be apportioned to the “electricity” income part. Here, we define as the electricity (economic) benefits. At present there is no exact quantitative value, in the feasibility study of hydropower projects, the commonly used is equivalent to the best alternative
