“重评水电的经济性”一文通篇都在为水电算帐,结果得出水电“不经济”、“要砍掉一半投资”的错误结论。原因在哪里?综观他们那个算法有两大弊病:一是采用不切实际的数据贬低水电;二是只算电能效益帐。本文对第一点不准备谈,只就丹江口的综合效益分析谈谈“重评”中存在的第二个问题。 “Review the economy of hydropower,” a text all throughout the accounts for the hydropower, the result was hydropower “not economic”, “to cut half of the investment,” the wrong conclusion.
