水电对于满足发展中国家的电力需求仍然是非常重要的。因此，必须调动国家资金和私人资金参与水电建设。新的水电工程不仅需要选择最低造价方案，而且还需要处理或减少与该工程有关的一些风险，以便吸引私人投资者。发展中国家政府应做的工作是怎样提高私人投资者的信心，使他们根据良好的经济前景来优先考虑向水电工程投资。 Hydropower is still very important to meet the electricity needs of developing countries. Therefore, it is necessary to mobilize state funds and private funds to participate in hydropower construction. New hydropower projects not only need to choose the lowest cost program, but also need to deal with or reduce some of the risks associated with the project in order to attract private investors. The task that governments of developing countries should do is to increase the confidence of private investors so that they can give priority to investments in hydropower projects based on sound economic prospects.
