The result shows that, the Direct Power Supply Model is inexorable selection of the whole social and economic development and the Yangtze River Power Corporation development. It also assesses one proposed strategy and finds that the active participation in price competition for networking, may help display the obvious low cost advantage of the hydropower enterprise, and the strive for direct power supply may afford more opportunity for the low cost enterprise to touch some of the end users. This not only helps to break the monopolized (currently an actually single agent) power purchase system, but also creates a policy advantage which helps the local areas to directly use the local water resources to develop large industries (for adjusting the industrial structure, increasing employment and especially for the relocation of emigrants). It also helps to develop the regional economy. Besides, this strategy will also promote the cooperation with other related enterprises, and thus promote the development of a multiple-element industry. Because the Direct Power Supply Model can make the low cost hydropower firm master partly terminal customers, then it is a normous chance for the low cost hydropower firm.

研究结果表明，直供电商业经营模式是中国整个社会经济发展和长江电力公司企业发展的必然要求和选择，在理论和实践也是切实可行的；直供电商业模式不局限于定向"电力公司"——电网购电客户，也应可约定直接向大用户，这样可以使低成本的水电公司有机会掌握部分终端客户，这除了可以打破当前实质上的单一主体的垄断购电体制外，还可以为直接利用当地水能资源、发展大工业、调整产业结构、增加就业尤其是安置移民、进而创造相当的政策性优势，进而促进区域经济发展，同时，还将有利于促进本企业与有关企业合作，发展相关多元化产业；由于直供电商业经营模式可以让低成本的水电公司掌握部分终端客户，所以对低成本的水电公司是一个巨大的机遇。
