The Research On Theory And Method Of The National Economic Evaluation For Power Project

The medium-sized projects, especially large-sized projects are related to people's livelihood, it is absolutely necessary to carry on the national economy appraisal from the national economy overall angle. But the traditional power construction projects most neglect this in the research phase. And the explicit national economy assessment method and the concrete national economy appraisal parameters are in great need. Thus, the work to explore the parameters of electric power construction projects and methods of the national economy has the vital significance.In this paper, two key factors in the evaluation of the national economy are studied. First, the estimating model of shadow prices is studied based on semi-input-output Analysis and the Input-output table 2007. An approach which uses accounting price ratios to express shadow prices is developed. Then, according to the characteristics of power construction projects we carry out the identification, definition and adjustment of cost and effect.Then the social discount rate based on project is proposed. Finally, the cogeneration power project is put as as an example.
