Research On Project Benefit Evaluation System And Model Base On Circular Economy

Circular economy is the up-to-the-minute production of the research of thesustainable evelopment.It expects to change the traditional model of economic development which pays more attention on development and speed than on saving and benefits,one-sided pursuit of GDP growth,ignoringthe importance of epitomical expansion and improvement of neglect connotation.It will Change the traditional reliance on resource consumption of the linear growth of the economy into relying on the ecological resources to develop the economic.As the cycle of economic benefit evaluation of the project is not only concerned about the financial benefits of investment, but also paid more attention to projects to improve the social effects. Traditional economic theory of social costs for the project evaluation method provides the basic concepts, principles. In recent years, the economic evaluation of the theory of development is necessary to base on the characteristics of investment projects in the existing evaluation system, based on the build and improve the project evaluation index system.This paper was according to the cycle of economic theory, following the economic law, technology law, environmental law, combined with existing projects and methods of evaluation index system as the basis for project evaluation. Drawing on the project of social evaluation index system on resources, environment, energy, socio-economic evaluation of a number of indicators set up, and project evaluation of sustainable development evaluation index system, the use of the Internet and on-site investigations, screening the impact of circular economy based on the evaluation of the effectiveness of the project indicators. Choice of evaluation methods to practicality as the starting point, a trial basis fuzzy comprehensive evaluation model will be applied to the circular economy based on effective evaluation of projects. AHP to determine through the weights to a multi-level fuzzy evaluation method to conduct a comprehensive evaluation of bio-diesel project through the effective evaluation of empirical research of this method to verify the scientific validity and embodies the innovative, with practical guiding significance.
