Economic Analysis For The Wind And Solar Complementary LED Lamp Lighting System

Modern industry has entered into an age of automatism and information. With the emerging of new technology, high-tech companies are emerging, but the problem of energy nervous and environment pollution is increasing seriously which influences the people's living standards improving. So, Countries all over the world are developing the alternative sources of energy. Especially many Chinese medium and small enterprises are at the elementary phase of industrial modernization. And they not only fail to use the automatic production equipments completely because of the great costs but also lack the money to apply advanced energy and environmental protection equipment. At the same time, many managers of an enterprise come from the front line of production, and they often spend most of their energy on solving some technical problems while neglecting the economic analysis, cause the project failed finally. So it is very urgent to find a simple but practical way to improve the feasibility study skills of the mangers.This essay analysises the feasibility by the project economic analysis theory to find the bottleneck question, makes the science feasibility study methods with social benefit evaluation and economic evaluation according to the actual situation and the characteristics of product and process.In order to make the analysis clear, the writer uses some simple but intuitional tools, for example, some graphs and Gunter charts etc. examples are also given to show how to make the economic analysis and evaluate the social benefit ang economic. The essay also researches the project from many angles to giving powerful technology support through the technology economics principle and financial assessment theory.Firstly, this paper introduced the background and significance of topics, analyzed the domestic and foreign research, and introduced the main contents and methods on the paper. Secondly, it discussed the theory and method of economic analysis, and further researched the economic cost-benefit analysis method and the economic cost analysis method on the application of this project. Thirdly, it introduced the Weifang Yilanda eletric co., LTD and the project of the wind and solar complementary LED lamp lighting system, gave the safeguard measures for preventing investment risk according to the specific financial assessment and the in-depth economic analysis througu the technology economics principle. Finally, on the base of Chinese environment pollution, it gave the environmental construction ideas according to the social benefit evaluation from the angle of environmental protection, and gave the paper summary of the research work.
