Quantization on Social Cost of Large-Scale Construction Project Based on Emergy Analysis Method

For some of the major projects, there are always numbers of people involved and huge environmental and social impact. Traditional thinking has always been focused on the development of economic and financial evaluation of the project construction, while ignoring the social benefits of the project. Considering all aspects of society has become the new problem researchers are facing. Currently the measurement of social cost is still in an early stage. This article defines the social structure for large-scale projects’ social analysis. The social costs system is on the basis of the social components. Combined with improved Rabel J. Burdge social evaluation system, we use the feature that emergy could be a standard of various value forms, establish a quantitative system of social costs, and for some variables of social assessment we present a quantitative method. We did the empirical study of Gulei PX program by field investigation and statistical calculations. At last we come to a conclusion that Gulei PX program have social risks. The potential problems as well as the solutions are pointed out.
