Pricing Model for Charging Urban Domestic Garbage and Its Application
城市生活垃圾收费的定价模型及其应用

With the development of economy and industry,more and more garbage is produced in our country.However the present charge system cannot meet the need of garbage disposal,and even has become a hindrance to garbage disposal industrialization.So it is urgent to set up a new garbage charge system that can fit our current socio-economic development.Theoretically,the model of waste treatment system should be a nonlinear programming model aiming at the lowest expense, the least treatment risk and the highest overall benefit for the society,economy and environment.However,the treatment risk and the comprehensive effect cannot be quantified so easily as far as the treatment expense is concerned.An urban pricing model was proposed by combining the methods of marginal treatment expenses and expenses-sharing based on the discussion and analysis of a new-type international charge system.Taking Beijing(1998) as an example,we made an analysis using the new model.The results indicate that it is of strategic significance for controlling the recycle treatment and reducing the domestic rubbish in our country by launching the "experimental unit" for rubbish charge and setting up a perfectly categorized system.
