Abstract：In order to achieve the goal of low-cost municipal solid waste (MSW) management and provide decision-making basis for MSW fees, subsidies and franchise management, this paper adopts the literature research method to calculate and evaluate the social cost of MSW in Beijing on the premise of source classification, and realize the monetization accounting of the full impact of the government (and residents) in all links of the life cycle of MSW. The results show that it is feasible to evaluate the social cost of MSW, and all costs are comparable in the whole life cycle. The social cost of MSW in Beijing is about 9.8 billion yuan, accounting for about 0.24% of GDP, and the social cost per unit of MSW is 1254 yuan/t; The unit social cost of other waste is the highest at 1487 yuan/t, followed by food waste at 710 yuan/t and recyclables at 389 yuan/t. The cost of human health loss caused by dangerous air pollutants emitted by other waste incineration is the main reason for the high cost of other waste. Beijing should continue to increase subsidies for the resource utilization of recyclables and food waste to reduce the amount of other waste disposal and reduce social costs through optimized management.
