摘　　要：合理评估建筑垃圾(CDW)资源化所带来的经济效益与社会效益对于引导CDW投资与决策具有重要意义。运用资源经济学中的压力-状态-响应(PSR)逻辑框架,对CDW资源化综合效益产生机理进行系统分析,设计建筑垃圾资源化综合效益评估模型,分析建筑垃圾管理状态、资源化再生产品供需端匹配情况和CDW管理投入产出效果。以重庆市为例,研究发现:1)CDW循环利用率在0.06~0.14之间波动,仍然以简易填埋为主;2)CDW资源化再生产品的供需比在0.1~0.25之间波动,存在较为显著的供需不匹配现象,这是CDW资源化发展的压力和动力;3)CDW管理效益-成本的比例在0.16~0.35之间波动,说明CDW管理投入与产出存在不均衡现象,这既是"经济人"特征的投资者消极参与CDW项目的原因,又刻画了利益主体对CDW管理的回应。在此基础上,从供需比和效益-成本比两个方面对CDW供给侧和需求侧进行对策讨论与研究。Reasonable evaluating the economic benefits and social welfare of construction and demolition waste(CDW)recycling contributes to CDW investments and decision-making.The formation mechanism of comprehensive benefits on CDW recycling is analyzed by applying the pressure-state-response framework from the resource economics,and the article constructed the evaluation model of comprehensive benefits on CDW recycling.The context of CDW management,supply and demand of recycled products,and the input-output effectiveness of CDW management are determined and discussed in the case of Chongqing.These findings suggest that1)the CDW recycling rate changed between0.06and0.14,which indicated that construction and demolition waste are mostly in landfill;2)the supply-demand ratio of CDW recycled products fluctuates between0.1and0.25,which suggests that the supply-demand of recycled products is a serious mismatch,and then this mismatch is the pressure and driving force of CDW recycling development;3)the benefit-cost ratio of CDW management varies between0.16and0.35,which suggests that the input-output of CDW management is a significant disproportion,and the disproportion not only conforms to the economic man of the investor who do not participate in CDW recycling,but also reflects the stakeholders'response to CDW management.Based on the previous study,the suggestion is discussed and studied on the CDW supply-demand side applying supply-demand ratio and benefit-cost ratio.
