摘　　要：在考虑承包商环保意识的情况下,构建了一个由政府、制造商和承包商组成的建筑材料供应链,对比分析了无补贴、对承包商补贴和对制造商补贴下各利益相关方的决策及其影响因素,从政府角度研究了建筑废弃物资源化补贴政策的制定问题.研究结果表明:当政府对承包商补贴时资源化率更低,制造商利润、消费者剩余和社会福利均更高.此时制造商会通过价格机制攫取政府补贴,使得政府补贴支出增加.研究还发现,资源化成本和承包商的环保意识以不同方式影响政府和制造商的决策,因此政府在制定补贴政策促进建筑废弃物资源化之前应了解承包商的环保意识,并评估制造商的资源化成本.Considering the environmental awareness of contractors,this paper constructs a construction material supply chain consisting of the government,a manufacturer and a con-tractor,analyzes the decision-making and infuencing factors of various stakeholders under no subsidy,contractor subsidy and manufacturer subsidy,and studies the formulation of subsidy policies for construction waste recycling from the perspective of the government.The results show that:compared with subsidizing the manufacturer,when the government subsidizes the contractor,the recycling rate is lower,and the manufacturer's profit,consumer surplus and social welfare are higher.The manufacturer will use the price mechanism to grab govern-ment subsidies at this time,which will increase governmental subsidy expenditure.We also show that the recycling cost and the environmental awareness of the contractor affect the decision-making of the government and the manufacturer in different ways.Therefore,the government should analyze the contractor's environmental awareness and evaluate the man-ufacturer's recycling cost before formulating subsidy policies to promote construction waste recycling.
