Abstract: Considering the irreplaceable role of government in recycling Waste Electrical and Electronic Equipment (WEEE),to research the optimal cooperation mode of government and enterprise,a differential game model of government and enterprise was constructed,which had taken the government as an independent game subject to integrate into dynamic recollection system in collaboration with enterprise.In virtue of Bellman continuous dynamic programming theory,the feedback equilibrium strategy of recollecting effort,time path of environmental goodness of enterprise and overall performance of the system under three recollecting patterns that were Nash non-cooperative,cost-sharing and cooperative pattern were analyzed respectively,and the perform comparative analysis was made.The numerical example was conducted,and the sensitivity analysis to critical parameter influencing the proportion of cost determined by government was confirmed.The result showed that the environmental goodness ,economic and social performance under collaborated pattern were all better than those under other two patterns,and cost-sharing behavior of government could achieve Pareto improvement to the Nash non-cooperative scenario.
