Abstract:

The incentive mechanism of government's cost- sharing policy for green car rental companies is researched with the assumptions that the demand is uncertain and depended on the promotion efforts. The optimal decisions of fleet sizing and promotion effort level under the no government incentive policy, the centralized decision considering environmental benefits of government and the cost sharing policy provided by government are researched respectively, and a comparative analysis is carried out. The following results is attained: the system can't achieve system optimal under the no government incentive policy; the introduced combined contract of cost sharing can not only achieve system benefit maximization but also make the members of the system achieve Pareto improvement when the contract parameters satisfy certain conditions. Finally, the example analysis is employed to discuss the cost sharing coefficient’s influence on the government and the green car rental enterprise revenue.
