摘要
伴随着互联网公益的兴起,以阿里巴巴和京东为代表的电商平台为国内公益事业的发展注入了强大的动力,但其慈善行为往往包含公益和盈利的双重动机.文章在考虑政府对平台的补贴政策和从事社会公益活动具有多周期动态变化特征的情况下,构建平台和商家的3种微分博弈模型,探讨双方开展联合公益营销的合作问题.研究表明:1)政府的补贴政策可以激励平台和商家加大对社会公益事业的投入,促使平台愿意为商家分担更多的公益成本.2)平台为商家分担公益成本在一定条件下不仅能提升商家的社会公益投入,还能实现双方利润的Pareto改善.3)政府补贴可以提升公益成本分担契约对平台和商家利润的Pareto改善效果,但平台可能会保留部分政府补贴,不会将其全部投入社会公益.4)在协同合作的公益营销情形下,平台、商家和整体的效益以消费者剩余和社会福利都是最优的.最后,通过算例分析验证了结论,以期为平台和商家联合公益营销提供理论依据和参考.
Along with the rise of Internet public welfare,e-commerce platforms represented by Alibaba and JD have injected a strong impetus into the development of Chinese public welfare.However,the public practices of platforms and merchants often contain both public welfare and profit motives.In this paper,three differential game models are constructed for platforms and merchants to discuss their cooperation question about carrying out joint cause-related marketing(CRM),considering the government’s subsidy policy for platforms and the characteristics that engaging in social welfare is multi-cycle and dynamic.Our main results are as follows:1)The government subsidies can incentivize platforms and merchants to provide more investments for social welfare,and motivate platforms to be willing to share more CRM costs for merchants.2)Under certain conditions,platforms share a certain percentage of CRM costs for merchants can not only enhance its social welfare investment,but also achieve Pareto improvement of profits for both.3)Government subsidies can improve the Pareto effect of CRM cost-sharing contracts on the profits of platforms and merchants,but platforms may retain some of the government subsidies and will not invest them all in social welfare.4)In the joint CRM case,the benefits of platforms,merchants,and the whole system as well as the consumer surplus and social welfare are all optimal.Finally,our main results are verified via numerical simulation,hoping to provide a theoretical basis and reference for the joint CRM of platforms and merchants.
