竞争性绿色供应链中制造商提供绿色服务的信息共享研究

doi:10.16381/j.cnki.issn1003-207x.2021.0919

Abstract

Abstract:

The information sharing of green services provided by manufacturers in two competitive green supply chains is studied. Each supply chain consists of a manufacturer that produces green products and provides free green after-sales service， and a retailer with uncertain demand information. Based on equilibrium price， product greenness and green after-sales service， a multi-stage game model under four different scenarios is constructed to analyze the value of information sharing in the supply chain. The findings are as follows： Firstly， when the manufacturer improves the green degree of products or consumers pay attention to green products， or when the investment in services is efficient or consumers care about services， the information sharing of retailers can benefit the supply chain， and can also trigger the competitive reaction of another supply chain. Secondly， manufacturers can encourage retailers to share demand information voluntarily by improving the efficiency and greenness of green services. Otherwise， manufacturers need to implement a bargaining mechanism in order to share information with retailers and achieve a win-win profit in the supply chain.

Key words: competitive supply chain, green supply chain, information sharing, green service
