绿色供应链协同创新合作策略研究

考虑供应链绿色声誉对整体收益的影响，运用微分博弈方法，研究由单一核心企业和单一配套企业组成的绿色供应链协同创新合作问题，分别考察了在不合作契约、成本分担契约和合作契约3种情形下，核心企业和配套企业的最优绿色创新投入、各自的最优收益以及绿色供应链整体的最优收益情况。通过比较分析发现：1) 成本分担契约作为激励机制，可提高配套企业绿色创新投入、双方最优收益和整体收益；2) 合作契约下的绿色供应链整体收益和参与双方的绿色创新投入达到最优。研究结论从理论层面论证绿色供应链核心企业与配套企业协同创新合作行为的有效性。

A Research on Collaborative Innovation Cooperation Strategy of Green Supply Chain

Considering the impact of green goodwill on profit of green supply chain, a study is conducted on the collaborative innovation cooperation of green supply chain composed of a single core enterprise and a single supporting enterprise with the method of differential game. To be specific, in the cases of non-cooperative contract, cost-sharing contract and cooperative contract, the optimal green innovation inputs of the core enterprise and the supporting enterprise, their respective optimal profits and the overall optimal profit of green supply chain are respectively investigated. Through a comparative analysis, it is found that: 1) as an incentive mechanism, the cost-sharing contract can improve the green innovation input of the supporting enterprise, the optimal profit of both parties and the overall profit; 2) under the cooperative contract, the overall profit of green supply chain and the green innovation input of both parties are optimized. The research conclusions provide the theoretical basis for the effective collaborative innovation cooperation between the core enterprises and the supporting enterprise in green supply chain.
