绿色研发补贴、成本分担契约与收益共享契约研究

Research on Green R&D Subsidy, Cost-sharing and Revenue-sharing Contracts

成本分担契约与收益共享契约是提高供应链整体协调的两大工具。基于绿色消费市场背景,本文引入绿色研发补贴政策,研究成本分担契约与收益共享契约对供应链的影响。研究表明,成本分担契约与收益共享契约对政府研发补贴政策具有一定的替代作用。同时,在绿色研发补贴政策下,成本分担契约的签订并不会带来产业链整体利润水平以及社会福利水平的提升,而收益共享契约则可以实现产业链利润水平以及社会福利水平提升的目的。进一步,当契约由供应链中企业通过谈判决定时,上述结果依然成立。

With the development of economy, people’s awareness of environmental protection is increasing, which provides power for the green research and development of supply chain firms. In the supply chain green R&D, firms are affected by two aspects. On the one hand, firms within the supply chain improve the overall coordination of the green supply chain by signing cost-sharing contracts and revenue-sharing contracts;on the other hand, the government subsidizes firms’ green R&D. How does the government’s green subsidy(external influence) affect the contractual behavior of enterprises within the supply chain(internal behavior) The green R&D subsidy policy is introduced into the supply chain theory model and analyzes the above question. It is shown that cost-sharing contract and revenue-sharing contract have certain substitution effect on government R&D subsidy policy. Under the green R&D subsidy policy, will the cost-sharing contract and the revenue-sharing contract in the supply chain improve the coordination of the supply chain? It is found that the existence of cost-sharing contract will not improve the overall profit level of the industrial chain, while the revenue-sharing contract can achieve the purpose of improving the overall profit level of the supply chain. From the perspective of social welfare, revenue sharing contract can achieve the purpose of improving the level of social welfare. Furthermore, when the contractual decision is negotiated by the enterprises in the supply chain, the above results still hold.
