“双积分”政策下新能源汽车制造商激励供应商创新的契约选择研究

Contract Design to Incentive Supplier Innovation under Dual-Credit Policy

在考虑消费者技术偏好、积分交易价格和技术创新成本等多种因素影响供应链成员创新行为的基础上,分别探讨成本分担契约、收益共享契约对创新水平及供应链成员利润的影响。研究发现:成本分担比例和收益共享比例分别随积分交易价格的提高而增加,供应商创新水平随积分交易价格的增加而增加,而新能源汽车销售价格随积分交易价格的增加而降低;当创新成本在一定范围内,制造商会选择成本分担契约,当创新成本较高时,虽然成本分担契约和收益供应商契约都可以实现帕累托改进,但收益共享契约下供应商创新水平和供应链成员的利润都更优。

Considering the impact of the factors such as consumer’s technology preference,point transaction price and technological innovation cost on the innovation behavior of supply chain members,the influence of cost-sharing contract and revenue-sharing contract on innovation level and supply chain member’s profit is discussed respectively.The study found that the proportion of cost-sharing and the proportion of revenue-sharing increased with the increase of the point transaction price,and the level of supplier innovation increased with the increase of the point transaction price,while the sale price of new energy vehicles(NEV)decreased with the increase of the transaction price of the points.When the cost of innovation is within a certain range,the manufacturer will choose the cost-sharing contract,and when the cost of innovation is high,although both the cost-sharing contract and the revenue-sharing contract can achieve Pareto improvement,the level of supplier innovation and the profit of supply chain members under the revenue-sharing contract are both better.
