考虑双积分政策的汽车供应链研发决策研究

Research on R&D Decision of Automobile Supply Chain Considering Double Credit Policy

为了研究积分交易价格、新能源积分比例要求、研发成本系数等因素对传统汽车制造商研发决策的影响,对三种不同研发模式下的汽车供应链进行比较分析,并通过数值仿真来验证结论,研究表明:制造商利润与积分交易价格呈负相关,当新能源车积分比例要求达到一定程度时,制造商利润与新能源车积分比例要求呈正相关;自主研发模式下的制造商利润更高,汽车研发水平更高;随着研发成本系数的减少,制造商利润逐渐提高,自主研发模式下研发成本系数对利润的敏感性更高。

In order to study the influence of points trading price,new energy points proportion requirement,R&D cost coefficient and other factors on the R&D decision-making of traditional automobile manufacturers,the automobile supply chain under three different R&D modes was compared and analyzed,and the conclusions were verified by numerical simulation.The research shows that:The manufacturer's profit is negatively correlated with the integral trading price;when the integral proportion require⁃ment of new energy vehicles reaches a certain level,the manufacturer's profit is positively correlated with the integral propor⁃tion requirement of new energy vehicles;manufacturers in the independent research and development mode have higher profits and higher level of vehicle research and development;with the decrease of R&D cost coefficient,manufacturers'profit gradu⁃ally increases,R&D cost coefficient in independent R&D mode is more sensitive to profit.
