面向续航能力的新能源汽车技术创新博弈研究

A Game Research on the Technology Innovation of New Energy Automobile Oriented to Endurance

基于提升续航能力的技术创新视角，考虑新能源汽车水平差异化程度，并引入R＆D投入、技术溢出系数、技术创新成功概率等变量，构建两阶段动态博弈模型，研究了新能源汽车产业中双寡头企业的技术创新博弈竞合问题。结果表明：技术溢出水平增加和新能源汽车差异化程度减小有利于续航能力的提升；合作研发对企业更为有利，但差异化程度较大时企业不具备合作研发的积极性；随着技术溢出水平的降低和差异化程度的增加，续航能力、企业利润与社会福利都会减小，同时合作研发的优势逐渐缩小。

Based on the technological innovation perspective of improving endurance capacity, considering the degree of differ- entiation of new energy vehicles and introducing variables such as R＆D investment, this paper technology spillover and suc- cess probability of technological innovation, this paper constructs a two-stage dynamic game model to analyze the competing is- sue of technological innovation of the duopoly enterprise in the new energy automotive industry. Results show that, the in- crease of technology spillover and the decrease of differentiation of new energy vehicles are conducive to the improvement of endurance capacity. Cooperative R＆D is more favorable to the enterprises, but they do not have active R＆D cooperation when the degree of differentiation is large. With the reduction of technological spillover and the improvement of differentiation, the endurance, corporate profit and social welfare will be reduced, while the advantages of cooperative R＆D gradually narrowed.
