中国充电桩行业创新绩效评价研究——基于博弈论组合赋权TOPSIS算法的分析

Research on Innovation Performance Evaluation of China's Charging Pile Industry——Analysis of combinatory-weighted TOPSIS algorithm based on game theory

充电桩是“新基建”七大领域之一,其对新能源产业发展和“双碳”目标实现具有重要推动作用。本文从创新投入、创新产出和创新环境支持三个方面构建充电桩行业创新绩效评价指标体系,创新性提出博弈论组合赋权TOPSIS算法,对2019-2021年17家充电桩上市公司的创新绩效进行综合评价。研究表明:充电桩行业整体创新效率有所提高,但创新绩效参差不齐且存在显著差异,表明充电桩行业创新绩效仍有较大提升空间;研发人员学历、研发投入和研发资本化率对充电桩企业创新绩效有显著影响;财政支持和税收优惠政策激发充电桩企业创新活力,提升创新绩效水平。据此,政府应继续优化财政支持政策,加大金融支持和税收优惠力度;企业要继续加大创新活动投入,尤其是核心技术研发投入。

Charging pile is one of the seven areas of“new infrastructure”,which has an important role in promoting the development of new energy industry and the realization of the“double carbon”goal.In this paper,the innovation performance evaluation index system of charging pile industry is composed of innovation input,innovation output and innovation environment support.A creative combinatory-weighted TOPSIS algorithm based on game theory is proposed to evaluate the innovation performance comprehensively of 17 charging pile listed companies from 2019 to 2021.The research shows that the overall innovation efficiency of the charging pile industry has been improved,but the innovation performance is uneven and there are significant differences,indicating that the innovation performance of the charging pile industry still has a large room for improvement;The education background of R&D personnel,R&D investment and R&D capitalization rate have significant effects on the innovation performance of charging pile enterprises;Financial support and preferential tax policies stimulate the innovation vitality of charging pile enterprises and improve the level of innovation performance.Therefore,the government should continue to optimize the fiscal support policy,increase financial support and tax incentives;Enterprises should continue to increase investment in innovation activities,especially in research and development of core technologies.
