| 目的 鼓励低碳技术创新以推动产业链的绿色转型是提升核心竞争力、发展低碳经济的重要措施,而构成产业链的核心企业与中小企业间关于低碳技术创新的协同是促进转型的关键,也是政府、投资机构等利益相关者的关注重点。方法 本文以核电产业链为例,将其中的核心企业与中小企业作为利益共同体代表产业链,并联合政府与投资机构共三方搭建演化博弈模型,在分析三方复制动态方程的基础上,得出四种可行的进化稳定策略,并通过数值模拟了不同参数对演化结果的影响。结果表明初始意愿、投资收益占比系数、协同创新收益对推动产业链协同创新具有正向影响,且投资收益占比系数、协同创新收益更具影响能力,而推广成本、投资优惠与政府的积极推广呈现倒U型关系,且投资优惠较为显著。结论 为推动产业链高效转型及促进低碳绿色产品市场的成熟提供建议。 |
| English Summary: |
| Encouraging innovation in low-carbon technologies to drive the green transformation of industrial supply chains is a crucial measure for enhancing core competitiveness and fostering a low-carbon economy. The collaborative state of low-carbon technology innovation between core enterprises and small and medium-sized enterprises (SMEs) within the supply chain is a key factor in enhancing the efficiency of this transformation. It is also a focal point of interest for government bodies, investment institutions, and other stakeholders. Taking the nuclear power industry supply chain as an example, this paper considers the core enterprises and SMEs as representatives of a common interest group within the supply chain, and collaboratively constructs an evolutionary game model involving the government, investment institutions, and the industry. Based on the analysis of the dynamic equations for these three parties, four feasible strategies for achieving evolutionary stability are identified. A numerical simulation is then conducted to examine the impact of different parameters on the evolutionary outcomes of the three parties. The results indicate that the initial intentions of the three parties, the coefficient representing the proportion of investment returns, and the benefits of collaborative innovation all have a positive impact on promoting collaborative innovation within the supply chain. Moreover, the coefficient representing the proportion of investment returns and the benefits of collaborative innovation exert a more significant influence. In contrast, the adoption costs, investment incentives, and proactive government promotion exhibit an inverted U-shaped relationship, with investment incentives being particularly pronounced. This paper aims to provide valuable recommendations for driving efficient transformation within industrial supply chains and promoting the maturity of green, low-carbon product markets to support low-carbon, green economic development. |
