Abstract: Amid the escalating challenges posed by global climate change, the imperative to mitigate carbon emissions and advance carbon neutrality has emerged as a shared goal for humanity. There exists a prevailing consensus among various sectors of society regarding the pivotal role that green technology innovation plays in tackling global climate change challenges. The magnitude of the global climate crisis has generated substantial apprehension among individuals from diverse backgrounds, leading to a heightened focus on fostering extensive collaboration in green technology innovation. Green technology innovation, as a complex engineering endeavor involving multiple stakeholders, requires the establishment of efficient collaborative mechanisms among various entities, such as government bodies, enterprises, and science and technology intermediary service organizations. Green technology innovation service platforms are widely acknowledged as essential intermediary service organizations that contribute to the advancement of green technology innovation. These platforms play a critical role in facilitating effective collaboration between enterprises involved in green technology innovation. Additionally, the government is expected to have an impact on the collaboration between these platforms and enterprises in the field of green technology innovation. The rational utilization of environmental regulatory policies by the government to promote cooperation in green technology innovation between platforms and enterprises, as well as ensuring the effectiveness of such cooperation, is an urgent issue that has received relatively limited attention. Drawing upon the framework of evolutionary game theory, this study investigates the equilibrium strategies adopted by different entities, including enterprises, platforms, and the government, within the context of cooperation in green technology innovation. This research holds significant implications for enhancing the green technology innovation cooperation system, guiding entities to optimize their behaviors, and promoting effective cooperation in green technology innovation.
This study delves into the dynamic evolution process of green technology innovation cooperation between enterprises and green technology innovation service platforms, taking into account the influence of government environmental regulations. Specifically, this study develops an evolutionary game model to investigate the impact of government environmental regulations on the collaboration of green technology innovation between enterprises and platforms. The model incorporates the government, enterprises, and green technology innovation service platforms. Two crucial technical factors, namely technology greenness and technology innovation degree, are taken into account. The utilization of the evolutionary game theory model as a theoretical framework enables a comprehensive analysis of the decision-making conduct exhibited by pivotal stakeholders engaged in collaborative efforts for green technology innovation. This especially well suits exploring the intricate interactions among the government, enterprises, and green technology innovation service platforms. Additionally, through an examination of the effects of typical technical factors on cooperation, such as technology greenness and technology innovation degree, this study seeks to advance our comprehension of the determinants that shape cooperation practices in green technology innovation. Furthermore, system dynamics techniques are employed to simulate the dynamic evolution of the cooperative system, enabling the examination of interconnections and feedback loops among the principal participants throughout the course of time.
This study presents the following findings: Firstly, in the absence of government environmental regulations, there is an increased likelihood of cooperation in green technology innovation between enterprises and green technology innovation service platforms as the level of technology greenness and technology innovation degree decreases. When technology greenness is at a low level, the speed of cooperative innovation will accelerate. Nevertheless, when technology greenness attains a specific threshold, the speed of collaborative innovation will decelerate. Secondly, the implementation of environmental regulations by the government is subject to the influence of technical factors on the cooperation for innovation in green technology. Specifically, when the comprehensive index of technology, formed by the factors of technology greenness and technology innovation degree, is low, the cooperative system will evolve into a state of stable equilibrium. However, when the comprehensive index of technology surpasses a certain threshold (ranging from 0.25 to 0.35), the evolutionary strategy of the cooperative system gradually will transition from cooperation to non-cooperation. Thirdly, in the stable equilibrium state of three-party cooperation, government environmental regulations play a critical role in shaping the cooperative system of green technology innovation. Specifically, government environmental regulations, such as green technology innovation incentives and tax preferences, have a significant impact on the willingness of enterprises and platforms to engage in collaborative efforts for green technology innovation. Furthermore, the government’s advocacy for environmental regulation policies contributes to overall social benefits, thereby serving as an additional incentive to enforce such policies and foster collaboration in the advancement of green technology innovation.
This study provides valuable insights for enterprises and green technology innovation service platforms in their decision-making process regarding green technology innovation cooperation and offers useful guidance for the government in formulating policies that aim to encourage collaboration in green technology innovation among different entities. Future research can take into account the heterogeneity of the actors involved in green technology innovation and delve deeper into the effects of factors such as regions and industries on cooperation in green technology innovation.

摘要： 如何促进绿色技术创新是全球气候变化背景下社会各界人士亟需解决的重要问题。本文构建由政府、企业和绿色技术创新服务平台三方组成的演化博弈模型,在考虑技术绿色度和技术创新度两个典型技术因素的基础上,研究政府环境规制对企业和平台间绿色技术创新合作的影响,并通过系统动力学方法对各主体的决策行为进行了仿真分析。研究表明:在政府没有实施环境规制时,绿色技术创新合作的概率随着技术绿色度和技术创新度的降低而增大,且当技术绿色度处于较低水平时,合作创新的速度先快后慢;在政府实施规制时,技术因素变化对绿色技术创新合作系统的影响存在临界值,只有当综合度小于临界值,合作系统将演化稳定于理想的均衡状态。研究结果对政府实施环境规制政策以及企业和平台的绿色技术创新决策具有一定的启示作用。
