环境分权下央地企协同减排策略演化——基于区块链技术应用视角

Evolution of Collaborative Emission Reduction Strategies of Central and Local Governments,Enterprises under Environmental Decentralization——Based on the Perspective of Blockchain Technology Application

环境分权下,地方政府及控排企业的机会主义行为制约着降碳目标实现,而区块链技术提供了一种可信、高效的协同减排环境。为此,本研究构建了以控排企业、地方政府和中央政府为主体的演化博弈模型,探索区块链技术投入前后的协同减排策略;并借助数值仿真研究了区块链技术的监管影响系数、应用成本及地方支出系数对系统演化路径的影响。结果显示:区块链技术投入缩短了减排系统的趋稳时间;监管影响系数与中央政府对区块链技术投入的支持程度、地方及控排企业的减排参与意愿呈正相关;区块链平台应用成本与地方政府减排参与意愿呈负相关,地方支出系数与中央政府对区块链技术投入的支持程度呈正相关,且均存在最优调控区间。因此,应积极开展区块链监管试点,引导、扶持企业绿色转型,强化中央督察职能,转变地方政府发展理念,保障减排政策落地和区域经济高质量转型。

Under environmental decentralization,the opportunistic behaviour of local governments and emission control enterprises constrains the achievement of carbon reduction targets,while blockchain technology provides a credible and efficient environment for collaborative emission reduction.To this end,we construct an evolutionary game model with emission control enterprises,local governments and the central government as the main actors,and explore the collaborative emission reduction strategies before and after the input of blockchain technology;and investigate the impact of the regulatory impact coefficient,application cost and local expenditure coefficient of blockchain technology on the evolutionary path of the system with the help of numerical simulation.The results show that blockchain technology shortens the stabilization time of the emission reduction system;the regulatory impact coefficient is positively correlated with the central government’s support for blockchain technology investment and the willingness of local governments and emission control enterprises to participate in emission reduction;the application cost of blockchain platform is negatively correlated with the local government’s willingness to participate in emission reduction,and the local expenditure coefficient is positively correlated with the central government’s support for blockchain technology investment,and both have optimal regulation interval.Therefore,blockchain regulation pilots should be actively carried out to guide and support enterprises’green transformation,strengthen the central inspection function,transform the development concept of local governments,and guarantee the implementation of emission reduction policies and high-quality transformation of regional economies.
