The energy structure transformation is of significant practical importance as it ensures energy security, accomplishes the "dual carbon" goal and realizes high-quality economic growth. In order to explore the impact exerted by energy structure transformation on the coordinated development of economic and environmental systems, this paper employs the coupled coordination degree model to measure the coupling degree of economic and environmental systems across 30 provinces in China from 2000 to 2021. Additionally, on the basis of theoretical analysis, it adopts the fixed effect model and the mediated effect model to provide a systematic explanation of the impact energy structure transformation exerts on the coordinated development of the economic and environmental systems, as well as the underlying mechanisms. The results reveal that China's structural transformation of energy consumption significantly promotes the coordinated development of the economic and environmental systems, a conclusion that remains robust even after consideration of the explanatory variable substitutions, municipality exclusion, and tail reduction. From the perspective of heterogeneity, regions with better economic development show a more obvious dividend effect of energy structural transformation on the coordinated development of the economy and the environmental system; energy structural transformation imposes a positive impact on the coordinated development of the economy and the environmental system only in regions characterized by high levels of human capital and urbanization. In terms of the mechanism of action, energy structural transformation can facilitate of industrial structure upgrading and then drive the coordinated development of economic and environmental systems. The study proposes several policy recommendations: transform the traditional fossil energy consumption mode, reduce the proportion of traditional fossil energy, introduce corresponding subsidy policies, encourage enterprises to invest in clean energy, boost investor confidence, and enhance employment quality and income level.
能源结构转型具有重要的现实意义，它可以确保能源安全、实现“双碳”目标和实现高质量的经济增长。为了探讨能源结构转型对经济和环境系统协调发展的影响，本文采用耦合协调度模型，测算了 2000-2021 年中国 30 个省份的经济和环境系统耦合度。在此基础上，基于理论分析，采用固定效应模型和中介效应模型，系统地解释了能源结构转型对经济和环境系统协调发展的影响及其作用机制。研究结果表明，中国能源消费结构的转型显著促进了经济和环境系统的协调发展，即使考虑了解释变量的替代、直辖市排除和尾减，这一结论仍然稳健。从异质性的角度来看，经济发展水平较好的地区，能源结构转型对经济与环境系统协调发展的红利效应更为明显；只有在人力资本水平和城市化水平较高的地区，能源结构转型才会对经济与环境系统的协调发展产生正向影响。从作用机制来看，能源结构转型可以促进产业结构升级，进而推动经济和环境系统的协调发展。本研究提出了几点政策建议：转变传统的化石能源消费模式，降低传统化石能源的比重，引入相应的补贴政策，鼓励企业投资清洁能源，增强投资者信心，提高就业质量和收入水平。
