摘要

随着中国经济的发展,能源、经济与生态环境之间的矛盾日益突出。然而,对中国能源、经济和环境矛盾系统的时空演变研究却很少。利用主成分分析(PCA)、协调度模型、非参数核密度估计(KDE)和空间相关分析等方法,对2001-2020年中国各省经济-能源-环境系统协调度进行了评价,并分析了其时空演变特征。结果表明:2001 - 2020年,各省协调度在“勉强平衡”和“较好平衡”之间变化,总体上有所改善;但高、低区域协调差距不断扩大,中等水平省份逐渐增多,分布更加均匀。2001-2020年,省际协调存在有限的空间相关性,集聚程度略有上升。此外,一些欠发达地区在2020年仍停留在“中等平衡”状态,值得关注。

Coordinated economic, energy and environment development across China from 2001 to 2020
ABSTRACT With the development of China’s economy, the contradiction between energy, economy and ecological environment is becoming more and more prominent. However, the spatial and temporal evolution of the contradiction system of energy, economy and environment all over China is rarely focused on. This study assesses the provincial coordinated degree of the economy-energy-environment system over the period of 2001–2020 and analyzes their spatial and temporal evolution using principal component analysis (PCA), a coordination degree model, non-parametric Kernel Density Estimation (KDE), and spatial correlation analysis approaches. Results show that provincial coordination degrees from 2001 to 2020 vary between ‘barely balanced’ and ‘superiorly balanced’ with an overall improvement. However, the gap between high and low regional coordination has widen, while middle-level provinces gradually increase and are distributed more evenly. Limited spatial correlation of provincial coordination exists and the clustering level slightly increases over 2001–2020. Additionally, some less-developed regions, which are still staying at the ‘intermediately balanced’ state in 2020, call for attention.
