Towards integrated regional sustainability: Spatiotemporal dynamics and heterogeneity in the coupling coordination between energy-environment and socio-economic systems in China’s yellow river basin
摘要
Within the framework of international Sustainable Development Goals (SDGs), the coordinated development between Energy-Environment (EE) and Socio-Economic (SE) systems represents a fundamental requirement for achieving regional sustainability objectives. China’s Yellow River Basin (YRB) demonstrates significant territorial imbalances in energy consumption patterns, environmental conditions, and economic development levels. This research examines the intricate linkages between these systems through the implementation of game theory-enhanced Criteria Importance Through Intercriteria Correlation (CRITIC) and Best-Worst Method (BWM) weighting approaches combined with an advanced coupling coordination degree (CCD) framework to evaluate the temporal and spatial dynamics of EE-SE integration throughout the YRB during 2010–2020. Results demonstrate notable spatial variability in coordination configurations, characterized by continuous improvement trajectories in southeastern territories and substantial performance gaps between downstream regions compared to upstream and midstream localities. The analysis identifies critical drivers influencing coordination effectiveness: industrial emissions, energy intensity, and capital investment exhibit adverse impacts on system coupling, whereas environmental protection expenditures demonstrate beneficial influences. These discoveries establish scientific foundations for developing targeted policies that facilitate harmonious development throughout the basin.
