THE SPATIO-TEMPORAL COUPLING AND COORDINATION CHARACTERISTICS AND SPATIO EFFECTS OF CARBON EMISSION INTENSITY AND HIGH-QUALITY ECONOMIC DEVELOPMENT IN CHINA

From a strategic perspective, exploring the development relationship between carbon emission intensity and high-quality economic development is crucial for China to promote green, open, coordinated, innovative, and shared regional development, and to address climate change.The analysis encompasses 30 provincial-level administrative regions in China, utilizing provincial panel data spanning from 2008 to 2021, and employing methodologies such as coupling coordination degree model, and the spatial Durbin model, the research investigates the coupling coordination characteristics and spatial effects between carbon emission intensity and high-quality economic development within China.Key findings show a declining trend in carbon emission intensity and an increasing trend in high-quality economic development throughout the study period.A coupling relationship exists between the two variables, transitioning from mild imbalance to intermediate coordination over the period from 2008 to 2021.Additionally, a significant spatial effect influences the coupling coordination degree of carbon emission intensity and high-quality economic development.Influential factors such as innovation, environmental regulation, industrial structure, economic foundation, and urbanization significantly drive the coupling coordination degree within the province and its neighboring provinces.
