註釋China's extensive and growing CO2 emissions are linked to rapid economic development and advancing urbanization, posing serious concerns in the context of climate change. Decomposition analysis has been widely performed to identify drivers of China's CO2 emissions. However, to date, no studies have examined the impacts of urbanization on CO2 emissions across all of its provinces. Using provincial statistical data and six key factors influencing CO2 emissions (carbon and energy intensity, residential consumption and consumption inhibition, and population urbanization and size), we applied the logarithmic mean Divisia index (LMDI) decomposition method to examine how urbanization affected CO2 emission changes across 30 provinces between 1990 and 2016. Our results indicated that while urbanization's impacts on CO2 emissions increased in China as a whole during this period, they were regionally differentiated. The energy intensity effect was the main driver of reduced CO2 emissions, with carbon intensity exerting weaker effects in the 30 provinces, differentiated by their energy structures. The residential consumption effect, which is strongly linked to advancing urbanization, was the primary driver of increased CO2 emissions in all of the provinces. While the consumption inhibition and population urbanization effects were positive at the national level, they were negative in highly urbanized provinces and in highly industrial provinces. These findings highlight the need to promote environmentally friendly consumption and to design regionally differentiated policies and optimized energy structures tailored to particular urbanization contexts. Moreover, they can provide valuable inputs for other developing countries undergoing continuous urbanization, contributing to efforts to balance economic development and environmental sustainability.
