中国能源消费与二氧化碳排放双重约束下经济增长尾效研究OA

Energy serves as a cornerstone for the high-quality development of China's economy,yet environmental pollution resulting from excessive energy consumption imposes constraints on economic growth.Based on panel data from 30 provinces,municipalities,and autonomous regions in China from 2000 to 2019,and grounded in Romer's endogenous growth theory,an economic growth drag model incorporating energy consumption and CO2 emissions was constructed.By introducing spatial effects,a spatial econometric model was further established to measure the constraining intensity of energy consumption and CO2 emissions on economic growth as well as the impact of spatial spillover effects.The results showed that the economic growth of all 30 provinces,municipalities,and autonomous regions in China was constrained by energy consumption and CO2 emissions to varying degrees,with most regions,particularly in the eastern and central parts of the country,exhibiting high constraint characteristics.It was also found that omitting spatial effects would lead to an overestimation of the drag value,whereas spatial spillover effects arising from interregional factor flows could alleviate the drag constraint.Accordingly,formulating energy and environmental policies should take into account regional spatial linkages and factor mobility,with differentiated policies implemented to mitigate the constraints imposed by energy and environmental factors on economic growth.
