Based on the characteristics of overreliance on fossil energy for economic growth in rich fossil fuel provinces,this paper focuses on using financial means to break the"carbon curse".This paper builds an economic growth model including green finance and carbon dioxide emissions,explains the mechanism of green finance accelerating the decoupling of energy consumption,carbon emissions and economic growth by alleviating capital price distortions,and confirms that the development of green finance should be capped at optimal capital allocation,so as to avoid the"overcapacity"in the green industry due to the excessive development of green finance.Then,by using a spatial econometric model it tests the realistic interpretation of the theoretical model.The results show that the overreliance on the energy industry in rich fossil fuel provinces of China makes these regions more inclined to the carbon intensive development,forming the phenomenon of"carbon curse".The development of green finance in rich fossil fuel provinces can strengthen the decoupling of carbon emissions and economic growth by alleviating the distortion of capital prices,thereby solving the"carbon curse"caused by the"resource curse".The development of green finance in rich fossil fuel provinces can strengthen energy decoupling and carbon decoupling in neighboring regions.The research conclusions provide useful guidance for promoting the high-quality development of green finance in an orderly manner,and provide reasonable and feasible policy ideas for solving the"car bon curse"in rich fossil fuel provinces.
