Abstract：The refinement and implementation of the"double carbon"policy,the construction of a clean,safe and efficient energy system is the inevitable path for the high-quality development of China's local economy.The correlation between clean energy demonstration provincial policies and carbon emissions at the county level is the core of judging the green economic development of pilot regions,and also reflects the quality of county economic construction to a certain extent.By combing the county panel data from 2000 to 2020 and using the multi-period Difference in Difference model,this paper studies the impact of clean energy demonstration provincial policies on carbon emissions from the county level perspective.The results show that:① the clean energy demonstration provincial policy can reduce the carbon emission of the pilot county area by 21.04％.② Clean energy demonstration policies reduce carbon emissions by improving enterprise scientific and technological innovation and optimizing energy consumption structure.③ The effect of clean energy model provincial policies on carbon emission reduction in counties west of Hu Huanyong Line is better than that east of Hu Huanyong Line;Compared with other regions,the Yangtze River Economic Belt region can better play the strategic goal of reducing carbon emissions.Therefore,combined with the policy requirements of clean energy demonstration provinces,it is more practical significance to enrich the relevant clean energy demonstration provincial policies according to local conditions,guided by the policy design of the county dimension.
