Due to the fact that the"dual carbon"policy has become an emerging issue in China in recent years,conducting a quantitative evaluation of Chinese provincial-level"dual carbon"policy text can grasp the current development overview of"dual carbon"work in various provinces.Starting from three vertical,horizontal,and individual perspectives in the policy system,this paper constructs a three-dimensional analytical framework for provincial-level"dual carbon"policies,namely"Policy responsiveness-Policy completeness-Policy synergy".The LDA topic model is used to quantify policy text,and the indicators of all dimensions are calculated by combining the theories and methods of policy diffusion,PMC model and policy synergy.Apply this framework to analyze 79 provincial"dual carbon"policy texts quantitatively.Obtain specific scores for each province's"dual carbon"policy set in three dimensions,analyze its internal reasons,provide an overall development overview,and further propose policy recommendations from four aspects:development process,policy themes,policy combinations,and policy synergy.Finally,the research limitations and prospects are summarized.
