Abstract:Based on the quantitative research method of policy text,Rost Content Mining 6.0 is used to carry out quantitative research on 452 carbon emission reduction policies of animal husbandry since China’s reform and opening up. This paper analyzes the evolution process and internal logic of carbon emission reduction policy of animal husbandry in China. The results show that the carbon emission reduction policies of animal husbandry in China has experienced four stages:conceiving period,fledgling period,growing period and burgeoning period,and a carbon emission reduction policy system was gradually established integrating ecological concept,operation points and control means. Throughout the evolution process,carbon emission reduction policies show the spatial characteristics of unbalanced regional development,and the policy is still oriented to the real demand for carbon reduction. The application of policy tools has been gradually diversified,and the policy content has been increasingly specific. In the future,it is necessary to accurately identify the regional adaptability of carbon emission reduction policies,build a healthy institutional environment for carbon emission reduction,improve the socialized service system for carbon emission reduction,and improve the effectiveness of carbon emission reduction policies in animal husbandry.
