Abstract：Based on the statistical data of animal husbandry production and annual average temperature data of 33 pure animal husbandry bannersand counties in Inner Mongolia from l986 to 2O21，the time-varying DID model was used to analyze the influence of grassland property right system reform and climate change on the scale of large livestock breeding in pastoral areas. The results showed that the reform of grassland property right system had a significant positive efect on the scaleoflarge livestock breeding，of which，the household contract system of grassland had a positive efect on the scale of large livestock breeding，but the“three rights separation”reform had no significant effct on the scale of large livestock breeding.Climate change had a negative moderating efect on the relationship between property rights system and the scale of large livestock breeding. Therefore，the implementation of the reform of grassland property rights system has its positive efects，but it is necessry to further improve the policy to activate the property rights of grassland in pastoral areas and release the economic vitality of grassland animal husbandry.At the same time，strengthen long-term climate change monitoring and response，especially for the trend of annual average temperature change，and formulate corresponding animal husbandry adaptation strategies，such as the introduction of adaptable animal husbandry varieties and the improvement of breeding technology.In addition，a new pattern of coordinated development of grassland property rights system reform and climate change should be constructed to promote stable growth in the scale of large livestock farming.
