Abstract: [Objective] To analyze the effects of grassland ecological reward policy on total factor productivity （TFP） in animal husbandry of six main pastoral provinces and autonomous regions, and to compare the implement effects of first and second round grassland ecological reward policy. [Method] The animal husbandry data of six main pastoral provinces and autonomous regions from the year of 2007 to 2018 were used to calculate their corresponding TFP, and the effects of two rounds′ grassland ecological reward policy on TFP in animal husbandry of six main pastoral provinces and autonomous regions were analyzed, respectively; difference-in-difference model was used to evaluate and compare the implement effects of the first and second round grassland ecological reward policy. [Result] The grassland ecological reward policy had promotive effects on TFP in animal husbandry, and the TFP in animal husbandry was 0.101 and 0.137 increased through the implement of the first and second round grassland ecological reward policy, respectively. [Conclusion] While the grassland ecological reward policy is implemented by restricting grazing and controlling livestock population, it does not impede the development of animal husbandry; the second round grassland ecological reward policy has better implement effects in comparison with the first round.
