摘要
[目的]解析草原补奖政策对6个主要草原牧区省(区)畜牧业全要素生产率(TFP)的影响,比较分析第一轮与第二轮草原补奖政策的实施效果。[方法]采用6个主要草原牧区省(区)2007-2018年的畜牧业数据计算其TFP,分析两轮草原补奖政策对6个主要草原牧区省(区)畜牧业TFP的影响;采取双重差分模型评估比较两轮草原补奖政策实施效果。[结果]草原补奖政策对畜牧业TFP有促进作用,且第一轮草原补奖政策使畜牧业TFP增加了0.101,第二轮草原补奖政策使畜牧业TFP增加了0.137。[结论]尽管草原补奖政策是通过限制放牧、减少养畜规模实施的,但并没有阻碍畜牧业的发展;第二轮草原补奖政策效果优于第一轮。
[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.
