摘　　要：为了探究影响京津冀地区奶业效率的关键因素,分析三地奶业的发展方向,促使京津冀形成优势互补、共同发展的新发展格局,本研究采用数据包络分析法,基于2017-2022年的京津冀地区以及其他奶业强省的统计数据,对京津冀地区以及其他奶业强省的奶业效率进行了测算对比,并进一步运用DEA-Malmquist模型,对京津冀地区奶业的时序特征以及空间特征进行分析,探究近六年京津冀地区奶业的发展状况。研究表明:北京奶业综合效率、技术效率以及规模效率均达到有效,资源利用率达到了最优状态;天津奶业要素投入利用不充分,增加要素的投入将会增加该地区的奶业效率;河北省奶业规模大,技术效率低,通过提高技术进步与成母牛单产将会增加该地区的奶业效率。尽管京津冀地区的规模效率较低,但在技术进步的推动下,全要素生产率逐年上升。说明京津冀地区应发展适度的规模奶牛养殖,逐渐形成奶牛养殖产业集群,提升其规模效率,并在提升成母牛单产和促进消费的作用下,逐渐提升京津冀奶业效率。In order to explore the key factors affecting the efficiency of dairy industry in the Beijing-Tianjin-Hebei region,point out the development direction of the three places,and promote the formation of a new development pattern of complementary advantages and common development in the Beijing-Tianjin-Hebei region.Based on the statistical data of Beijing-Tianjin-Hebei region and other provinces with strong dairy industry from 2017 to 2022,the dairy industry efficiency of Beijing-Tianjin-Hebei region and other provinces with strong dairy industry was measured and compared.Furthermore,the DEA-Malmquist model was further applied to analyze the temporal and spatial characteristics of the dairy industry in Beijing-Tianjin-Hebei region.To explore the development status of dairy industry in Beijing-Tianjin-Hebei region in recent six years.The results showed that the comprehensive efficiency,technical efficiency and scale efficiency of Beijing dairy industry were all effective,and the resource utilization rate reached the optimal state.Tianjin dairy industry factor input utilization is not sufficient,increasing factor input will increase the efficiency of dairy industry in this area.The dairy industry in Hebei province is large in scale and low in technical efficiency.The efficiency of dairy industry in this area will be increased by improving the technical progress and the yield of adult cows.Despite the low scale efficiency in the Beijing-Tianjin-Hebei region,total factor productivity has increased year by year,driven by technological progress.It is suggested that the Beijing-Tianjin-Hebei region should develop moderate scale dairy farming,gradually form a dairy farming industry cluster,and improve its scale efficiency.In addition,the efficiency of dairy industry in Beijing,Tianjin and Hebei is gradually improved under the role of increasing the output of single cow and promoting consumption.
