Efficiency evaluation and countermeasure research of free-range dairy cows based on DEA-Malmquist model
Under the background of large-scale dairy cows breeding in China,the efficiency aimed at individual provinces where dairy cows are now free-range raised is evaluated in order to provide a theoretical basis for future development.Based on the relevant data of free-range dairy cows from 2012 to 2021,DEA-Malmquist model was used to calculate the efficiency of free-range dairy cows.The results show that the overall efficiency of free-range dairy cows does not reach DEA efficiency,which is mainly due to the scale efficiency.Only in the period of 2016-2017 and 2017-2018,the efficiency of free-range dairy cows has been improved,and the other periods has been decreased,especially rapidly in the pe-riod of 2018-2020.From 2012 to 2021,the efficiency of free-range dairy cows in Shanxi and Xinjiang has been increased,while that in Jilin,Hu-nan and Shaanxi has been decreased.According to the research results,the implementation of differentiated development strategies and the empha-sis on the technical training of retail farmers are the path selections for the future development of free-range dairy cows..
