The Comparative Analysis About Different Scale Cow Farms Technical Ffficiency

Dairy industry has been the pillar industry Hohhot City, has long been regarded as necessities of life consumption, which makes Hohhot city became famous "Chinese milk",and the output of raw milk has increased year by year, but the dairy farming industry Hohhot area of the production level is relatively low, has low production efficiency the problem of low degree, scale. This not only makes the dairy production and lack of stability and adaptability to markets so as to cause fluctuations in output and prices, affect farmers’ income level, and seriously restricts the scale development Hohhot area steps forward, is imminent, improve industry dairy farming Hohhot area production efficiency,and now the area still has coexisting backyard farmers and scale aquaculture two feeding condition, therefore, research Hohhot area in different scale dairy farms producing the existing level of technical efficiency and scale efficiency has a more realistic significance.In this study, the non parametric method by using data envelope, present situation of different scale dairy farming area based on the Hohhot, the backyard farmers, small scale,scale and large-scale four feeding mode analysis of technical efficiency in the existing Hohhot area,In the foundation of analysis of technical efficiency of dairy production in the region, summarize the reasons for the size difference of technical efficiency, provide scientific evidence for formulating and arrangements for the technical efficiency of dairy cow breeding Hohhot area can provide theoretical basis and direction for future development and national policy.
