中文摘要：

本文基于调研数据，运用随机前沿分析方法测算了不同原料奶生产模式的经济效率、技术效率和配置效率，并利用Tobit模型对影响原料奶生产效率的因素进行分析。研究结果表明，中国不同原料奶生产模式经济效率普遍较低，特别：是配置效率明显不足，这说明在不改变投入水平的条件下，奶牛养殖户（企业）可以通过改善投入要素组合提高产出水平。三种不同生产模武相比，牧场的效率最高，养殖小区次之，散户的最低。Tobit模型结果说明：农户个人特征、农户家庭或者企业特征、精粗饲料比对原奶生产效率有显著影响。

英文摘要：

Based on the survey data, we calculate the economic efficiency, the technical efficiency and the allocation efficiency of different raw milk producing patterns by using stochastic fruntier analysis method. Then we analyze the factors that determine the production efficiency by using Tobit model. The results show that all of the three patterns suffer from the low economic efficiency, while the allocation efficiency is of lowest. These results suggest there is considerable room to increase the dairy output without additional inputs, especially through choosing the optimal input proportions. Among the different raw milk pi＇oducing patterns, the pasture is enjoying the highest efficiency, and cows community is in the middle, while the individual peasants are suffering from the lowest efficiency. Tobit model＇s suggestions are as follows. The characteristics of the household head, the features of the peasant family or enterprise and the： structure of forage influence the efficiency of raw milk production too.
