中文摘要：

以农户层面的调研数据为基础,基于两阶段数据包络分析法（DEA）,对陕西苹果种植户生产成本效率进行测度,并对影响合作社成员和非合作社成员苹果种植成本效率的因素进行分析。结果表明：该地区苹果生产成本效率有较大提升空间。同时,谈判成本对社员的苹果生产成本效率有显著的负向作用;农户的苹果种植经验和信息成本对非社员的成本效率有比较显著的正向作用,而运输成本则与非社员的成本效率负相关。

英文摘要：

A two-stage DEA method was specified to estimate apple production efficiency and to explore the determinants of cost efficiency.The data originated from a face-to-face interview of apple growers in Shaanxi province.The DEA results indicated that a large space to improve the cost efficiency of apple growers existed in Shaanxi.The second-stage estimation results revealed that the negotiation cost had negatively significant effects on cooperative member＇s cost efficiency.Meanwhile,the apple farm experience of grower and information costs had positively significant effect on the cost efficiency of non-cooperative members,whereas the transportation cost was negatively related to the cost efficiency of non-members in cooperatives.
