中文摘要：

从交易成本视角出发，构建了农户交易成本影响因素的结构方程模型，并设计了相应调查问卷，对我国渤海湾苹果优势区和黄土高原苹果优势区900个苹果种植样本户进行了调查，时收集到的数据运用AMOS软件进行了计算分析。研究表明农民专业合作社参与、农作物品质、农户自身因素对农户交易成本具有显著影响，区域因素对农户交易成本具有一定的影响，但是没有预期那样显著。最后，提出农民专业合作社应当在交易信息供给、高附加值农作物引进、农户交易技能培训以及组织农产品统一销售等方面实现进一步创新。

The corresponding questionnaire was designed and applied to the samples of 900 apple-planting households from the apple prepotent area of Bohai Bay Area and Loess Plateau Area, and the collected data was used for computing and analyzing by AMOS software. Our research work shows that farmers＇ specialized cooperatives participation, the quality of crops, and the farmers ＇ own factors have significant influence on farmers＇ transaction costs, and regional factors have a certain but not our expecting significant impact on farmers transaction costs. Finally, some proposals were given for the innovation of farmers＇ specialized cooperatives, such as trading information supplying, high-value crop introduction, farmers transaction skills training as well as agricultural products sales service to reduce farmers transaction costs.
