研究目的：信息不对称严重阻碍农地租赁市场发育,因此研究关系网络能否助力土地流转,有利于理解土地租赁市场运行机制,并为完善制度安排提出建议。研究方法：采用logit模型和半对数模型及1050苹果种植户调研数据,研究结果：（1）与苹果经纪人经常联系有利于规避市场风险,从而助力土地流转;（2）容易获取新知识、新技术的农户倾向于流转土地;（3）维持关系网络的付出能够产生显著收益,人情支出比每增加10%,农地流转租金下降9.84%;（4）随着市场化进程的推进,关系网络助力土地流转的作用逐渐减弱;（5）关系网络通过影响交易成本助力土地流转。研究结论：（1）拓展农产品营销渠道,鼓励多种交易方式;（2）完善农业科技推广体系,提供有效的技术公共服务;（3）培育流转中介组织,因地制宜助力土地流转。

英文摘要：

Since information asymmetry seriously impedes the development of farmland rental market, the purpose of the paper is to explore whether relation network is to prompt farmland transfer or not is in favor of understanding operatation mechanism of farmland rental market and putting forward suggestions about improving system arrangement. The Methods of logit model and semi-logarithmic model are used based on the 1050 apple planters, and the results indicate： 1）Keeping in touch with apple brokers frequently can avoid market risks, which promotes farmland transfer; 2）Farmers who are able to acquire new knowledge and new technology are inclined to transfer farmland; 3）Payment for maintaining relation network can produce significant benefits, and land rent will fall 9.84% coupled with each increasing 10% of relation network expenditure ratio; 4）As the market-oriented process speeds up, the relationship between relation network and farmland transfer is gradually weakened; 5）Relation network can facilitate farmland transfer by affecting transaction costs. In conclusion, 1）Sales channels of agricultural products should be expanded, and it should encourage various transaction modes; 2）It should improve agricultural extension system, and provide effective public services of technology; 3）It should foster intermediary organization of farmland transfer, and promote farmland transfer by taking local conditions into consideration.
