内容提要本文首先将契约还原成契约安排的组合,并提出农户选择签约(或违约)与否关键在于契约安排能否满足其偏好的观点。随后,首次将选择实验法应用于对契约安排、农户偏好以及二者逻辑关系的考察。来自安徽省砀山县水果种植户及混合Logit模型的证据表明,农户对签约表现出强偏好,并且相比于龙头企业,农户更偏向于与合作社签约;向农户提供种植技术、市场信息、农资集体采购等服务难以提高农户效用。尽管如此,农户对签订契约及以上契约安排的偏好呈异质性,并且基础设施条件、果农风险偏好及家庭劳动力禀赋的差异是农户偏好异质性的重要来源。此外,“保底价+随行就市”、预付部分果品收购款的契约安排不能实现农户效用的明显改善,合同固定价格条款则会显著降低农户效用。对农户偏好及其异质性的考察能为签约双方根据农户偏好科学地设计契约条款提供借鉴。研究结论还表明,基于农户偏好及契约安排视角的分析还能就农户签约与违约的行为给出新的解读。 
AbstractThis paper firstly treats contracts as the combinations of contractual arrangements, and puts forward the point that smallholders decide to sign a contract or not depend on whether the contractual arrangements can satisfy their preferences. Then we use choice experiment to investigate contractual arrangements, smallholders’ preferences and their relationships. Based on the data collected among fruit farmers in Dangshan County, Anhui Provence, and the results of mixed logit model, we find that: There is a general preference for marketing options that involve a contract, and signing a contract with farmer cooperatives is much more preferred by smallholders to that with leading firms. Besides, offering services, such as technical assistance, market information and inputs provision cannot increase farmers’ utilities. Despite all that, farmers’ preferences for signing a contract and the arrangements mentioned above are heterogeneous since their infrastructure available, risk attitudes and labor endowments are different. Additionally, prearranging prices could impede participation of smallholders in contract transaction, yet payment in advance and protecting price do not matter. The investigation of smallholders’ preferences and their heterogeneity can provide reference for contracting parties to design contract terms according to smallholders’ preferences. Furthermore, this paper provides a new interpretation for farmers’ behavior of signing or breaking contracts.
