基于GNBS和正式固定价格契约的农产品供应链关系契约模型

将GNBS和正式固定价格契约引入企业和农户的二级供应链关系契约中,比较二者作为解决争议手段时,对农户专用投资激励的不同作用,考察关系专用投资对外部市场上农产品的价值不同影响下,正式价格契约的积极作用。研究结果表明,GNBS作为解决争议机制的前提下,关系契约的自我实施的条件与农产品价值、农产品专用性、双方对剩余分配的比例有关;在特定条件下,正式固定价格契约能够强化关系契约的自我实施。

A Model of Relational Contract of Farm Produce Supply Chain Based on GNBS & Formal Fixed Price Contract

By introducing the GNBS&;formal fixed price contract into the two-stage farm produce supply chain relational contract,the paper analysed the roles of NBS&;formal price contract(as the way to deal with disputation) in inspiring the farmer's relational specific investment,and the formal price contract's roles under relational specific investment's different impacts on the product value on external markets.The results show that,when GNBS as a way of solution to the disputation,the self-enforcement condition of relational contract relates to the value of product,the specificity of the product and the share of the residual of farmer;the formal fixed price contract is contributive to the self-enforcement of relational contract under specifically condition.
