Abstract: In order to explore optimization mode and counterm easures for solving breaking contract problem of "Company&Farmer",the established static game model reveals that the basic reason of the breaking contract problem of "Company&Farmer" is market risk,and the price fluctuation interval of static "Company&Farmer" is obtained.The established contract stability model reveales that the distribution mechanism of "benefit sharing",the reduction of the transaction cost of "Company&Farmer",the strengthening restraint mechanism and the establishment of reputation mechanism are all helpful for stability and development of "Company&Farmer".Simultaneously,futures and options are introduced to optimize "Company&Farmer",and the "Company&Farmer&futures" optimization mode can solve breaking contract risk of company,but not solve breaking contractrisk of farmer;and the "Company&Farmer&options" optimization mode rest rains breaking contract behavior of farmer radically,which can avoid risk of company,lock the company's future profit,and stabilize the source of goods of agricultural product,and also solves the problem of the risk and contract breaking behavior of company.
