Abstract—We often considerthe multi-level prediction caused by uncertainty in demand in the supply chaincoordination with contracts research. However, there will be disaccord betweenthe final products and the plan, because the production process will be subjectto temperature and humidity, pests and diseases etc in the agriculturalsupply chain. We will find a best supplychain with contract which consider the producer motivation and the supply chaininterests, through the different value judgments between producers and buyersand comparing producer interests with different forms of contract.

The agricultural supply chain is unique,because it will be face the uncertainty in demand and produce. The farmerproduce is subject to temperature and humidity, pests and diseases etc uncontrollablenatural conditions, so the quantity and quality of final products will be deviatefrom the plan. So, how coordinate the action under the conditions of bidirectionaluncertainty and a number of members have become the very important subject inthe process of implementing "Contract farming" as the goal ofagricultural industrialization.

II.  Farmer Produce CirculationPattern And Supply Chain Coordination With Contracts

In our theory and practice, there arethree models of modern agricultural enterprises and farmers combined productioncollaboration, market pattern; “enterprises + farmers” pattern; integrative pattern.At the present, the agricultural enterprises recognized by the state are “enterprises+ farmers” pattern. Therefore, this paper will discuss the pattern which containscontract as the connection between enterprises and farmers.
