By analyzing the endurance of farming households of water price and the shortcoming of transaction system of farming water fight, options of farming water are deviated from water fight market, which allows farming households to evade the natural and market risks by means of purchasing call or put option contracts in order to raise the utilization ratio of water and to realize the allocation optimum.展开更多

文摘The uncertainty of natural fall results in the uncertainty of water resource, which brings difficulty in allocating farming water resource characterized by ＂more use when it is lack but less when enough＂. By analyzing the endurance of farming households of water price and the shortcoming of transaction system of farming water fight, options of farming water are deviated from water fight market, which allows farming households to evade the natural and market risks by means of purchasing call or put option contracts in order to raise the utilization ratio of water and to realize the allocation optimum.
