我国水权期权交易模式研究

当前，我国水资源危机日趋严重。实行水权交易势在必行。而水权交易模式的选择是水权交易的核心问题。传统的水权交易模式存在一定的弊端，不能实现水资源的有效配置。本文将期权理论与水权交易相结合，提出水权期权交易模式，指出该交易模式具有转移风险、价格发现、交易成本低、方便、高效、安全性强等特点，其主要作用是可以有效地规避水权价格波动产生的风险。并提出我国水权期权交易应以流域为单位，在流域内统一建立一个水权期权交易所，具体规定了水权期权交易所的职责，还指出水权期权交易的主体由水权期权交易的双方和水权期权交易所的会员共同组成。最后根据水权价格波动的特点，给出水权价格符合跳跃扩散过程的水权期权定价模型。
