摘要(Abstract)：
基于整个社会的视角,对水权交易效率进行公理化分析,为水权交易的深入研究奠定基础。首先,提出分析的假设条件,定义水权配置效率,该效率满足完备性、传递性公理。其次,定义水权边际价值、总价值,提出水权边际价值递减规律。再次,给出水权配置的帕累托最优定义,提出帕累托最优时水权配置状态的定理,并论证水权的帕累托配置是稳定的水权配置状态。根据极限理论,给出水权配置序列收敛于帕累托最优配置的定义,论证了在现实水权信息不对称的情况下,只有通过水权交易重新配置水权才能逼近水权配置的最优状态———帕累托配置,而依靠行政配置无法实现。最后,采用本文理论分析我国水权交易现状,指出由于我国目前水权交易成本过高,水权配置向帕累托逼近的速度慢,水权配置无法达到帕累托最优。随着我国水权交易制度的日趋完善,水权配置将达到帕累托最优,从而实现水资源的充分利用。
