摘　　要：将水资源作为生产要素,通过基于面向输出的C2GS2模型DEA相对有效性评价,建立有效生产前沿,分析产出的技术效率和生产要素的使用效率。利用具有积性误差的Hicks中性技术进步Cobb—Douglas生产函数,通过有效生产前沿时间序列数据COLS回归,建立动态随机前沿生产函数。利用序列数据建立序列与截面水资源边际效益模型、缺水损失模型及序列节水边际成本模型。Regarding water resources as one of the elements of production, the efficient production frontier is built based on the DEA relative efficiency evaluation with C^2GS^2 model of output oriented. Technical efficiency of production and utilization efficiency of the elements of production are analyzed. By using the Cobb- Douglas production function with Hicks neutral technical progress and multiplication random error, the dynamic stochastic frontier production function is constructed through regression analysis of series data for efficient production frontier. The serial and the sectional modals of marginal benefit for water resources utilization , the serial and the sectional modals of water shortage economic loss and the serial modal of marginal cost for water saving are structured based on the serial data of production efficient frontier.
