摘　　要：引入效用函数,采用"期望效用最大"的优化原则,获得效率最优的决策单元,并进一步定义了基于效用函数的收益型Malmquist指数,同时对其影响因素进行了分解和经济解释,从而丰富了Malmquist指数模型体系,最后用线性规划给出了求解方法.The former research of Malmquist index all localized in certain situation, namely, the direction of decision making unit approaching production frontier is radical or given in advance. But because of the affects of many uncertain factors, the direction of decision making unit approaching production frontier can＇t be given in advance. But those traditional metheds can＇t work out under this situation, so, based on the principle of ＂Make expecting utility maximal＂, the optimum decision-making program of the relatively efficiency estimation of Decision Making Units is obtained. Then, defines revenue Malmquist index based on utility function, so, combined with it Malmquist index methodology becomes more perfect. Then, factors of revenue Malmquist index on utility function were decomposed. Finally method of Computation is given.
