【 摘 要 】

From the perspective of western economics, this paper discusses the evaluation model of water resources value. It is concluded that the evaluation of water resources value can't solely rely on the labor value theory or western utility value theory in economics. Based on the previous evaluation of water resources value, with the combination of two theories, a four-quadrant model of water resources evaluation is established. The model shows that utility value is the starting point of water resources value research. As the demand of water resources increases, more and more labor input and labor value gradually become prominent. Throughout the whole process of interaction, the economic development and technology improvement is an important factor for the evaluation of water resources value, the two factors need to be fully considered in the process establishing the model.
