Water shortage has become a bottleneck to restrict the sustainable development of China's economy, especially in the Liaoning Coastal Economic Belt (LCEB). So the research on marginal effect of water resources is important and necessary for the sustainable development of LCEB. The theory of marginal effect is the cornerstone of this paper. To quantitatively analyze the impact of water resources on the regional output value based the three industries, the paper took water resource as the factors of production. And, in this study, the Cobb-Douglas function was employed in the computation of marginal revenues of water in LCEB over the period of 2002-2011. The results indicated that, in 2002-2011, the marginal effect of three industries increased year after year, and the marginal effects of agriculture, industry and the tertiary industry water was 4.11, 82.30 and 154.93 yuan/m3 respectively. The marginal effect of agriculture water was significantly less than that of industry and the tertiary industry water. Due to the different nature of the three industries, their influence factors are abundant and varied. To investigate the key factors of marginal effect for water resources, multiple linear regression model was built based on the results. Our model showed that the influence factors exactly revealed the impact of marginal effect of water resources, and the factors had both positive and negative effects. The results showed that: the factors that affected agricultural water were the water consumption of agricultural output value per ten thousand yuan, the influence of government, the yield per unit area, and the amount of fertilizer consumption; the factors affected marginal effect of industry were the water consumption of industrial output value per ten thousand yuan, the amount of industrial wastewater emission, the influence of government, and the degree of market demand; the factors affect marginal effect of the tertiary industrial water were the water consumption of the tertiary industry output value per ten thousand yuan, the level of urbanization, the influence of government, and park green area per capita.
