Despite the great achievement of eliminating poverty, the gap of income between different social classes is still enlarging, and infrastructure construction is deemed as valuable policy for controlling income inequality. This paper firstly testifies if water infrastructures exert significant influence on regional income, and then analyzes the co-mechanism among population, transportation and water infrastructures, and finally verifies heterogeneity of the influence. Empirical results show that: water infrastructure exerts significantly greater impact than population and transportation infrastructure on regional income; population factors and transportation effect on mode of the influence; regional difference exists, that’s eastern and central China show absolutely adverse effect of the influence with western and northern China. Therefore, investment on infrastructure construction needs to decline on, such as sewage, and construction plan should take consideration of, for instance, population of area, blocks, and water reservation, and etc.
