A Study on the Equilibrium of Chinese Urban Infrastructure Construction Investment Based on the Gini Coefficient

The equilibrium of urban infrastructure construction investment is significant for the equilibrium of regional economy development and social stability. This paper quantitatively analyzes the equilibrium of urban infrastructure construction Investment by the method of Gini coefficient. First of all, this paper selects Chinese urban infrastructure construction investment index through the literature research. Then, this paper draws the Lorenz curve and calculates the population and GDP Gini coefficient of Chinese urban infrastructure construction investment. The results show that, on the whole, Chinese urban infrastructure construction investment is in a state of "comparative equilibrium" at present. From 2004 to 2013, Chinese urban infrastructure construction investment based on population develops toward a more balanced direction. The equilibrium of urban infrastructure construction investment based on GDP nearly remains unchanged. China gives more and more attention to the equilibrium of Chinese urban infrastructure construction investment based on population.
