Abstract：This paper selects the relevant data in 1997-2013 and uses Gini coefficient and the decomposition method to calculate the spatial equilibrium degree and source of transport infrastructure in the Yangtze River economic belt. This paper constructs ER index, EGR index, and LU index to measure the spatial polarization degree of transport infrastructure in the Yangtze River economic belt. On this basis, this paper explores and empirically tests the influencing factors of spatial equilibrium and polarization of transport infrastructure in the Yangtze River economic belt. Eventually, this paper proposes the interconnection policy recommendations of transport infrastructure in the Yangtze River economic belt. The results show that:Firstly, transport infrastructure show a trend of rapid growth in the Yangtze River economic belt between 1997-2013, but there is the phenomenon of spatial gap, and the spatial non equilibrium degree of highway density and railway density is in the order of decreasing, and the inter regional gap is the main reason leading to the spatial non equilibrium of transport infrastructure. Secondly, there is the phenomenon of spatial polarization of transport infrastructure in the Yangtze River economic belt between 1997-2013. Thirdly, this paper explores the influencing factors of spatial equilibrium and spatial polarization of transport infrastructure in the Yangtze River economic belt from four aspects of fiscal expenditure, international trade, human resources and new economic geography, and cyclic accumulation effect, urbanization rate, Porter externality, transport finance expenditure, average education years, population density all pass the significance test, have an impact on transport infrastructure, the per capita GDP has a positive effect on highway density, and foreign direct investment has a negative effect on railway density.
