Using the location entropy, coupled coordination model, trend surface analysis and gravity model to calculate the coupling coordination degree of city function and regional innovation and analyze the situation of spatial linkages in the Yangtze River Economic Belt. The conclusions are arrived as follows: 1) in 2004-2014, the coupling coordination degree had a certain degree of improvement of the whole city unit, gradually form three continuous gathering area. The overall coupling coordination degree shows the spatial trend of "lower middle and upper middle reaches" in the Yangtze River Economic Belt; 2) Connection structure of the maximum gravitational line of the spatial linkages is relatively stable, the Yangtze River Delta agglomeration is an important and gathering area for the coordinated development; 3) The complex degree of network density and structure of the spatial linkages in the lower reaches is much higher than that in the middle and upper reaches of the Yangtze River, and gradually form a network structure of the Yangtze River Delta as the core city circle, driving the development of multi polarization in the middle and lower reaches of the Yangtze River.

Key words: urban function, regional innovation, coupling and coordination, spatial relation, the Yangtze River Economic Belt
