Abstract: Adjusting spatial structure is an important way to optimize factor allocation and reduce regional disparities. Using the models of gravity and gravity division, this paper analyzes the evolution of regional economies gravities during 19902012, and finds that 2003/2004 is the turning point of this process. The gravities of regional economies are shifting to the central and western regions since 2003/2004. The effects of government intervention on the shift of gravity are reducing since 2003, while human capital becomes a new force driving the shift of gravity. The evolution of gravities looks like a flyinggeese pattern which is composed of investment, GDP, trade and consumption.
