This paper, based on GDP per capita from 2000-2010, uses standard deviation, variation coefficient to describe the temporal features and uses deviation, ratio and relative development speed to describe the spatial features of the economy of Xinjiangs 14 regions. The reasons for regional economic disparity in Xinjiang are analyzed, and the approaches to promoting regional economic development are presented. The economy in Karamay is more developed than other regions. The development level is middle in Urumqi, Changji, Turpan and Bayinggol, but low in other regions, which is connected with natural environment, location, transportation, policy, industrial structure and population. This paper suggests enhancing governmental controls, optimizing regional industrial structure, controlling population, enhancing population quality and boosting Xinjiangs coordinated development.
