Regional economic disparity in Beijing based on Theil index

On the basis of Theil indexes,we analyzed the regional economic disparity(RED) inside Beijing during the period from 2001 to 2009.The results show that: 1) RED in Beijing has increased during the period;2) RED in the inner city comes from the disparity among the northern four districts and between north and south urban regions;3) the disparity among inner city,suburb,and exurb has the largest contribution to the general disparity;and 4) the main reasons for the RED are different nature conditions,different allocations of resource by the government,and competitive industries in some counties.
