One of the most remarkable changes in Chinese cities in the last decade was a change in social "equality", with the rise of new poverty both in individual communities and some social groups in urban society. However, there is little social assistance and public infrastructure for the migrants. Governments or communities or individual should pay attention to the control of new urban poverty and new slums. This paper consider that it is necessary to launch a successful policy, which include mainly: 1) accommodating urban growth through low cost investment projects; 2) urban economy depends heavily on successful macroeconomic policy; 3) to broaden the three channels linking adjustment to the incidence of urban poverty; 4) to restructure urban economic based on the high or new technology; 5) to coordinate relationship between urban economic growth and environment management for sustainable development of Beijing′s metropolitan fringe.展开更多
