“Poverty of Cities" which is a reflection of informal residing.

Therefore the poverty center was gradually transferred and focused in to the big cities.

Mean while, the globalization reinforced the employment and economic activities in big cities in nationwide scales, and left a wonderful effect.

The balanced economy depends on development stability of city dwelling and this fact will be accessed only if the cities become a source of comprehensive productivity, both economically and socially, so that all society levels draw benefit of this development.
