The rise of urbanization
The growth of megacities will drive massive infrastructure spending. The UN predicts that 69% of the global population will live in urban areas by 2050, up from 50% in 2010. In 2007 half of global GDP came from 380 cities in the developed world, according to McKinsey. By 2025, 136 new cities should enter the top GDP ranks. All those cities will be in the developing world, and a full 100 of them will be in China. This trend will help major infrastructure players like China Construction Bank (No. 77) and China State Construction Engineering (No. 100).
