Chinese housing: Built to last but likely to diminish

Residential construction is currently 23% of Chinese GDP.  (In the US it is 3.1%) The Chinese build houses and apartments of cement, and China produced more cement in 2011 and 2012 than the US did in the entire 20th century, according to China’s statistical agency.  But the economy is slowing. Electricity consumption was up only 4.4% in April. Curious though it is, the government has taken no stimulus measures.  One suspects the authorities want a slowdown.
