Moving further upstream, weakened steel demand would translate into lower demand for iron ore. With weaker-than-expected demand, the iron ore inventory reached a record level in June, with 113 million metric tons sitting at ports. Prices will continue to be depressed, and that means private mines in the country burdened by high costs will need to close. Similar negative pressure is expected in the coal sector, even if to a lesser extent because its downstream customers, for example, power plants, are a bit more diverse.

More importantly, the importance of the property sector to government revenue is also increasing. Income from land use right transfers contributed about 28.2 percent of total government revenue last year, compared with 16.8 percent in 2009. Unless the government speeds up the transformation of its revenue structure, which is less likely in the near-term, income from the property market will remain an important component in the government revenue mix.

The importance of the property sector to the Chinese economy is significant, and a collapse of the sector needs to be avoided.

In the medium-term, property demand should be led by the government's urbanization plan. The urbanization rate reached 53.7 percent last year, surpassing the 51.5 percent target of the 12th Five-Year Plan (2011-15), but it is still far behind developed economies such as Australia (89.2 percent) and the US (82.4 percent), or even emerging economies such as Brazil (84.6 percent) and Russia (73.8 percent)

Continued urbanization will also improve the standard of living for people who now live in rural areas, because the average income for urban dwellers tends to be higher. In fact, the difference in income between rural and urban households more than doubled between 2006 and last year, from 7,458 yuan a person to 15,972 yuan a person. The government aims to reduce income inequality and improve the standard of living of its people, and urbanization may be a means to that end.

The medium-term outlook for China remains bright, but, as John Maynard Keynes famously said, "in the long run we are all dead", and short-term challenges should not be neglected. While a moderation of growth is expected as reform takes place, a free fall would do tremendous harm.
