An old Chinese myth

There is An old Chinese myth that 40% of the GDP of the PRC is driven by exports. However, the real figure is probably closer to 10%

MOST people suppose that China's economic success depends on exporting cheap goods to the rich world. If so, its growth would be seriously dented by a stuttering American economy. Headline figures show that China's exports surged from 20% of GDP in 2001 to almost 40% in 2007, which seems to suggest not only that exports are the main driver of growth, but also that China's economy would be hit much harder by an American downturn than it was during the previous recession in 2001. If exports are measured correctly, however, they account for a surprisingly modest share of China's economic growth.

The conclusion of the article is:

An American downturn will cause China's economy to slow. But the likely impact is hugely exaggerated by the headline figures of exports as a share of GDP. Dragonomics forecasts that in 2008 the contribution of net exports to China's growth will shrink by half. If the impact on investment is also included, GDP growth will slow to about 10% from 11.5% in 2007. This is hardly catastrophic. Indeed, given Beijing's worries about the economy overheating, it would be welcome.

The American government frequently accuses China of relying excessively on exports. But David Carbon, an economist at DBS, a Singaporean bank, suggests that America is starting to look like the pot that called the kettle black. In the year to September, net exports accounted for more than 30% of America's total GDP growth in 2007. Another popular belief looks ripe for reappraisal: it seems that domestic demand is a bigger driver of China's growth than it is of America's.

Emphasis Mine

This is relatively good news for Australia in the light of the impending economic slow-down in the US.
