Bloomberg news reports on the impact to China’s Gross Domestic Product (GDP) from China’s manufacturers’ damage to the environment. Their conclusion, the damage is so great that they will have to spend up to 2% of their GDP on cleaning up the mess just to keep it from getting worse. They’ll have to spend 4% to try to get ahead of the damage they’ve already done.
China, the world’s worst polluter, needs to spend at least 2 percent of gross domestic product a year — 680 billion yuan at 2009 figures — to clean up 30 years of industrial waste, said He Ping, chairman of the Washington-based International Fund for China’s Environment. Mun Sing Ho, a senior economist at Dale W. Jorgenson Associates and a visiting scholar at Harvard University in Cambridge, Massachusetts, put the range at 2 percent to 4 percent of GDP.
Failure to spend that much — equivalent to the annual GDP of Vietnam — may cost the Chinese economy half as much again in blighted crops, health costs and pollution-related expenses, He said: “The cleanup can’t catch up with the speed of pollution” if spending is less.
China gave the world false savings in ‘cheaper’ goods because the producers did not have to pay the full cost of the damage that was being done. It wasn’t labor price advantages that took the work to China, it was not having to comply with environmental laws in place in the developed countries.
In a recent post, economist Michael Pettis takes this analysis further on the implications for China.
This article suggests that a significant portion of Chinese growth came with a destruction of value that should have been deducted from that growth. After all, if you create net $100 of chemicals, but in so doing you pollute a nearby river to the extent that future economic production associated with the river is reduced by $100 (there will be less fishing, perhaps, or less agricultural production, or less usable water, or more health care costs), then the net value you created is 0, not $100, although of course you as the polluter might earn $100 today while the rest of the country loses $100 over the future.
When you add the impact of misallocated investment and environmental degradation, the necessary cumulative adjustment to Chinese GDP might be huge. For example, if the two adjustments combined range from 2 to 4 percentage points annually, over one decade China’s “true” GDP (whatever that means), would be below the official numbers by anywhere from 16-31%. Over twenty years official GDP would be overstated by 31-52%. That means that we are massively overstating GDP today and will experience very low apparent GDP growth for many years in the future as the official number returns to some reasonable approximation of the real number.
