Nation ready to overtake US years earlier than international economists expected

Far sooner than expected and predicted, it appears that China is on the verge of overtaking the United States as the world's largest economy. Organizations such as the International Monetary Fund and the World Bank have long forecast the inevitability of China's ascent to the top of the global economic ladder, but not until 2020 or even 2024.

However, an announcement recently by the World Bank's International Comparison Program in Washington asserts that China's ascent may take place as early as this year, according to analyses based largely on purchasing power parity.

China's economy will not see hard landing

While the ICP's methodology has attracted as much criticism as attention, it does paint an important part at least of the picture of the shifting balance of economic power from West to East. The ICP's recent announcement highlights the growing power of the Chinese economy and the speed of its spectacular rise.

According to the ICP's PPP-based calculations, China's economy accounted for only 43 percent of the US economy in 2005, rising to 87 percent in 2011.

There are two limitations in the ICP's PPP approach. The first is the fact that money tends to "go further" in poorer, less-developed countries where prices are generally lower. The second is the apparent omission of any key economic indicators on a per capita basis. According to the Organization for Economic Co-operation and Development, the average income in China was 75 percent of the global average while that in the US was 370 percent.

Still, the ICP's figures highlight China's rapidly rising global economic power and should also stimulate discussion and debate on the speed of China's economic transformation and the path this may take over the coming years.

Before attempting to plot the trajectory of China's economic future, it is imperative to learn from the nation's economic emergence since the birth of the "Open Door" policy in the late 1970s. Looking back, it is clear that a nonlinear relationship appears to exist between economic emergence and time in the case of China.
