PC shipments to China tallied 69 million units in 2012 while 66 million were shipped to the US, where booming popularity of tablets and smartphones has eaten into sales of laptop or desktop computers, IHS reported.
"China rose to the top of the PC market for the first time ever on an annual basis last year, relegating the United States to second place," IHS said in a PC Dynamics Market Brief.
"The relatively large percentage of desktop PC shipments in China is due to huge demand in the country's rural areas, which account for a major segment of the country's 1.34 billion citizens," said IHS analyst Peter Lin.
"These consumers tend to prefer the desktop form factor."
IHS predicted the balance to shift in the coming year as competitively-priced laptops gain in popularity and the China market would begin to mirror the global 36 per cent to 64 per cent 'desktop-to-notebook' ratio.
