Hong Kong's gross domestic product (GDP) went up 6.8 percent in real terms in 2010 year-on- year, the city's Census & Statistics Department announced Monday.

According to the department, Hong Kong's GDP grew 6.2 percent in the fourth quarter of 2010, compared with the 6.7 percent year- on-year rise in the third quarter.

During the same three-month period, net output in all the service activities taken together was up 6.2 percent in real terms and for 2010 as a whole an increase of 6.8 percent was recorded.

Net output in the import and export, wholesale and retail trades sector grew 9.4 percent in real terms in the fourth quarter, moderating from the 15.9 percent increase in the third quarter.

For 2010 as a whole, net output in this sector was up 15.5 percent in real terms, in contrast to the 9.4 percent decrease in 2009. The sharp rebound last year was in tandem with the marked revival in trade flows and strong consumption demand.
