Feb 7 (Reuters) - China shares rose on Friday, as strong gains in high-tech firms helped offset losses in Chinese financial and property stocks after a survey showed further signs the world's second-largest economy was losing momentum.
The CSI300 index of the leading Shanghai and Shenzhen A-share listings closed up 0.5 percent, while the Shanghai Composite Index rose 0.6 percent to 2,044.5 points as traders returned from a week long Lunar New Year holiday break.
The ChiNext Composite Index, China's Nasdaq-like board for high-growth, mainly high-tech start-up firms, soared 2.5 percent to a record high.
The HSBC/Markit Services Purchasing Managers' Index (PMI) retreated to 50.7 in January, its slowest pace in almost 2-1/2 years after firms secured a smaller volume of new business, a private survey showed, adding to growing signs of slackening in the Chinese economy.
China data for January money supply and loan growth are due by Feb. 15.
