BEIJING — China's fixed-asset investment went up 5.8 percent year-on-year in the first eight months of this year, data from the National Bureau of Statistics showed on Sept 16.

Fixed-asset investment from January to August totaled 36.71 trillion yuan (about $5.3 trillion), the bureau said in a statement.

The growth quickened from a 5.7 percent increase posted in the first seven months.

From January to August, fixed-asset investment from the private sector increased 2.3 percent from a year earlier to 20.31 trillion yuan.

Investment in infrastructure and manufacturing gained 8.3 percent and 10 percent year-on-year during the period, respectively.

Investment in property development went down 7.4 percent year-on-year in the first eight months.

Investment into the high-tech industries saw stellar growth in the same period, with that in the high-tech manufacturing and services sectors jumping by 23 percent and 14.2 percent year-on-year, respectively, the bureau's data showed.

China has made a series of pro-investment moves this year. For instance, local governments nationwide have expedited the use of special-purpose bonds to catalyze investment.

The latest data shows that 3.52 trillion yuan worth of special-purpose bonds in total had been allocated as of the end of August, with those issued for project construction almost hitting the annual quota.
