During the Jan-Oct period, fixed-asset investment from the private sector increased 1.6 percent from a year earlier to 25.84 trillion yuan.

Investment in infrastructure and manufacturing gained 8.7 percent and 9.7 percent year-on-year during the period, respectively. Investment in property development went down 8.8 percent year-on-year in the period.

China's high-tech industries continued to see a stellar expansion of fixed-asset investment in the first 10 months, with that in the high-tech manufacturing and services sectors jumping by 23.6 percent and 14 percent year-on-year, respectively, NBS data showed.

Specifically, investment in the sub-sectors of electronic and communication equipment manufacturing and research and design services soared 28.7 percent and 22.5 percent, respectively.

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

Over 3.54 trillion yuan worth of new special-purpose local government bonds were issued in the first three quarters of this year, data from the Ministry of Finance showed.
