China's top economic planner on Nov 7 published 21 policy guidelines to localities and departments around the country in a bid to vigorously support the development of private investment.

Boosting private investment is conducive to creating jobs and promoting high-quality economic development, as it accounts for more than half of the total social investment, the National Development and Reform Commission (NDRC) said in a notice.

China will support private investment in participating in the construction of 102 major projects. Among them, transportation construction and water conservancy should be accelerated, it said.

According to the notice, private investment should be treated equally in bidding, and private capital will be encouraged to actively participate in the construction of innovation platforms such as industrial and technological innovation centers at the national level.

To facilitate the development of the platform economy, the State will give more emphasis on investment in key projects such as artificial intelligence, cloud computing, and blockchain.

The notice also touched on specific policy support in tackling high financing costs among private investment projects such as improving information-sharing mechanisms; and guiding financial institutions to lend support and innovating financing channels.

The Chinese economy expanded 3.9 percent year-on-year in the third quarter, faster than expected.

The country's economy has generally maintained a recovery momentum in spite of downward pressure, and the potential economic growth rate this year will remain within a reasonable range, the central bank governor Yi Gang said last week.
