BEIJING (AFP) - China on Saturday published the draft of its 13th Five-Year Plan, a blueprint for economic and social development over the 2016 to 2020 period.

Such plans are a legacy of China's command economy era, but still guide policymakers, and the 148-page document is due to be approved by the ongoing National People's Congress, the country's Communist-controlled Parliament.

Here are some main targets listed in the draft plan.

1. To grow China's economy, the world's second-largest, by an average of at least 6.5 per cent a year over the period. Gross domestic product (GDP) to go from 67.7 trillion yuan (S$14.3 trillion) last year to more than 92.7 trillion yuan in 2020.

2. The service sector to account for 56 per cent of GDP by 2020, up from 50.5 per cent in 2015.

3. To cap total energy consumption under five billion tonnes equivalent of coal by 2020, compared with 4.3 billion tonnes' equivalent of coal last year.

4. To cut energy consumption and carbon dioxide emissions per unit of GDP by 15 per cent and 18 per cent respectively from 2015 levels by 2020.

5. City air quality to be rated "good" or better at least 80 per cent of the time by 2020, up from 76.7 per cent in 2015.

6. To raise installed nuclear power capacity to 58GW by 2020, when another 30GW are scheduled to be under construction. Currently, 28.3GW are installed, with 26.7GW under construction.

7. To expand the high-speed railway network to 30,000km by 2020, from 19,000km last year, and build at least 50 new civilian airports.

8. To boost per capita disposable income by 6.5 per cent or higher every year. The figure grew by 7.4 per cent in 2015.

9. To create a total of 50 million jobs in urban areas over the five years.

10. Permanent urban residents to make up 60 per cent of China's total population by 2020, up from 56.1 per cent last year. The proportion of people with urban "hukou", or household registration, is to reach 45 per cent of the total population.
