BEIJING, Dec. 23 (Xinhua) -- China's fiscal funds for education in 2016 stood at 3.1 trillion yuan (480 billion U.S. dollars), with an average annual increase of 7.9 percent from 2012.

The ratio of the funds to GDP exceeded 4 percent each year during the period, according to a report released on Saturday.

"Overall funds for education in 2016 reached 3.9 trillion yuan, over 80 percent of which were provided by the government," said the report delivered to the Standing Committee of the National People's Congress (NPC) at its six-day bimonthly session.

Over half of the fiscal funds for education were used for nine-year compulsory education in 2016. Expenses on teachers' salaries and students' financial aid also accounted for over half of the fiscal funds for education in 2016, 10.6 percentage points up from 2012, said the report.

Fiscal funds for education transfer payment inclined toward relatively backward areas in 2016, with 84 percent going to central and western regions, which have fallen behind the east.

Compared to 2012, education funds for every junior middle school student, elementary school student and kindergarten kid in rural areas increased in 2016 by over 50 percent on average, said the report.

In 2016, the gross enrollment rates for the pre-school education reached 77.4 percent, 87.5 percent for senior middle schools, and 42.7 percent for higher education. The net enrollment rate for elementary schools was 99.9 percent, said the report.

Over 80 percent of children of migrant workers have received compulsory education in cities where their parents work.

Since 2012, 698.1 billion yuan of financial aid has been granted to students from impoverished families, said the report.
