Investment in education has increased in recent years; the proportion of the overall budget allocated to education has been increased by one percentage point every year since 1998. According to a Ministry of Education program, the government will set up an educational finance system in line with the public finance system, strengthen the responsibility of governments at all levels in educational investment, and ensure that their financial allocation for educational expenditure grows faster than their regular revenue. The program also laid out the government's aim that educational investment should account for four percent of GDP in a relatively short period of time.
