This practice began in 1985. Prior to this, the two sessions were held in the middle and late years of the year, and there was no charter.
1982 during the revision of the constitution, many people thought that the date of the National People's Congress should be fixed and institutionalized so as to examine and approve the budget and national economic plan in time.
The Second Session of the Seventh National People's Congress (1989) adopted the Rules of Procedure of the National People's Congress, and decided that the National People's Congress should be held in the first quarter of each year, but in March, which has realistic basis.
It is an important duty of NPC to approve work reports and budget reports.
In practice, the budget expenditure in the first quarter of each year is relatively large, accounting for one-third of the annual expenditure. Therefore, it is not too late for the National People's Congress to approve the budget.
The fiscal year is based on the natural year. If the NPC meets too early, the relevant data can't be counted, and it is not accurate to make a budget according to the situation of the previous year. The meeting will be held in March, which can reasonably take into account the needs of both.
Convening the National People's Congress and the National People's Congress in a fixed month is conducive to the highest organ of state power exercising its functions and powers in accordance with the Constitution and making early arrangements for the important work of the country in that year. It is also conducive to the central and state organs, provincial organs and other relevant parties to make overall arrangements for the work throughout the year.
