the inter-annual budget balance mechanism is an improvement on the current single-year budget balance mechanism, which means establishing and improving the inter-annual and reasonable balance mechanism, implementing taxation according to law, hardening expenditure budget constraints, and giving better play to the role of fiscal macro-control.

Its main contents are as follows: First, cross-year balance should be considered in budget preparation. The fiscal revenue and expenditure budget can be deficit due to policy needs, but it should be made up by years after the policy is introduced. The second is to standardize the use of over-income and make up for short-income. In case of over-receipt in budget implementation, in principle, no expenditure will be arranged in the year of over-receipt, which will be used to reduce the fiscal deficit, dissolve government debts, or supplement the budget stabilization fund, and be included in the overall arrangement of future annual budgets; If there is a short income, it will be solved by transferring the budget stabilization fund, cutting expenditure or expanding the deficit according to the procedure. The third is to weaken the assessment of income budget, and the income budget will shift from binding to anticipation, and promote tax collection and management according to law. Fourth, strengthen the review of expenditure policy and expenditure budget, and harden the expenditure budget constraints.
