Article 8 of the Measures for the Administration of Central Financial Discounted Funds for Capital Construction Loans stipulates that the financial discount rate for capital construction projects shall not exceed the current bank loan interest rate. The financial discount subsidy rate is determined by the Ministry of Finance according to the annual discount interest fund budget control index, the bank loan interest rate in the current year of the project and the demand for discount interest funds in the current year of the project (except for specific projects specified by the State Council), and in principle it is not higher than 3%. At the same time, in order to encourage independent innovation, the national high-tech industrial development zones are ranked according to the indicators of independent innovation ability of each development zone, thus widening the gap. Divided into two grades of subsidies, the subsidy rate gap is about 30%.
