Your question is not clear enough and it is difficult to give you a specific answer.

The conversion of infrastructure appropriations within the national budget into loan investments is referred to as "appropriations to loan investments." This refers to capital construction investment that was originally allocated from the national budget and replaced by loan arrangements from the Construction Bank. Its essence is to implement credit management of fiscal appropriations within the national budget and change the free use of capital construction investment into paid use. The interest earned before the "appropriation-to-loan" project is completed and put into production is not included in the design budget of the construction project and is not included in the investment scale. However, upon completion, the interest on the loan during the construction period should be included in the value of the fixed assets. Our country implements differential interest rates for different construction projects using this type of investment, and stipulates different repayment periods: for example, the annual interest rates are 2.4%, 3%, 3.6%, 4.2%, etc. according to different industries. For the construction and long-term product projects For projects involving high-energy-consuming products in energy-stressed areas, the annual interest rate is 12%.
