The construction period of new projects is 4 years, with balanced loans in different years. The loan in the first year is 6,543,800,000 yuan, and the loans in subsequent years are 5,000,000 yuan, with an annual interest rate of 6. Investment in fixed assets is divided into construction period and production period, which are distributed in the construction period in different years. For large-scale fixed assets projects, due to the long construction time, the funds are used according to the construction cycle and gradually put in place according to the needs of use, which improves the efficiency of capital use on the one hand and reduces the cost of capital on the other. A year's loan is not in place at one time, but in stages from the beginning of the year to the end of the year, so it should be divided by 2.
