With the help of debts, sub-national government improved the urban appearance and make things more convenient of living for the people. However, the debt scale expanded fast in the past years, in contrast with the limited financial income, which has caused sincere worry of national government and the whole society for the debt risk.In the process of financing for the public infrastructure construction, the sub-national investment companies brought out various problems. The sub-national investment companies raise money in different ways, undertaken great risk in complex guarantee relationships of each other, which result in great pressure of debt redemption for the sub-national government.
