This paper analyses the local governments’ public policies in a three-section economy. The economy consists of central government, local governments, and private enterprises. The influence of fiscal decentralization on the behavior pattern of local government is examined. Followed by the consideration of soft budget, the mobility of capital is introduced in the model. The model describes the behavior of China’s local government, consequently providing an explanation to the local government’s capital attraction and financing incentives. This paper intends to solve the local government’s debt problem, while providing a clue to reform tax regime and improve the evaluation system of government performance.
