Historically, the regional policies have been changed greatly in Mainland China ever since 1949. Since the ¡§Egalitarianism¡¨ in Mao, the ¡§ladder-step doctrine¡¨ in Deng, and the ¡§Western Investment Policy ¡§ in Jiang, each one possessed its own unique regional developing models. However, it is worth to note that the change of the models had deeply influenced the policies to determine the developing priority between coastal and inner regions. This article will focus on three questions. First, how the three different regional developing models had influenced the policies? And how the regional development had been influenced by those policies? Second, how the market system has an impact on the regional development in Mainland China? Finally, what kind of relationship existed between statecraft and market? And how did they interact each other?
