The Land Act of Macau 1980 divided the land into public property land of the region, private property land of the region and private land. Macao Special Administrative Region set a new land law follows this classification in 2013. There is crack between the classification and Macao Special Administrative Region Basic Law and the provisions of the City Planning Act 2013. Therefore, it’s worth exploring that whether the above division is surviving rationality, or legitimacy. What we should face up to is that the positioning and function of the City Planning Law depend on the classification of the legal status of the land. For the purposes of the current legal system in Macau, the land law is a direct tool for city planning law, and the real core of the city planning law is to how to plan the land’s use. When the government amends the law in the future, it should repeal the division of public property land of the region, private property land of the region and private land, and divide the land into state-owned land and private land.
