Abstract: The differences on the reform of land system mainly focus on how to promote the entry of collective construction land into the market. From the perspective of farmers' land rights, the main stream view hopes to fundamentally change the land acquisition system by borrowing from the market, which is not in line with the constitutional order of China's land system, nor conducive to the Orderly Urbanization of China's land. Based on the long-term practice of land system reform in Southern Jiangsu, Chengdu and the Pearl River Delta, three different types of market entry modes are extracted and different logics for local governments are analyzed, which constitute the background of deepening land system reform. Combined with the interpretation of the land management law (Amendment), it is believed that the goal and nature of the legislation of the state for the land market should be accurately understood, and it should be clear that land acquisition and market entry constitute the urban and rural construction land market with unified internal rules, so as to avoid falling into the pattern of binary opposition.
