Abstract: Since the reform and opening-up in 1978, The basic experience gained in the field of land system reform in China is to rebuild land property rights on the basis of adhering to socialist public ownership, but not to make money by land or to collect land at low prices and sell it at high prices by goverment. By using above basic experience of reform, China’s economic and social development has made considerable progress, but these progress is mainly concentrated in the state-owned land in urban areas. When the basic experience of rebuilding land property rights continues to expand in the vast rural areas, it encounters tremendous resistance and obstacles of theory and ideal. The key to break down these obstacles lies in distinguishing collective land ownership from social insurance system, and in accordance with the basic experience to promoting the comprehensive deepening reform of collective land ownership.
