The structure of farmland property rights is an important bridge for constructing an effective link between the distribution of land value-added income and the constitutional order. From the perspective of the structure change of farmland property right, the nationalization mechanism of the traditional land value-added income in China is in fact largely in line with the socialist land rent state-owned principle and the land benefit sharing order established in the Constitution of 1982. However, since the land clause of the constitution has been injected with the ideological gene of land interest distribution, "the other half of the constitutional order" in which farmers as a whole share the land value-added income has been ignored for a long time. Under the background of new urbanization, China has carried out the rural land management system reform of "the same land and the same rights" and "empowering the farmers". Its essence is the continuation of the constitutional order rather than the replacement. The main mechanism of land value-added income distribution in China is still the land acquisition compensation system. In order to realize the fair sharing of land value-added income in China, we must return to the complete land benefit sharing order of socialist "state-collective" monism, and follow the requirements of substantive equality, by limiting the regional comprehensive land price with the goal of "urbanization of people", adopting a "land finance" policy in favor of rural and agricultural development, and breaking the dual system of urban and rural household registration to realize the integrated development of urban and rural areas, so as to promote farmers to participate in the whole process and share land interests.
