摘要
This paper presents a holistic method by integrating three concepts (land resources management, assets supervision and political governance for sustainability) for investigation of land administration in China, taking into consideration of cultivated land protection for a testimony with econometric method. Theoretically, in this self-organizing integrated method, land resources management focuses on the productivity of land; land assets supervision centralizes on the realization of land usufruct rights in land transference; land political governance for sustainability concentrates on harmonious linkage of economic efficiency, social stability and environmental safety of land use. Their interrelations are complex. Methodologically, the results indicate that the theoretical model is feasible to explain variations of cultivated land protection with these three concepts. Cultivated land decreases with increasing land value increment multiples, and is positive with political governance concept, but not in a linear fashion. Finally the results suggest that roles of government in land administration need to be changed and strengthened, supporting complete compensation for land expropriation and modification to policies of cultivated land.
