| The institution of land development rights has formed perfect system and practical foundations in Britain, the United States, France and other countries. The contradictions and conflicts about it have emerged for a long time even though no official statements have attached to it in China. The research on the theory of land development right by Chinese scholars is also wide, but is to be further. Along with the rapid economic development and the increasing occupation of cultivated land for constructions, the top priorities for us are to have the problems of increasingly cultivated land resources occupation and ecological environment pollution solved. Foremost, thanks to entailing problems of the distributions of added value with changing the use of cultivated land, the farmers’legal interests are not secured and maintained and a multitude of farmers’living rights are threatened, which harms the stability of the society and the country. Therefore, this paper puts forward the concept of cultivated land development rights, and on the basis of referring to the research literatures about land development right at home and abroad, under the direction of the theory such as the legal basis, the economics of property rights, land evaluation and land value increment, The research and exploration conducted in this thesis are based on the LDR theory and its price appraisal theory and appraisal methods with such methods as comparison, document reference, quantitative and qualitative analysis. The core content in the paper is the research on the evaluation to the price of cultivated land development right. The author adopts the method of the fuzzy comprehensive evaluation and the three scale analytic hierarchy process in improvement to estimate the price of cultivated land, and then gets the price of the land for construction from2001to2010from the statistical data such as the land transfer revenue and the total area of transferring land. The land development fee is determined by the land development fee in the country and the local land development fee. Profit is calculated by profit rate on costs. The interest is calculated through loan ratio in years. And on this basis, the author using differential value method to estimate the price of cultivated land development right. In this paper, Hunan province is taken as the research object for empirical research, and according to differential value method, the author estimates the price of cultivated land development right, and analyzes their changing trend and dynamics in Hunan from2001to2010. The writer demonstrates the ration and correction of the price estimated method of cultivated land development right with objective, accurate and realistic results. It blends theory and practice.In a word, the research on the estimation for the price of cultivated land development right has firmly laid theoretical foundation for effective protection of ecological environment, optimizing transmission of cultivated land resources, refining the distribution mechanism of added value from transferring the using of land, building up the compensation program of the scientific and comprehensive cultivated land requisition as long as the consolidating the implementation of land utilization and rural and urban formulation. |
