Research On The Mechanism Of Land Use Conversion

Along with social and economic development, land use conversion is ineluctable, it is the result of land use competition. In China, land area per person is much less than the average level of the world, and ecosystem condition is deteriorating. How to coordinate the relationship among ecosystem, feeding and construction is a hard task for the government. This dissertation systematically analyzes the mechanism of land use conversion, and focuses on the problem of interests adjustment.In the first chapter, the concepts of land use conversion and the mechanism of land use conversion are given. Land use conversion is that agricultural land is changed to construction uses, such as residential, industrial, commercial uses, etc.. The mechanism of land use conversion means all powers that promote or restrict land use conversion. Population increasing, urbanization, economic development and infrastructure construction will promote land use conversion, while total land area, national ecosystem security and food security, stability of territorial economic development will restrict land use conversion.The second chapter introduces the main research results of domestic and overseas researchers, and simply analyzes these results.The third chapter introduces the experiences of land use conversion control of U.S.A., Canada, Britain, Netherlands, Israel, Japan and Taiwan province of China, and analyzes what inspiration can Mainland China get from their experiences.In the forth chapter, a theory model of land use conversion is given, which is used to analyze the influence of market mechanism and government intervene. Agricultural land has high externality, so market will be failing to allocate land resources between the two uses. Therefore, the government must control the process of land use conversion. There are two methods which the government can use, one is to decrease the marginal revenue of construction land, the other is to increase the agricultural land's marginal revenue. This chapter also analyzes the current approaches of land use conversion and their procedures and characters in Mainland China, and analyzes the types structure and territorial distribution of land use conversion.The fifth chapter investigates the interests mechanism of land use conversion. The land price increment model during the process of land use conversion is established, and the method to calculate the revenue of land use conversion is designed. When agricultural land is converted to nonagricultural uses, the two land markets are different, the clear price in the construction land market is higher than that in the agricultural land market, so there is land price increment revenue during the process of land use conversion. According to the designed calculation method, this chapter also empirically examines the land use conversion revenue and its distribution in Shaoxing downtown, Shaoxing Economic Development Zone and Hangzhou Economic and Technological Development Zone. The empirical research result indicates that in cities like Shaoxing downtown, there will be ?02 million net revenue when 1 sq. km. agricultural land is converted. The revenue is distributed among the local government, the central government, the village collective and farmers, the percentages respectively are 63.8%, 20.56% and 15.66%. Because the local government and farmers can gain net revenue in the process of land use conversion, so they havemotivation to promote land use conversion. The central government will assume the ecosystem and food expense of land use conversion, so it inclines to control land use conversion. To successfully control land use conversion, the central government should reduce the local government's net revenue from land use conversion, and increase the farmers' agricultural land operation revenue.The sixth chapter examines the participators' behavior in the process of land use conversion. The main participators include the central government, the local government, village leaders and farmers. The village leaders' and farmers' be...
