Research On Potential Exploitation And Policy Of Urban Land Intensive Use

Land is the basic resources of human survival and development, it is not only the carrier of the human life and production activities,but also the indispensable production material of regional economic development. Cultivated land is the essence of land, a certain amount of cultivated land is the guarantee of food security, ecological security and social stability. Along with the sustainable development of economy and society,on the one hand, the quantity demanded of cultivated land is increasing rapidly, on the other hand, the growing population and material life need higher request for the agricultural land protection and the food security, the "dilemma" situation of land management aggravates increasingly. In order to protect the limited arable land resources, ensuring the national food safety, ecological security and social stability, we must not only adhere to carry out the strictest arable land protection system and the strictest frugal land system, but also use the urban land intensively, and fully exploit the potential of urban construction land. Therefore, adhere to the economical and intensive use of land is not only the major way to break the dilemma of "safeguard development, protect resources", but also "the topic of the implementation of the scientific development concept, the strategy measure of ensure national grain safety".The domestic researches about intensive urban land use started later, the existing researches mainly focused on the evaluation of land intensive use and related countermeasures of specific objects, such as large and medium cities, development zones. But whether the potential can be exploited influenced by many factors, based on intensive evaluation and potential measure of different land types, this research analyzes the land use behavior decision systems of the urban land managers and land users, explore the policy conditions that needed of intensive use behavioral decisions, then take this as the basis of policy setting, combine the potential exploited of different types of land with the improvement suggestions of existing policies from policy makers and experts, reference the foreign experience of intensive urban land use, synthetically put forward the policies improvement suggestions. It has important meaning for maximum exploiting urban land potential.The thesis is divided into nine chapters:the first chapter is the introduction. It introduces the background, objectives, significance, methods, technology route, and possible innovations of research, through the analysis of current research at home and abroad, overall the grasp of the research about existing urban land intensive use, then point out the inadequacies of the existing research and the need for further research. The second chapter is the basic concepts and theoretical basis. It clear the connotation of urban land intensive use and the potential of urban land intensive use, at the same time, sort out the basic theory of the comb, mainly including location theory, the law of land diminishing returns, the combined effect theory, game theory and the theory of sustainable development, all of these provide theoretical guidance.The third chapter is the overall evaluation and econometric analysis of urban land intensive use in Wuhan City, In this chapter,based on the consistent principle, the representative principle, forward-looking and guiding principles, scientific and operational principle, sustainable development principles, adjust measures to local conditions and comparability principle, combined with qualitative analysis and quantitative analysis principle, evaluation index system of urban land intensive use which is composed of four index layer16factors layer has been build, which including land investment level, land use degree, land use efficiency and land use sustainable degree, and it use the principal component analysis method to determine objective weight of each evaluation, then calculate the urban land intensity of Wuhan City from1999to2009. Urban land intensity as the dependent variable, per capita GDP as the independent variable, it use quantitative analysis methods such as Granger causality tests, cointegration test, error correction model and so on to in-depth analysis the inherent mechanism between them, which provides reference for correctly handling the relationship between economic development and urban land use.The fourth chapter is intensive evaluation and potential exploit analysis of industrial land in Wuhan City. Through building three target layer, such as land use condition, land use effective, the management performance, and6sub-target layer,15index layer, which including the degree of land development, structural condition of land, land use intensity, the input and output efficiency, land use regulatory performance and the land supply market, it compose evaluation index system and evaluate the intensive industrial land use of Wuhan City. The ideal value of the evaluation are decided by experts ask method, the target method, the development trend estimate method and the advanced experience approximation method. The evaluation results show that the excavation potential of overall industrial land in Wuhan City is great but the spatial distribution of potential types is uneven.The fifth chapter is the land use standards and intensive evaluation of industrial enterprises. Based on531copies questionnaire survey about the typical industrial enterprise in Hubei province and taking19industrial trade as study object, it use interval estimation methods to explore the land use standards. It not only provides a basis for intensive evaluation and potential measure of corporate land use, but also provides reference for the access of different industries. On this basis, it build the evaluation system of intensive land use for industrial enterprises through four sub-target layer and nine factors layers, which including land use structure, land use intensity, land investment and land productivity, and use the Bayes discriminate method to discriminate3industrial's19typical industrial enterprises of the industry intensity of Wuhan City and estimate the excavation potential.The sixth chapter is the evaluation of intensive residential land use and the analysis of its potential exploitation. This chapter uses the method of divided functional area to analyze the intensive residential land use and the available potentiality of Wuhan by selecting six indexes including complete degree of infrastructure, green ratio, population density, realized level of land price, integrate plot ratio and building density. The results show that the excessive use district is mainly distributed in the both side of Hankou libration Avenue, the intensive use district are mainly distributed in the both side of Yuemachang and Wulue road in Wuchang, and moderate use district is mainly distribute in Hanyang area. The absolute magnitude potential of residential land is3154.37hm2, which shows that the available potentiality is large.The seventh chapter is economic analysis of urban land use's behavior decision. This chapter uses the games theory, monopoly market theory and externality theory of economics to analyze the land behavior of the local government and land developers in optimizing allocation of urban land resources. The results show that local government stems from the consideration of maximum political achievement choosing the strategy of un-intensive land use in the game playing with the central government, at the same time, they resort their monopoly position in urban land, that lead to inefficient irrational utilization of residential land and industrial land by choosing different strategies for residential land with low elasticity and industrial land with high elasticity. Although the land developers tend to increase the intensive degree of land use, but the actual land area is not conform to its ideal state which cause the loss of the whole efficiency of society about land use. These analyses provide guidance for improving urban land use policies.The eighth chapter is about the policy system of urban land intensive use. This chapter mainly analyzes the policy condition needed for different potential types and behavior decision of managers and developers of urban land. According to opinions of policy implementers and expert inquiry, referencing experience of land intensive use in abroad cities, it integrates the policy systems for promoting urban land intensive use and effective potential exploit, which mainly including changing economic growth mode, remodeling government performance inspection system, improving existing policy system,taking public welfare as core, advocating public participation, strengthening government macro-control, making scientific land use standard, perfecting land purchase and reserve, reinforcing property right management and increasing supply strength of market.Chapter9is conclusion and prospect. This chapter summarizes the whole paper and prospects the future research directions.
