Study On Driving Factors Of Urban Construction Land Expansion In Hangzhou City

Urban construction land is the objective carrier of social economic activity. With the fast development of economy and the deep promotion of urbanization process, the expansion of urban construction land is asked to meet the needs of economic development. As the deputy center city of the Yangtze River delta economic circle, the level of economic development of Hangzhou improve significantly and continuously, so as the urban construction land expansion.In consequence, it not only brought a series of significant negative effects, but also led to the increasing contradiction of land supply and demand. Therefore, there is vital strategic and practical significance to know how to improve the intensive utilization of urban construction land, to guide reasonable disposition of urban construction land, and to facilitate rational expansion of urban construction land.The thesis makes the study from the view of theory and positivism. In theory research, on the base of the summary of the researches on the driving mechanism, spatial pattern, the control of growth and the scale of urban construction land at home and abroad, the thesis makes a concept definition of the urban construction land and the expansion of urban construction land; briefly discourses upon the main content of agglomerate economy theory, theory of land rent and price, location theory and the core-edge theory and its guiding significance to my study. In positivism research, taking Hangzhou for the research object, the thesis firstly analyzes the typical characteristics of the expansion of urban construction land, secondly makes the quantitative analysis to the inside and outside driving factors of the expansion of urban construction land, and finally proposes the relative countermeasures on reasonable guidance and effective control of the expansion of urban construction land. The author draws the following conclusions through the researches above:(1) The form of expansion of urban construction land in Hangzhou is gradually changing from single-center-edge to polycentric-synergy; per land-gross product of urban construction land is on the rise; the expansion of urban construction land in Hangzhou is of a rapid growth type; and the structure of urban construction land-use in Hangzhou tends to be reasonable gradually.(2) The external driving factors of urban construction land expansion of Hangzhou are the macro gross of national economy, overall consumption of national economy, the urbanization of industrial structure, the urbanization of population and the growth of population; the internal driving factors reflect as the expansion of public lands and commercial-living-industrial lands.(3) The inner link and 5 different types of corresponding modes exist among the 7 internal and external driving factors; multivariate combination correspondence analysis indicate that the internal and external driving factors work with different emphasis in different periods of urban construction land expansion in Hangzhou; economic development, the urbanization process and their coupling function are the main driving factors of urban construction land expansion in Hangzhou; the promotion of population increase on expansion of urban construction land are fairly weak; the effects and influences of policy and institution cannot be ignored.According to the conclusions above, putting forward three countermeasures and suggestions as follows:to promote the connotative expansion of urban construction land, to speed up the construction of the market-regulation-cored urban construction land expansion control system, to implement the total amount control and differential control of the urban construction land expansion, in order to providing useful references to control the urban construction land scale of Hangzhou and guide it to rational expansion, meanwhile, to realize the layout optimization and intensive efficient utilization of urban construction land.
