The Structure Of Urban Land Use Efficiency Evaluation And Optimization Of Research In Sichuan Province

Urban land was based in urban social and economic development,on a variety of resource allocation in the city carrier,also the most dynamic,value-added potential for the largest state-owned assets,the Government can direct the efficient operation of capital vector.The structure of urban land within the city the proportion of the various functional sites,the spatial structure and their impact on the relationship between role Evaluation of the efficiency of urban land use structure can promote the rational use of urban land,urban land use structure from the efficiency point of view the largest urban land use structure optimization for the future urban planning and urban land-use planning advice.It was used regulating and empirical research,qualitative analysis and quantitative analysis of a combination of research methods In this paper.The Quantitative analysis is for evaluate the structure of urban land use efficiency of Sichuan Province.The various types of urban land as inputs,the social,economic,and ecological as outputs.Finally,it is to draw the structure of optimal adjustment of the direction and recommendations in Sichuan Provincefrom the perspective of maximizing the efficiency of urban land use.With a view to the rational use of urban land in Sichuan Province for reference.(1) Overall,the structure of urban land use efficiency is increasing from 1998 to 2006 in Sichuan Province,but the proportion of DEA efficient units lower than non-DEA efficient unit proportion;all regional urban land use the structural efficiency is relatively low,DEA efficiency between 0.2-0.1,but the efficiency of the various differences between regions are also evident.Chengdu plain and mountainous of northern Sichuan is the low efficiency of urban land use in the more than 0.6,hilly area in southern Sichuan and the western Sichuan Plateau alpine areas the efficiency of urban land use structure in between 0.2-1,Sichuan hilly area of urban land use structure the least efficient.(2) In this paper,to maximize efficiency based on DEA's point of view,put forward the various regions of Sichuan and urban land use structure optimization recommendations. DEA in relatively effective as a reference unit,a relative optimization of Sichuan urban land use structure and the various regional urban land use structure optimization recommendations.(3) The industrial structure,degree of urban land markets,public management of urban land in Sichuan Province and other factors are the structure of the efficiency of urban land use impact.By adjusting the industrial structure to optimize the structure of urban land use,urban land use structure to improve efficiency;improve the flow of urban land markets can also optimize the structure of urban land use;public management of urban land market to make up for the shortcomings of self-regulation,the further optimization of urban land use...
