| Land resources is the foundation of human survival and development and thecarrier. To realize the sustainable use of land resources must improve the existing landuse efficiency. At present, the construction of a conservation-minded society is animportant national policy in China, land resources, as a kind of important resourcesand assets, need more intensive conservation. Urban construction land is the carrier ofurban and regional economic development, economic development and urbanconstruction land use is reasonable is an important basis, to a large extent depends onthe efficiency of utilization of the urban construction land. Therefore, how to establisha set of complete index system to evaluate the overall economic efficiency of landutilization, and improve the use efficiency of construction land is an importantresearch topic.This article aims to build a set of exploratory and strong operability evaluationindex system, the collection of14cities in guangxi in2006-2006to use constructionland on the basis of economic efficiency index of related data, the selection of theguangxi zhuang autonomous region as the object of empirical study, using dataenvelopment analysis (DEA) method), and C squared R dual model, with the help of aDEAP Version2.1software, the construction land use of14cities in guangxieconomic efficiency from the vertical and horizontal two dimensions are compared,and analysis and quantitatively reflect the GuangXiOu municipal construction landuse level of economic efficiency, so as to provide reference for policymakers topromote urban land use transforming to intensive way is more extensive.Paper to compare from the horizontal dimension of14cities in guangxiconstruction land using score of economic efficiency, have seven cities belong toDEA effective in2006, seven cities belong to non DEA effective;2007,2010,2011annual average have nine cities belong to DEA effective, five cities belong to nonDEA effective; Have eight cities belong to DEA effective in2008, the six citiesbelong to non DEA effective; In2009has10cities belong to DEA effective, fourcities belong to non DEA effective. Paper then from vertical dimension to the analysisof14cities as the sixth year in a row to use construction land economic efficiencychange trend, has six years in a row benefits worth divided into1city, liuzhou, guilin, hechi city, congzuo city; Five years efficiency score for1city: shen; Have four yearsefficiency score for1city, nanning and baise; Efficiency score for1city: three years,wuzhou, guigang and visitors; Efficiency score for1city two years: the passengersand QinZhouShi; Only1year efficiency score for1city: yulin city and He Zhoushi.This paper includes six chapters. First introduced the research background andsignificance, domestic and foreign research review, research contents and methods,and thesis structure and the technical route; And explain the relevant basic concepts,the introduction of several major theoretical basis: the law of diminishing returns ofland, rent of land theory, location theory, theory of sustainable land use; The third partis the construction land use economic efficiency evaluation method choice, namely,choose DEA method is applied to construction land use of economic efficiencyevaluation. Comparing to the traditional method is commonly used in first, thenaccording to DEA method, a detailed introduction, definition, model, mathematicalprinciples and applications, etc., sums up the application of DEA method to study thefeasibility of this thesis and advantage. The fourth part is based on the DEA method,the evaluation index system of building, the first step is the analysis and evaluationprocess, then in this paper, the principle of establishing evaluation index system, thechoice of evaluation index factor, as well as the evaluation index system of input andoutput to determine; Empirical research part, first introduced the study area of naturalgeography and economic and social development in guangxi, and land resourcesutilization in2011, then the data collection process and software running calculation,obtains the pure technical efficiency and scale efficiency of decision making units andthe comprehensive efficiency values, focus on comparison and analysis of the guangxi14cities as the economic efficiency of the construction land use of horizontal andvertical change trend, and puts forward the corresponding construction land efficientand intensive conservation recommendations; The sixth chapter is conclusion andprospect. Part summarizes the full text, conclusion and prospect this direction to bestudied in the paper. |
