基于“两型社会”的武汉城市圈土地集约利用评价

以获批全国"两型社会"建设综合配套改革试验区的武汉城市圈为研究对象,以"资源节约和环境保护"为目标,综合考虑土地集约利用的环境、社会、经济效应,阐述了土地集约利用的内涵,依据投入-产出等理论,构建了武汉城市圈土地集约利用评价体系,利用数据包络分析(简称DEA)法,对武汉城市圈土地集约利用进行了评价。研究结果表明:①武汉城市圈中仅有武汉、仙桃、天门三个城市是DEA有效的,DEA无效的6个城市DEA有效性从高到低分别是为黄冈、孝感、潜江、咸宁、鄂州、黄石;②影响武汉城市圈中城市DEA无效的因素是多样的,但主要集中在固定资产投资和单位GDP能耗等投入过多,GDP、社会商品销售额、财政收入、就业人员、生活垃圾处理率等产出率低。文章根据评价结果结合实际情况分析并指出了武汉城市圈发展过程中出现的土地利用问题,进而探讨"两型社会"框架下武汉城市圈应如何集约利用土地,优化配置土地资源,以实现"资源节约和环境保护"的目标。

Evaluation on Intensive Land Use of Wuhan Urban Agglomeration Based on “Two-oriented” Society

The purpose of this paper is to build connotation and evaluation framework of intensive land use for Wuhan urban agglomeration based on "two-oriented" society(resource-conserving society and environmertal-friendly society) and input-output theories.Methods of documentation method and data envelopment analysis were employed.The results indicate: ① Wuhan,Xiantao,Tianmen in Wuhan urban agglomeration have DEA efficient,the other six cities that have DEA inefficient from high to low are Huanggang,Xiaogan,Qianjiang,Xianning,Ezhou and Huangshi.② The influence factors of DEA inefficient for cities in Wuhan urban agglomeration are mainly concentrated on excessive input in fixed asset investment and unit GDP energy consumption and low output in GDP,sales of social commodities,revenue,employment and garbage disposal rate,etc.According to the analysis of the evaluation result and practical situation,this paper points out the land use problems in Wuhan urban agglomeration,then discuses how to intensively use land and optimize the allocation of land resources to achieve the goal of resource conservation and environmental protection under the "two-oriented" society.
