中国城镇建设用地投入效率的空间分异研究

基于对城镇建设用地投入效率概念与内涵的理解,从投入产出水平、区际关系、载荷容量、人地关系等视角构建评价指标,从效率水平和人工复合生态系统内在耦合协调性组织内容,并结合均方差赋权法对我国30个省（自治区、直辖市）进行实证研究。结果表明：①该评价体系既能够较为全面反映公平与效率、制度安排效应,也能用于检验区域系统内部经济—社会—生态环境的耦合协调性,实用性强;②我国城镇建设用地投入效率呈现出的特征：水平特征——粗放、低效增长,复合生态系统处在低水平的耦合协调阶段,空间特征——分异明显,其中经济效率的空间分异最为明显,而区域四分法大体呈由东往西依次递减的地理格局;③我国城镇建设用地投入效率的空间分异在一定程度上映射了国家宏观发展战略相对注重社会公平而忽视效率、政府绩效考核体系对其投入效率的影响等。

Study on the Spatial Differentiation of Urban Construction Land Input Efficiency in China

Based on the understanding of the essence of urban construction land and the efficiency of urban construction land input,this paper,from the input and output level,interregional relations,load capacity,human-land relationship perspectives and so on,built the efficiency evaluation indexes of urban construction land input,from benefit levels and the coupling coordination of the artificial composite ecological system perspectives,organized the contents,and then,connecting with the weighting variance method,used our country 30 provinces(autonomous region,municipality directly under the central government) to do an empirical research.The result shows that:(1) the efficiency evaluation system on the urban construction land input can effectively use in China’s empirical analysis,in the article the result of empirical analysis is coincide with the practical situation very well.The efficiency evaluation system implies equity and efficiency,the system arrangement effect.It is also can use to test the coupling coordination of regional system internal economic-social-environment,and then give some reasonable advices.(2) The characteristics of our country urban construction land input efficiency as follow:the level characteristics—inefficiently and extensively growth,the composite eco-system is still staying at low coupling coordination degree level;the space characteristics—spatial differentiation is obvious.Comparing with the spatial differentiation on economic efficiency,social efficiency and environment efficiency,we got conclusion that the economic spatial differentiation is the most obvious one,and all of them basically formed a geographic patterns that the spatial differentiation from east to west is going to decrease.(3) The spatial differentiation of our country urban construction land input efficiency,to some degree,reflects the facts that national macro development strategy relatively attaches important to social fairness than efficiency,and the government performance evaluation system have an influence on the efficiency of urban construction land input.
