【摘要】 城市是人类活动的场所,是人类以空间集中形式开垦自然以便于进行生产和消费的载体。城市土地利用效率的高低是关系人类的生活质量和可持续发展的问题,有利于缓解目前我国人多地少、供需突出的矛盾。目前我国正处在经济快速发展、城市化水平调整提升的过程中,一些城市只注重外延的扩张,在利用上存在着粗放利用、土地资源浪费的现象,不同城市土地利用效率差距较大。因此研究城市土地的利用效率,对于提高我国城市土地利用效率、节约土地资源具有重要现实意义。本文通过对已有理论和研究成果的回顾,以四川为例从城市土地利用效率出发,通过对四川各地级城市土地利用的总体情况进行分析,选取2006年四川各地级城市土地利用的截面数据,运用DEA方法对四川城市土地利用的相对效率进行评价,并分别对投入产出指标分析,剖析各城市土地利用效率存在差异的原因,并提出相应的政策建议。研究主要结论如下:(1)对四川各地级城市土地利用现状进行分析,并运用DEA方法进行实证研究,得出四川城市土地利用总体效率不高,土地资源存在浪费的现象。(2)城市土地利用效率与城市规模没有直接的关系,规模较小的城市更容易达到城市土地利用的DEA有效,但这样的DEA有效仅仅只是停留在低层次上的城市土地利用有效。(3)实证研究还表明四川各地级城市土地利用效率不高既有由于投入过多带来的规模报酬递减,也有由于投入不足而导致的土地未能得到充分利用的原因。因此要想进一步提高四川各城市的土地利用效率,需要对各城市的具体情况进行分析,然后进行有针对性的调整,以达到充分利用城市土地的目的。(4)对投入产出指标进行分析,找出四川城市土地利用效率低下的原因,为提高四川城市土地利用效率指明方向。更多还原

【Abstract】 Cities are places of human activity, carriers of carrying out production and consumption by the way of human space concentrating natural land. Urban land using efficiency has high relations between the human quality of life and sustainable development issues, is beneficial to easing the condition of less land and more people, and the obvious contradiction between supply and demand issues in China. At present China is in rapid economic development, some cities only pay attention to the expansion of extension, using extensively the existence, to enhance the level of urbanization in the process of adjustment, by the way of the waste of land resources, the gap of cities’ land-use efficiency is quite large. So there is an important practical significance on studying the urban land using efficiency, for improving the urban land using efficiency, and conserving land resources in China.Based on existing theory and research results of the review, taking an example of urban land using efficiency in Sichuan Province, through analyzing the overall land-use situation of the cities around Sichuan, selecting the section of data of the cities’ land-use situation around Sichuan in 2006, the paper used the way of DEA to evaluate Sichuan urban land using overall efficiency, and analysed the reasons for the differences of various urban land using efficiency by construing the input-output indicators analysis of and analysis of, and made appropriate policy recommendations.The main conclusions of study are as follows:(1) Through analysing actuality of the cities’ land using around Sichuan Province and using of DEA empirical research, the overall land using efficiency of the cities in Sichuan is not high. There are still wastes of land resources in the phenomenon.(2) There are not directly relations between the urban land using efficiency and the size of the cities, the smaller cities are more easily in the best condition of the urban land using, but this condition is at the low level of urban land using efficiency.(3) Empirical studies also show that the Sichuan-class cities’ land-use efficiency is not high, which is due to the reasons of the diminishing returns for the excessive investment scale of, and the land has not been fully utilized as a result of inadequate input of reasons. So in order to further improve the city’s land-use efficiency in Sichuan, the analysis of the specific circumstances of each city are required and then proceed to a targeted adjustment to achieve the objective of making full use of urban land.(4) Through analysing respectively on the input-output of indicators to identify the impact factors of the Sichuan-class urban land using efficiency, the direction to enhance the efficiency of urban land using in Sichuan was specified.更多还原
