湖南省工业用地利用效率评价分析

工业用地高效利用是城市可持续发展的前提,新型工业化道路是可持续发展的必由之路,当前工业经济高速发展,土地低效利用与环境污染问题日益凸显。该研究基于DEA方法,从环境—经济、投入—产出2个角度建立评价指标体系,以湖南省为例,测度2013—2016年湖南省工业用地利用效率,并运用ArcGIS10.2分别对2013年和2016年工业用地利用效率的空间布局进行分析。得出结论:湖南省工业用地利用效率整体较高,呈上升趋势,各城市之间利用效率有较大差异。空间上,工业用地利用效率存在明显的区域差异,但逐步形成协同发展模式;大部分城市的纯技术效率与规模效率变化不同步,需要进一步探讨两者稳定的发展模式。结合产业类型进行工业结构调整是对工业用地利用效率研究内容的补充及研究趋势。

Evaluation and Analysis of Industrial Land Use Efficiency in Hunan Province

The efficient use of industrial land is the premise of urban sustainable development, while the new industrialization road is the best way for sustainable development. Accompanying with rapid development of industrial economy, the problem of inefficient land use and environmental pollution has become more serious. Based on DEA method, the evaluation index system is set up from the perspectives of environment-economy and input-output. Taking Hunan province as an example, by using four rounds data form 2013 to 2016, the efficiency of industrial land use in the study area has been calculated. The spatial distribution of industrial land use efficiency in 2013 and 2016 has been analyzed by ArcGIS10.2. As showed by the result, the efficiency of industrial land use in Hunan province is high, and it has a rising trend. The efficiency of industrial land use varies greatly between different cities. There are obvious differences in the efficiency of industrial land use in spatially. The efficiency of industrial land use gradually form a coordinated development model. The pure technical efficiency and scale efficiency of most cities are not synchronized, so it is necessary to explore the stable development model. Combining with industrial types, the adjustment of industrial structure is a supplement and a trend to study industrial land use efficiency.
