基于GIS的中国钢铁企业时空演变格局研究

Research on the Time and Space Evolution Pattern of Chinese Iron and Steel Enterprises Based on GIS

以1916—2008年中国钢铁企业数据为基础,基于GIS技术,利用区位熵、空间自相关方法对我国钢铁企业分布格局分阶段进行研究。研究表明:在时间尺度上,近100年来我国钢铁企业布局的集中度逐渐降低,大型企业市场影响力不足,中小企业数量过多;在空间格局上我国钢铁企业逐渐由东部向中西部地区扩散,集中度东高西低。

Based on the data of China’s steel and steel enterprises from 1916 to 2008 and the GIS technology,the location entropy and spatial autocorrelation method were used to study the distribution pattern of China’s iron and steel enterprises in stages.The research shows that on the time scale,the concentration of steel enterprises in China has gradually decreased in the past 100 years.The market influence of large enterprises is insufficient,and the number of small and medium-sized enterprises is too large.In the spatial pattern,China’s iron and steel enterprises gradually spread from the east to the central and western regions.Concentration is high in the east and low in the west.
