【摘要】：LED产业是21世纪具有重要前景的高新技术产业。为此,文章以区为基本研究单元来探索上海市LED产业规模发展水平的空间格局,利用变异系数、艾肯森指数以及空间自相关分析等空间统计学方法对上海2006-2015年近10年的16个区(除崇明区)的LED产业进行了动态差异分析,并以此为基础运用ArcGIS和GeoDa095i软件对上海LED产业的空间集聚状况以及空间特征进行了分析,得出了上海LED产业空间分布格局的形成机制和空间演变特征。结果表明:上海LED产业规模呈现出比较显著的空间集聚现象,具有明显的空间依赖性;2006年以后上海LED产业布局先出现高—低集聚与低—高集聚的趋势趋于分散,到2013年以后集聚的趋势得到了加强,空间自相关的聚集趋势也越来越明显,呈现出显著的空间异质性且"L-L"、"H-L"、"L-H"紧密分布在"H-H"空间关联区周围,LED区域产业规模增长的空间差异逐渐显著;LED产业空间集聚呈现出极核—分散式发展分布格局;主要的形成机制因素是政府的政策向导作用,上海科研院所和高等院校的技术保障以及横向相关产业的协同带动作用。
[Abstract]:LED industry is an important high-tech industry in 21th century. Therefore, this paper takes the area as the basic research unit to explore the spatial pattern of the scale development level of LED industry in Shanghai, using the coefficient of variation. Ikenson index and spatial autocorrelation analysis were used to analyze the dynamic differences of LED industry in 16 districts (except Chongming District) in Shanghai from 2006 to 2015. On this basis, the spatial agglomeration and spatial characteristics of Shanghai LED industry are analyzed by using ArcGIS and GeoDa095i software. The formation mechanism and spatial evolution characteristics of the spatial distribution pattern of Shanghai LED industry are obtained. The results show that the scale of Shanghai LED industry presents a relatively significant phenomenon of spatial agglomeration and has obvious spatial dependence. After 2006, the industrial layout of LED in Shanghai first appeared the trend of high-low agglomeration and low-high agglomeration, and the trend of agglomeration after 2013 was strengthened. The trend of spatial autocorrelation is also more and more obvious, showing significant spatial heterogeneity and "L-L", "H-L", "L-H" closely distributed around the "H-H" spatial correlation region. The spatial difference of LED regional industrial scale growth is gradually significant; The spatial agglomeration of LED industry presents the pattern of polar kernel-dispersive development and distribution; The main forming mechanism factors are the policy guidance of the government, the technical support of Shanghai scientific research institutes and colleges and universities, and the synergistic driving effect of horizontal related industries.
