| 摘 要： | 本文通过计算2000-2008年我国IT产业的市场集中度指数及空间集聚β指数,来考察IT产业的集聚现象;并进一步运用空间计量方法,计算出Moran指数及其散点图,来分析产业集聚的空间相关性和空间分布特征。结果表明,我国IT产业发展的不平衡性在逐渐加剧,IT产业呈现出在少数几个省区集聚的现象,具有明显的地方化现象。我国IT产业属于高度空间集聚产业,且空间集聚指数逐年增大,产业集聚现象明显。我国IT产业发展水平及其增长的空间分布不是随机的,而是在全局和局域环节都呈现出正向的空间依赖特征,表现为高发展水平的区域倾向于集聚在一起。

| Abstract: | This paper is to analyze the concentration phenomenon of IT industry based on the market concentration index and space concentration β index with data through 2000-2008.With the help of space metering method,we get the Moran index and scatter diagram to analyze the space relativity of industry concentration and space distribution characteristics.The findings show that the development imbalance of IT industry is increasing and it takes on localization in several provinces.IT industry in China is highly-concentrated with increasing space concentration index.Furthermore,it takes on positive space-depending character rather than casual one. |
