以广州市新增“工程和技术研究与试验发展”企业数量为例进行空间分布特征分析,并进行正态分布检验,Global Moran’s I指数统计分析结果表明广州市此类新增企业区域分布是随机分布;通过Local Moran’s I指数和Moran散点图进一步刻画了新增企业的局部空间模式及时空演进态势,表明其有聚集分布的趋势。通过这类方法对广州市其他重点行业进行区域集聚度分析,可以为制定产业政策提供依据,从而加速产业集聚,带动城市发展。
Taking the number of new “engineering and technology research and development” enterprises in Guangzhou as an example, the spatial distribution characteristics were analyzed and the normal distribution test was conducted. The results of Global Moran’s I index statistical analysis showed that the distribution of such new enterprises in Guangzhou Are randomly distributed. The local spatial patterns and spatial-temporal evolution of new enterprises are further described by Local Moran’s I Index and Moran Scatter Plot, indicating that they have the trend of aggregation and distribution. Through such methods, the analysis of regional concentration of other key industries in Guangzhou can provide the basis for formulating industrial policies so as to speed up industrial agglomeration and promote the development of cities.
