文章根据“企知道”专利微观数据,使用标准差椭圆、相对集聚系数、正六边形格网方法,以国土空间与专利区位空间为参照基准,分析了2009—2020年中国战略性新兴产业专利的大规模空间集聚的水平、形态、模式及变化趋势。结果表明：①中国发明专利总体呈现出向东南移动、集中化与集聚化的趋势,其标准差椭圆面积收缩了14.37%,相对集聚系数增长了8.94%。②中国发明专利总体呈现集中式大规模集聚模式,核心集聚区位于长三角地区——北至江苏盐城、南至浙江温州、西至安徽池州、东至上海。③在8个战略性新兴细分产业中,6个产业的创新呈现集中式集聚模式,其中集聚程度最高的产业为新一代信息技术、数字创意和新能源,集聚程度最低的产业为节能环保,集聚程度由高转低的产业为生物产业。
Based on the patent data of Qizhidao and taking territorial space and patent location space as reference,this paper analyzes the level,shape,mode and trends of large-scale spatial agglomeration of patents in strategic emerging industry of China from 2009 to 2020 using the standard deviation ellipse,the relative agglomeration coefficient,hexagonal grids. The results show: 1) The spatial distribution of patents in strategic emerging industry of China moves southeastward and tends to be more concentrated and agglomerated,with the area of its ellipse declining by 14.37% and the relative agglomeration coefficient increasing by 8.94%. 2) The spatial distribution of patents demonstrates a mode of concentrated agglomeration,with the most extensive concentration lying in the Yangtze River Delta (bordering at Yancheng of Jiangsu in the north,Wenzhou of Zhejiang in the south,Chizhou of Anhui in the west,and Shanghai in the east). 3) Among eight strategic emerging subsectors,next information technology,and digital creativity and new energy show the highest extent of patent agglomeration,energy saving and environmental protection is at the lowest level of patent agglomeration,the biological industry shifts from higher level to lower level of patent agglomeration.
