摘　　要：准确把握长江经济带高技术制造业集聚水平和时空演化规律对于科学制定区域产业政策具有重要意义.依据2000—2019年长江经济带沿江11省市高技术制造业的相关数据,运用区位熵和EG指数对高技术制造业集聚水平进行统计测度,利用ArcGIS 10.5工具剖析高技术制造业集聚水平的时空演化趋势.研究表明:(1)从总体来看,在时间上,长江经济带沿江11省市高技术制造业集聚水平呈波动式下降态势,多数省份在全国范围内仍不具备专业化比较优势;在空间上,集聚水平呈自东向西、自沿海向内陆递减的梯度分布态势;(2)从制造业细分行业看,长江经济带沿江11省市高技术制造业EG指数总体呈倒“U”型发展趋势,各细分行业的集聚水平存在显著差异.Accurately grasping the agglomeration level and temporal and spatial evolution law of high-tech manufacturing industry in the Yangtze River Economic Belt is of great significance for scientifically formulating regional industrial policies.Based on the relevant data of high-tech manufacturing industry in 11 provinces and cities along the Yangtze River Economic Belt from 2000 to 2019,the location entropy and EG index are used to statistically measure the agglomeration level of high-tech manufacturing industry,and the ArcGIS 10.5 tool is used to analyze the temporal and spatial evolution trend of the agglomeration level of high-tech manufacturing industry.The research shows that:(1)In terms of time,the agglomeration level of high-tech manufacturing industry in 11 provinces and cities along the Yangtze River Economic Belt shows a fluctuating downward trend,and most provinces still do not have professional comparative advantages nationwide;in space,the agglomeration level shows a gradient distribution trend from east to west and from coastal to inland.(2)From the perspective of manufacturing industry segments,the EG index of high-tech manufacturing industry in 11 provinces and cities along the Yangtze River Economic Belt generally shows an inverted“U”development trend,and there are significant differences in the agglomeration level of each segment industry.
