摘　　要：合理的产业类型选择与产业布局形态,对于区域经济高质量发展具有重要影响。以长江经济带2006和2018年省级以上开发区为例,通过主导产业字段提取,构建主导产业语料库,利用文本挖掘方法对其主导产业的类型演化进行分析。在产业分类的基础上,利用核密度、最邻近指数对不同产业发展类型的空间格局演化进行分析。结果发现:①机械与装备制造长期保持主导产业核心地位,同时高附加值产业和新兴产业发展迅速,传统产业地位下降,产业升级态势明显。②国家级开发区是区域产业转型升级的关键引领,东中西部区域间产业分工有所优化。③产业布局的空间集聚特征显著,但表现出由东部向中西部地区扩散与城市群协同发展的趋势。④不同产业发展类型的空间集聚形态与扩散路径存在差异,劳动密集型产业的扩散强度最大,战略性新兴产业最弱。Reasonable industry selection and layout have an significant impact on the regional high-quality development.Taking national and provincial development zones of the Yangtze River Economic Belt in 2006 and 2018 as the research object,this study extracts the leading industry field as the information source to construct the database of text corpus and analyzes the evolution of leading industry type by the method of text mining.Based on the industry classification,it analyzes the spatial evolution of different industrial development types by the means of the kernel density and the average nearest neighbor index(ANNI).The results show that:1)Machinery and equipment manufacturing always maintain a leading position,while high value-added industries and emerging industries develop rapidly and the status of traditional industries decline,the phenomenon of industrial upgrading is obvious.2)National development zones play a key role on the conversion and upgrading of regional industries,and the industrial division of labor has been optimized in the east,middle and west of the Yangtze River Economic Belt.3)There is a significant spatial agglomeration of the industrial layout,but it shows the coordinated development of urban agglomeration and a trend of diffusion from the eastern region to the central and western regions.4)The spatial agglomeration patterns and diffusion paths are different among various industrial types.The diffusion intensity of labor-intensive industries are the strongest,while strategic emerging industries are the weakest.
