空间表征学习:对长三角新质生产力创新群落的研究及发现

SPATIAL REPRESENTATION LEARNING:RESEARCH AND DISCOVERIES ON INNOVATION CLUSTERS OF NEW QUALITY PRODUCTIVE FORCES IN THE YANGTZE RIVER DELTA

新质生产力强调创新在引领新发展中的主导作用,以及战略性新兴产业在构筑先进生产力质态中的重要地位。运用表征学习算法,针对长三角专利数据中的国民经济行业分类关联网络,发掘包含新一代信息技术产业、高端装备制造产业、新材料产业、生物产业、新能源汽车产业、新能源产业、节能环保产业、数字创意产业和新兴服务业的九大战略性新兴产业门类的典型创新群落,并通过与各城市自身结构的对比,解析以创新为主导的新质生产力空间分布特征。研究发现:(1)战略性新兴产业在长三角形成了不同类型的产业创新群落空间,典型空间形态有中心辐射式、条带均衡式和分片组团式等;(2)长三角趋于形成一个面向内陆的“E”字型产业创新群落高值连绵区域;(3)上海-苏州-无锡构成了一个“上苏锡”多产业复合创新群落的同质空间。通过对战略性新兴产业创新群落空间表征学习研究,进一步加深了对新质生产力空间特征的认知,为构建高质量区域创新策源和推动长三角一体化空间发展提供了有力支撑。

New quality productive forces emphasize the vital role of innovation in leading new developments and the critical role of strategic emerging industries in building advanced productivity.This paper uses a representation learning algorithm to explore the typical innovation clusters of nine strategic emerging industries,including the new generation of information technology industry,high-end equipment manufacturing industry,new material industry,biology industry,new energy vehicles industry,new energy industry,energy saving and environmental protection industry,digital creative industry,and emerging services industry,by the national economic industry classification association network constructed from the Yangtze River Delta patent data.By comparing the structure of each city,the paper analyzes the spatial distribution characteristics of innovation-led new quality productive forces.It finds that:(1)strategic emerging industries have formed different types of industrial innovation clusters in the Yangtze River Delta,including a)central-radiating type,b)strip-balanced type,and c)fragmented cluster type;(2)the Yangtze River Delta tends to form an E-shaped high-value continuous innovation cluster area facing inland;(3)Shanghai-Suzhou-Wuxi forms a cross-city homogeneous industry innovation cluster space.The study of spatial representation learning of strategic emerging industry innovation clusters deepeneds the understanding of the spatial characteristics of new quality productive forces,providing strong support for building high-quality regional innovation sources and promoting the integrated spatial development of the Yangtze River Delta.
