摘要
基于1985—2020年长三角地区专利数据,通过引用模型研究多维邻近性对六个都市圈在长三角地区创新扩散的影响以及六个都市圈创新扩散和合作的空间格局。研究结果发现:认知邻近性和关系邻近性水平越高,都市圈创新扩散速度越快,而技术邻近性和地理邻近性负向影响了部分都市圈的创新扩散。六个都市圈的创新扩散与合作呈"核心—边缘"的空间结构。上海大都市圈和南京都市圈在长三角创新一体化发展中发挥着举足轻重的作用。
Based on the patent data of Yangtze River Delta region from 1985 to 2020,this paper studies the impact of multi-dimensional proximity on innovation diffusion of six metropolitan areas in the Yangtze River Delta region by following the citation model,with a study of the spatial pattern of innovation diffusion and cooperation of six metropolitan areas in the Yangtze River Delta region.Studies find that the higher the level of cognitive proximity and relational proximity,the faster speed of the innovation diffusion in metropolitan areas,and technological proximity and geographical proximity negatively affect innovation diffusion in some metropolitan areas.Innovation diffusion and cooperation in the six metropolitan areas present a spatial structure of"core-edge"pattern.Shanghai metropolitan area and Nanjing metropolitan area play an important role in the innovation integration development of the Yangtze River Delta.
