长三角地区城市创新关联及其隐性壁垒研究

Research on the Urban Innovation Correlation in the Yangtze River Delta and Its Implicit Barriers

城市创新关联是创新主体合作和知识溢出的空间路径之一,有效地驱动长三角高质量一体化发展。选取专利合作数据,运用社会网络分析和二次指派程序方法探究长三角地区城市创新关联事实及其隐性壁垒。研究结果表明:长三角确实存在城市创新关联现象,呈现逐步深化特征,证实了国家推动长三角一体化战略符合经济社会演化客观需求。随着产业链升级和更大范围空间组织优化,长三角城市创新关联仍然不足,产业关联、交通地理和文化差异成为重要隐性壁垒。研究结果启示,应进一步完善高铁线路压缩长三角"中心"与"外围"的交通地理;产业转移或选址过程中应优先产业和技术基础相似地区布局,强化产业关联性群集;在毗连地区建立更广泛的认同感、信任感和归属感,共同驱动创新关联的高质量一体化发展。

The correlation of urban innovation is a spatial path for innovation cooperation and knowledge spillover, effectively driving the high-quality integrated development of the Yangtze River Delta region.Based on the patent cooperation data, this paper uses SNA and QAP methods to explore the facts and hidden barriers of urban innovation in the Yangtze River Delta region. The research results show that the Yangtze River Delta does have the phenomenon of urban innovation correlation, showing gradual deepening characteristics, which confirms that the country’s promotion of the Yangtze River Delta integration strategy meets the objective needs of economic and social evolution. With the upgrading of the industrial chain and the optimization of the wider spatial organization, the innovation linkages of the Yangtze River Delta cities are still insufficient, and industrial linkages, traffic geography and cultural differences have become important hidden barriers. The research results suggest that the high-speed railway line should be further improved to compress the "center" and "peripheral" traffic geography of the Yangtze River Delta;in the process of industrial transfer or site selection, priority should be given to the layout of similar industries and technical bases, and industrial clusters should be strengthened;A broader sense of identity, trust and belonging, together drive the high-quality integrated development of innovation.
