长三角城市技术关联演化特征与影响因素分析

Technological relatedness evolution and influencing factors of the Yangtze River Delta cities

技术关联对区域创新和区域经济发展具有显著促进作用,引起了经济地理学者高度关注,长三角创新共同体建设正在加速推进,探究其技术关联演化特征及影响因素具有重要意义。本文以长三角41个地级及以上城市为例,利用2000—2016年发明专利数据,运用共存分析方法分析了长三角城市技术关联的时空演化特征,并重点探讨政府支持、大学能力和企业能力对技术关联演化的驱动作用机制。研究发现:①长三角城市“技术空间”逐步显现,空间格局呈现典型的“核心-边缘”结构,且从相对孤立分散向以合肥-上海-杭州-宁波为核心的“Z”字形空间分布演化。②政府支持、大学能力和企业能力对城市技术关联密度的影响存在显著差异。政府支持的影响作用不显著,企业、大学对城市技术关联密度具有正向促进作用,且企业能力的影响作用更强。③针对不同类型的城市,企业、大学的正向促进作用存在异质性。本研究有助于明晰长三角城市技术关联特征和影响因素,为长三角率先实现科技创新领域高质量一体化提供理论依据,同时,也有利于丰富完善区域创新系统等相关理论体系。

Technology relatedness plays a significant role in promoting regional innovation and regional economic development,which has attracted the attention of economic geographers.The construction of the innovation community in the Yangtze River Delta is accelerating,and it is of great significance to explore its technology relatedness evolution and influencing factors.Taking 41 cities in the Yangtze River Delta as an example,this paper uses the data of invention patent from 2000 to 2016 to analyze the evolution characteristics of the technology-related spatial pattern by co-occurrence analysis methods.At the same time,this article explores the driving mechanism of government support,university capabilities,and corporate capabilities on the evolution of technology associations based on regional innovation system theory.The research found that:①The technology-related spatial pattern of the Yangtze River Delta presents a typical"core-periphery"structure,and has evolved from isolated and scattered to a"Z"-shaped spatial distribution centered on Hefei-Shanghai-Hangzhou-Ningbo.②There are significant differences in the impact of government support,university capabilities,and corporate capabilities on the density of technology relatedness.The driving role of government support is not significant.Enterprises and universities have a positive role in promoting the density of technology relatedness,and the driving role of enterprises is stronger.③For different types of cities,the positive promotion effects of enterprises,universities are heterogeneous.Through this research,it will help clarify technological relatedness and driving factors of the Yangtze River Delta,and provide a theoretical basis for the Yangtze River Delta to take the lead in realizing high-quality integration in the field of scientific and technological innovation.It also help enrich the regional innovation system and other related theories.
