摘要
创新驱动发展战略推动经济地理格局从产业集群转向创新集群,传统以地理距离为边界的区域发展格局被逐渐打破,中心与外围城市之间技术互补关系逐渐成为主导。本文运用技术复杂度和城市间技术互补指数对创新集群中心城市和外围城市进行重新识别,并对互补性技术体系下创新集群中心—外围的经济增长收敛性进行深入分析。研究发现,创新集群中心—外围经济发展差异呈现不断缩小的特征;中心与外围城市间技术互补促进了创新集群经济增长的绝对β收敛和条件β收敛趋势,并存在显著的空间效应;创新集群中心—外围技术结构呈现从技术竞争向技术互补的转变,中心与外围城市技术竞争对创新集群经济增长收敛具有抑制作用;外围城市协同式创新水平和倾向的提升有利于提高创新集群中心—外围技术互补程度。这些经验证据的政策含义是转变区域发展思路,实现从以地理半径为导向到以技术半径为导向的逐渐转变,增强城市间、都市圈与城市群内外部城市的技术互补,赋能创新集群中心城市,在更大地理范围内实现城市间技术分工与合作,推动区域高质量协调发展。
In China,an innovation driven development strategy has encouraged the transformation of the existing economic geographical pattern from industrial clusters to innovation clusters.The traditional regional development idea,with geographical distance as the boundary,is gradually being broken.For example,there has been a change in the relationship between central cities and peripheral cities,from a driving role and one based on technological competition,to one of technological complementarity.However,few studies have investigated the central and peripheral cities of innovation clusters.There are also few studies that have explored the evolution of technological structure between the central and peripheral cities of innovation clusters,and the convergence of economic growth.This paper redefines the central and peripheral cities of innovation clusters,by focusing on technology complexity and the inter-city technology complementarity index.The study applies the innovation cluster center and peripheral city economic development difference index,βconvergence model,and spatial panel econometric model to deeply analyze the convergence of economic growth of innovation cluster central and periphery cities under a complementary technology system.The study reveals the following findings.There has been a narrowing of the difference in economic development between the innovation cluster center and the surrounding cities.The level of technological complementarity has increased when comparing the central city and the peripheral cities of innovation clusters,accelerating absolute economic growth of the two cities.This is demonstrated by the absoluteβconvergence and conditionalβconvergence trend.The results have a significant spatial effect.Based on the evolution of the technological structure of the innovation cluster center and periphery cities,as time passes,the technological complementarity between the center and periphery cities increases.In contrast,technological competition first rises and then falls.That is,the technologic
