摘要
创新要素具有明显的地理集聚特征,在当前国际经贸与科技博弈不确定性加剧、国内经济发展方式加快转型的背景下,如何有效促进国内高质量科技成果的扩散与转移,实现高水平科技自立自强是亟待解决的一个重大现实问题。本文以长三角地区战略性新兴产业为研究对象,分析其技术扩散的时空演变格局。在此基础上,立足于中国政府高度参与创新驱动发展的现实,实证检验G60科创走廊建设对地区技术扩散的影响及其作用机制。研究发现:①长三角地区技术扩散的广度和深度不断扩展,呈现出由单中心驱动向多中心互动的演化规律,其中G60科创走廊沿线城市占据一定主导地位。②G60科创走廊建设显著提升了沿线城市的技术扩散能力,特别对上海、杭州等发达城市的促进作用更强。③机制分析表明,G60科创走廊建设主要通过强化政府战略引领、增强经济集聚以及优化创新环境3条渠道推动地区技术扩散。④进一步分析发现,G60科创走廊建设促进了企业间应用性技术以及专有技术的扩散,但没有提升沿线高校、科研院所向企业的技术扩散。本文结论不仅有助于深化理解以G60科创走廊为代表的跨区域协同创新政策对高质量科技成果扩散的作用效果,也为相关政策设计提供了决策支持。
Innovative factors tend to exhibit pronounced geographical clustering.Amidst growing uncertainties in international economic and technological competition and the accelerated transformation of China's domestic economic model,a crucial challenge is to effectively promote the diffusion and transfer of high-quality scientific achievements,thereby achieving high-level technological self-reliance.This paper examines the spatio-temporal evolution of technological diffusion within strategic emerging industries in the Yangtze River Delta.Building on this foundation,and grounded in the Chinese government's strong commitment to innovation-driven development,the study empirically investigates the impact of the G60 Science and Technology Innovation Corridor on regional technology diffusion and its underlying mechanisms.The results show that:(1)The breadth and depth of technology diffusion within the study area continue to expand,following an evolutionary shift from single-centre to multi-centre interactions,with cities along the G60 Innovation Corridor occupying a dominant position.(2)The development of the G60 Innovation Corridor significantly enhances the technological diffusion capacity of cities along its route,particularly in developed cities such as Shanghai and Hangzhou.(3)Mechanism analysis indicates that the corridor primarily promotes regional technological diffusion through three channels:strengthening strategic government guidance,enhancing economic agglomeration(high-tech enterprises and talent),and optimizing the innovation environment(transport infrastructure,financial supply,and openness to external markets).(4)Further analysis reveals that while the corridor facilitates the diffusion of applied and proprietary technologies among enterprises,it does not appear to significantly improve technology transfer from universities and research institutions to enterprises.These findings not only deepen our understanding of how cross-regional collaborative innovation policies,exemplified by the G60 Innovation Corridor,contribute to the high-quality diffusion of scientific and technological achievements,but also provide valuable policy implications for future design.
