【摘要】 区域新技术活动的产生与演化是经济地理学的经典命题。本文以长三角地区为案例，基于2000—2020年中国411.91万件授权发明专利，从技术关联性视角出发探究本地知识基础、区域间补充性联系及两者交互作用对突破性创新的影响。研究发现：(1) 2000—2020年长三角地区突破性创新水平不断提升，地理分布呈现出显著的核心-边缘结构。突破性技术创新领域从早期以传统工业为主转变到以知识密集型产业和高新技术产业为主。(2)技术非关联性是长三角地区突破性创新的核心驱动力，能够显著促进突破性技术在新领域的进入和已有领域的增长，而技术关联性对突破性技术进入具有显著负向作用。(3)区域间补充性联系能够促进突破性技术进入和增长，但并不一直具备积极作用，补充性联系和技术关联性的交互作用阻碍了突破性技术的进入。本文的贡献在于探究了补充性的外部联系在区域突破性技术产生和发展中的作用，该研究能够为长三角地区及其他区域发展突破性技术创新提供政策启示。更多还原

【Abstract】 The generation and evolution of regional new technological activities is a classic proposition in economic geography. Taking the Yangtze River Delta region as a case study, this paper explores the impact of local knowledge base, inter-regional complementary linkages and their interactions on breakthrough innovations from the perspective of technological relevance, based on 4,119,100 granted patents in China from 2000 to 2020. The study finds that:(1) The level of breakthrough innovation in the study area had been increasing from 2000 to 2020, and the geographical distribution showed a significant core-edge structure. Moreover, the focus of breakthrough technological innovation has shifted from the traditional industries that met the basic societal needs of the society in the early stage to the knowledge-intensive and high-tech industries.(2) Technological unrelatedness is the core driving force of breakthrough innovation in this region, which can significantly promote the entry of breakthrough technologies in new fields and the growth of existing fields, while technological relatedness has a significant negative effect on the entry of breakthrough technologies and has no significant effect on the growth of these technologies.(3) Although interregional complementary linkages can foster the entry and growth of breakthrough technologies, their effect is not always positive. In fact, the interaction between complementary linkages and technological relatedness can hinder the entry of such technologies. The contribution of this paper is to explore the role of complementary external linkages in the generation and development of breakthrough technologies in the region, and the study provides policy implications for the development of breakthrough technological innovations in the Yangtze River Delta and other regions.更多还原
