Abstract

The shadow and spillover effects of large cities are critical for achieving balanced regional economic development. However, empirical studies that explore how major cities influence the innovation growth of their neighboring cities are scarce. This study employs panel data from Chinese cities covering the period from 1996 to 2018 to empirically assess the impact of proximity to cities with comparative innovation advantages on local innovation growth. Our results reveal that until 2005, proximity to innovative core cities negatively affected local innovation growth. This adverse effect gradually diminished over time, becoming significantly positive after 2010. Furthermore, the advent of high-speed rail has played a pivotal role in mitigating the negative impacts of nearby innovative core cities. These findings offer fresh insights into regional innovation ecosystem dynamics and underscore the transformative role of infrastructural developments in bolstering urban innovation capacities.

影子与溢出：邻近创新型城市对区域创新增长的影响

大城市的影子效应和溢出效应对实现区域经济均衡发展至关重要。然而，主要城市如何影响周边城市创新增长的实证研究却很少。本研究采用1996 - 2018年中国城市的面板数据，实证评估了邻近比较创新优势城市对地方创新增长的影响。研究结果表明，直到2005年，靠近创新核心城市对当地创新增长产生了负面影响。随着时间的推移，这种不利影响逐渐减弱，在2010年之后变得明显积极。此外，高铁的出现在缓解附近创新核心城市的负面影响方面发挥了关键作用。这些发现为区域创新生态系统动态提供了新的见解，并强调了基础设施发展在增强城市创新能力方面的变革性作用。
