How Does Digital Technology Reshape the Boundaries of Intercity Innovation Collaboration? Evidence From China
使用中国2012-2019年城市间合作专利数据，通过负二项回归模型发现数字技术显著促进城际创新合作，尤其能跨越地理距离和城市等级壁垒，对政策制定者推动包容性区域发展有参考价值。
ABSTRACT Empirical studies have rarely explored the relationship between digital technology adoption and transregional innovation collaboration at the city level. To address this important research gap, we use the negative binomial regression model to identify the impact of digital technology adoption on intercity innovation collaboration, with particular emphasis on the reshaping effect of digital technology on geographical and city hierarchical boundaries. The panel data pertains to intercity co‐patents spanning the period from 2012 to 2019 in China. Our findings show that digital technology adoption significantly enhances intercity innovation collaboration. The positive relationship becomes even stronger as the geographical distance between cities increases. Furthermore, digital technology adoption strengthens innovation collaboration not only among first‐tier cities but also between first‐tier cities with second‐ and third‐tier cities. These results suggest that digital technology can effectively bridge geographical distances and break city hierarchies to a limited extent. These insights can inspire policymakers to harness the power of digital technology to reshape the boundaries of intercity innovation collaboration for inclusive regional development.
