摘要
发展新质生产力是中国顺应新一轮科技变革的时代要求,而城市创新合作则是实现这一目标的关键途径。本研究基于2011—2023年中国279个地级及以上城市面板数据,从空间视角切入,实证检验城市创新合作对新质生产力的影响效应及机制。研究发现:城市创新合作不仅能显著提升本地新质生产力,还能通过空间溢出效应带动邻近城市新质生产力的发展。这一过程主要通过强化城市网络效应、驱动产业技术创新以及激发市场活力实现,同时,上述机制对近邻城市亦存在正向空间溢出。异质性检验发现,东部地区城市创新合作对本地及邻近城市新质生产力均显著为正;中部仅推动本地新质生产力发展;而西部和东北地区则对近邻城市存在虹吸效应。此外,大城市与中心城市的创新合作表现出明显的正向溢出,而中小城市和外围城市则未能产生类似效应。本研究为借势区域创新联动推动新质生产力的发展提供了理论支撑和政策启示。
Developing new quality productive forces represents China's strategic response to the demands of a new round of technological revolution,with intercity innovation cooperation serving as a key pathway to achieve this goal.Based on panel data from 279 Chinese cities spanning 2011 to 2023,this study quantitatively evaluates the levels of urban innovation cooperation and new quality productive forces,and investigates the impact and underlying mechanisms of innovation cooperation from a spatial perspective.The findings reveal that urban innovation cooperation not only significantly enhances local new quality productive forces,but also promotes their development in neighboring cities through spatial spillover effects.Specifically,innovation cooperation empowers local productivity by strengthening urban network effects,driving industrial technological innovation,and stimulating market vitality.These benefits extend spatially,enhancing the network efficiency,industrial innovation,and market dynamics of adjacent cities,thereby facilitating a regional leap in new quality productive forces.Heterogeneity analysis shows that innovation cooperation in eastern cities significantly promotes new quality productive forces both locally and in neighboring areas.In contrast,central cities show strong local effects but lack spatial spillovers.Western and northeastern cities improve local productivity but exert a siphoning effect on surrounding areas.Moreover,large and central cities exhibit a clear'first-mover advantage,'with their innovation cooperation generating strong positive spillovers,whereas small and peripheral cities do not display similar effects.This study provides theoretical support and policy insights for the Chinese government to accelerate the development of new quality productive forces through regionally coordinated innovation in the new era.
