技术生态位对长三角G60科创走廊创新效率的影响

Impact of Technology Niche on the Innovation Efficiency of G60 S&T Innovation Corridor in the Yangtze River Delta

G60科创走廊是实施长三角一体化战略的重要载体。基于2012—2021年地级市面板数据,构建双向固定效应模型和空间杜宾模型,考察技术生态位的宽度和重叠度对G60科创走廊各城市创新效率的直接影响及空间溢出效应。结果表明,不相关技术的生态位宽度与各城市创新效率显著负相关,相关技术的生态位宽度显著提升创新效率,整体上技术生态位宽度增加不利于创新效率提升;技术生态位重叠度对创新效率具有显著促进作用;在空间效应方面,技术生态位宽度存在显著的负向空间溢出,技术生态位重叠度则显著正向空间溢出。为实施G60科创走廊高质量协同创新、推动长三角创新一体化战略提供理论参考和借鉴。

G60 S&T Innovation Corridor is an important carrier for the implementation of the integration strategy of the Yangtze River Delta.Based on the panel data of the cities at the regional level from 2012 to 2021,the bidirectional fixed-effect model and spatial Durbin model are constructed to investigate the direct impact and the spatial spillover effect of the width and overlap of technology niche on the innovation efficiency of the cities in the G60 S&T Innovation Corridor.The results show that the niche width of unrelated technologies is negatively correlated with the innovation efficiency of each city,and the niche width of related technologies significantly improves the innovation efficiency.On the whole,the increase of technology niche width is not conducive to the improvement of innovation efficiency.Technology niche overlap has a significant effect on innovation efficiency.In terms of spatial effect,the technology niche width has a significant negative spatial spillover effect,while the technology niche overlap has a significant positive spatial spillover effect.Therefore,it provides theoretical reference and reference for implementing high-quality collaborative innovation of G60 Science and Technology Innovation Corridor and promoting innovation integration strategy of Yangtze River Delta.
