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