【摘要】 协同创新作为新发展阶段下的重要创新模式，能够加强地区间的互动与交流，缩小发展差距，实现区域协调发展。基于长三角地区地级市两两组合构成的城市对，选取2000-2023年的相关数据，实证检验协同创新影响发展差距的方向与路径。研究结果表明，城市间协同创新能够显著缩小发展差距，并且这种影响在城市对空间相邻、地理距离、文化距离和行政边界的作用下存在显著的异质性；协同创新主要通过促进产业分工、推动资本流动和加强经济联系三个途径缩小区域发展差距。更多还原

【Abstract】 Collaborative innovation, as an important innovation model in the new development stage, enhances interaction and communication between regions, reduces the innovation gap, and achieves regional coordinated development. Based on city pairs formed by the cities at the prefecture level in the Yangtze River Delta, this paper empirically tests the direction and pathways through which collaborative innovation affects coordinated development, using relevant data from 2000 to 2023. The results show that collaborative innovation has a significant positive impact on coordinated development, and this impact exhibits notable heterogeneity under the influence of factors such as spatial adjacency between cities, geographical distance, cultural distance, and administrative boundaries. Collaborative innovation primarily promotes coordinated development through three channels: promoting industrial specialization, facilitating capital flow, and strengthening economic linkages.更多还原
