摘　　要：基于2006—2019年长江经济带106个地级及以上城市的面板数据,实证分析城市经济专业化、多样化对区域协同创新的影响效应,并按照不同地理区位、不同城市规模以及不同经济发展水平检验专业化和多样化影响效应的异质性特征。研究结果表明:城市经济专业化和城市经济多样化均能显著促进区域协同创新水平的提升,且城市经济多样化发挥的作用更加明显,同时城市经济专业化、多样化均具有显著的空间溢出效应。异质性分析表明:沿海城市、特大和大城市以及经济发达城市的区域协同创新更多地受益于城市经济多样化,而内陆城市、中小城市以及经济欠发达的城市则更适宜城市经济专业化发展。进一步研究发现:市场潜力的提升和人力资本水平的提高均能强化城市经济专业化、多样化对区域协同创新的正向影响,且城市经济专业化、多样化对区域协同创新的影响存在非线性特征,专业化呈现先增后减的发展趋势,而多样化的作用不断增强。Based on the panel data of 106 cities in the Yangtze River Economic Belt(YREB)from 2006 to 2019,this study empirically analyzes the impact of specialized agglomeration and diversified agglomeration on regional collaborative innovation.The results indicate that both specialized agglomeration and diversified agglomeration can significantly promote the level of regional collaborative innovation,and the role played by diversified agglomeration is more obvious.Meanwhile,both specialized agglomeration and diversified agglomeration have significant spatial spillover effects.Heterogeneity analysis finds that regional collaborative innovation in coastal cities,mega and large cities,and developed cities benefit more from diversified agglomeration,while inland cities,small and medium-sized cities,and less developed cities are more suitable for specialized agglomeration.Further research finds that the positive impact of specialized agglomeration and diversified agglomeration on regional collaborative innovation is strengthened by the increase of market potential and the level of human capital,and that the impact of specialized agglomeration and diversified agglomeration on regional collaborative innovation has a non-linear character,with specialized agglomeration showing a trend of increasing and then decreasing,while the diversified agglomeration is increasing.
