摘　　要：以长江经济带110个地级市作为研究对象,构建二进制空间权重矩阵和反距离空间权重矩阵,对长江经济带区域创新分布规律进行了全局和局部空间自相关检验,选取2011—2022年面板数据构建空间计量模型,研究了长江经济带交通一体化建设对沿江城市创新绩效的空间效应。实证结果表明,长江经济带区域创新空间格局分布具有空间自相关性,表现出“同质集聚、异质分离”的特征。长江经济带交通基础设施完善对创新产出具有显著影响,进一步验证发现交通条件改善主要通过要素流动和极化效应等机理显著提高中心城市的创新绩效,但是在一些地区中心城市与周边城市的区域创新差距会扩大。Taking 110 prefecture level cities in the Yangtze River Economic Belt as research objects,binary spatial weight matrix and inverse distance spatial weight matrix were constructed to test global and local spatial autocorrelation of regional innovation distribution in the Yangtze River Economic Belt.Panel data from 2011 to 2022 were selected to construct a spatial econometric model to study the spatial effects of integrated transportation con‐struction in the Yangtze River Economic Belt on the innovation performance of cities along the Yangtze River.The empirical results indicate that there is spatial autocorrelation in the spatial pattern distribution of innovation in the Yangtze River Economic Belt region that features"homogeneous agglomeration and heterogeneous separation".The improvement of transportation infrastructure in the Yangtze River Economic Belt has a significant impact on innovation outputs.Further verification shows that the improvement of transportation conditions mainly improves the innovation performance of central cities through mechanisms such as factor flow and polarization effects,but in some areas,the regional innovation gap between central cities and surrounding cities will be wider.
