摘　　要：以黄河流域91个地域单元的专利授权数据测度黄河流域城市创新能力,揭示2004—2019年黄河流域城市创新格局时空演变特征,并分析影响城市创新能力演变的相关因素。结果表明:黄河流域创新格局地带性差异显著,呈下游—中游—上游梯式递减态势。黄河流域城市创新能力空间相关性显著,高-高和低-低集聚现象明显,高-高集聚区集中分布在下游山东半岛,低-低集聚区主要分布在中上游省区,并且低值集聚区范围远大于高值集聚区。政府财政投入、人才要素、经济基础、信息化水平、金融环境、经济外向度6个指标共同影响着黄河流域城市创新格局的形成与演变。其中,信息化水平和政府财政投入影响较大,经济基础和人才要素次之,金融环境和经济外向度影响相对较小,所有因素影响均为正。This paper uses the patent authorization data of 91 cities in the Yellow River basin as the indicators for measuring urban innovation capability to reveal the temporal-spatial evolution characteristics of innovation in the Yellow River Basin during 2004-2019.Then the spatial econometric model has been constructed to analyze influencing factors.The results are as follows:Firstly,there is a very obvious economic zonality of the innovation pattern in the Yellow River Basin which presents a ladder decreasing trend distribution from downstream to midstream,and to upstream.The spatial distribution pattern is relatively stable.Secondly,the spatial correlation of urban innovation capability is significantly positive in the Yellow River Basin,which indicates that the similar areas of urban innovation capability are high or low concentration.Among them,the high value agglomeration area is located in Shandong Peninsula in the downstream of the Yellow River and the low value agglomeration area is mainly distributed in the provinces in the midstream and upstream of the Yellow River,and the range of low value agglomeration area is much larger than that of high value agglomeration area.Thirdly the six factors of government financial investment,talent elements,economic foundation,information level,financial environment and economic extroversion affect the formation and evolution of the spatial pattern of urban innovation capability jointly in the Yellow River Basin.Especially,information level and government financial investment are the most important factors,followed by economic foundation and talent elements.Financial environment and economic extroversion have little impact on urban innovation capability.
