摘　　要：运用制造业发明专利授权数表征制造业创新能力,采用探索性空间数据分析、地理集中度指数和面板数据回归分析法,分别从省、市和县(区)的尺度解析长三角地区制造业创新能力时空演化特征,尝试探究制造业创新能力空间差异的影响因素及其作用强度。结果显示:①长三角地区制造业创新能力空间均衡性水平提高,各地创新能力差距缩小,空间集聚程度下降。②制造业创新能力高值区和高增长区呈现出等级分布和中心城市邻近分布,热点区由“单核心”逐步演化为“多核心”。③在制造业创新能力提升中,收入水平发挥突出作用;科技人才规模、金融业发展水平、经济基础、信息化水平作用显著,他们对不同行业作用的影响存在差异。Using the number of authorized invention patents in the manufacturing industry to characterize its innovation capability,this study employs exploratory spatial data analysis,modified Herfindahl-Hirschman Index and panel data regression analysis to examine the spatiotemporal evolution characteristics of manufacturing innovation capability in the Yangtze River Delta region from the scales of provinces,cities,and counties(districts).It also explores the influencing factors and their effect intensities of the spatial disparities in manufacturing innovation capability.The results indicate that:①The spatial equilibrium level of manufacturing innovation capability in the Yangtze River Delta region has improved,with reduced regional disparities in innovation capabilities and decreased spatial agglomeration degree.②High-value and high-growth areas of manufacturing innovation capability exhibit a hierarchical distribution and proximity to central cities,and the hot spot area gradually evolves from“single-core”to“multi-core”.③Income levels play a prominent role in enhancing manufacturing innovation capability,while the scale of scientific and technological talent,the development level of the financial industry,the economic foundation and the informatization level also have significant effects,with varying impacts across different industries.
