摘　　要：创新作为城市和区域发展的主要动力,而区域层面的创新集群和活动一直是城市地理学研究的热点。本研究以中国长三角地区41个城市为研究案例,从创新阶层、创新经济投入、创新文化环境、创新产出四个维度的指标入手,通过创新引力和外向创新联系度,来观察长三角创新城市群落的组织特征和空间网络。结果表明:①城市创新引力。形成7级划分,第一级别城市为上海、苏州、杭州、南京、无锡,前4级城市的创新引力与后3级城市有明显的分野;②创新外向联系。空间上呈现沿沪宁线和沪杭线的"八字形"的核心结构和沿海"C型"的潜力圈层;③网络总体特征。创新群落由核心圈层、关联圈层和边缘网络三部分组成,上海、苏州、杭州、南京、无锡相关联形成两个嵌套三角形的结构组成了核心圈层。Many recent urban geographic studies focus on innovation as a main driving force of urban development and regional-based innovation and activities. Based on statistical data for 2012, this study examines 41 cities in the Yangtze River Delta Region （YRDR） in terms of 15 indicators for measuring creative class formation, investment in the creative economy, cultural creative environment and creative outputs. It explains the organizational features and spatial networks of creative cities in YRDR by looking into innovation gravity and external innova- tion linkages. The results show that： ① urban innovation gravity can be divided into seven categories with Shanghai, Suzhou, Hangzhou, Nanjing, and Wuxi situat- ed in the top category. A clear dividing line can be identified between the highest 4 categories and the lowest 3 categories. ② external innovation linkages are exhib- ited spatially along the axis of Shanghai-Nanjing and Shanghai-Hangzhou as well as ＂c＂ shaped coastal structure; ③ the general structure of the network includes the core circle, associated ring circle and the periphery circle with Shanghai, Su- zhou, Hangzhou, Nanjing and Wuxi forming two core and interlocking triangles.
