文章评估了浙江省各县域科技创新活动的发展水平，分析了其空间聚集效应。在建立科技创新活动多指标综合评价体系的基础上，通过主成分分析法评价了浙江省90个县域2009~2012年的科技创新活动发展水平，并通过Moran’s I指数进一步分析了浙江全省以及各区县间的科技创新活动的空间聚集效应。结果表明：浙江省科技创新活动发展存在较明显的“东北崛起，西南塌陷”的空间格局，浙东北地区为科技创新活动发达聚集区，而浙西南为滞后聚集区。在时序上，区域创新活动水平总体呈稳定状态。创新活动发达区与滞后区的主要差距在于创新组织上。结论对于促进县域空间尺度的科技创新研究和实践具有一定的指导意义。

The paper focus on the development evaluation of the scientific and technological innovation (STI) in counties of Zhejiang Province and its regional concentration. A evaluation system with multiple indicators was established. Using the indicators and Principal Component Analysis method, the study evaluated the development level of STI for 90 counties in Zhejiang Province from 2009 to 2012. Furthermore, the regional concentration of STI in Zhejiang, and among its counties were assessed by the Moran’s Index analysis. The result showed: (1) the development of STI in Zhejiang has a clear pattern which can be described as “The Northeast Rises, and The Southwest Falls”. In other words, the northeastern region of Zhejiang is the highly-developed zone of STI, while the southwestern is less-developed; (2) the general level of STI is stable and constant during the four years (3) the major difference between the developed and the less-developed region is the innovative organization. The results has some implications for the development of innovation at county scale.
