摘　要：

 科技创新的空间溢出对长江经济带加快增长方式转变，促进产业结构调整，探索东中西部互动合作，提升经济带整体经济发展效率具有重要价值。引入空间关系特征和社会经济特征两类空间矩阵，运用静态与动态空间面板计量模型进行量化分析可以发现：空间关系特征和社会经济特征均对创新产出的空间溢出有显著的正效应，但社会经济特征影响更大，信息传播距离在长期中比经济距离对创新活动的空间影响更显著。选择变量也存在空间溢出效应差别：FDI 在短期和长期均会产生科技创新空间溢出负效应，R&D 人员的短期空间溢出效应显著为正，而长期空间溢出效应不显著，外在环境对区域科技创新的空间溢出有显著的正效应。

Abstract    The spatial spillover of technological innovation is of great value for the Yangtze

River Economic Belt (YREB) to accelerate the change of growth mode, promote the adjustment of industrial structure, explore the interactive cooperation between the East and the West and to enhance the economic development efficiency. By using static and dynamic space panel econometric models, this paper introduces spatial relationship characteristics and social-economic characteristics of two kinds of spatial matrices compares and analyses the spatial spillover effect of technological innovation output in 11 provinces and cities of the YREB in year 2000 to 2013, and discusses the overflow path and coordination strategy among the provinces. It has been found that the spatial relationship and social- economic characteristics have significant positive effects on the spatial spillover of innovation output, but the social-economic characteristics have a greater impact. In contrast, information transmission distance has more significant impact on innovation activities than economic distance in the long term. There is also a difference in the spatial spillover effect of selection variables: the spatial spillover effect of FDI is negative both in short and long term. Spatial spillover effect of R&D personnel is positive in the short term, but not in the long term. External environment has a significant positive effect on the spatial spillover of regional technological innovation. Based on our findings, the paper proposes some policy suggestions on spatial synergy of regional technological innovation. Finally, policy suggestions are put forward on how to promote the spatial synergy of regional technological innovation. The first and foremost is to reach consensus on issues and to carry out network coordination. Then we should work together to advance institutional reform and choose policy tools appropriately and implement policy integration. Meanwhile we should optimize the network channels of collaborative innovation and build a unified technology market system.

Key words   Yangtze River Economic Belt; technological innovation; spatial spillover effects; regional synergy; spatial weight; spatial weight based on economics distance; spatial weight based on information distance; FDI
