本文采用2009-2015年长江经济带数据，通过构建区域创新能力评价指标体系，从创新要素区域间流动的视角构建了空间权重矩阵，借助引力模型测度了长江经济带各省市的空间关联强度，采用空间计量分析的方法研究了空间关联对区域创新能力的影响。实证结果显示，空间关联对区域创新能力具有正的显著影响，其主要通过两种方式实现，其一，有效增加R&D人员的交流频次，带来技术的空间外溢从而提高区域整体的创新水平；其次是降低创新资源的交流成本,提高R&D资本利用效率从而提高区域创新能力。

Based on the data of the Yangtze River Economic Belt in 2009 - 2015, this paper constructs the regional innovation capacity evaluation index system and constructs the spatial weight matrix from the perspective of the flow of innovation elements and measures the spatial correlation intensity of the Yangtze River economic belt by means of the gravitational model, The influence of spatial association on regional innovation ability is studied by means of spatial econometric analysis. The empirical results show that the spatial correlation has a positive effect on the regional innovation ability, which is mainly realized in two ways. First, it effectively increases the frequency of communication between R D personnel and brings the space spillover of the technology to improve the overall innovation level. Is to reduce the exchange of innovative resources costs, improve R D capital utilization efficiency to achieve regional innovation capacity impact.
