社会资本作为无形资本的重要组成,是提高区域创新能力的有力保证。基于2009-2014年长江经济带九省二市的面板数据,利用空间杜宾模型分析社会资本对区域创新能力的非线性关系。结果表明：(1)长江经济带区域创新能力存在显著的空间正相关性,但整个空间呈现不均衡的阶梯状分布格局；(2)社会资本与区域创新能力之间并非完全线性相关,结构社会资本对区域创新能力的影响不显著,而认知社会资本对区域创新能力具有显著正效应；(3)R D人力投入、R D资金投入和教育环境对区域创新能力均呈现显著正效应,其中教育环境对区域创新能力的作用最突出。

Social capital as an important part of incorporeal capital, is a strong guarantee of improving regional innovation capability. Based on the panel data of 11 provinces of Yangtze River Economic Belt from 2009 to 2014, using Spatial Durbin Model, this article analyses the non-linear relationship between social capital and regional innovation capability. The results show as follows: (1) Regional innovation capability in Yangtze River Economic Belt shows a positive spatial correlation, but whole space largely shows the unbalanced ladder-like distribution pattern; (2) The relationship between social capital and regional innovation capability is not completely linear correlation. Structural social capital has no remarkable effect on regional innovation capability, but cognitive social capital brings significant positive effects on regional innovation capability; (3) R D personnel, R D expenditure and educational environment bring significant positive effects on regional innovation capability, among them, effect of educational environment on regional innovation capability is the most prominent.
