黄河流域创新产出的空间溢出效应

Spatial Spillover Effects of Innovation Output in the Yellow River Basin

为提高黄河流域城市间的创新能力,以专利申请量作为黄河流域创新产出指标,运用空间杜宾模型,对黄河流域创新的空间溢出效应进行测度及分解,通过实证分析得出黄河流域创新产出的空间溢出效应。结论表明:科研投入和经济发展对黄河流域创新产出的总效应为正,整体上促进了黄河流域的创新水平;外商投资的总效应为负数,说明外商投资从一定程度上抑制了黄河流域的创新产出。

In order to improve the innovation capacity for the cities along the Yellow River basin,the spatial spillover effect of innovation output in the Yellow River basin was measured and decomposed by using spatial Durbin model and taking the number of patent applications as the innovation output index.The spatial spillover effect of innovation output in the Yellow River basin gets obtained through empirical analysis,and the results go as the following:the total effect of scientific research input and economic development on innovation output is positive,which promotes the innovation level of the Yellow River Basin as a whole;the total effect of foreign investment is negative,which indicates that foreign investment restrains innovation output in the Yellow River basin to some extent.
