【摘要】：采用人工神经网络和普通最小二乘回归结合的方法,从全国层面以及东、中、西三大地区层面对地理邻近和认知邻近在合成型和解析型知识基础产业创新中的作用进行实证检验,得出地理邻近对合成型知识基础产业创新呈正效应显著的半倒"U"型影响,作用强度高于认知邻近的弱正向效应;地理邻近对解析型知识基础产业创新呈狭窄倒"U"型影响,作用强度低于认知邻近的平缓倒"U"型影响;东部地区两种知识基础产业创新中地理邻近初现饱和甚至抑制效应;中部地区合成型知识基础产业创新中地理和认知邻近正效应突出,解析型知识基础产业创新中地理和认知邻近效应为显著倒"U"型;西部地区两种知识基础产业认知邻近极其缺乏,对创新的影响不显著。
[Abstract]:Using the method of combining artificial neural network and ordinary least square regression, from the national level to the east and middle, The role of geographical proximity and cognitive proximity in the innovation of synthetic and analytic knowledge based industries is empirically tested at the three regional levels in the west, and the positive effect of geographical proximity on the innovation of synthetic knowledge based industries is found to be a significant semi-inverted "U" type. The intensity of action is higher than the weak positive effect of cognitive proximity, the influence of geographical proximity on the innovation of analytic knowledge base industry is narrow "U" type, and the effect intensity is lower than that of cognitive neighbor "U" effect. In the two kinds of knowledge base industry innovation in the eastern region, geographical proximity is saturated or even inhibited, and the positive effect of geographical and cognitive proximity is prominent in the synthetic knowledge base industry innovation in the central region. The geographical and cognitive proximity effects of analytic knowledge based industry innovation are significantly inverted "U" type, and the two knowledge based industries in the western region are extremely lacking in cognitive proximity, but the impact on innovation is not significant.
