企业创新投资的空间互动关系研究

Research on the Spatial Effect of Enterprise Innovation Investment

在落实国家创新驱动发展战略过程中,企业是微观层面实施者,立足企业研究创新投资的空间互动关系,对于激发企业间创新投资联动效应,推动国家创新驱动发展战略实施具有积极意义。构建不同权重矩阵,运用空间计量模型研究发现:企业与企业之间的创新投资存在正向空间互动关系;企业之间的创新投资空间互动关系存在行业门槛,表现为跨行业衰减;创新投资的空间互动关系在多维邻近的企业间更容易达成。最后,提出建议:甄别高、低水平创新投资集聚区,基于不同创新投资水平“量体裁衣”助推企业创新投资;创新投资的空间互动可以在企业间形成涟漪式扩散,应在扩散过程中重视和充分发挥同行业企业作为关键传导节点的作用;选出一批合适的企业进行重点管理,以“点”带“面”促进更多企业创新投资行为。

Enterprises are micro implementers of the national innovation strategy.The research on the spatial effect among enterprises in innovation investment is of positive significance for stimulating the linkage effect of innovation investment and promoting the implementation of the national innovation strategy.By building different weight matrices and using spatial econometric model,this paper finds that there is a positive spatial interaction,the spatial effect of innovation investment is more significant among enterprises in the same industry than in different industries,and the higher the similarity between enterprises,the stronger the spatial effect of their innovation investment.Based on the these findings,we suggest that the management department should identify high and low level innovation investment cluster areas and promote the innovation investment of enterprises in a tailor-made manner.We should give full play to the role of enterprises in the same industry as a key transmission node in the spatial diffusion of enterprise innovation investment.In addition,we can select some appropriate enterprises and make them drive more similar enterprises'innovation investment.
