考虑吸收能力的区域创新多维溢出效应

合理利用区域创新的空间溢出效应和价值链溢出效应，有助于区域创新发展与创新效率提升，而对区域创新溢出效应的利用程度则受其吸收能力影响。将创新过程分为知识创新阶段和产品创新阶段，利用Network Slacks-based Measure模型计算全国内地30个省域两阶段创新效率，将吸收能力引入空间溢出效应和价值链溢出效应对创新效率影响的研究中，并构建空间计量模型，检验吸收能力对知识创新效率和产品创新效率的影响。结果发现，空间溢出效应在部分年份显著，省域间没有形成稳定的空间关联关系；空间溢出效应显著时，提升吸收能力对知识创新效率和产品创新效率均有促进作用；价值链溢出效应不显著或者存在负向影响，创新过程两阶段相对独立，此时提高吸收能力对知识创新效率和产品创新效率提高没有显著作用，甚至具有负向影响。

Multidimensional Spillover Effect of Regional Innovation Considering Absorptive Capacity

The rational use of spatial spillover effect and value chain spillover effect of regional innovation is helpful for the development of regional innovation and the improvement of innovation efficiency.The extent to which spatial spillover and value chain spillover are utilized in a region is affected by its absorptive capacity.This article divides the innovation process into the knowledge innovation stage and the product innovation stage.The Network Slacks-based Measure model is used to calculate the two stages innovation efficiencies of 30 provinces in China.The absorptive capacity is introduced into the study of the influences of spatial spillover effect and value chain spillover effect to innovation efficiency to build a spatial econometric model.The impact of absorptive capacity on knowledge innovation efficiency and product innovation efficiency is tested.The results show that,the spatial spillover effect significantly existed in some years.There is no stable spatial relationship between provinces.When the space spillover effect is significant,increasing absorptive capacity can improve knowledge innovation efficiency and product innovation efficiency. The value chain spillover effect is not significant or negative. The two stages of the innovation process are independent. In this moment,increasing absorptive capacity has no significant effect on the improvement of knowledge innovation efficiency and product innovation efficiency,and even has a negative impact.
