【摘要】 创新产出是体现区域创新能力的最重要指标,以京津冀13个地级及以上城市为例,考察了京津冀创新产出的空间分布格局,并基于拓展的知识生产函数和空间计量模型,实证分析了创新经费投入、创新人员数量、地区经济发展水平和信息化水平4个因素对京津冀创新产出空间分布的影响。研究结果表明:京津冀创新产出的空间分布呈向京津两市极化的特征,并存在空间负自相关性。从京津冀创新产出的影响因素来看,政府创新经费投入和地区经济发展水平对本地区创新产出有显著促进作用,但溢出效应不显著;创新人员数量对本地区及邻近地区创新产出的影响均显著为负;信息化水平对本地区创新产出的影响不显著,但对邻近地区存在显著的正向溢出作用,据此提出了提升京津冀协同创新能力的对策建议。更多还原

【Abstract】 Innovation is an important force to promote the sustainable development of regional economy.Taking 13 cities of Beijing-Tianjin-Hebei region as an example,this paper investigates the spatial distribution pattern of innovation output in Beijing-Tianjin-Hebei region;and based on the extended knowledge production function and spatial econometric model,this paper empirically analyzed the impact of four factors,namely,the input of innovation funds and the number of innovators,as well as the level of regional economic development and information technology,on the spatial distribution of innovation output in Beijing,Tianjin and Hebei.The results show that there is a negative spatial correlation between the regional innovation outputs of Beijing-Tianjin-Hebei region,and there is an isolated polarization effect around Beijing and Tianjin.Regional economic development and the input of government funds have a significant effect on innovation output,but the spillover effect is not significant.The impact of human capital on innovation output is significantly negative.The impact of information level on innovation output in this region is not significant,but has a significant positive spillover effect on the adjacent areas.Finally,based on the above conclusions,the paper puts forward countermeasures and suggestions for the collaborative innovation of Beijing-Tianjin-Hebei region.更多还原
