京津冀地区创新政策对区域创新绩效影响的空间计量分析

提升区域创新绩效是在创新驱动发展背景下促进区域发展的重要手段.对京津冀43个区市2013—2018年的创新政策进行量化,构建空间计量模型,实证研究京津冀各区市创新政策对区域创新绩效的影响.研究结果表明:京津冀各区市创新政策与创新绩效均呈现显著正向空间相关性,空间聚集特征明显;创新政策的实施有利于提升本区域创新绩效,且对相邻区域创新绩效存在空间影响效应;创新政策对区域创新绩效的影响及空间效应均存在区域异质性.相对于天津和河北,北京市的创新政策实施对区内创新绩效的促进作用更明显;不同创新政策工具对创新绩效的影响存在差异,相比于需求侧政策和环境侧政策,供给侧政策对本地区创新绩效的促进作用最强;需求侧政策对相邻区域的创新绩效有正向影响,供给侧和环境侧政策对相邻区域创新绩效有负向影响.

The Impact of Innovation Policy on Regional Innovation Performance in Beijing-Tianjin-Hebei Region Based on the Spatial Measurement

Improving regional innovation performance is an important means to promote regional development under the background of innovation driven development. Based on the quantitative analysis of the innovation policy of the 43 districts and cities in Beijing-Tianjin-Hebei region from 2013 to 2018, a spatial econometric model was constructed to empirically study the impact of innovation policies on regional innovation performance. The research results show that: There is a significant positive spatial correlation between innovation policy and innovation performance in Beijing-Tianjin -Hebei.The implementation of innovation policies is conducive to improving the regional innovation performance, and there is a spatial effect on the innovation performance of adjacent regions. The impact of innovation policies on regional innovation performance and spatial effects are regional heterogeneity. Compared with Tianjin and Hebei, the implementation of innovation policies in Beijing has a more obvious role in promoting the innovation performance in the region. Supply side policy has the strongest effect on innovation performance in the region; Demand side policies have a positive impact on the innovation performance of adjacent regions, while supply side and environment side policies have a significant negative impact on the innovation performance of adjacent regions.
