为探究北部湾经济区6个城市的协同创新,首先,以空间效应为重点对协同创新进行分析,将时间维度纳入空间计量模型,并运用空间滞后模型和空间误差模型评估各因素对创新产出的影响,得出创新生产活动存在显著的正向空间相关效应.最后,通过Moran′s I和Moran散点图,对北部湾经济区六市的创新产出的全局空间相关性、局部相关性及其变化进行了验证,得出六市的创新产出呈空间负相关.
In order to explore the co-innovation of six cities in the Beibu Gulf Economic Zone, firstly, the paper analyzes the synergetic innovation by focusing on the spatial effect, including the time dimension into the spatial econometric model and the space lag model and the spatial error model to evaluate the impact of various factors on the innovation output We can draw a conclusion that there is a significant positive spatial correlation effect in the innovation production activities.Finally, through the Moran’s I and Moran scatter plots, the global spatial correlation and the local correlation of the innovation output of the Beibu Gulf Economic Zone And its changes were verified, and concluded that the innovation output of the six cities was negatively correlated in space.
