基于我国30个省域的区域创新时空变化分析

On Spatiotemporal Change Analysis for Regional Innovation based on 30 Provinces in China

本文以我国30个省域作为空间研究对象,用专利申请受理数作为创新产出的衡量指标,对我国1998-2015年期间省域创新产出的空间分布进行探索性空间数据分析。通过运用热点分析,可以看出我国创新活动呈现集聚现象,主要表现在少数沿海城市创新能力强且不断自我强化;通过运用全局的Moran’s I指数进行分析,得出我国少数省域之间的创新活动存在着显著的空间自相关,说明知识溢出具有空间局限性。研究结果显示,我国省域创新活动的地域性特征十分显著。因此,建议加强相邻地区的经济合作与文化交流,加强相互协同,降低地区间经济交流的成本,进而提升省域间的创新活动能力。

Exploratory spatial data analysis on space distribution for provincial innovation output from 1998 to 2015 in China is based on the objects of space research covering 30 provinces in China and takes the number of pattern application cases as the measure index for innovation output.The paper,through hotspots analysis,finds out agglomeration phenomenon on innovation activities,which is proved by a few coastal cities'strong innovation and self-strengthening ability.The overall Moran's I index verifies that there is a spatial autocorrelation on innovation activities among certain provinces,which means the spatial limitation on knowledge spillover.Findings have shown that there are significant regional characteristics on innovation activities.Therefore,promoting the activity depends on strengthening the economic cooperation and cultural exchange among neighboring regions,pushing mutual synergy and reducing the cost of economic exchange.
