基于ESDA-GWR的安徽省创新产出的空间分布及影响因素分析

The Spatial Distribution of Innovation Output and Its Influencing Factors Based on Anhui Province

摘要:

以安徽省16个地级市为研究单元,通过空间自相关分析,发现地级市创新产出间存在正向的空间相关性,并将这16个地级市划分为不同类型区域。在此基础上,运用地理加权模型,兼与OLS模型进行比较,探索了不同创新要素对安徽省创新产出的影响及其空间差异性。研究结果表明：R D人员占比与创新产出呈正相关关系,且影响最为显著,而R D经费支出占比、工业企业R D项目数占比和每万元GDP中地方政府对创新活动资金投入对创新产出的影响有正有负。

Abstract:

With the help of exploratory spatial data analysis methods, we analyzed the phenomenon of innovation elements agglomeration in Anhui, found that there is a positive correlation between the level of innovation and output. Through the Moran scatter plots and local indicators LISA cluster table, Anhui can be divided into different types: HH region, LL region and LH region. On the basis of comparison with the ordinary least square(OLS), we used the empirical analysis method of geographic weighted regression(GWR) to study the effect of different innovation elements on regional innovation output. The results show that R D personnel ratio significantly and positively related to innovation output, while the impact of R D expenditure ratio, industrial enterprises R D project ratio and capital investment of local government in every 10, 000 yuan of GDP to innovation activity have both positive and negative.
