Abstract:

Taking Jiangsu county district as the research unit, this paper explored the spatial differentiation characteristics of R&D enterprises in Jiangsu province in 2005, 2011 and 2017 with the methods of standard deviation ellipse, Ripley's K function and exploratory spatial data analysis, and then investigated the influencing factors of spatial differentiation of R&D enterprises in Jiangsu province by the negative binomial regression model, the main conclusions are as follows. The R&D enterprises show a stable northwest-southeast spatial distribution pattern, and it has significant spatial clustering, and the scale and intensity of the clustering increase first and then decrease. What's more, the cold and hot spots of R&D enterprises are distributed in blocks, and there is an obvious phenomenon of "club convergence". In addition, R&D enterprises, development zones and institutions of higher learning have a high degree of spatial matching. Lastly, factors such as economic development level, labor cost, development zone construction, proximity to institutions of higher learning and agglomeration economy have a significant influence on the spatial distribution of R&D enterprises in Jiangsu Province.

Key words: R&D enterprises, Jiangsu Province, spatial agglomeration, spatial correlation, influencing factors

摘要:

以江苏省县区为研究单元,综合运用标准差椭圆、Ripley’s K函数和探索性空间数据分析方法,探究2005、2011和2017年江苏省研发企业的空间分异特征,并采用负二项回归模型考察江苏省研发企业空间分异的影响因素,研究结论如下:研发企业空间分布呈现出稳定的西北-东南分布格局,且具有显著的空间集聚性,聚集规模和强度先增强后减弱;研发企业冷热点呈块状分布,存在明显的“俱乐部趋同”现象;研发企业和开发区、高等学校空间匹配程度较高;经济发展水平、劳动力成本、开发区建设、邻近高等院校以及集聚经济等因素对江苏省研发企业空间布局影响显著。
