摘要
以山东省17个地级市规模以上工业企业新产品产值作为创新产出的测量指标,对全省2002-2011年市域创新产出进行探索性空间数据(ESDA)分析。通过计算Moran’s I指数以及LISA表的分析发现:10年间,山东省各市创新产出值均有较大幅度的提高,但区域空间差距也非常明显,市域创新能力在空间上现出明显的不均衡特点;山东省创新产出能力集中程度不高,呈现出随机分布的态势,并保持相对稳定的变化趋势;Moran’s I值的贡献主要是来自跨象限的地区和高高产出地区集聚作用结果,创新产出核心区的空间知识溢出暂未显现。
Using the methods of exploratory spatial data analysis(ESDA), this paper analyzes the spatial distribution of innovation outputs, measured by the output of new product of large and medium-sized industrial enterprises,throughout 17 cities in Shandong province from 2002 to 2011 by computing the Moran's I and the LISA plot, we can conclude that: Nearly ten years, value of innovative output in cities has dramatically increased, but the gap between the regions is also very clear and outs are distributed differently;The trend that low concentration level of innovative outputs of Shandong Province is relatively stable; The value of Moran's I comes from the clustering of NOT-Clearly innovation and High-High innovation output region, and the core of innovation output on Spatial Knowledge Spillovers has not appeared.
