以广东省21个地级市作为空间研究单元,以大中型工业企业新产品产值作为创新产出的测量指标,对全省2003—2010年市域创新产出进行探索性空间数据分析。通过计算基尼系数、Moran’s I指数以及Moran散点图的分析发现:①近7年间,广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;②广东省创新产出能力的集中程度不高并保持相对稳定的变化趋势;③广东省Moran’s I值的贡献主要来自于低创新产出地区的集聚,且目前暂未有高极化程度的高创新产出集聚区,说明创新产出核心区的空间知识溢出暂未显现。
In this paper, 21 prefecture-level cities in Guangdong Province were selected as spatial research units, and the output value of new products of large and medium-sized industrial enterprises was taken as the measurement index of innovative output to explore the spatial data of the innovation output of the city in 2003-2010. Through the analysis of Gini coefficient, Moran’s I index and Moran scatter plot, it is found that: ① In the past seven years, the output value of innovation in all cities in Guangdong Province increased greatly, but the regional spatial disparity was also obvious. ② The innovation production in Guangdong Province The concentration of capacity is not high and maintain a relatively stable trend of change; ③ The contribution of Moran’s I in Guangdong mainly comes from the agglomeration of low-innovation output areas, and there is currently no high-output agglomeration area with high polarization , Indicating that the spillover of spatial knowledge in the core area of innovation output has not appeared yet.
