以专利授权数来表征创新能力,采用变异系数、标准差及ESDA方法对1986-2012年中原经济区创新能力的时空差异演变进行了探讨,结果发现：(1)中原经济区创新能力绝对差异具有先慢后快不断拉大的趋势,而相对差异明显降低后一直在较低水平波动；(2)中原经济区年度Moran’s I变化不明显,而其五年段均值的Moran’s I上升趋势明显；(3)中原经济区创新能力空间结构特征基本呈沿着连霍高速中间强两端弱的格局,且创新能力强的地市主要位于交通网密集的中原城市群核心城市；(4)中原经济区创新能力空间集聚性在不断增强,主要表现为低低集聚类型的增多；(5)郑州和洛阳基本一直是高高集聚的类型；南阳发展为高低集聚类型；驻马店及淮北等经济欠发达地区大多数时期都是显著的低低集聚。

The study uses the number of the patents granted to characterize innovation capability, and investigates the spatial and temporal evolution the difference of innovation capability in Central Plains Economic Region by coefficient of variation, standard deviation and ESDA method between 1986 and 2013 Five conclusions are found as follows:(1)The absolute difference of innovation ability has the first slow after the fast widening trend in central China Economic Zone but relative difference decreased significantly after fluctuated in a relatively low level;(2) Annual Moran "s I did not change significantly in Central Plains Economic Area, While Moran "s I five-year period of mean increased;(3)The spatial structure of innovation ability is basically middle strong ends weak pattern along the Lianhuo Expressway, and innovation ability strong, mainly located in the traffic network intensive core city in Zhongyuan city group.(4) The space Cluster of innovation capability is growing, mainly for the increase of low concentration type;(5) Zhengzhou and Luoyang have been type high agglomeration,Nanyang has High and low concentration type, most of the economically underdeveloped areas is significantly low concentration,such as Zhumadian and Huaibei .
