文章采用突变级数法构建航空航天业创新能力的指标体系与评价模型,运用2000~2014年航空、航天器及设备制造业专利数据,结合聚类分析方法,对我国航空航天业创新能力的动态演进与空间格局进行分析。结果表明:航空航天业创新能力在2000~2014年间经历三个阶段跃迁:较低水平阶段(2000~2007年)、中等水平阶段(2008~2011年)、较高水平阶段(2012~2014年),两次突变时点分别对应2008年与2012年;当前航空航天业创新能力在空间格局上呈现出显著的马太效应以及阶梯状分布特征,该特征与产业资源禀赋因素密切相关。
In this paper, the index system and evaluation model of the innovation capability of the aerospace industry are constructed by using the method of mutation series. Using the patent data of aerospace, spacecraft and equipment manufacturing industries from 2000 to 2014, combined with clustering analysis, this paper analyzes the dynamics of innovation capability of China’s aerospace industry Evolution and spatial pattern analysis. The results show that the innovation capability of the aerospace industry goes through three stages of transition from 2000 to 2014: the low level stage (2000 ~ 2007), the middle level stage (2008 ~ 2011) and the higher level stage (2012 ~ 2014) , Respectively, which correspond to 2008 and 2012, respectively. At present, the innovation capability of the aerospace industry shows a significant Matthew effect and a stair-like distribution pattern in spatial distribution. This feature is closely related to industrial resource endowments.
