航空航天器制造业创新投入与产出关系研究

A research on the relationship between innovation input and output of aircrafts and spacecrafts manufacturers

结合典型相关分析和格兰杰因果关系检验两种方法,采用1995年至2013年我国航空航天器制造业相关数据进行实证研究,研究航空航天器制造业创新投入与产出关系。研究结果表明,我国航空航天器制造业的创新投入与产出之间虽然具有高度相关性,但并不存在明显的格兰杰因果关系。说明我国航空航天器制造业创新投入与产出之间还未形成良性互动关系。研究结论可以为管理实践提供理论参考。

Combined with the correlation analysis and granger causality test,the paper studies the relationship between innovation input and output of aircrafts and spacecrafts manufacturers with the data from 1995 to 2013 in China.The results show that although there is a high correlation between innovation input and output,the granger causality between them is not clear,which illustrates that positive interactive relationship between them has not been formed.The results can provide a theoretical reference for management practice.
