从实证角度,运用相关性分析、ADF检验、协整检验、广义脉冲响应分析、方差分解和Granger因果检验等计量经济学方法,对制造业企业信息化水平与工艺创新能力之间的互动关系进行了研究,并得出如下结论:制造业企业信息化水平与工艺创新能力之间存在一种长期稳定的协整关系,具有协调变化的趋势,而且二者相互影响,存在双向的Granger因果关系。
From the empirical point of view, this paper studies the relationship between informatization level and process innovation capability in manufacturing enterprise by using econometric methods such as correlation analysis, augmented dickey fuller (ADF) test, cointegration test, generalized impulse response analysis, variance decomposition and granger causality test. The conclusion is that it is a long-term and stable cointegration relationship between informatization level and process innovation capability in manufacturing enterprise, and they tend to change in concert and affect each other, with a two-way granger causality between them.
