信息化水平与技术创新能力的协整关系——基于2005—2010年中国工业行业面板数据的实证分析

Cointegration Relationship between Informatization Level and Technology Innovation : Empirical Analysis on Based on China's Industrial Panel Data from 2005to 2010

利用2005—2010年中国工业37个细分行业的面板数据,运用面板单位根检验、面板协整检验、面板协整估计等方法检验了信息化水平、市场化水平、行业利润等因素对中国工业技术创新能力的影响。利用多种协整检验方法所得的结果一致表明,信息化水平、市场化水平、行业利润等与中国工业技术创新能力之间存在长期稳定的均衡关系;面板协整估计结果表明,信息化水平显著促进了中国工业技术创新能力的提升,但该影响具有明显的时序差异。

Using the panel data of China’s 37segment industries from 2005to 2010,this paper empirically analyzes the influence of informatization level,marketization level and industry profit on technology innovation capability of China’s industry through using such the methods as panel cointegration test,panel cointegration estimation,etc.The results based on multiple cointegration test all show that there exists the stable longterm equilibrium relationship between technology innovation capability of industry and informatization level,marketization level and industry profit.The result based on the panel cointegration estimation shows that informatization level promotes remarkably China’s industrial technology innovation capability,but this impact takes on the significant timing difference.
