创新产出与国内外技术引进关系VAR实证研究——基于我国大中型工业企业数据

采用向量自回归方法,建立我国大中型工业企业创新产出与国内、国外技术引进之间关系的VAR实证模型,并进一步利用脉冲响应函数和方差分解探索影响系数大小和时期变化规律。研究表明:大中型工业企业创新产出对国内、国外技术引进的冲击反映十分敏感;各变量影响系数在短期和长期存在差异;单位根检验、格兰杰因果检验及协整检验发现他们间存在一种长期均衡稳定的关系。最后,总结并提出促进我国地区大中型工业企业创新产出之路的对策。

This paper used vector auto regression to establish VAR empirical model reflecting relationship between the introduction of foreign technologies and innovation output of large and medium - sized industrial enterprises in China, and further used impulse response function and variance decomposition to explore size of influencing coefficient and rule of time variation. The research has showed that the response to the impacts of innovation and output of large and medium - sized industrial enterprises on the introduction of domestic and foreign technology is extremely sensitive; the coefficient of each variable exist differences between the short term and long - term; by unit root test, Granger causality test, and co - integration test, it ahs been found that there is a long - term stable equilibrium relationship among the co - efficient of each variables. Finally, the paper snmmarized and proposed the countermeasures to promote the path of large and mediumindustrial enterprises innovation in China.
