本文运用协整分析方法和误差修正模型,并结合Granger因果检验对1952—2008年我国信息化水平与经济增长的关系进行了探讨。研究表明:我国信息化水平与经济增长之间存在长期稳定的均衡关系,信息化水平对经济增长有积极的促进作用,但短期内这种作用不够明显;信息化水平与经济增长存在显著的双向因果关系。
The paper tries to investigate the relationship between the infomationization level and the economic growth in China during the years between 1952 and 2008, which is based on and guided by the co-integration analysis and error correction model as well as Granger causality test. The results show that: there is a long-term stable equilibrium relationship existing between the two objects studied, and the former one takes a positive role to advance the latter one. However, this promotion seems to be not so significant in the short term; besides, the two-way causality could also be found between the two.
