对外开放度与经济增长的实证研究——基于河北省数据的协整分析

本文运用协整检验、误差修正模型和格兰杰检验对河北省对外开放程度与经济增长之间的关系进行了实证研究。结果表明,长期来看,河北省经济增长与对外开放度存在长期稳定的协整关系,短期内对外开放对河北省经济增长的影响较小。对外开放和实际GDP增长之间具有互相的因果关系,但对外开放对经济增长的影响大于经济增长对对外开放的影响。

An Empirical Study on Openness Degree and Economic Growth——in Terms of Hebei Province via Cointegration Analysis

The authors make empirical research on the relationship between openness degree and economic growth in Hebei Province by using Error Correction Model and Granger test of causality. The result shows that there is a eointegration between the two indexes in a long term, but openness degree makes little influence on economic growth in short run. Furthermore, there is a mutual causation between openness and actual GDP growth, but the former gives a greater influence on the latter than the latter to former.
