本文依据2001～2011年我国经济发展指标GDP和制造业投资的相关数据,运用协整理论和格兰杰因果检验相关知识,对经济发展指标GDP和制造业投资的关系进行检验。结果表明,2001～2011年,经济发展指标GDP和制造业投资之间存在长期稳定的均衡关系。Granger Sims因果检验表明,短期内,经济发展指标GDP对制造业投资的影响并不显著,但中期来看,经济发展指标GDP对制造业投资的影响却是显著的,并提出相关建议。
Based on the data of China’s economic development indicators GDP and manufacturing investment from 2001 to 2011, this paper tests the relationship between economic development index GDP and manufacturing investment by using cointegration theory and Granger causality test. The results show that from 2001 to 2011, there is a long-term and stable equilibrium relationship between economic development indicator GDP and manufacturing investment. Granger Sims causality test shows that in the short term, the impact of economic development indicator GDP on manufacturing investment is not significant, but in the medium term, the impact of economic development indicator GDP on manufacturing investment is significant, and relevant suggestions are put forward.
