运用协整检验、Granger因果检验、VEC模型、脉冲响应函数及方差分解等计量方法，对政府投资、民间投资与GDP之间的关系进行全面考察。结果表明，政府投资与民间投资在促进经济增长的作用上存在差异：短期内，政府投资作用有限，民间投资对经济的拉动作用大于政府投资；长期看，政府投资对经济稳定增长的作用大于民间投资。因此，刺激短期经济增长，需要充分调动民间投资；而为了长期经济健康发展，需要政府长期有规划的投资。

This paper herein intends to fully investigate the relationship between government investments, private investments and GDP growth, through such measurement approaches as cointegration test, Granger causality test, VEC model, IRF （ Impulse Response Function） and variance decomposition. The results indicate government investments and private investments play a varied role in pushing economic growth ： from a short-term perspective, government investments play a limited role while private investments play a greater role in comparison; while from a long-term angle, government investments perform better than private investments in driving economic stability and growth.
