文章对我国建设投资和国民经济之间的关系进行了定量的分析 ,建立了能反映二者之间长期均衡和短期波动关系的误差修正模型 ,从而得到近阶段国民经济增长对我国建设投资的弹性系数 ,反映了建设投资对国民经济增长的贡献水平。从模型分析的结果显示 ,无论是固定资产投资 ,还是建筑安装投资 ,GDP对它们的弹性系数都大大超过它们各自在 GDP中所占的比重。这表明建设投资能够高效率地拉动国民经济的增长 ,是刺激经济活动的重要手段之一。
The article makes a quantitative analysis of the relationship between construction investment and national economy in our country and establishes an error correction model that can reflect the long-term equilibrium and short-term fluctuations between the two, so as to obtain the elasticity of national economic growth to China’s construction investment in the recent stage The coefficient reflects the contribution of construction investment to the growth of the national economy. The results of the model analysis show that the elasticity coefficient of GDP to both of them is much higher than their respective share in GDP, whether it is investment in fixed assets or investment in construction and installation. This shows that construction investment can effectively boost the growth of the national economy is one of the important means to stimulate economic activity.
