摘要
通过分析交通设施建设与经济发展之间的关系,给出了它们之间的相关系数,同时把交通设施投资作为推动GDP增长的变量,建立了误差修正模型,并得到了反映它们之间长期均衡与短期波动的表达式.从推动力系数来看,无论是从全国的交通设施投资,还是从东部、中部及西部地区的交通设施投资来说,它们对国民经济增长的推动作用都是很明显的.因此,得到了交通设施建设对我国经济发展建设具有重大作用的结论.
The concept of correlation coefficient is induced and defined by analysing the relationship between transportation infrastructural construction and economic development. The the model of GDP long-term equilibria and short-term fluctuation with transportation infrastructure investment as variable have been built. With the view of impulse coefficient, transportation infrastructure investment promotes national economic growth in China.
