摘要
以1952年～2009年度数据为样本,基于误差修正模型检验了公路交通投资与经济增长的动态关系。结果显示公路交通投资对经济增长主要表现为短期行为且作用显著。公路交通投资每增长1%,GDP增长0.206%,三次产业增加值分别增长0.028%、0.338%和0.190%。
Based on the yearly sample data from 1952～2009, the relationship between highway invest- ment and economic growth is tested by cointegration-error correction model. The result shows that high- way investment can affect economic growth in the short run and such influence is significant. With every increasment of 1% from highway investment,GDP will increase 0. 206 % correspondingly. And the increas- ment of three industryies is 0. 028%,0. 338% and 0. 190%.
