摘要
介绍了柯布-道格拉斯函数原理,在此基础上,利用内蒙古自治区的公路建设投资及其各影响因子构建了投资函数模型。对该模型进行多元线性回归发现,GDP增长对公路建设投资的贡献率很大;投资与贷款利率存在明显的正相关关系;股市市值对内蒙古公路建设的投资也具有一定的影响,从其规模来看,其影响并不是很小。同时,对内蒙古自治区公路建设投资提出了一些合理性的建议。
This article describes the principle of Cobb-Douglas function. Based on the project practice, and then establishes the model of investment function by using the investment in highway construction in Inner Mongolia, and influencing factors. It was found through the multi-linear regression analysis on the above model that the rate of contribution to the highway construction is very large for the growth of GDP; the distinct positive correlation between investment and the interest rate of loans; the market value of stocks is of certain influence to the highway construction in Inner Mongolia, with not small influence in view of its scale. Besides, this article puts forward to some reasonable suggestions for investment in highway construction in Inner Mongolia.
