摘要
随着我国社会经济的快速、深入发展,交通运输对经济发展的作用越来越明显。科学地探讨这种关系,并运用这种关系去能动地指导我们的规划、计划和发展,具有十分重要的意义。本文通过主成分分析法和回归分析法,建立交通运输与经济发展的数学模型,揭示交通运输与经济发展之间相互制约、相互促进的内在密切联系。
With the rapid and deep development of social ecnomy,the influence of transportation to the economic development becomes more and more obviously. It is of great importance to scientifically explore their relation and avail the relation to instruct our planning and development. By using the analysis of main components and the regression analysis, a mathematical model between transportation and economic davelopment is built to bring to light the intrinsic close connection between them whose relations are restriction and promotion mutually.
