本文针对某省在发展公路运输业中,公路运输对于各个行业的建设和提高,直接为国民经济输入活力,对相关行业直接消费,设计公路运输中某些因素对于GDP的影响.
首先,我们参考了附件二所给出的公路建筑业投入产出表的数据,通过分析一系列的数据,我们建立投入产出平衡方程,算出公路每增加一个单位的需求,所对各个行业GDP的产出.
其次,通过附件一所给出的公路运输调查数据,我们运用相关性分析法,分析整个公路运输行业有多少主要因素增加GDP,然后提炼出主要因素,运用多元线性回归方法,分析当这些主要因素分别增加一个单位时,GDP将增加多少个单位.
针对问题二,我们将对现有数据进行优化,引入一些外部条件的调查数据,扩充调查容量,优化模型的精度,使其更加科学化.最后,对模型优缺点进行了系统评价与改 ,并给出一些可行性意见

In this paper the development of the highway transportation in China,road transport construction for various industries and improve the vitality of national economy,direct input,direct consumption of related industry,design of highway transportation in some factors affect GDP.First of all,we refer to the highway construction in annextwo of the input-output table data,through a series of analysis data,we establish the input-output balance equation,calculate the highway every increase of one unit of demand of various industries,GDP output.Secondly,through the highway transportation survey data is given in AnnexI,we use correlation analysis,analysis of the road transport industry has many main factors that increase the GDP,and then extracted the main factors,using multiple linear regression method,analysis of these factors were increased when a unit,GDP will increase the number of units.For question two,we will optimize the existing data,survey data into some external conditions,extended investigation capacity,optimization model,make it more scientific.Finally,the model advantages and disadvantages of the system evaluation and modification,and gives some feasible suggestions.
