摘要
文章通过对广西近年建设的高速公路投资及相关数据的整理,分析筛选了包括桥隧比、路基宽度、互通个数等影响高速公路投资的主要控制因素,并考虑建筑业物价上涨影响,将选定的控制因素作为自变量,建立了广西高速公路投资回归模型,为高速公路工程的投资决策、造价管理提供依据。
Through Guangxi expressway investment construction and related data collation in recent years,this article analyzed and selected the main controlling factors affecting the expressway invest-ment including the bridge and tunnel ratio,roadbed width,and the number of interchange,and consid-ering the impact of construction industry price increases,with the selected control factors as independ-ent variables,it established Guangxi expressway investment regression model,thereby providing the basis for investment decisions and cost management of expressway engineering.
