摘要:
调整材料价格是铁路建设管理过程中合理控制投资的重要方法，受地形、地质、当地经济、加工运输等多种因素影响，现行全国统一的价格调整机制无法真实反映现场实际情况。本文采用变异系数统计法，以四川、云南、贵州等西南山区省份的水泥、钢材、燃油料等主要材料为例，梳理调整机制及影响因素，探讨铁路信息价与地方信息价差异，提出铁路工程材料价格确定或调差的优化建议，为铁路建设合理控制投资及深化铁路造价标准改革，提供技术支持。
Abstract:
Price adjustment for materials is an important means of controlling investment reasonably in the management of railway construction. Affected by many factors such as topographical and geological conditions, local economy, processing, and transportation, the current national unified price adjustment mechanism cannot truly reflect the actual situation of a project. With the Coefficient of Variation (CV) method, and the case study of the major materials such as cement, steel, and fuel oil in the mountainous provinces in Southwest China such as Sichuan, Yunnan, and Guizhou, the paper analyzes the adjustment mechanism and influencing factors, discusses the difference between the information price of railway sector and the local information price, and proposes optimization suggestions for determining or adjusting the price difference of railway engineering materials, so as to provide the technical supports for rationally controlling investment in railway construction and deepening the reform of railway cost standard.
