摘　　要：电网工程设备材料价格的频繁波动对输变电工程投资及造价管控影响重大,研究设备材料价格的影响因素对于准确把握设备材料价格变化趋势、合理控制工程造价具有积极意义。将设备材料价格的影响因素分为政策因素、经济因素和企业行为3类,结合设备价格及招投标相关数据逐项加以分析,得出各类因素影响设备价格的渠道一是通过影响成本,二是通过影响利润进而影响价格。将影响利润的因素归结为供需关系、竞争模式和招标策略3个方面,将成本归结为原材料成本、人工成本、固定成本、研发成本和融资成本,以期为合理控制工程造价、降低工程投资风险提供参考。The frequent fluctuations of equipments and materials prices have serious influence on the investment and cost control in power grid project. In order to accurately grasp the trend of equipment prices and reasonably control the project cost, it has positive significance to research the influence factors on equipment prices. Combined with the equipment price and the bidding data, these factors are analyzed in this paper, which are divided into three types： policy factors, economic factors and enterprise behavior. The factors affected the equipment prices are mostly through two aspects： cost and profit. Finally, the factors influencing profits could be concluded in three aspects, supply-demand relationship, competition model and bidding strategy; while the cost is mainly concluded into raw material cost, labor cost, fixed cost, development cost and financing cost. The research could provide references for the reasonable control of project cost and the reduction of project investment risk.
