摘　　要：根据样本分析需要,选取近年国网已竣工投产的40条典型500 kV输电线路工程为样本。对工程本体造价关键影响因素进行阐述,采用spss软件对关键因素进行回归分析,识别线性与非线性影响因素,运用多元线性回归法和系数调整法,将两种性质的关键因素度考虑进模型设计中,建立输电工程造价综合预测模型,最后对所得模型进行样本分析检验,确立造价综合预测模型,有效预测控制输电工程造价。Forty typical 500 kV transmission line projects were selected as samples to study the key influencing factors of project cost. The SPSS software was used to recognize the linear and non-linear influencing factors, and the multi- ple linear regression method and the coefficient adjustment method were used to establish the comprehensive prediction models for transmission engineering project cost.
