The invention provides a price parameter generation method and device of a power grid project equipment material. The price parameter generation method comprises the following steps: selecting a plurality of primary selection models from a preset model library based on a time dimension and a price volatility; selecting at least one final selection model from the plurality of primary selection models according to a plurality of preset indexes; and judging whether the number of the at least one final selection model is greater than 1, and if so, performing equal weight combination calculation by using the at least one final selection model to obtain comprehensive price parameters of the power grid project equipment material. According to the price parameter generation method and device of the power grid project equipment material provided by the invention, as a plurality of influence factors and a plurality of indexes of the price of the power grid project equipment material are comprehensively considered, compared with the traditional simple price statistical approach, the generated comprehensive price parameters are more accurate, and the price prediction risks of enterprises are reduced.
