摘　　要：针对舰船维修具有的异质性特点导致"纯样本匹配法"并不适用于舰船维修价格指数编制的问题,首先提出采用特征价格理论,选取舰船维修特征属性并给出了量化处理原则;然后,利用合并数据特征价格建模方法,建立了舰船维修线性Hedonic价格指数模型,并针对线性模型拟合精度不高等问题,通过多种形式的Box-Cox转换,构建了舰船维修的非线性Hedonic价格指数模型,得出了舰船维修Hedonic价格指数,以反映舰船维修的"纯价格变化"趋势。最后,与通过"纯样本匹配法"获取的价格指数进行比较,并解释了二者的差异性。Because of the heterogeneous characteristics of ship maintenance, the pure-exemplar matching method is not suitable for the ship maintenance price index compilation. Therefore, this paper proposes the Hedonic price theory, determines the altributes of ship maintenance and presents the principle of quantizing treatment. On this basis, a linear model of ship maintenance Hedonic price index is established with the combined data modeling method. Considering the effect of the linear model is not preferable, a non-linear Hedonic model is constructed by the Box-Cox transformation to obtain the Hedonic price index of ship maintenance. Finally, this Hedonic price index is compared with that acquired by the pure-exemplar matching method.
