摘要
汽车保值率是衡量车辆价值衰减快慢的重要指标,针对具有自身特点的新能源二手车,进行二手车保值率预测。应用分层聚类的方法将目前市场占有率较高的15种新能源车型的保值率进行分类,聚类筛选出保值率相接近的车型,并建立其保值率回归曲线方程,经计算具体预测数值与实际市场值一致。
The automobile hedging rate is an important index to measure the fast decline of vehicle value.For the new energy used vehicles with their own characteristics,the paper forecasts the maintenance rate of used vehicles.The paper classifies the hedging rate of 15 new energy models with high market share by hierarchical clustering,selects the models with similar hedging rate and establishes the regression curve equation of the hedging rate.The calculated results are consistent with the actual market value.
