全国二手汽车保值率数据

根据二手汽车的车型信息，从保值率计算模型的函数数据库中获取对应的函数，计算获得二手汽车在认证二手车和拍卖二手车两个渠道的市场平均保值率数值；其中，车型信息包括型号、上牌时间、里程、车况、交易地点和/或颜色；同时，该模型可分不同车龄年限，从品牌、车系、年款等多维度，计算出其对应的保值率数值。保值率数据准确度高，多渠道、多维度统计分析，且稳定性强，可以相对准确地计算获得二手汽车的市场平均保值率，可广泛应用于二手汽车交易行业的参考当中。

Based on the vehicle profile information of used cars, the corresponding functions are retrieved from the function database of the residual value calculation model to calculate the market average residual value rates of used cars across two channels: certified pre-owned (CPO) vehicles and auctioned used vehicles. The vehicle profile information includes model type, registration date, mileage, vehicle condition, transaction location and/or color. Meanwhile, this model can compute the corresponding residual value rates from multiple dimensions such as brand, model series and model year, based on different vehicle age ranges. The residual value dataset features high accuracy, multi-channel and multi-dimensional statistical analysis capabilities, and strong stability, which enables accurate calculation of the market average residual value of used cars, and is widely applicable as a reference for the used car trading industry.
