The Calculation Of Used-cars' Residue Rate In Replacement Cost Method

In recent years, China's auto industry and gain a rapid development, in 2014 the number of cumulative sales of new cars is twenty-three million four hundred and ninety-one thousand and nine hundred, with an increase of 6.9%, for 6 consecutive years the world's first. Meanwhile, the rapid development of the new car market also contributed to the development of the used car market, in 2014 the whole year the amount of second-hand car trading volume, compared to the same period last year increased by 16.33%, whose number is six million fifty-two thousand and nine hundred, what is expected to break ten million in 2016.Although the second-hand car market has developed rapidly, but our country used car market is still in the initial stage, there are many non-standard place. Therefore, a lot of problems appeared in the assessment of second-hand car at times, especially in the replacement cost method, how to determine the residue rate of second-hand car is an important problem that besetting the practitioners and consumers for a long time. In practical applications, a residue rate of determination should be based on a large number of used car historical data. For some long time, many trading models, the data can be easily found in the market to infer its new rate, but because of the rapid development of China's automobile industry, a large number of new models have been produced and sale on the market, for these models, which are lack of historical data for reference, it is difficult to determine their residue new rate.In view of this problem, this paper in reference to domestic and foreign trade data, combined with our market situation and data, select cluster analysis from variable statistical methods and put forward a residue rate calculation model. According to the analysis results, the corresponding regression equation is established for each type of vehicle. By using this model, we can obtain the residue rate data by analyzing the relevant factors, so as to determine the evaluation value of the second-hand vehicle. Theoretically, this model can be used to provide a strong reference value for the assessment of the used car.
