As the growth rate of China’s auto market declines，the contribution of replacement to new car sales is increasingly prominent，and the era of replacement is coming. At the same time，in the context of the continuous improvement of the national economic strength，consumption upgrades also have a clear performance in the replacement process，and the replacement market will become the main battlefield for the future competition of major brands of passenger cars. Therefore，grasping the characteristics of replacement flow and loyalty performance under the background of consumption upgrade will not only help to understand the current passenger vehicle market，but also provide important assistance for the future product layout，marketing and brand building of automobile companies.
