This dataset is an index reflecting the price change trends of used cars in the Chinese used car market, serving as a critical reference indicator for China's pre-owned vehicle market conditions. This index is generated using a geometric exponential algorithm, based on nationwide online used car listing data after undergoing data cleaning and processing. Specifically, data cleaning includes removing duplicate and invalid car listings; data processing covers vehicle model matching, screening for stable samples, and listing price adjustment, among other steps. The advantage of the geometric exponential algorithm is that it can effectively filter out price fluctuations caused by factors such as region, vehicle age, mileage, and vehicle model combinations, thereby more accurately and objectively reflecting the actual dynamics of used car price changes. Additionally, this index can reveal price change trends across various dimensions including brand, market segment, and fuel type, enabling used car operators or researchers to comprehensively understand the real price trends of the used car market. Its application scenarios include used car operations in relevant departments of automobile manufacturers, procurement and sales operation management for used car dealers, and consumers' purchasing decision-making, among others.
