   According to Article 11 of the Road Traffic Safety Law of the People's Republic of China: Motor vehicles driven on roads shall display license plates, inspection合格标志 (inspection合格标志), insurance marks, and carry vehicle registration certificates. License plates must be clearly and completely displayed without intentional obstruction or damage. No entity or individual may confiscate or detain license plates. Vehicle registration serves both to facilitate traffic management by public security authorities and to enable public oversight.

   In addition to provincial/municipal vehicle registration statistics, this database systematically organizes brand, model, and other vehicle series information for registered vehicles. This enables researchers to analyze regional new vehicle registration trends while enhancing insights into brand market dynamics and consumer purchasing preferences.

   The CnOpenData team has compiled nationwide urban vehicle registration records since 2017, with detailed fields including vehicle model (车型), brand (品牌), place of origin (产地), and other critical attributes to support academic and industrial research.
