China recently has been through a quick economic development, in which its GDP went up and has influenced people’s lives. This paper is written to present the income elasticity of growing GDP and people’s purchasing power on imported cars which is due to their incomes. As well as the demand elasticity of imported cars due to the GDP growth, and the effective rate of imported car parts of imported cars will be concluded as well. Therefore a single regression is recommended to be used to analyze both the first and secondary data that were collected under a 95% significant level. In the research, 11 variables were used to testify the demand elasticity which are number of imported cars; number of imported oil; GDP per capital; GNI per capital PPP; final consumption; rural population; the average imported car price; number of individual vehicles; unemployment and number of motorbike sold. Based on the final results, it shows that there is a considerable demand of imported cars in China. Furthermore, with the development of China’s economy in the future, there is still much space for the demand of imported cars to grow.
