The reporter learned from the Traffic Management Bureau of the Ministry of Public Security on the 2nd that, as of the end of March, the number of motor vehicles in China was more than 170 million vehicles. In the first quarter, it increased by an average of 32,000 vehicles per day, and the number of cars under 1.6 liters increased significantly.
According to the data provided by the Ministry of Public Security Traffic Control Bureau, the increase in motor vehicle ownership in January was small due to the impact of the international financial crisis, but it was subject to the government's introduction of fuel tax reforms, downsizing of small-displacement vehicle purchases, and automobile and motorcycle going to the countryside. As a result, the growth rate of motor vehicle ownership has increased month by month. In March this year, the monthly increment of motor vehicles has exceeded the level of the same period of last year. The ownership rate of private cars has gradually increased. The ownership of private motor vehicles in the country accounts for 76.49% of the total number of motor vehicles. The increase in passenger cars and light trucks by 1.6 liters was significant. The number of small and micro passenger vehicles in the country increased by 5.58% from the end of last year, an increase of 21.68% compared with the same period of last year.
