The main reasons for the rapid increase in demand in the heavy-duty truck in China this year are: (1) during the epidemic at the beginning of the year, a large number of infrastructure projects such as makeshift hospitals were launched, as well as new infrastructure stimulus policies, which greatly increased the demand for heavy truck construction projects; (2) According to the analysis of Citic Securities, the early elimination of GUO3 diesel heavy duty automobiles promotes the upgrading of heavy duty trucks. Some regions begin to restrict the operation of Guo4 vehicles, and the overload control in many places becomes stricter, which promotes the rapid increase of the demand for compliant heavy duty trucks, standard heavy duty trucks and lightweight heavy duty trucks.
