一是设立了机动车登记证书制度。随着经济活动的增加，社会上有关部门、单位和个人给证明车辆合法行驶的机动车行驶证，赋予了财产所有权的证明作用。这种做法，既不规范，也缺乏法律依据，难以保障经济活动中当事双方的权益。因此，迫切需要设置一种证明机动车所有权的文件。 First, the establishment of a motor vehicle registration certificate system. With the increase of economic activities, relevant departments, units and individuals in the society have given motor ownership certificates to prove that vehicles are traveling legally. This approach is neither normative nor legal basis, and it is difficult to safeguard the rights and interests of both parties in economic activities. Therefore, there is an urgent need to set up a document proving the ownership of a motor vehicle.
