由中汽协统计出的“非完整车辆”相当于一直习惯称谓的改装(车)用底盘,但不能称其为专用汽车底盘,因为其绝大部分被改装成专用汽车(含专用货车、专用作业车及专用客车)、极少部分被改装成普通客车。可以说,“非完整车辆”的市场走势总体上反映了一个“时期”后整个专用汽车市场走势,从而透过前者可前瞻性地研判后者。至于这个“时期”有多长?取决于“非完整车辆”被改装成专用汽车(及客车)并被销售出去的周期。 The “incomplete vehicle”, which is calculated by the Association of Automobile Manufacturers, is equivalent to the chassis used for modified cars that have been customary, but can not be called a special-purpose vehicle chassis because most of them are converted into special purpose vehicles , Special operation vehicles and special buses), a very small part was converted into ordinary passenger cars. It can be said that the market trend of “non-complete vehicles” generally reflects the trend of the entire private car market after a “period” so that the latter can be prospectively judged. How long this “period” depends on the “incomplete vehicle” is converted into a dedicated car (and bus) and sold out of the cycle.
