摘    要:基于汽车等速100 km油耗、最高车速和0~100 km/h制动距离等基本技术性能指标,以及发动机排量、整车质量和售价等参数构建技术性能指标H、综合参数W和性价比N,形成多维综合评价方法,并提出一种以W为特征参数的汽车标识方式。在此基础上,对我国汽车市场主要品牌车型的技术性能、性价比等参数与销量之间的相关性进行研究。研究结果表明:不同品牌及车型的技术性能存在明显差异,合资品牌汽车技术性能比国产品牌的优,但性价比却显著比国产品牌的低;消费者对轿车、SUV和MPV的选择标准也存在差异,消费者选购轿车时更看重产品的技术性能和品牌;选购SUV时,消费者更关注产品的综合性能,而选购MPV时,消费者则更注重产品的实用性和性价比;高性能小排量发动机、高容量电池和电机系统、汽车轻量化与智能化及驱动技术(油电混合、增程式,尤其是四驱技术,驱动与制动系统一体化)的重大突破有望促成我国汽车产业跨越式发展。

Abstract: A multidimensional evaluation scheme was constructed consisting of a technical performance indicator H, a mass-weighted measure of the effect of the technical parameters W and a measure of the price efficiency N.These indexes were functions of primary performance indicators,which included constant speed fuel consumption,braking distance in the maximum speed 0-100 km/h, engine volume, mass and price.Vehicle indetified method was proposed taking W as the most useful indicator for comparing different vehicles and models. The correlations between the technical performance, price and sales of several major car models in Chinese market were studied.The results show that different car models have significantly different performance indices with joint-venture generally outperforming domestic ones on technical performance, but underperforming on price. There are distinct differences in consumers’ selection criteria for cars, SUVs and MPVs. Consumers care more about the technical performance and brand of products for cars,while they care more about the comprehensive ability for SUVs, practicality and cost-effectiveness for MPVs. Breakthrough in high performance and small engines, high capacity battery and motor system, light weight and intelligent vehicles and driving technology (oil-electric vehicles, extended-range vehicles, especially all-wheel drive and integration of driving and braking system) can boost the Chinese vehicle industry development.
