中文摘要：

汽车经济是一种典型的社会性增长经济，它具有加速度发展的特性。湖南汽车业占GDP的比重逐年上升，但是，以湖南省2002年和2007年的投入产出分析表为基础，进行的汽车产业经济关联效应和产业波及效应的测算结果表明，对比2002年，湖南汽车产业2007年的完全消耗系数和影响力系数均有所下降，说明汽车产业对经济的带动作用呈减弱趋势，配套行业没能跟上汽车行业的发展，汽车产业对经济带动能力的提升受到限制。

Auto economy, which possesses the characteristic of the acceleration of development, is a type of typical social growth economy. Based on the Input and Output Analysis Table of Hunan province in 2002 and 2007, we have measured and calculated the economic association effect and industry spread effect in automobile industry. The results show that ： automobile industry in Hunan province has played a sig- nificant role in promoting economic development and will have great potential to it. However, we should note that complete consumption coefficient and influence coefficient in 2007 have experienced a downturn compared with those in 2002, which indicates that economic pull from auto industry weakens, the ability of auto industry to drive economic development is curbed, and that supporting industries has not been able to keep up with the development of auto industry,
