中文摘要：

通过引入不完全信息离散博弈模型,借助数值模拟与反事实分析考察了扩张成本与产品线扩张对本土轿车产业竞争策略的影响。结果表明：产品线扩展提升了企业市场份额和盈利能力,扩张成本则会起到一定的抑制作用。具体表现在：由于产品线扩展的后发优势,本土企业在小微和紧凑市场上具有比较优势,在中大市场上则因高昂的扩张成本处于劣势。一个策略性建议是：在外资企业品牌、技术等全面占优的情形下,本土企业应该进行差异化的细分市场定位,借助产品线扩展实现战略突围,加大力度切入中小和紧凑市场,侧重于低价和精品策略,慎重介入中大市场。

英文摘要：

Introducing a discrete game model with incomplete information, this paper investigates the influence of expansion cost and product line expansion on the optimal competition strategy of local car industry by numerical simulating and inverse anglicizing. The result shows that product line extends to enhance the market share and profitability, and the expansion of the cost will play an inhibition role. A suggestion is that local enterprises should be differentiated subdivision market position and breakthrough by product line extension, intensify start small and compact market, and focus on the low-cost and high - quality goods market, careful into the big market.
