中文摘要：

技术创新是企业获取竞争优势的重要手段，考虑到内在生产成本和外部创新补贴方式的重要性，以企业产品具有可替代性和生产成本具有差异性为前提，分析政府补贴方式对企业创新模型选择的影响．模型解析和数值仿真结果表明：当政府创新投入补贴或者创新产品补贴的水平较低时，成本优势企业群体和成本劣势企业群体都会向选择渐进式创新模式方向演化，而创新产品补贴方式对演化速度的影响更为明显；当政府创新投入补贴或者创新产品补贴的水平较高时，两类补贴方式对两类企业群体选择创新模式的演化方向有不同影响，创新投入补贴会使两类企业群体都向选择突破式创新模式方向演化；创新产品补贴不能有效引导企业选择突破式创新模式，当补贴水平较高时，两类企业群体向渐进式创新模式方向演化的速度较慢．加大创新补贴力度，优化创新补贴结构，建立创新补贴长效机制能够使创新补贴成为有效的创新激励措施．

英文摘要：

Technique intensive innovation is a very important measure for a company to gain advantage in com-petition. With consideration of the importance of internally production cost and externally innovation allowancemethod, this paper assumes that different companies＇ products are substitutable and have different productscosts. We discussed two kinds of companies-one with cost advantage, the other with cost disadvantage-andgovernment＇s two allowance methods-allowance on innovation investment and allowance on product innova-tion project. We analyzed how the two kinds of government＇ s allowance method influence the companies＇choice of their innovation model. The result from our analysis and numerical simulation shows that if the gov-ernment is in a low level of allowance on innovation investment or product innovation project, the two kinds ofthe companies, either in cost advantage or in cost disadvantage, will tend to evolve into the model of graduallyinnovation and the allowance in product innovation takes a great effect on its evolutionary speed. If the govern-ment is in a high level of allowance on innovation invest ment or product innovation project, the influence fromsuch two allowance methods are different for the two kinds of companies＇ innovation model choice; the allow-ance on innovation investment pushes the two kinds of companies to breakthrough their innovation model, butthe allowance on product innovation project shows little effect in guiding companies selecting the breakthroughinnovation model. When the allowance on product innovation project is in a high level, the two kinds of com-panies evolve slowly into the gradual innovation model. Enlarging the scale of the allowance amount, refiningthe structure of innovation allowance, and setting up a long team innovation mechanism all enables the innova-tion allowance to become an effective away of motivation on innovation.
