中文摘要：

提出技术创新力的概念,并将此分为2个维度：技术创新强度及技术创新潜能。在此基础上,建立了研究框架,采用数学模型和实证分析研究了集群内部竞争对企业技术创新绩效的影响。结果显示,集群企业内部竞争对企业技术创新绩效兼具推动和阻滞作用。随着竞争的加剧,迫于竞争压力,企业会增加技术创新强度,但也使得每个集群企业可用于技术创新的资源减少,从而导致技术创新的潜能下降;进而导致集群内部竞争对集群企业的技术创新产生了倒U型的影响。

英文摘要：

This paper puts forward the concept of innovation power,which is divided into two dimensions of innovation strength and innovation potential.The research framework is then established and the model involving the influence of internal competition on technological innovation is established and empirical analysis is conducted.The results show that the internal competition of enterprises has both positive and negative effects on technological innovation.On one hand,the competition can make enterprises carry out innovation contests,thus enterprises＇ innovation inputs are increased;on the other hand,each enterprise＇s profit decreases with the intensified competition,thus decreased resources are used to innovate and an inverted U-shaped relationship is formed up.
