This study addresses the special characteristics and limitations of Chinese enterprises in innovation performance evaluation, and analyzes in depth the unique needs and challenges of these enterprises in the process of technological innovation. By comparing relevant research and practices at home and abroad, this paper proposes a comprehensive set of enterprise technology innovation performance evaluation index system. This study not only helps the management of enterprises to formulate and adjust their technological innovation strategies, but also promotes the improvement of their internal innovation mechanism and culture. In this way, enterprises can allocate and utilize resources more effectively, optimize products and services, and ultimately enhance their overall technological innovation capability and market competitiveness. The enterprise technological innovation performance evaluation index system constructed in this study not only provides a practical technological innovation evaluation tool for enterprises, but also provides policy makers and academics with a new perspective and methodology for studying enterprise technological innovation. This will help promote the continuous development and progress of Chinese enterprises in technological innovation.
