Incentives for Innovation and R&D
The Company and its subsidiaries have created a comprehensive, multi-level incentive system for innovation and R&D,
designed to precisely stimulate the innovative vitality and creative potential of our scientific and technical personnel. At
the project R&D level, we have established a special performance bonus fund for R&D. Projects are classified into five
grades based on technical difficulty, completion quality, and economic benefits, with total award amounts ranging from
RMB 5,000 to RMB 150,000. The final bonus amount is determined by assessing performance across three dimensions:
progress, quality, and cost control. At the commercialization level, special awards are given to teams or individuals for
innovative achievements such as receiving science and technology progress awards at various levels, technical innova-
tion awards, key new product certifications, and project approvals. For instance, a national-level Science and Technology
Progress Award carries a bonus of RMB 10,000, while an international-level Technical Innovation Award is rewarded with
RMB 20,000. Simultaneously, we integrate diverse incentive methods, including compensation, equity incentives, career
planning, and promotions. By deeply linking innovative contributions to employee salaries, benefits, and career develop-
ment, we have built an incentive mechanism that covers the entire chain of patent creation, project R&D, and commer-
cialization. This continuously drives the efficient output and application of innovative achievements.
Collaborative R&D Mechanism
To further enhance the Company’s innovation capabilities and R&D level, while also contributing to the improvement of
teaching quality and research capabilities at universities, the Company actively promotes university-enterprise cooper-
