How is the company's R&D investment?

Desay SV's answer: The company's R&D expenses from January to September 2023 were 1.379 billion yuan, a year-on-year increase of 25.95%, accounting for 9.53% of sales, a year-on-year decrease of 1.30%. High-level R&D investment is not only a necessary investment for the development of new businesses, maintaining technological leadership, and maintaining high-quality sustainable development in the future, but also to meet the current rapidly growing business scale and more complex project product delivery needs. With the continuous reform of the R&D system for many years, the company's R&D efficiency has continued to improve. With the deepening of reform, greater efficiency potential will be tapped in the future.
