How is the company's R&D investment in the first half of 2023?

Desay SV's answer: In the first half of 2023, the company invested 959 million yuan in R&D, accounting for 11% of sales. High-level R&D investment is not only necessary for developing 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.
