Could you please introduce the company’s R&D investment?

Yingboer replied: The company has always positioned itself as an innovation-driven enterprise, and insisted on taking the path of independent research and development and technological innovation. R&D investment is an important driving force to ensure the company's development. During the reporting period, the company invested 42.3505 million yuan in R&D expenses, accounting for 10.06% of the current operating income. In 2019, the R&D investment was 52.4681 million yuan, accounting for 16.47% of the operating income. In 2020, the investment decreased by 10.1176 million yuan compared with the previous year. The main reason is that in 2019, in order to expand more customers and models against the trend, the company invested heavily in product platform construction. In 2020, the company's platform construction was basically completed, and R&D investment decreased compared with 2019.
