According to flush data, as of February 23, 66 listed companies on the science and technology innovation board have taken the lead in disclosing the 2022 performance report. During the reporting period, 47 companies achieved an increase in net profit attributable to the parent company last year, accounting for 71.21%, with a total net profit of 22.268 billion yuan. Liu Xiangdong, deputy director of the Economic Research Department of the China Center for International Economic Exchanges, said in an interview with the reporter of Securities Daily that according to the disclosed data, the overall performance of listed companies on the Science and Technology Innovation Board was excellent, indicating that the development driven by science and technology has a strong endogenous force, which effectively promoted the transformation of scientific and technological achievements. According to the performance report, the net profit attributable to the parent company of the 47 science and technology innovation board companies, including Tongyizhong, Xinyuan Micro, Youyan Silicon, Microelectrophysiology and Hanchuan Intelligent, all increased by more than 100% year on year, with a total net profit of more than 800 million yuan. "While guaranteeing the orders of key customers in the civil market, the company has increased the development of the composite market. Both UHMWPE fiber and composite materials have achieved the increase of gross profit margin and sales revenue, which has led to a substantial increase in the company's operating performance," Tongyizhong said in its performance bulletin. According to the data, Tongyizhong achieved a total operating revenue of 616 million yuan last year, an increase of 86.26% year on year; The net profit attributable to the parent company was 172 million yuan, up 226.74% year on year. "The company provides wafer foundry and technical services from 0.35 micron to FinFET different technology nodes to global customers." According to the electronic industry leader SMIC International Performance Express, the company's operating revenue leapt to 7.2 billion US dollars last year, up 34% year on year, achieving more than 30% annual growth in 2021 and 2022. In addition, the gross profit rate increased to 38% in 2022, a record high. "The research and development of MEMS hydrogen/VOCs sensors for hydrogen energy safety and lithium battery thermal runaway applications has achieved mass production, and the downstream customers are currently in the verification stage." Kuai Yun, director secretary of Yuanchen Science and Technology, told Securities Daily that technology-driven development has a strong endogenous force, and scientific and technological achievements have laid an important foundation for the company's future growth. "As an important monomer and intermediate, 1,3-propanediol is mainly used to synthesize PTT. Limited by domestic industrialization technology and mass production bottleneck, China's 1,3-propanediol still mainly relies on imports, with the import dependency of about 78% in 2020, and the imported products are mainly from DuPont." Dong Mifanyi of Huaheng Biological told the reporter of Securities Daily that in 2022, the company successfully broke through the technological process of producing 1,3-propanediol by biological method, In addition, an industrial production plant with an annual output of 50000 tons of 1,3-propanediol will be built. After the completion of the project, it will help to solve the problem of "stuck material" in the PTT production process. In the view of Secretary Shao Sen, the director of Onestone, the new energy industry has developed rapidly. As a supplier of lithium battery coating materials, the company will form a synergy between its main business and core technology, closely follow the application needs of customers, and continue to improve the market share of products through technological innovation. Liu Xiangdong believes that most of the listed companies on the Science and Technology Innovation Board have received "hard technology" support. The higher the "scientific content" of the company, the more market attention, the more sustainable the excellent performance. (
