Xinhua News Agency, June 3, 2020-the first batch of "hard technology" flagship products, Tech Chuang 50ETF, was established in September 2020, and the product scale grew rapidly. By the end of May this year, the total scale broke through the 100 billion yuan mark, achieving a leap of "from 0 to 100 billion" in less than three years. From the author's point of view, there are two major signals behind this, namely, the market's favor for Science and Technology Innovation Board's "hard technology" attribute and confidence in China's high-level science and technology for self-reliance. Science and Technology Innovation Board's opening board is about to expire for four years. In the past four years, Science and Technology Innovation Board's construction has progressed steadily, the market is steady and orderly, attracting many "hard technology" enterprises, and the plate "hard technology" has distinctive features: as of May 31, the three major industries of the new generation of information technology, high-end equipment and biomedicine account for 37%, 22% and 21% respectively, accounting for 80% of the total. Science and Technology Innovation Board listed companies also handed over eye-catching "transcripts": based on 2019, Science and Technology Innovation Board listed companies achieved a compound growth rate of 29% and 56% in operating income and homed net profit in the past three years.
