Since landing on the Beijing Stock Exchange, the phone number of Shen Ying, the Chief Financial Officer and Secretary of the Board of Directors of Suzhong Co., Ltd., has been ringing incessantly, and there has been a significant increase in investors and customers who have come to visit the group for research. The listing has provided strong support for this needle bearing leading enterprise to explore new markets and new customers. The growth and development of Suzhong Group in the capital market are on par with the stock transfer system and the Beijing Stock Exchange. Having gone through the experiences of the first batch of listed companies, selected layer listed companies, and the first batch of listed companies on the Beijing Stock Exchange after the expansion of the New Third Board, Suzhong Group has solved the problem of development funds in a "new way" and retained technical backbone. The state-owned enterprise "old factory" has gradually become a "small giant" in the industry. A sound multi-level capital market system is a main line of deepening the reform and development of China's capital market. After more than 20 years of development, China's capital market has formed a multi-level market system covering the Shanghai and Shenzhen Main Board, ChiNext Board, Science and Technology Innovation Board, Beijing Stock Exchange, New Third Board, and regional equity markets. The multi-level capital market ecosystem that progresses layer by layer has contributed capital momentum to stabilizing economic growth, supporting technological innovation, and achieving high-quality development. Reform is only ongoing. How to further improve the multi-level capital market system and enhance its compatibility with the real economy? How to further optimize the linkage of sectors and stimulate the upward momentum of enterprises? How can Guangdong leverage the multi-level capital market to "transform" its industries faster and better? With these questions in mind, Southern+journalists have traveled throughout the country to find answers. As soon as Wu Zizhou, Deputy General Manager and Secretary of Yongshun Biotechnology, stepped down from the podium, executives from several "specialized, refined, and innovative" companies "learned from him." If the scale of the enterprise meets the standards of the Beijing Stock Exchange and there is urgent financing demand, the Beijing Stock Exchange may be one of the best choices, "Wu Zizhou actively recommended. The story dates back to 2020. After 4 years of listing on the Yongshun Biological New Third Board, the selected layer of the New Third Board was established. When many companies are hesitant to report to the selected tier, Wu Zizhou insists that they cannot miss the policy dividend period. In 2021, the Beijing Stock Exchange officially opened with the gong, and Yongshun Biological moved from the selected level to the Beijing Stock Exchange with the halo of "the first stock of animal vaccines". The official unveiling and opening of the Beijing Stock Exchange marks the initial formation of a multi-level capital market in China, consisting of the Shanghai Shenzhen Main Board, the Science and Technology Innovation Board, the Growth Enterprise Board, the Beijing Stock Exchange, the New Third Board (innovation layer, basic layer), and regional equity trading centers. Jiayuan Technology has attracted much attention as one of the first three science and technology innovation board enterprises in Guangdong. After the emergence of the Science and Technology Innovation Board, Jiayuan Technology, which was listed on the New Third Board, has set new goals. After 5 days of application, Jiayuan Technology received an acceptance letter from the Science and Technology Innovation Board of the Shanghai Stock Exchange. The listing process was smooth and efficient, "said Liao Pingyuan, Chairman of Jiayuan Technology, with fresh memories. Nowadays, with the initial fundraising projects and fixed increase fundraising projects reaching production one by one, Jiayuan Technology expects the total production capacity to double from 2022 in 2023. For decades, China's capital market has been experiencing ups and downs, forging ahead. The overall requirements for building a multi-level capital market starting from the establishment of the Shanghai Stock Exchange and Shenzhen Stock Exchange are frequently seen in important documents. Especially after the 18th National Congress of the Communist Party of China, the construction of China's capital market took rapid and steady steps. Afterwards, after the establishment of the Science and Technology Innovation Board by the Shanghai Stock Exchange, the reform of the Growth Enterprise Board by the Shenzhen Stock Exchange, the merger of the main board and small and medium-sized enterprises
