On November 15, the 24th China International Hi tech Fair (hereinafter referred to as the "High tech Fair") with the theme of "Scientific and technological reform drives innovation and scientific and technological innovation drives development" was opened in Shenzhen. The CHTF attracted more than 5600 exhibitors and more than 8600 projects from 41 countries and regions. This year's High tech Fair is the first time to set up a water-saving high-tech achievements exhibition and hold the first national water-saving innovation and development conference to highlight the concept of green development; The online exhibition system has been further upgraded, integrating the functions of exhibitor exhibition, trade project exhibition, cloud forum, highlight recommendation of theme tour routes, etc., to provide exhibitors with systematic, diversified and digital online exhibition functions. In the Guangdong Mission Exhibition Area, 112 units from provincial laboratories to various high-tech enterprises appeared, displaying 180 project achievements, attracting many visitors. Among the Guangdong group exhibitors, 82 are high-tech enterprises of all types, accounting for 73%, reflecting the dominant position and important role of enterprises in Guangdong innovation. "We select enterprises in the fields of new generation information technology, 5G, and meta universe to demonstrate the specific application of 'digital technology+real economy' in social livelihood, government services, and smart life." Said the staff of the Guangdong Youth League. Focusing on the theme of "Cohesion to promote high-level scientific and technological self-reliance" and centering on the theme of accelerating the construction of the whole process innovation ecological chain of "basic research+technological breakthrough+achievements transformation+science and technology finance+talent support", the Guangdong Delegation set up three display plates, namely, key display plate, provincial strategic scientific and technological force layout plate, and provincial and municipal scientific and technological project achievements plate, to display Guangdong's scientific and technological innovation and development achievements from multiple perspectives, such as production, learning, research, and enterprises. The high refractivity transparent ceramic material developed by Songshan Lake Materials Laboratory is a kind of preferred new material in the field of display panel. The project realizes the localization of the whole chain from raw materials to equipment, and the process is self-developed, with core independent intellectual property rights. Taking Songshan Lake Materials Laboratory as the representative, the Guangdong delegation, centering on the whole process of innovation ecological chain, planned and laid out to show the achievements of building a strong province of scientific and technological innovation, and created a characteristic exhibition area in the form of "physical sand table+real-time interaction+exhibition board display+live performance". The concentrated demonstration of the construction progress of the International Science and Technology Innovation Center in the Guangdong Hong Kong Macao Greater Bay Area is another major feature and highlight of the Guangdong delegation. In the form of physical sand table, the site showed the overall situation of the construction of the International Science and Technology Innovation Center in the Guangdong Hong Kong Macao Greater Bay Area, as well as the construction progress of major innovation carriers such as Guangdong Major Innovation Cluster, National High tech Zone, Major Science and Technology Infrastructure, Major Innovation Platform, the Comprehensive National Science Center in the Greater Bay Area, and the Guangzhou Shenzhen Hong Kong Macao Science and Technology Innovation Corridor. The High tech Fair will last for five days, during which a number of high-quality professional forums will be organized and planned, including "New Era, New Technology, New Economy", "Hello, Meta Universe" and other theme forums, introducing China Internet Conference, Global 5G Development Conference, China Nuclear Energy High quality Development Conference, Human Resources Summit Forum, etc. Many academicians gave speeches at the 2022 Strategic Emerging Industry Cultivation and Development Forum and the "Science and China" academician and expert lecture tour.
