Due to the development of new energy vehicle industry, the global power battery industry is developing rapidly. According to iiMedia Research, the global installed capacity of power batteries reached 92.5GWh in 2018, up 45.8% year on year. The market share of the world's top ten power battery enterprises reached 88.7%, and Ningde times, Panasonic and BYD have occupied the top three positions in the market for two consecutive years. Meanwhile, China's power battery industry has entered a stage of rapid development. In 2018, the scale of China's power battery market has exceeded 82 billion yuan, and China's power battery market is highly concentrated. The installed capacity of top ten enterprises has reached 83.2% of the total. As a derivative industry of the power battery industry, China's battery recycling industry is at the initial stage, and has formed two models of producer-led recycling and professional third-party recycling. In general, the automobile power battery industry presents four trends: first, the production and sales volume continue to grow rapidly, and the industry concentration increases in the competition; Second, the sales price of power battery system has been greatly reduced, and the upstream material has become a key factor; Third, the development of power battery is good, but the frequent occurrence of negative events is still worrying; Fourth, the recycling route of power batteries is becoming clearer, and the commercial system still needs to be improved.
Driven by favorable policies, technological advancement and market demand, the global Ultra HD industry is developing at a high speed. In 2018, global 4K TV shipments reached 102 million units. Although China's Ultra HD industry started late, 4K terminal equipment has a leading edge. The penetration rate of China's 4K TV has reached 58.0% in 2018 and is expected to reach 71.0% in 2021. At present, China Ultra HD has formed three major industrial chain links including core component manufacturing, terminal rendering equipment manufacturing and content production and production. In the first three quarters of 2018, the revenue of six 4K concept stock listed companies exceeded 10 billion. Yuan, of which, TCL Group's revenue reached 82.24 billion yuan, becoming the first share of China's 4K concept. According to iiMedia Research, the Guangdong region is most concerned about the Ultra HD industry. The related listed companies, BOE A (000725.SZ), have the highest network attention, and China Digital Media (000156.SZ) has the best network reputation. With the development and application of 5G technology, which is driving China Ultra HD industry into the fast lane of development, iiMedia Consulting analysts believe that the future 4K display technology will have more innovative integration in the fields of culture, education, entertainment, industrial manufacturing, medical health and transportation area.
