From the distribution of printed circuit board (PCB) manufacturing application industries in China in 2021, communications, computers and commercial equipment, automobiles, and consumer electronics are the main application fields, accounting for 31%, 27%, 16%, and 15% respectively.
The scale of business in the communications market has grown steadily
Electronic communication equipment, abbreviated as ICD, is a wired communication equipment and wireless communication equipment used in industrial control environments. In recent years, people’s demand for the Internet has grown rapidly, and the rapid growth of Internet traffic has become a key factor in driving information infrastructure. Investment in information infrastructure such as operators has further accelerated. The rapid development of optical communication technology has provided reliable technical support for information infrastructure.
According to the data, from 2017 to 2022, the scale of business revenue in China’s communications industry showed a slow upward trend, about 1.73 trillion yuan in 2022, a year-on-year increase of 9.48%. At present, the industry lacks replacement products, and the market demand is basically saturated, but with the accelerated application of new technologies such as 5G, the industry is expected to usher in a new period of growth. 
The output scale of the computer market first increased and then decreased
From 2017 to 2022, the scale of China’s electronic computer production will first rise and then fall. In 2021, the output scale of electronic computers in China reached 485 million units, a year-on-year increase of 19.84%; In the first 11 months of 2022, China’s electronic computer production was 399 million units, and the overall production scale is expected to decline significantly in 2022.
The scale of production and sales in the automotive market increased slightly
From 2015 to 2022, the scale of China’s automobile production and sales basically showed a trend of first rising and then declining, while the production and sales of each year were more matched, and the production and sales rate was better. In 2021, China’s automobile sales volume was 26.275 million units, a slight increase of 3.81% year-on-year, and the production scale in the same period was 26.082 million units, sales exceeded production, and inventory decreased. In the first 11 months of 2022, vehicle sales in China reached 23.4 million units, up 3.3% year-on-year. Overall, the automobile market is mature, and the scale of production and sales has increased slightly in the past two years.
The consumer electronics market has shrunk
From 2017 to 2021, China’s tablet shipments showed an overall upward trend. According to the data, in 2021, China’s tablet shipments were 28.46 million units. Compared with the world, in addition to the large increase in demand caused by the new crown epidemic, the Chinese market penetration rate is also low. In the first half of 2022, China’s tablet shipments reached 14.01 million units, a slight increase year-on-year; However, since entering the second half of the year, sales in the third quarter have fallen by 4.5% year-on-year.
From 2016 to 2022, the scale of China’s smartphone shipments basically showed a downward trend, and the development of the industry is very mature. In 2021, smartphone shipments reached 343 million units, a year-on-year increase of 15.9%, mainly due to the demand for online office stimulating the growth of consumer electronics such as mobile phones. In the first 11 months of 2022, China’s smartphone shipments were 237 million units, down 23% year-on-year.
