The factory fell into labor shortage, and the three major indicators of shipbuilding increased steadily.

Benefiting from the dividend of the population and the low labor cost, China's factories have been greatly developed. However, in recent years, when young people are unwilling to work in factories and more migrant workers choose to stay in their hometown, the problem of labor shortage across China has occurred frequently, making factories suffer from labor shortage. Especially in 2020, the outbreak of infection with COVID-19 will make labor even more scarce. According to the 2020 Migrant Workers Monitoring and Investigation Report released by the National Bureau of Statistics on April 30, 2021, the number of migrant workers in China in 2020 decreased by 5.17 million compared with 2019.
At the same time, with the development of the Internet of Things, intelligence and intelligence, smart factories are the general trend of modern industry and manufacturing, and an optimization path to achieve enterprise transformation and upgrading. In the next few years, China's smart factory industry will maintain an annual growth rate of more than 10%. The data shows that the market size of China's smart factory will reach 856 billion yuan in 2020, and it is expected that the market size will reach 951.9 billion yuan by 2021.
