Downstream Application observation: The Internet of Things is coming! According to IDC's forecast, 30 billion devices are expected to access the Internet of Things by 2020, and the market size of the Internet of Things will increase from 265. 6 billion US dollars in 14 years to in 2020. $4 trillion. We believe that the internet of things is still in its infancy. On the one hand, there is a large demand for public infrastructure of the Internet of Things: therefore, it can be laid out as the perception layer and communication layer of the internet of things; On the other hand, the downstream demand is huge, so the focus is on the layout of the existing Internet of Things heavyweight entrance mobile phones, potential new important entrance automotive electronics, VR/AR, etc. Observation of industrial chain links: localization of equipment materials, China's electronics industry is making upward efforts! China's electronics industry has started a new round of industrial upgrading, step by step from complete machine assembly to peripheral spare parts, from design and manufacturing to localization of core equipment and materials. Taking China's semiconductor industry as an example, in order to realize a completely autonomous and controllable Road, the Chinese government and industrial forces are actively mobilizing policies, manpower, capital, markets and other resources to promote the transfer of the semiconductor industry to the mainland, and the mainland Semiconductor has ushered in rapid regional growth, it brings strong demand for related equipment and materials. Focus on PCB industry: benefit from the improvement of supply and demand structure and enjoy the price increase cycle. In the past two years, the supply-demand relationship in the PCB industry has undergone profound changes. The industry as a whole has recovered and entered a new round of economic cycle. The upstream raw material copper foil entered the price increase cycle driven by the lithium battery market, and copper clad plate and PCB manufacturers obtained new pricing opportunities, leading enterprises with bargaining advantages will stretch their profit margins in the process of shifting the pressure of rising raw material costs and gain performance elasticity. In the downstream PCB application field, the PCB demand market in many sub-sectors has achieved double-digit annual growth rate, becoming the new growth momentum of PCB industry. From the perspective of LED industry cycle: LED has entered a stable growth era from full competition, and Chinese brands have moved to the world. After 15 years of deep reshuffle, the supply-side reform has been relatively sufficient. The LED industry has been in the second wavelength of the S-type industry curve: From the perspective of LED upstream supply, the concentration of industrial production capacity has accelerated, forming higher industrial barriers and curbing disorderly expansion of production capacity; At the same time, downstream application innovation drives the vigorous development of the industrial chain. From the current point of view, LED lighting will increase by more than 10 next year, and LED lighting will increase market space by 1. 5%. Three times, and the accelerated 24-year growth shown by small spacing, is becoming the main driving force for the new round of LED industry demand prosperity.
