After the in-depth integration of the industry in 2015 and 2016, the LED supply-side reform has been relatively sufficient. In 2017, the LED industry showed a good start. Sanan Optoelectronics, the leader of the chip, announced that the price increase boosted the plate market. With the double promotion of strong demand and rising costs, the price increase is expected to continue. it is expected that the industry's structural surplus will be further improved in 2017. The small spacing with higher technical barriers indicates that the industry will accelerate its growth and the industrial concentration will further increase. At present, from the perspective of the upstream of LED, the concentration of industrial production capacity is accelerating, and higher industry barriers are formed to curb disorderly capacity expansion; Mid-end packaging technology continues to innovate, reducing costs and improving efficiency; The downstream of the industry is booming under new applications such as vehicles, lighting, small-pitch LED display and internet of things. The industry of the entire industrial chain is expected to start a new round of growth. According to media reports, the LED concept sector has been active recently, with 50 concept stocks in the sector rising, accounting for 76. 92. Among them, Helen Zhe, Keheng, Jiawei, Wanrun technology, maoshuo power, zhouming technology and other stocks were among the top gainers, respectively. 22, 3. 05, 3, 2. 85, 2. 74 and 2. In addition, hengshun Vinegar Industry, Abison, Guangdong Ganhua, Guoxing Optoelectronics, langke intelligence, sunshine lighting, Dongshan Precision, yingfeite, Lianchuang Optoelectronics, Aoyang Shunchang, * ST Zhongfa, xinhaiyi, Tongyi, xuelaite, Xiamen Xinda, Linyang individual stocks such as energy, Qianzhao Optoelectronics, MEDA digital, * ST Dongjing also performed well. these stocks all rose by more than 1. With technological innovation and cost reduction, LED downstream applications are accelerating, and lighting has become a large downstream application market for LED. The agency predicts that the LED lighting market will reach 29. 6 billion US dollars in 2016 and is expected to reach 33. 1 billion US dollars by 2017, with a market penetration rate exceeding 52. In this context, LED has entered a stable growth era from full competition, and the performance of listed companies has also shown a steady growth trend. Its good operating performance has attracted the attention of market funds.
