Compared with the overall loss of the industry in 2012, the current LED industry is beginning to see a rebound in prosperity. From the perspective of the industrial chain, the strong demand for LED downstream has begun to be transmitted to the midstream packaging and upstream chip, materials and other manufacturers, and promote the profitability of related enterprises. As Fang Guoxin's net profit increased by 93, in addition, China microelectronics and Zhongfa technology both achieved profitability last year. Some companies attributed their performance growth mainly to the recovery of the industry. Hongli Optoelectronics believes that the market demand for LED lighting in 2013 is good, effectively releasing the company's production capacity, and the company has maintained stable growth in its main business. Jufei Optoelectronics also believes that the company has seized the opportunity of the recovery of the LED industry last year. In addition, the continuous support policies in the domestic LED field last year, the decline in the price of LED lighting products and the further restriction in the use of incandescent lamps have also contributed, and Ruifeng Optoelectronics believes so. Despite this, there are still some companies with poor performance. Among them, the profit decline is more than the benefit, up to 687. 48, followed by Dehao Runda, Nanda Optoelectronics, Huacan Optoelectronics, net profit fell 94. 22, 89. 95, 79. 3. Further analysis found that most of the loss-making enterprises were not due to the decline in LED business performance, but for another reason. Shiyida said that the main reason was the sharp deterioration of the company's EMS business operation, which led to a large loss; Maoshuo power, whose net profit fell 40%, was due to the company's relocation of the office and the increase in labor costs caused by the increase in Shenzhen's low company standards. Huacan optoelectronics and Nanda Optoelectronics mainly lost too much in the first half of the year. In the second half of the year, even if the market demand accelerates, it is difficult to make up for its losses. In this context, listed companies are interested in increasing investment. Oto Electronics said bluntly when receiving research from the organization that the LED lighting business has a large market space and the company will increase investment, which will also become a new growth point for the company's performance. Wanrun technology said that the company will focus on expanding the LED lighting market and products this year, and accelerate the development of new technologies and materials for LED packaging and lighting. Jufei optoelectronics and Hongli Optoelectronics said that 2014 will expand production in light of market conditions.
