Small and medium-sized enterprises are difficult to survive. For the bankruptcy of these LED small and medium-sized companies, people who have been working hard in the LED industry for a long time are not surprised. Since March this year, the LED market has started to pick up. Many enterprises said that the order volume has increased significantly and the sales volume has increased. It is predicted that the outbreak period of LED has come. Under this optimistic expectation, many LED companies began to increase production and expansion. In this context, production capacity is completely overcapacity, and some companies have completely overdrawn the market in the second half of the year. The reporter looked up relevant industrial and commercial data and found that the registered capital of Shifang Optoelectronics, which has just stopped production, is only 1 million yuan. In the LED industry, it can only be regarded as a small and medium-sized enterprise. From the perspective of LED listed companies that have released the 2013 report, although many companies' profits have declined to varying degrees, these large companies have basically maintained growth in operating income compared with the same period last year. For example, Lehman's revenue increased by 7. 5%. 06, Lianjian Optoelectronics revenue increased by 12. 91, Zhou Ming technology revenue growth 33. 89, dry light photoelectric revenue growth 14. 96, jufei Optoelectronics revenue growth 52. 54. With the increasing competition, the LED market has entered a stage of polarization. Large enterprises are getting bigger and bigger, while the survival of small and medium-sized enterprises is increasingly difficult.
