Concentration in productivity, because the domestic large-scale enterprise is not much, small and medium enterprises occupy the main body is given priority to, this makes in the extension of the field to top ten enterprise production concentration is 75.4%, and the chip is much lower field, only 56.4%, display field 45.6% levels. Visible, the more the higher the concentration degree of the domestic front, the downstream products is the enterprise is numerous, yields low concentration. Overall speaking, LED shop lighting industry in China industrial concentration relative is not high, the upstream of the normal but with concentration although many LED high bay lighting enterprises face down into the situation.
In the brand concentration, because domestic well-known brand enterprise is not much, small brand enterprise occupies the main position, this makes the extension field in the top 72.4% of brand concentration, chip field were far lower, only 52.3%, display field 40.6% levels. Visible, with similar capacity concentration, the more the front end of the brands, the higher the concentration, the downstream products is the enterprise is numerous, low brand concentration. Overall speaking, LED shop lighting industry in China brand concentration is not high, low power industry whole, to walk the road of the brand still has a long time.
In the technology competition pattern, extension field is several monopoly enterprises technology, foreign entrants difficult to quickly enter; In the chip manufacturing technology is relatively low barriers, a variety of technologies coexist; In the display manufacturing field because the product application diversity, technology is also diversified, its lowest barriers. Overall speaking, in the technological competition pattern of the extension, chip field clear, display screen technology field is numerous, product variety.
