In recent years, with the rapid development of China's LED industry, the scale of China's epitaxial chip industry has also achieved significant growth. From 2006 to 2013, the scale of output value increased by 10 times, with an average annual compound growth rate of more than 30, significantly faster than the international level in the same period. Especially after 2010, with the centralized release of China's epitaxial chip production capacity, the industrial scale expanded rapidly. 2013 China's chip link output value reached 10. 5 billion yuan increase 31. 5. In 2013, with the continuous release of MOCVD capacity, the output of LED chips increased by 61 to 280. 5 billion. Among them, the annual output of GaN chips was 180 billion, an increase of 58. 5. With the accelerated launch of the general lighting market, it is expected that the output scale of the entire chip market will grow rapidly after 2014, and the growth rate will remain around 50.
