During 2001-2010, Chinese electric light source industry witnessed rapid growth with the maximized expansion of industrial scale. In 2010, the annual output of electric light source in China approximated 18.7 billion, and the total output value surpassed RMB72 billion.
The total assets of the industry reached RMB48.3 billion in 2010, up 28% against 2009. The fast expansion of the industrial scale lied in the growing scale of original enterprises as well as the successive surge of peripheral enterprises. In 2010, the number of electric light source enterprises in China registered 931, an increase of 16% from 2009.
Chinese electric light source enterprises have undergone great changes in recent years. Enterprises in such places as the northeast, northwest, and southwest regions have gradually shrunken, and the quantity of provinces without electric light source manufacturers has exceeded 10 from the former three provinces of Tibet, Hainan, and Ningxia. After integration, electric light source industry nowadays is basically centralized in Pearl River Delta and Yangtze River Delta which become the major regional bases of electric light source industry around the globe.
Such coastal provinces and cities as Guangdong, Jiangsu, Shanghai, Zhejiang, and Fujian have been turned into major production areas and shaped certain characteristic regions.
