China's laser industry is concentrated in four regions. Wuhan Optics Valley is a large-scale optoelectronic industry cluster center in China, gathering more than 200 well-known domestic laser enterprises, with a complete laser industry chain, and many domestic experts and technical personnel in the laser field. Wuhan Optics Valley has a professional and large-scale national base of industry, university and research, occupying a leading position in laser-related technology in China.

The Pearl River Delta region is another major gathering center of China's laser industry. Related industries are mainly distributed in Shenzhen, Guangzhou, Dongguan, and Foshan. The focus of the Pearl River Delta laser industry cluster is in Shenzhen. Shenzhen has many well-known enterprises in the industry, involving a wide range of laser applications. In terms of market-oriented operation, Shenzhen has an unmatched advantage in Central China. In 2014, the output value of the laser industry in Shenzhen has surpassed that of Wuhan, becoming the first city in the output value of the laser industry. The export volume of the laser industry in the Pearl River Delta region accounts for more than 30% of the national export of laser products.

The Yangtze River Delta region is one of the main clusters of my country's laser industry. The laser industry chain has been perfected. The Yangtze River Delta laser industry is mainly distributed in Shanghai, Nanjing, Wenzhou, Suzhou, Ningbo and other places. It has many laser components, lasers and laser application equipment manufacturers.

The Bohai Rim region is another important laser industry after the formation of central China and the Pearl River Delta. The laser industry in the Bohai Rim region has strong technology research and development capabilities. The market represented by Beijing has gathered a large number of IT and communications industry-related companies, and there is a strong demand for laser products. The booming market demand has driven the development of the laser industry in this region. In general, laser enterprises in the Bohai Rim region are mainly concentrated in Beijing, Tianjin, Shenyang, Dalian and other cities.
