China's electronic components production has accounted for nearly 39% of the world. Production in the world's first products are: capacitors, resistors, electro-acoustic devices, magnetic materials, piezoelectric quartz crystals, micro-special motors, electronic transformers, printed circuit boards.
Along with the expansion of China's electronic information industry, the Pearl River Delta, the Yangtze River deltas, the Bohai Bay Area, some central and western regions of the four electronic information industry bases were initially formed. These areas of electronic information enterprises concentrated, the industry chain is more complete, with a considerable scale and supporting capacity.
There are some main problems in China's electronic materials and components industry: the surplus of medium and low-grade products, the main dependence of high-end products on imports, the lack of core technology, the low profit of products, the small size of enterprises and insufficient investment in technology development.
