According to the prospect database data, in 2017 1-4 months, China's electronic components production totaled 12479 billion, an increase of 7.3% over the same period last year. The value of export delivery increased by 12.4% over the same period last year, up 11.3% in April. The production of electronic components continues to be stable and good.
