The labor cost rises, and the automatic intelligent equipment is imported.

The advance of the industrial 4.0 wave is accompanied by a high rise in labor costs. With the development of the technology, the selling price of the automatic equipment after the localization is realized has a larger reduction space. Compared to the increase in the manual payroll level at a rate of 10-20% per year, the price of automation equipment drops at a rate of 4% per year. In the labor-intensive logistics industry, automatic equipment is introduced to replace manual operation, so that the operation intensity is reduced, and labor cost reduction becomes more urgent. Loading, unloading, transport are the essential link of logistics operation, but because of intensity of labour is big, the recruitment breach is serious.
