China's economy is entering a period of transformation, and the innovation and upgrading of manufacturing industry has become an inevitable trend. The core driving force is the accelerating urbanization level and the transformation of economic structure based on the promotion of domestic demand, and the resulting international transfer of industries. In this process, the role of policy can not be underestimated. Under the premise of internal and external conditions, the promotion of policy plays a role of catalyst and combustion promoter for the development of the industry.

The acceleration of urbanization will promote the development of transportation infrastructure, electronic information and new energy industries. As one of the three passive electronic components (resistor, capacitor and inductor), capacitor plays an important role in the electronic component industry. It is an essential basic electronic component in the electronic circuit. The development level of capacitor industry affects the development of China's electronic information industry to a great extent, and it is a national key industry.
