With the continuous upgrading of communication technology, human beings have entered the 5G era and the demand for internet devices has become more robust.The development of RF filters as an important part of intelligent devices has ushered in new opportunities. Based on the SCP (structure-behavior-performance) model of industrial organization theory, the current situation of China's RF filter industry development is analyzed and it is found that China's RF filter market is developing rapidly, but mainly produces low-end products.The innovation ability of enterprises is insufficient, and the distribution of enterprises shows the characteristics of small and scattered.Compared with the international market, in terms of market concentration, there is a large gap in terms of market concentration, modular product supply capability, and technology accumulation. It is recommended to improve the market performance of the RF filter industry by improving the filter production yield, actively promoting the cooperation between industry, academia and research, promoting the development of modularization in China's RF industry, and collaborative development among enterprises.
