The paper selected the relevant data of 302 listed companies in information transmission, software and information technology services from 2014 to 2018 in China, used principal component analysis method to analyze the investment value, obtained the ranking of investment value, and compared it with the market performance to determine the investment strategy. Faced with the increasingly mature development of China's information service industry, how to correctly measure enterprise value and judge investment opportunities has become the key to the success or failure of many investors. Therefore, it is of great practical significance to analyze the investment value of listed companies in China's information service industry.
