Abstract
Now that society is in the second digital revolution, blockchain technology will be widely used in various fields. From the perspective of blockchain technology application, this paper takes the financial indicators of the input and output of the blockchain concept of China's A-share listed in 2015~2018 as a sample, and introduces the DEA method to analyze its investment efficiency. The results show that the introduction of blockchain technology is shorter and the investment efficiency is declining. Therefore, improving the cost management and controlling the cost of investment will help the investment efficiency of listed companies in the blockchain concept stocks.
