The theory of information ecology is a new subject which analyzes the imbalance in supply chain information management by combining the theory of supply chain management, and puts forward corresponding countermeasures from the perspective of information ecosystem balance. In fact, no matter how advanced the information technology is, the premise of its existence is to serve mankind. In society, there is a group of people that can't be ignored - the elderly. When advanced technology no longer serves the elderly, they are frequently labeled as "refugees on the Internet" and "islands of information". In the special time interval of the global COVID-19 epidemic, this situation is getting even worse. Then what is the reason? That's exactly the theme of this paper, including the impact of information ecological imbalance on the willingness of the elderly to learn information technology, and the impact on the use behavior of G2C elderly users. It is hoped that through the discussion of the actual situation of the elderly using G2C under the imbalance of information ecology, more people such as the researchers of G2C, the designers of information products and applications, and the makers of Internet laws and mechanisms can understand the special needs of this group. It is also hoped that they should take into account the special needs of the elderly, provide them with information technology products that are more suitable for their use, and enjoy the convenience that information technology brings to their later life.
