In the open and shared digital era today, the construction of digital information-based ecological chain platform not only helps to break through the bottlenecks in the construction of talent cultivation system, the strategic development of enterprises and the objective planning of students, but also effectively and powerfully promotes the information-based co-construction, sharing and symbiosis between colleges and enterprises. At the same time, the digital information-based ecological chain platform can help college students communicate with colleges and enterprises in depth, and encourage them to quickly internalize the platform information results, so as to choose their major direction clearly, clarify their future development direction and continuously improve their employment rate. In this work, the theory on ecological chain integration of talent cultivation and campus recruitment was used to build a digital information-based ecological chain platform to solve the problems existing in the current campus recruitment and talent cultivation system. In addition, how to implement and practice the information-based ecological chain platform was also analyzed and expounded. Digital information-based ecological chain platform is an inevitable requirement to realize the development of talent cultivation and campus recruitment. Only in this way, colleges, enterprises and college students with different characteristics can be closely linked up, can cooperate and help each other so as to promote the benign flow and circulation of platform information, truly meet the needs of social development, and provide new ideas for the cooperative construction and development of colleges and enterprises.
