[Purpose/Significance] Knowledge innovation is introduced into the production value chain of digital document information resources as a dependent variable, and the principle of interaction among various subjects in the value chain is analyzed, so as to clarify the existing problems and development direction in the guarantee construction of digital document information resources in China.[Method/Process] The system structure of knowledge production of digital literature information resources was analyzed with the help of value chain model, and the system dynamics model was simulated with Vensim PLE software for simulation analysis and sensitivity analysis.[Result/Conclusion] The knowledge innovation of society as a whole is most sensitive to the cost of knowledge acquisition and knowledge sharing. However, in the current production of digital literature information resources in China, publishers give high knowledge added value, but the communication efficiency is low, data merchants have high communication rate, but the knowledge added value is insufficient, resulting in high cost and difficult transformation. Therefore, it is necessary to realize the reconstruction of document information resource guarantee system.
