[目的/意义] 将知识创新作为因变量引入数字文献信息资源生产价值链中，分析价值链中各主体间相互作用的原理，从而理清当前我国数字文献信息资源保障建设中存在的问题与发展方向。[方法/过程] 借助价值链模型分析数字文献信息资源知识生产的系统结构，并通过Vensim PLE软件进行系统动力学模型仿真，进行仿真分析和敏感性分析。[结果/结论] 社会整体的知识创新对于知识获取成本与知识共享性的敏感度最高，在当前我国数字文献信息资源生产中，出版商赋予高知识附加值但传播效率低，数据商高传播率但知识附加值不足，从而导致成本高且转型困难的局面，为此需要实现文献信息资源保障体系的重构。

[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.
