中文摘要：

[目的/意义]网络信息生态链的优化以“网络信息生态链要素质量提升”“网络信息生态链运行效率提高”“网络信息生态链输出价值提升”为目标。文章旨在解决在资源、成本有限的情况下,应优先优化哪项网络信息生态链相关要素,从而带动网络信息生态链得到整体高效优化的问题。[方法/过程]基于信息生态理论,采用多目标突变决策方法,建立网络信息生态链优化的多目标决策模型。[结果/结论]给出燕尾型、尖点型、折叠型网络信息生态链优化的多目标决策模型运算方法。以淘宝网为例进行实证分析,结果表明应优先优化“产品价值”要素,使淘宝网信息生态链得到整体优化。[局限]在对所获取的数据进行统一量化方面,有待深入研究。

英文摘要：

[ Purpose/significance] The optimization of network information ecological chain has three objectives： the quality improvement of its basic elements ; the operating efficiency improvement and the output value improvement. This paper aims to solve the problem that when there are limited resources and cost, in order to realize the overall optimization of the network information ecological chain, which elements should be first optimized. [ Method/process ] Based on information ecological theory, with the combination of Multi-objective Catastrophe Strategic Decision method, the paper builds a multi-objective decision model of the optimization of network information ecological chain. [ Result/conclusion ] The paper offers multi-objective decision model operational methods of the optimization of the network information ecological chain, such as swallow tail type, cusp type and folded type. By taking ＂Taobao＂ for empirical analysis, results show that ＂product value＂ should be first optimized to bring overall optimization for network information ecological chain of ＂Taobao＂ . [ Limitations ] It still needs further studies in the aspect of making a unified quantification of the acquired data.
