基于五力模型的行业竞争程度评价方法
|
Abstract:
行业竞争程度的评价能够帮助企业了解某一行业的总体竞争状况并制定有针对性的竞争策略具有重要意义。本文针对行业竞争程度的评价问题，提出了一个基于五力模型的群体评价方法。在该方法中，首先，构建基于五力模型的行业竞争程度的评价指标体系，其由五个维度及相应的评价指标构成，并考虑维度间和指标间的关联性；然后，运用二元语义表示模型处理和集结专家群体给出的具有语言短语形式的评价指标关联信息和针对行业的评价信息，并运用DEMATEL方法确定评价指标的权重；进一步地，运用二元语义算术平均算子进行行业竞争程度总体评价值的计算。最后，通过一个实例分析说明了本文提出方法的可行性以及潜在的应用价值。
Evaluation of the state of industry competition can help companies indicate the competitive status of an industry. It is of great significance for the enterprises to understand the competitive degree of a certain industry and to formulate competitive tactics. In this paper, a group evaluation method based on the five forces model is proposed to evaluate the state of an industry competition. First, the evaluation index system based on the five forces model is structured, it contains five dimensions as well as various corresponding evaluation indexes, and the correlations among dimensions and indexes are also considered. Then, the 2-tuple linguistic representation model is used to process and aggregate the linguistic correlation information and the linguistic evaluation information with regard to an industry provided by experts. Next, the weights of evaluation indexes are determined using the decision making trial and evaluation laboratory (DEMATEL) method. Furthermore, the overall score of the state of industry competition can be calculated using the 2-tuple linguistic averaging operator. Finally, a case study is given to illustrate the feasibility and the potential application of the method proposed in this paper.
