基于熵权-灰色理论的高速铁路产业链关联分析——以四川省为例

High-speed Railway Industry Association Analysis Based on Entropy-grey Theory: Taking Sichuan Province as an example

高速铁路的迅速发展,给地区带来了极大的经济效益。依照四川省高速铁路产业的发展现状,虽然取得了一定的成果,但依然不具备进行有效的市场竞争。文章分析当前四川省高速铁路发展现状,运用熵权法对发展相关的指标赋权,然后通过灰色关联分析的关联系数计算,找出高速铁路上下游产业链中与其发展关联度高的产业,分别是建筑业、物流业、房地产业、运输设备制造业、通信业、住宿餐饮业和金融业,而与机械装备制造业、商贸流通业和高新技术产业的关联系数较低。通过产业关联度分析,以期为产业发展提供决策支持。

The rapid development of high-speed railway has brought great economic benefits to the region. In accordance with the current development of high-speed railway industry in Sichuan, although some achievements have been made, it still does not have effective market competition. This paper analyzes the present situation of the development of high-speed railway in Sichuan Province, empowers the developmentrelated indicators by using the entropy method, and then calculates the correlation coefficient of gray relational analysis to find the industries with high correlations along the development of the upstream and downstream high-speed railway lines. It has a low correlation coefficient with machinery and equipment manufacturing industry, commerce and trade circulation industry and high-tech industry in construction industry, logistics industry, real estate industry, transportation equipment manufacturing industry, communication industry, catering industry and financial industry.
