基于熵权法的天然气供需关系综合评价

Evaluation of the Relationship Between Supply and Demand of Natural Gas Based on Entropy-right Method

针对我国天然气供需关系的研究对保障居民生活和工业生产,以及对我国天然气的发展具有重要意义。运用了熵权法对2008-2012年国内天然气供需关系进行了综合评价。从物质、经济、环境三方面对影响我国天然气供需关系的指标进行了划分;建立了以熵权法为基础的天然气供需关系综合评价模型,以2008-2012年天然气供需关系指标作为数据,分别计算了5年中天然气供需关系综合评价得分,并对其计算结果及其变化规律进行分析与讨论。

Research on the relationship of natural gas supply and demand has the important meaning to residents living and industrial production and development of natural gas in China. In this paper, the entropy method was used to make comprehensive evaluation on the relationship of nature gas supply and demand. the influence indexes were divided from three aspects of material, economics and environment; Comprehensive assessment model of natural gas supply and demand relationship was established based on the entropy weight method with the data of natural gas supply and demand in 2008 to 2012 as relation indexes, comprehensive evaluation of the relationship between supply and demand each year scores of gas were calculated, and the calculating results and the variation were analyzed and discussed.
