可变模糊集理论综合评价中,针对各指标之间信息重叠和指标权重主观设定的问题,应用主成分分析求解相应指标的权重,同时降低可变模糊综合评价的维度。文章综合评价了云南2005~2009年低碳经济发展现状,结果相对于仅可变模糊集理论评价结果更接近实际,主成分-可变模糊分析为区域低碳经济发展状况综合评价提供了一种可行的方法。
In the comprehensive evaluation of the variable fuzzy set theory, the principal component analysis is used to solve the weight of the corresponding indicators and reduce the dimensions of the variable fuzzy comprehensive evaluation, in view of the overlapping of information and the subjective setting of the index weights. The article comprehensively evaluates the current situation of low-carbon economy in Yunnan from 2005 to 2009, and the result is more realistic than the result of only variable fuzzy set theory. The principal component-variable fuzzy analysis provides a comprehensive evaluation of the development of low-carbon economy in the region Feasible method.
