运用现代多元统计技术——偏最小二乘回归PLS,在各影响因素存在多重共线性和样本数据短缺条件下进行了定量分析。本文不仅给出各影响因素对湖南电力消费的重要度指标图,而且确定这些影响因素与湖南电力消费需求之间的定量关系,为湖南电力市场分析提供了理论依据。 Using modern multivariate statistical technique, PLS regression, the quantitative analysis was carried out under the condition of multiple collinearity and shortage of sample data. This paper not only gives an index of the importance of each influencing factor to Hunan’s electricity consumption, but also determines the quantitative relationship between these influencing factors and Hunan’s electricity consumption demand, which provides a theoretical basis for the Hunan electricity market analysis.
