近年来,西安市经济迅速发展,年均GDP增速保持在11%以上。同时,全市用电量年均增速保持在7%以上,用电量与GDP均保持较高的增长速度。为考察西安市电力与经济发展之间的关系,本文利用Granger因果关系检验方法,分析全市GDP总量及各产业产值对用电量的影响。分析结果表明,西安市的GDP的增长对用电量的影响较大,影响贡献率为52.48%,即GDP每增加1%,用电量就相应增加0.5248%。
近年來,西安市經濟迅速髮展,年均GDP增速保持在11%以上。同時,全市用電量年均增速保持在7%以上,用電量與GDP均保持較高的增長速度。為攷察西安市電力與經濟髮展之間的關繫,本文利用Granger因果關繫檢驗方法,分析全市GDP總量及各產業產值對用電量的影響。分析結果錶明,西安市的GDP的增長對用電量的影響較大,影響貢獻率為52.48%,即GDP每增加1%,用電量就相應增加0.5248%。

In recent years, the rapid development of Xi'an's economy, the average annual GDP growth rate remained at more than 11%. At the same time, the city's average annual growth rate of 7% or more, the use of electricity and GDP have maintained a high growth rate. In order to investigate the relationship between power and economic development in Xi'an City, this paper analyzes the influence of the total GDP and industrial output value on the power consumption by using Granger causality test method. The analysis results show that the growth of GDP in Xi'an has a great impact on the power consumption, and the contribution rate is 52.48%, that is, the GDP increases by 0.5248%.
