摘要
论述了适用于居民生活用气量指标的数理统计学模型和计量经济学模型的理论基础、样本构成、建模过程以及各自的优点及存在的问题,提出应将数理统计学模型与计量经济学模型相结合,进行居民生活用气量指标的现状值评估、弹性分析、未来发展趋势预测。
The theoretical base, sample make-up, modeling processes, advantage and disadvantage of mathematical statistics model and econometrics model suitable for domestic gas consumption index are described. It is pointed out that the mathematical statistics model and the econometrics model should be combined to estimate the present value of domestic gas consumption index, analyze the elasticity and forecast the future development trend.
