为了研究我国煤炭消费分布及影响因素,运用分位回归和普通最小二乘回归方法,对我国煤炭消费的影响因素进行了分析和对比.结果表明:分位回归与OLS存在较大的差异.其中,分位回归提供了各影响因素在不同分位数上对煤炭消费的影响,分位回归在不同分位点的对比可以得出比OLS相对具有价值的结论.
In order to study the distribution and influencing factors of coal consumption in our country, the influencing factors of coal consumption in China are analyzed and compared by using the method of quantile regression and ordinary least squares regression.The results show that there is a big difference between quantile regression and OLS , Quantile regression provides the impact of various factors on coal consumption in different quantiles. The comparison of quantile regression at different sub-sites can be concluded that it is relatively more valuable than OLS.
