基于等维灰色递补方法预测广西人口数量

Population forecasting of the Guangxi region based on the method of recursive compensation by gray numbers of identical dimensions

利用2004～2006年数据采用等维灰色递补动态预测方法对广西2007～2020年人口数量进行了预测。结果显示,到2020年广西人口数量将达到5500万人左右。低增长率高增长量并存是广西今后一段时期人口数量变化的主要特点。

The paper forecasts the population of The Guangxi Zhuang Autonomous Region fi＇om 2007 to 2020, adopting the dynamic forecasting with recursive compensation by gray numbers of identical dimensions through the data from 2004 to 2006.The results reveal that up to the year of 2020, the population of The Guangxi Zhuang Autonomous Region will reach about fifty five million. The main characteristic of population changing is the low growth rate and the high increment during the period of the future.
