摘要
将广东省地区生产总值作为研究对象,基于灰色预测法对1978—2016年数据进行分析,建立GM(1,1)模型.数值仿真结果表明,该模型的拟合效果较好.利用所建立的模型预测2017—2021年广东省地区生产总值,可为了解广东省未来经济发展水平提供一定的参考.
Takes the Guangdong′s gross domestic product as the research object,and analyzes the data from 1978 to 2016 based on the grey prediction method,then establishes the GM(1,1) model.The numerical simulation results show that the fitting effect of the model is good.The gross domestic product of Guangdong Province from 2017 to 2021 is forecasted by using the established model,it can provide a certain reference for understanding the level of future economic development in Guangdong Province.
