The prediction results showed that:the combination of Lasso method and BP neural network prediction accuracy is higher than that of the BP neural network,the Lasso method,the results also showed that in 2014-2020 years, the growth rate of rural residents consumption has improved,the consumption of urban residents increased slowly, the gap between urban and rural consumption rate showed a downward trend,but the gap between urban and rural consumption is still difficult to ease in the short term. %K 消费 Lasso方法 BP神经网络 预测< %K br> %K consumption Lasso method BP neural network prediction %U http://hdxbcjb.cnjournals.net/ch/reader/view_abstract.aspx?file_no=20160119&flag=1
