中文摘要:在变量选择的基础上,构建基于Lasso方法和BP神经网络的预测模型,并对我国城乡居民的消费支出进行预测,结果显示:基于Lasso方法和BP神经网络的组合预测精度要明显高于BP神经网络、Lasso方法的预测精度;在2014~2020年,我国农村居民消费增长率有所提升,城镇居民消费增长率减缓,城乡居民消费增长率之间的差距呈下降趋势,但短期内城乡居民消费差距依然难以缓和。

The Study on Prediction of Residents Consumption Expenditure based on Lasso and BP Neural Network
Abstract:On the basis of variable selection, created a multivariate prediction model based on the combination of Lasso method and BP neural network ,and prediction of China's urban and rural residents consumption expenditure. 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.
