摘要:

工业增加值是衡量实体经济运行状况的重要指标,为充分挖掘电力数据在宏观经济现时预测中的价值,服务于政府政策制定和经济社会发展,以电力数据和传统统计数据为基础,采用Bagging和Boosting等算法对工业增加值进行了现时预测。结果表明:第一,传统统计数据可以显著提升ARIMA模型的预测效果;第二,电力数据的预测效果取决于电力指标的选择,选择恰当的电力指标有助于更及时、准确地预测工业增加值;第三,电力数据信息对当期工业增加值的预测能力可能会低于对未来期工业增加值的预测能力,这意味着电力数据更适用于超前的预测。

关键词: 工业增加值, 现时预测, 电力数据

Abstract:

Industrial added value is an important indicator to measure the operation of the real economy.In order to fully mine the value of power data in the current macroeconomic nowcasting, so as to serve the government policy making, the Bagging and Boosting algorithms in machine learning were applied to nowcast industrial added value based on electric power data as well as traditional statistical data.Firstly, traditional statistical data can significantly improve the forecasting effect of the ARIMA model.Secondly, the nowcasting ability of electric power data depends on the selection of electric power indicators, and the proper electric power index is helpful to predict industrial added value more timely and accurately.Thirdly, the prediction ability of electric power data to the industrial added value in the current period may be lower than that in the future, which means the power data is more likely to be used to predict ahead of time.

Key words: industrial added value, nowcasting, electric power data
