【Abstract】 The apparent demand for crude steel in China is one of the important indicators to measure the market size and development trend of the steel industry.Therefore,accurately predicting the apparent demand for crude steel in China is of great significance for steel companies and government.This article aims to study the problem of predicting the apparent demand for crude steel in China.By analyzing historical data of the Chinese crude steel market,combining macroeconomic factors,industry characteristics,and demand data from other countries internationally,a prediction model based on multitask LSTM is established.By comparing the predictive effects of using linear model schemes,the optimal scheme was obtained.This study has certain reference value for understanding the development trend of China ’s crude steel market and formulating relevant policies,the prediction model and scheme proposed in this article can also provide reference and reference for demand forecasting in other industries.更多还原
