Cement is one of the main products of building materials industry. As an important basic raw material for national economic construction, it plays a vital role in the whole building materials industry. The upstream and downstream industries of cement involve mining, clinker , coal, electricity, aggregate, concrete, steel, glass and other building materials and construction and installation industries. Whether as the upstream demand side or as the downstream supply side, the rise and fall of its price always attracts the attention of the market.
In 2022, the cement industry is struggling to move forward in the fog. Epidemic, weather, real estate, capital and so on have become uncertainties affecting the trend of the cement market. Market confidence is low, industry production and demand are weak, cement price trends frequently deviate from market predictions, and shocks are repeated. Elusive. How to accurately predict the trend of cement price and take the lead in the market is particularly important in the current and future market. At the beginning of
2023, the Cement Big Data Research Institute officially launched the "National Cement Price Prediction Data Screen", whose underlying model is a mixed prediction model of multiple regression and ARIMA. The model predicts the cement price of the national P.O42.5 bulk cement in the next four weeks. According to the prediction results of the cement price in the three years from 2020 to 2022, the relative error prediction accuracy in the next week is as high as 99%, and the other three periods are more than 90%. In addition, the trend consistency (price correlation coefficient) of each model is also above 0.7, and the forecast value of the next week is basically controlled within ± 2% of the actual price difference. If the domestic economy returns to normal in the future, the external interference factors such as the epidemic will be reduced, and the prediction accuracy of the model will be further improved. The
national cement price forecast data screen is updated around 18:00 every Friday, which will forecast the cement price on Friday in the next four weeks in turn. The data are visualized in the form of trend charts. The blue solid line represents the actual price, the green dotted line represents the forecast price, and the gray dotted line represents the ± 2% price difference range of the actual price. More prediction models and products will be launched in the future, please pay attention. Cement Big Data Research Institute
