Steel and Iron Output Prediction in Hebei Province Based on Circular Economy

摘要

At present, the development of steel and iron industry in Hebei Province faces the restriction of resource, energy, water shortage and environment protection pressure. It is the only way to develop circular economy in order to sustainable development. This paper based on circular economy theory. First, determined the influencing factors of steel and iron output; Second, screened factors by correlation analysis and built a prediction model, at the same time, used the stepwise regression law to optimize the model, and made use of a variety of testing methods to ensure the prediction model scientific and accurate; Finally, used the prediction model to predict the future production reasonably. Modeling method used in this paper has good scalability and can be applied to larger scale analogy.
