钢铁工业是国民经济中最重要的基础原材料产业和重要支撑产业。本文根据我国钢铁产量及其影响因素的时间序列数据,利用计量经济模型,分析我国钢铁产量与影响因素之间的关系,并通过模型对钢铁产量进行预测。结果表明,粗钢产量和固定资产投资对我国钢铁产量有显著的影响,并且存在协整关系。
The steel industry is the most important basic raw material industry and an important supporting industry in the national economy. Based on the time-series data of China’s iron and steel output and its influencing factors, this paper analyzes the relationship between iron and steel output and its influencing factors in China using econometric model and predicts the steel output through the model. The results show that crude steel output and fixed asset investment have a significant impact on China’s steel output, and there is a cointegration relationship.
