钢材是国民经济中应用最广泛的基础材料,钢铁价格的变动对国民经济会产生重要影响。研究钢铁价格的影响因素,可对刚铁价格变动的原因进行深入理解,以期减少钢铁价格波动对国民经济造成的影响。本文以国内综合价格指数为研究对象,选取钢铁价格的各影响因素,运行最小二乘法进行多元回归分析进行实证研究,研究发现国际钢铁综合价格指数、生产者价格指数化指数、铁矿石综合价格指数和钢铁库存是有效变量,其余变量在模型中舍去,实证结果显示国际钢铁价格的上升、铁矿石价格的上升、生产者价格指数的上升以及钢铁库存的减少都会引起钢铁价格的上涨,对钢铁综合价格指数影响程度由大到小排列为生产者价格指数化指数、钢铁库存、铁矿石综合价格指数和国际钢铁综合价格指数。
Steel is the most widely used basic material in the national economy. The changes in steel prices will have a significant impact on the national economy. Studying the factors that influence the price of iron and steel can deeply understand the reasons for the price change of iron and steel, with a view to reducing the impact of steel price fluctuations on the national economy. This article takes the domestic composite price index as the research object, selects various influencing factors of the steel price, conducts the empirical research by using the least squares method and multiple regression analysis, and finds that the international steel integrated price index, the producer price index index, the iron ore comprehensive price Index and steel stocks are effective variables, and the remaining variables are discounted in the model. The empirical results show that the rise of international steel prices, the rise of iron ore prices, the rise of producer price indices and the reduction of steel stocks all will cause the steel prices to rise, The impact on the integrated iron and steel price index from high to low for the producer price index, steel stocks, iron ore composite price index and the international steel price index.
