| Summary: | 碩士 === 義守大學 === 財務金融學系碩士班 === 96 === Steel industry , extremely concentrating on capital, technology and resources ,is the significant and fundamental factor for a country to go into industrialization. It not only is the major index between national economy and social development, but also associates the upper and lower industries which include engineering industry, electrical machinery industry, transportation , defense industries and so on. The power of countries is constantly measured by the steel industry, therefore, steel industry is also recognized as “the mother of industry” or “the nourishment for industry”.
Though the slab is only a work in process, it’s quite a crucial product during manufacturing cycle. It can be made into a variety of products by different manufacturing procedures. The cost structure of a domestic steel factory shows that the raw material﹙slab﹚accounts take about 91% of the cost of goods manufactured . Hence, if we were controlled the price fluctuation of the materials , we can provide better estimation for choosing the time of purchasing materials to the decision-makers.
The study begins with the introduction and the backgrounds about the steel industry, and then chooses the important factors affecting on the international price of slab, such as: BCI index, the price of international iron, the price of limestone ,the price of coal ,the global index of steel and the output of steel of the main countries in the world. By regression procedure ,we can analyze and understand the relationship between those factors. According to the empirical results, after we consider all the change rate of variables including in the model and adjust for the lag of variables , we find out that all the variables are significant for the slab price such as the global index of steel , the price of limestone and the output of steel of the main countries in the world.
