The market structure of the Taiwanese electric furnace steel dust handling industry is relatively concentrated, with ( Taiwan Steel Union Co., Ltd, TSU ) as the market leader, continuously increasing its market share. However, the volume of dust collection and transportation has been decreasing over the years. At the same time, other domestic competitors in the industry also show a declining trend in dust collection and transportation volume, indicating a confirmed contraction in stainless steel production. Therefore, the production and market share of crude zinc oxide processing plants are influenced by industry conditions and technological advancements, and it is important to continuously monitor relevant data to grasp market trends.
From the perspective of market structure, the market concentration of the top four processors has always maintained a situation where one is large and the other two are small. Therefore, the steel dust treatment industry belongs to an extremely concentrated market structure, and TSU, as the market leader, is almost irreplaceable. According to the industry concentration index and the HHI index, this industry belongs to a high oligopoly market with extremely high market concentration.
A highly concentrated market structure has significant implications for market competition, consumer rights, and industry development. When evaluating market structure and formulating corresponding policies, it is important to closely monitor the industry′s development dynamics to ensure fairness and effectiveness in market competition.
In terms of company behavior, the processing costs of dust handling plants such as TSU and Company KCR are within the market range but relatively low. TSU benefits from its shareholder status in steel mills that provide raw materials, resulting in lower prices. Company KCR, on the other hand, obtains raw materials from other stainless steel mills and sets prices based on market conditions. Dust handling costs are influenced by various factors, including coke prices, international zinc prices, electricity costs, electrode rods, reducing agents, coke, and international nickel prices.
TSU demonstrates stable growth in operational performance, with continuous increases in revenue and profitability. Company KCR has also shown some improvement in operational performance, although relatively lower. The establishment of processing plants not only creates employment opportunities but also helps improve the environment, promote industrial cycles, and make social contributions. |
