| dc.description.abstract | After the outbreak of the COVID-19 pandemic in 2019, operations around the world came to a halt, and the escalation of conflicts in the Middle East and Ukraine led to a surge in imported raw materials. In the automotive industry, metal raw materials account for a relatively large proportion of the production cost. This study aims to investigate the impact of raw materials on the operation of the Taiwanese automotive industry.
The study focuses on eight listed companies, including Yulon Motors, China Motor, Yulon Nissan, Hotai Motor, Sanyang, Jui Li Enterprise, Tong Yang Industry, and Gordon Auto Body Parts. Quarterly data on their operating income and operating costs from Q3 2008 to Q3 2022 were collected as research data, and common metal raw materials and crude oil in automotive production, such as copper, aluminum, iron, zinc, lead, tin, nickel, silver, gold, and crude oil, were chosen as research variables based on their futures prices in the market. Correlation analysis and simple regression analysis were conducted to explore the correlation. The empirical results showed that only Yulon Nissan and Sanyang had a significant impact on their operating income and operating costs, while China Motor was only affected by operating income, and the impact on operating costs was not significant. | en_US |
