Abstract: The energy transition significantly impacts key metal markets through various shocks. Using supply, demand, and price data for key metals such as aluminum, copper, cobalt, and nickel in China from 2018 to 2025, this paper employs the TVP-SVAR-SV and GARCH models to categorize energy transition shocks into demand, supply, risk, technology, and policy. It systematically examines their dynamic effects on the metal market. The results show that: (1) Cobalt prices respond most strongly to demand shocks (peak 0.52); (2) Supply disruptions cause cobalt prices to reach extremes of 2.56 worldwide; (3) Geopolitical risks increase volatility to 0.853; (4) Technological shocks have a significant short-term impact on cobalt prices, while nickel prices tend to rise gradually over the long term; and (5) Indonesia's nickel export ban leads to a short-term nickel price change of 0.105. The study recommends enhancing supply chain resilience, promoting technological innovation, and strengthening international cooperation to manage market fluctuations.
