Who drives the green shift? EV and battery policymaking and systemic marginalisation of auto suppliers in South Korea

• Big business’ industrial policymaking for EV and battery marginalised auto suppliers in south korea. • Big business elites systematically monopolise information in the hierarchical production structure through subcontracts. • The vertical hierarchy of information significantly limits suppliers’ access, especially to negative information. • Big business’ monopoly of information shapes their structural power, leading to a monopoly of channels to industrial policymaking. The swift global transition to electric vehicles (EV) and batteries in the automotive industry highlights the nature of governments’ efforts towards a green economy, marking a transition from environmental regulations to industrial policies. This shift has led to renewed interest in industrial policies, especially in East Asian developmental states, like South Korea. The EV and battery industries in South Korea have grown rapidly along with the government's efforts to mobilise the entire economy through aggressive green industrial policy, particularly during the Lee Myung-bak administration (2008–2012). Big Korean automobile and electronics manufacturers have participated directly in setting the country's industrial agenda, leading the green industrial policy with their business interests. However, the process of EV and battery policymaking also marginalized auto suppliers in the existing manufacturing sector from agenda setting. Focusing on business’ structural power, this paper explains how big business elites systematically alienate small and medium-sized suppliers from the new growth policy thanks to their strong information monopoly in the hierarchical structure of production in the automobile industry and EV policies in South Korea.
