Market Structure, Concentration and Resilient Economic Growth in Lusophone Countries in the Age of AI
Keywords:
Market structure; Concentration; HHI; Ck; Artificial intelligence; Economic resilience; Industrial dynamicsAbstract
This article analyzes market structure, concentration, and industrial dynamics in Mozambique's coal mining sector to assess their implications for economic resilience and new growth models in the era of artificial intelligence. The analysis uses secondary sales data from the main companies operating in the sector to estimate concentration indicators, namely the Herfindahl-Hirschman Index (HHI) and the concentration ratio (Ck). The results reveal a highly concentrated market structure, dominated by a small number of large firms. The analysis of market share stability indicates low mobility among economic agents, suggesting entry barriers and relatively rigid industrial dynamics. Additionally, the article examines the emerging role of artificial intelligence in reshaping markets, highlighting its potential to enhance productive efficiency while also reinforcing market concentration and the market power of technologically advanced firms. In this context, the relationship between market concentration and economic resilience appears to be ambivalent, as it may simultaneously promote stability and limit competition. It is concluded that understanding market structure, combined with analysis of technological transformations, is essential for formulating economic policies and business strategies aimed at sustainable growth in Lusophone countries.
