Abstract
This article analyzes the process of structural transformation within the Brazilian private health services market since the 2000s, with emphasis on the growing participation of financial funds and foreign capital in the process of expansion and consolidation of the sector. The analysis of the movement of foreign capital into health services and plans in Brazil was developed from the construction of a database with a total of 297 equity operations involving companies with activities in health services, including companies operating health plans and insurance and companies administering health benefits. The analysis of these operations shows that the influx of foreign capital was fundamental to enable the centralization of capital in certain companies and catalyze the process of concentration and structural transformation of the health services sector over the last two decades. We concluded that the intensification of the intercapitalist dispute within the health services market led to the emergence of large corporations and new business models, with special emphasis on the emergence of verticalized care networks (operation of plans, hospital services, outpatient services, diagnosis and treatment, and primary care).
