The Paris Region economy has gradually shifted from industry to high-value-added service industries (finance, IT services, etc.) and high-tech manufacturing (electronics, optics, aerospace, etc.). The Paris region's most intense economic activity through the central Hauts-de-Seine department and suburban La Défense business district places Paris' economic centre to the west of the city, in a triangle between the Opéra Garnier, La Défense and the Val de Seine. While the Paris economy is dominated by services, and employment in manufacturing sector has declined sharply, the region remains an important manufacturing centre, particularly for aeronautics, automobiles, and "eco" industries.
