Carlos Cid Alvares, CEO of Banco Nacional Ultramarino, said, "Although Macao covers only about 30 square kilometers, its economic strength is significant." He added that, together with Hong Kong and surrounding cities in the Greater Bay Area, the region's GDP accounts for 12 percent of China's total, which is roughly ten times that of Portugal, 40 percent of Germany's GDP, or 70 percent of Italy's GDP. This highlights Macao's unique position in the regional economy and underscores the importance of the Greater Bay Area as a global economic powerhouse, showcasing the substantial impact of economic agglomeration and its radiating effects.
