But the long-term economic prospects of the global economy as a whole look gloomy. As societies in many OECD countries age, and catch-up growth in large emerging economies begins to wind down, global GDP growth is expected to fall from its annual average of 3.6% in the 2010-2020 period to an estimated 2.4% in 2050-2060.
但全球经济的总体长期前景相当黯淡。许多经合组织国家社会面临老龄化，而大型新兴经济体的赶超增长开始减速，预计全球GDP年均增长率将从2010—2020年间的3.6%下降至2050—2060年间的2.4%。
