To calculate how much of a latecomer advantage China has after 35 years of unprecedented growth, one needs to look at the gap between its levels of technological and industrial development and those of high-income countries. The best way to see this is by comparing its per capita income, adjusted for purchasing power parity (PPP), with those of developed countries.
要计算中国在经历了35年前所未有的经济增长之后还剩下多少后发优势，我们需要考察期技术和产业发展水平与高收入国家的差距。考察这一差距的最佳办法是比较经购买力平价（PPP）调整的人均收入。人均收入差距越大，后发优势和增长潜力也就越大。
