The End of Poverty in China?

Over the last 35 years, China has lifted more than 800 million people out of poverty, and is now committed to doing the same for the remaining 45 million living in rural poverty by 2020. But that will be more difficult and costly than ever, and even when it's done, China will face a growing number of urban poor.

BEIJING – One of the most cited statistics about China may well be the number of Chinese who have been lifted out of poverty over the last 35 years. At over 800 million, it is a huge number – and an extraordinary feat. Indeed, no other country has achieved such a level of poverty reduction in such a short period. But what about the millions of Chinese who have remained behind?

China’s government is committed to finishing the task, with the aim of reducing rural poverty essentially to zero by 2020. The authorities first made the pledge at the United Nations in 2015, and have reiterated it in subsequent official settings. But fulfilling that promise – which would now entail improving the wellbeing of about 45 million people, roughly equivalent to Sudan’s entire population – will carry significant costs.

Poverty reduction, like so many important endeavors, is subject to the law of diminishing returns: the more you do something, the less productive your efforts become. Think of winding a watch: the more you wind, the more resistance builds up in the mainspring, and the more energy it takes to move the stem the same distance.
