Almost one-third of Chinese cities are shrinking, but urban planners told to keep building

Satellite imagery monitored the intensity of night lights in more than 3,300 cities and towns between 2013 and 2016

In 28 per cent of cases, the intensity of lights had dimmed, but urban planners are still assuming China’s urbanisation will continue, research shows

China was already facing huge demographic and economic issues. However, a new study of satellite imagery shows that many of its towns and cities are shrinking, with experts warning that it could exacerbate the government’s problems. Photo: Simon Song

The perception that China’s urbanisation is still in full swing is untrue for nearly one-third of Chinese cities, whose populations are shrinking, according to new findings by a Chinese university.

A research team from Tsinghua University used satellite imagery to monitor the intensity of night lights in more than 3,300 cities and towns between 2013 and 2016. In 28 per cent of cases, the lights had dimmed.

China now has 938 shrinking cities, according to Long Ying, an urban planning expert at China’s Tsinghua University, who founded and led the research group, Beijing City Lab. This is more than any other nation on Earth.

The findings are indicative of declining populations and economic activity across almost one-third of the cities monitored, at a time when official economic data also shows that China is facing significant economic and demographic challenges.

Furthermore, the problem is getting worse. Between 2000 and 2012, previous analysis showed that China had fewer shrinking cities than France, Germany, the UK and the US.
