The pressure to get China back to work after the coronavirus shutdown is resurrecting an old temptation: doctoring data so it shows senior officials what they want to see.  This phenomenon is playing out in Zhejiang province, an industrial hub on the east coast, in the form of electricity usage. At least three cities there have given local factories targets to hit for power consumption because they’re using the data to show a resurgence in production, according to people familiar with the matter. That’s prompted some businesses to run machinery even as their plants remain empty, the people said.

On Saturday, a newspaper in one of Zhejiang’s cities appeared to take aim at the practice. The Taizhou Daily published a front-page commentary criticizing local officials for narrowly focusing on power usage, arguing that hitting the targets won’t ensure economic growth. By Sunday, a link to the article on the paper’s website was no longer working.

China’s official manufacturing purchasing managers’ index plunged to a record low 35.7 in February, underscoring how crucial it is for the economy to get back on track as soon as possible. The Covid-19 outbreak has pummeled both consumption and production, putting millions of companies in peril. But if pressure for results from top leaders creates a distorted view of the economy, the risk of policy missteps by Beijing will rise as well.

“It means that even the more tangential barometers being used by economists and investors alike will be rendered inaccurate, and ultimately unreliable,” said Vishnu Varathan, head of economics and strategy at Mizuho Bank Ltd. in Singapore. “And so looking for the black cat in the dark room will be an on-going endeavor.”

While it’s unclear how wide the problem of doctored data is in China, there are signs that electricity usage has become a focus for more than Zhejiang. The official Xinhua News Agency last week published a story about production resuming in Guangdong, China’s largest provincial economy, using power consumption as the main evidence to show how quickly things were getting back to normal.
