Shanghai’s urban management and law enforcement authorities are taking a digital approach to improve efficiency, officials said yesterday.

A three-tier management system for street-side businesses has been set up, corresponding to different inspection frequencies based on potential hazards given consideration to their business models and operation, the Shanghai Urban Management and Law Enforcement Bureau said.

For businesses tagged “red,” an inspection is conducted at least once every two days.It is once a week for those tagged “yellow” and once a month for “green” businesses.

The tags can be adjusted based on inspection results, complaints from residents, and media exposure.

In March, a citywide inspection covered around 200,000 street-side businesses across the city.

About 32 percent are tagged “red” at present, 6.9 percent down compared with from January and February, and 49.7 percent “yellow,” down 3.7 percent.

Some 18 percent are “green,” up 19.4 percent, signifying significant progress in urban management and law enforcement, officials said.

The authorities in the Pudong New Area are the first to trial the three-color system.

“Fruit shops and express delivery stations top the list of ‘red’ businesses because they lead to more practices that affect the street environment and order,” said YuanXingchao, head of the information direction center of Pudong’s Urban Management and Law Enforcement Bureau.

“Clothing shops and supermarkets are mostly marked ‘yellow’ and go-between housing agencies and financial institutions are mostly ‘green,’” he said.

“The colors are changed in real time and frequent violators or those refusing to rectify irregularities will have their colors upgraded.”

A smart system connecting a comprehensive information platform, sub-platforms of 35 urban management teams, and the law enforcement terminalappsof about 1,800 officials has also been established in Pudong.
