However, analysts said the barbecue business alone is not sufficient to realize high-quality development in old industrial cities.

Zhou Mingqi, chief analyst at Jingjian Thinktank, a tourism marketing consulting company, was quoted by Caijing magazine as saying, "Barbecue can drive catering, hotels and tourism, but it cannot create bigger economic profits.

"It is impossible for old industrial cities to achieve quick success and instant benefits if they want to succeed in transformation. They still need to set up universities and train talent to drive urban innovation and development."

Ding, from Xiamen University, said such a transformation has been achieved in the city of Pittsburgh in Pennsylvania, United States.

Once known as an industrial hub focused on steel production, Pittsburgh has successfully transitioned into a diversified economy driven by technology, education, healthcare and research.

In Zibo, with the barbecue trend showcasing local hospitality, it will be easier for the city to attract more talent.

Local media reports said officials in Zibo, including Ma, the Party secretary, have visited universities in the past two months to woo graduates.

"Once you have talent, you obtain the power of innovation, which will unleash new development momentum," Ding said.
