It evaluated their investment competitiveness based on aspects such as government service, investment vitality, infrastructure construction and ecological conservation.

Cixi, a county-level city in Ningbo, was ranked second on the list, a spot higher than the previous year, while the county-level city of Yuyao, Xiangshan county and Ninghai county came in 9th, 37th and 48th respectively.

The listing of all of the four county-level areas under Ningbo's jurisdictions reflects the city's rising investment competitiveness and continuous optimization in business environment, according to the report.
