(Yicai Global) Nov. 10 -- Haikou, on China’s southern island province of Hainan, topped Chinese cities in their ecological environment indexes this year, followed by Kunming, Nanning, Beijing and Guiyang, 21st Century Business Herald reported, citing data from the Academy of Guangdong-Hong Kong-Macao Greater Bay Area

Cities with the lowest rankings include Changsha, Lanzhou, Xi’an, Chengdu, Jinan, Xiamen, Shanghai, Shijiazhuang, Tianjin and Zhengzhou. Many ranked poorly due to high concentrations of PM2.5, particulate matter with a diameter of less than 2.5 micrometers , though Shanghai and Xiamen were let down by large amounts of wastewater discharge per unit area, as both cities have a relatively small land area. The bottom three cities were all up north.

The academy’s research group selected a total of 35 municipalities, deputy provincial-level cities and provincial capitals for their study. Lhasa in Tibet was not selected due to a lack of available data. The group calculated the cities’ business environment index based on their soft environment (25-percent weighting), market environment (20-percent weighting), business costs (15-percent weighting), infrastructure (15-percent weighting), ecology (15-percent weighting) and social services (10-percent weighting). First-tier cities Guangzhou, Beijing, Shenzhen and Shanghai boast substantial business strengths, which helps them to attract talent, resources, investment and technology.

The data used came from the cities’ 2016 data and environmental reports and statistics from the World Bank and local transport bureaus.
