Which city is better in China?

The ranking of the most livable cities in China was officially released.

China ranks as the most livable city, and Fuzhou ranks 10th.

This study * * * selected 50 major cities in China as the evaluation objects, including:

① Provincial capital cities and cities with separate plans (35 cities): Beijing, Tianjin, Shijiazhuang, Taiyuan, Hohhot, Shenyang, Dalian, Changchun, Harbin, Shanghai, Nanjing, Hangzhou, Ningbo, Hefei, Fuzhou, Xiamen, Nanchang, Jinan, Qingdao, Zhengzhou, Wuhan, Changsha, Guangzhou, Shenzhen, Nanning, Haikou and Chongqing. Among these 35 cities, there are 4 municipalities directly under the central government, namely Beijing, Tianjin, Shanghai and Chongqing; Sub-provincial cities (including provincial capitals) 15, namely Shenyang, Dalian, Changchun, Harbin, Nanjing, Hangzhou, Ningbo, Xiamen, Jinan, Qingdao, Wuhan, Guangzhou, Shenzhen, Chengdu and Xi 'an; There are 0/6 provincial capital cities/kloc, namely Shijiazhuang, Taiyuan, Hohhot, Hefei, Fuzhou, Nanchang, Zhengzhou, Changsha, Nanning, Haikou, Guiyang, Kunming, Lanzhou, Xining, Yinchuan and Urumqi.

② Coastal open cities and port cities (9): Qinhuangdao, Lianyungang, Yantai, Weihai, Shantou, Zhanjiang, Zhuhai, Beihai and Nantong.

③ Representative resource-based cities (2): Daqing and Baotou.

④ Cities with special significance (4 cities): Tangshan, Wuxi, Suzhou and Wenzhou.

⑤ Due to the lack of statistical data, Lhasa was not included in the statistical analysis. ⑥ Due to data, China, Hongkong, Taiwan Province Province and Macau are not included in this report. The evaluation results of this project are limited to the comparison between these 50 cities.

3.2 Description of calculation method for urban evaluation

The method of "dimensionless quantification standard treatment, equal weight assignment, step-by-step summary and average calculation" is adopted to calculate the suitable human settlement level of 50 cities in China.

(1) For the positive indicator (the bigger the better), the calculation formula is: evaluation score =[(Xi- minimum) (maximum-minimum)] ×100;

(2) For the inverted index (the smaller the better), the calculation formula is: evaluation score = [(max-XJ) (max-min)] ×100;

(3) For moderate indicators (with critical threshold), the calculation formula is: evaluation score =[|Xt-Xk| (max-min)]× 100. Where Xi is the data of positive indicators (i= 1, 2,3, …, n); Xj is the data of the reverse indicator (j= 1, 2,3, …, n); Max is the maximum value in the indicator series; Min is the minimum value in the exponential series; Data of Xk moderate index (k= 1, 2, 3, …, n); Xt is the critical threshold of exponential series. Xj is the data of the reverse indicator (j= 1, 2,3, …, n); Max is the maximum value in the indicator series; Min is the minimum value in the exponential series; Data of Xk moderate index (k= 1, 2, 3, …, n); Xt is the critical threshold of exponential series. According to the above calculation methods and formulas, the economic development level index (a), economic development potential index (b), social security index (c), ecological environment index (d), quality of life index (e) and convenience index (f) of 50 cities were calculated respectively. Finally, through the average, the city livability index is calculated, that is, the livability index =
