Brief comments of the researcher:
At present, the company's business is mainly concentrated in Beijing and Hong Kong. Yiyajie Beijing, a wholly owned subsidiary, is the only company that provides services for the establishment, access and maintenance of Beijing Metro ACC system. Beijing is also the focus of the company's future business development. According to Beijing's 12th five-year Plan, 12 new lines will be opened in 2014 and 2015. In addition, Beijing's 13th five-year Plan is also under preparation, and subway mileage is expected to increase from 660km in 2015 to 1000 km in 2020, so the company's business is more secure in the short term. It is recommended to keep an eye on the company.
