The informatization and smart city development level in each area of the Yangtze River Economic Belt has made a great progress in 2014，especially the areas where informatization level are relatively low had achieved significant improvement including network infrastructure，information industry，information of enterprise，e-commerce and e-government. On the other hand，the imbalance of informatization level between the eastern and the western region is still very obvious. Meanwhile，the overall regional coordination mechanism of the Yangtze River Economic Belt has not yet started，so in the future，the Yangtze River Economic Belt should set up informatization cooperation mechanism，strengthen sharing of information resources and information facilities，promote information industry corporations.
