It has a concentration of modern service industries, vibrant market entities, and a diverse range of service, catering, accommodation, wholesale, and retail businesses. As a pilot area for the integrated development of the development zone and subdistricts/towns in Binhai New Area, Xinbei enjoys significant location advantages and industrial strengths.

Over the years, Xinbei has implemented various boutique projects such as the "Social Organization Public Welfare Sharing Program" and the "Happy Dandelion," leading tens of thousands of residents in the area to jointly build, govern, and enjoy the beauty of the new Xinbei.
