The new industry-based town is an innovative urban development mode with human-orientation as the core, industrial development as the cornerstone and "integration of industry and city" as the signature in the context of novel urbanization, which serves as the power house to drive transformation and upgrading of local industries.

In the meanwhile, in combination with typical cases, this paper organizes and analyzes the innovative modes of how public art manages to empower composite development of industry and culture from the aspects of project type, carrier form, operation mechanism, communication efficiency, etc.
