The document, which is published by The Mersey Partnership, examines the area's potential for a "globally successful" super port that would build on Liverpool's location, air, road and rail links and maritime skills.
The plans are being discussed by a partnership of public and private sector organisations including Merseytravel and the North West Regional Development Agency.
Mersey Maritime and TMP Members Peel Holdings, Peel Ports and Sefton Metropolitan Borough Council are also involved in the project. TMP is co-ordinating the partnership.
Mersey Partnership chief executive Lorraine Rogers said: "Through developing effective partnerships and working together as a united force for Liverpool City Region, we believe this vision and the economic benefits it can create is well within our reach."
Projects for the super port which are already under way or planned for the future include improving infrastructure through schemes such as the new post-Panamax container terminal on the River Mersey at Seaforth, the proposed new World Cargo Centre, road link and runway extension at Liverpool John Lennon Airport, regeneration of Weston Docks and the 3MG Mersey Multimodal Gateway for road and rail freight handling.
Mersey Maritime chief executive Jim Teasdale added: "Moving this project forward from its concept stage will require significant skills, resource and industry engagement."
