The requirements of the Northern Hub effectively mandated 7 services through Oxford Rd by specifying that services from all "major corridors" served both a single central Manchester station (for which Piccadilly was chosen) and Manchester Airport. These 7 IIRC were Leeds/Huddersfield (2tph), Leeds/Bradford(1tph), Preston/Bolton (1tph), Liverpool (Chat Moss)(1tph), Liverpool(CLC)(1tph) and Chester(1tph) - Sheffield and The South were also major corridors.
The major corridors were indeed chosen on factors heavily biased towards maximising external investment into the North - this as well as obviously being desirable for the area, increases tax revenues in future years and so improves the business case for investment. So yes "attracting businessmen" (Chinese or not) was a prime requirement for the Hub. Passenger numbers (current and potential) were also lesser factors - the TOCs need fare revenue after all. I'm afraid Southport didn't score anywhere highly enough on either count to be a major corridor.
The May 2018 timetable implements all the Hub services, but the 5 extra paths do not appear to have been chosen according any logical requirements, but a mixture of DfT/Local/industry politics, which means that the CLC gets 1 extra service (fair enough given the existence of the Liverpool-Norwich service) and the Preston/Bolton corridor an astonishing 4 extra services. However despite this Southport lost its service, it seems to me because local politicians did not shout loudly enough over the last 5 years compared with industry voices (who wanted to retain Scotland/Cumbria services), TfGM wanting Bolton/Stockport services etc.
