Payment by Results Market Forces Factor upliftを日本語ではどのように表現すればよいでしょうか？

This phrase appears in the following paragraph (page 11 of Costing Industry Sponsored Studies Through the NIHR Networks, http://www.sabp.nhs.uk/aboutus/policies/A-C/clinical-trials/... published by the UK's National Institute for Health Research).

"Direct staff costs (e.g. consultant hourly rate = £68.75), will have 70% overheads and 20% capacity building added. Therefore one hour of medical time calculated using the UKCRN Costing Template will cost £130.63. As all costs also have a Payment by Results Market Forces Factor uplift, as described previously, the maximum consultant hourly rate becomes £163.28 per hour when multiplied by the maximum PbR of 1.25."
