The mechanism is as old as the hills. You pay for favourable conditions for your business, and unfavourable conditions for your competitors. Australia has a classic history of political figures being given very comfortable jobs in the private sector after they've greased the wheel for their largest donors. This applies to tech, communications, finance, property development and probably every other money making sector.
When contracts are awarded to companies based on lobbying and donations it stymies competition.
The following quote is from the report linked at [1]. It's worth reading the entirety of that report.
"the growing politicisation of public service, exemplified by political appointments to government bodies (Griffiths et al. 2022), may spill over into the contract market. Links between politics, donations, and contracts may negatively impact competition and firm entry".
