I hear that in the business world, opposition to abandoning the bill submission is intensifying.
Literal
Business-world [at-では], bill-submission abandonment [to-に] opposition [object-を] is-strengthening-[continuous-ている] [hearsay-そうだ].
~そうだ at the end is the hearsay evidential ('I hear that, it's reported that') — distinct from the appearance-~そう. When used sentence-finally with plain-form verbs, it marks information from an external source. 財界 ('business/financial world') is the collective term for business leadership. 反発 ('opposition, pushback, rebound') is used both literally (physical recoil) and figuratively (ideological opposition).
