Shadow Welsh Secretary Owen Smith says the extra £100 million to the Welsh Government doesn't come close to balance previous budget cuts.
Plaid Cymru's Jonathan Edwards says the Chancellor has missed key targets.
The Welsh Government hasn't yet decided whether or not to follow moves set out in the Autumn Statement. In England, business rate rises will be capped at 2%, a relief scheme will run for another year and high street firms will get £1,000 discount. Primary school children will get free meals.
There will be extra money for Wales springing from those spending decisions, but it's up to ministers here what happens with business rates and they haven't decided yet if they'll follow George Osborne's example or not. Similarly there's no decision yet on free school meals for Welsh pupils.
Sources within the Welsh Government acknowledge that its budget will increase by £100m as a result of today's announcements. But they say that if ministers decide to match moves on business rates and free school meals, it'll amount to a budget cut.
Welsh Secretary David Jones tells ITV News the Autumn Statement helps young people while sticking to a "long term plan for sustained growth."
When it comes to extra money being given to the Welsh Government as a result of spending announcements made by the Chancellor, you might be confused to see two figures being used. Some are saying the total is £233m over the next two years, others are saying £100m.
UK Government sources say that the increases do add up to the higher figure but that the Welsh Government is right to say cuts and other changes bring the real total down. Chief amongst these is that the Welsh Government doesn't get extra funds (known as consequentials) related to business rates.
Both governments believe£100m is more accurate and that amounts to virtually no change on a £15bn total budget. UK Government sources say that's a good result for Wales; Welsh Government sources say that after a real terms cut of £1.7bn since 2010 difficult decisions will still have to be made.
George Osborne told MPs that growth forecasts are "significantly up" in the largest improvement at any Budget or Autumn Statement for 14 years, with UK growing faster than any other major economy.
George Osborne has said he was seeking "a responsible recovery to allow the Government to live within its means".
He adds that the Government "held our nerve" while critics were "proved comprehensively wrong".
George Osborne says employment is expected to rise by 400,000 in 2013. Unemployment is forecast to fall from 7.6% this year to 7% in 2015 and 5.6% by 2018.
The Office for Budget Responsibility forecasts that private businesses will create 3.1 million more jobs by 2019, more than offsetting reductions in public sector workforce.
Local authorities here in Wales will be able to borrow money for building projects at cheaper rates. According to the Wales Office, councils will be given access to £150m of 'project rate borrowing' over the next two years 'to support priority infrastructure projects in Wales.'
