Abdullah told parliament's opening session that he will press ahead with plans to amend election laws the opposition says favour pro-palace candidates and overhaul a public sector widely seen as rife with corruption and nepotism.
The king called the reforms a "white revolution" a term royal aides say signifies a peaceful change rather than one of turmoil like those brought by the Arab Spring, which saw four regional leaders deposed in uprisings.
"Jordan is continuing its quest to develop a regional reform model that is home-grown and based on a clear roadmap with specific reform milestones," the king said.
But the opposition met the king's speech, marking the start of parliament's winter session, with skepticism.

"The king is only buying time," said Mohammad Miteb, 19, an accounting sophomore and part of a pro-democracy youth movement. "We're sitting on a powder keg that will soon ignite from sparks, be it from domestic reasons or regional turbulences."
Yet Jordan so far has weathered nearly three years of street protests calling for a wider public say in politics. Abdullah is a close friend of the US and the country relies on donations from the US and oil-rich Gulf Arabs to keep its fragile economy afloat.
It is saddled by a multi-billion-dollar foreign debt, a record USD 2 billion budget deficit, high inflation and a rising energy bill.
So far, Abdullah largely has maintained control, partly by relinquishing some of his powers to parliament and amending the country's 60-year-old constitution.
