Szymon Hołownia made the declaration in a televised speech on Thursday night.
Hołownia, who is the leader of the centre-right Poland 2050 group, said that parliament "must above all serve the people" and help "solve everyday problems," Polish state news agency PAP reported.
Hołownia declared that each parliamentary group would be represented in the chamber's leadership.
The new Speaker also mentioned that he plans to meet with President Andrzej Duda on Friday to discuss cooperation in the legislative process.
Hołownia declared that he would "stress the need to quickly form a new government that will solve the real issues facing the Polish people, such as reducing the costs of living and ensuring national security."
He added that his aim would be to "help improve the quality of debate and the quality of law made by MPs."
Hołownia, a centre-right opposition politician, became lower-house Speaker when Poland's newly elected parliament convened for the first time on Monday.
He was backed by 265 MPs, defeating Elżbieta Witek from the ruling conservative Law and Justice (PiS) party, who won 193 votes.
Four pro-European Union opposition parties secured a combined 248 seats in the Polish lower house following last month's parliamentary election.
On November 10, the four groupings, the liberal Civic Coalition (KO), Hołownia's Poland 2050, the rural-based Polish People's Party (PSL), and the New Left, agreed to form a coalition government.
Hołownia is expected to serve as lower-house Speaker for two years. After that, he will be replaced by Włodzimierz Czarzasty of the New Left, reporters were told.
Polish President Andrzej Duda on Monday named the outgoing Prime Minister Mateusz Morawiecki as prime minister-designate, tasking him with forming a new Cabinet.
Morawiecki has until November 27 to unveil the lineup of his new government.
Morawiecki's ruling conservatives won Poland's October 15 election, but lost their parliamentary majority and look unlikely to stay in power for a third consecutive term.
