Mateusz Morawiecki made the remark in an interview with public broadcaster TVP Info on Monday night.
Earlier in the day, Morawiecki's new Cabinet was sworn in before President Andrzej Duda at a ceremony in the presidential palace in Warsaw.
The prime minister told TVP Info that his new government would represent "a coalition for Poland" that "unites and gives hope to the people."
Morawiecki, head of government since 2017, said that under the Law and Justice party, Poland was "one of the fastest-growing countries" and "the proportion of public debt to GDP has fallen by over 3 percentage points," Polish state news agency PAP reported.
He added that Poland's foreign debt "has been reduced significantly in the last eight years, from 66 percent to over 30 percent."
The prime minister said that Poland's economy "has become more productive and competitive," which "has raised the salaries of the Polish people."
Earlier on Monday, Morawiecki posted a video message on the X social media platform, outlining "the track record of the eight years of the Law and Justice government," the PAP news agency reported.
He said publications by international media outlets such as the Financial Times and Business Insider highlighted Poland's "lowest-ever unemployment, fastest GDP growth in the European Union and record export figures."
Poland appoints new government
After Monday's swearing-in ceremony, Morawiecki has 14 days to win a vote of confidence for his new Cabinet in parliament.
Poland's lower-house Speaker Szymon Hołownia said on Friday that he wanted Morawiecki to present the new Cabinet to parliament for approval as soon as possible.
Polish voters elected a new set of 460 MPs and 100 senators when they went to the ballot box last month.
Morawiecki's conservative Law and Justice party won Poland's October 15 election, but lost its parliamentary majority and looks unlikely to stay in power for a third consecutive term.
A bloc of pro-EU opposition parties in mid-November secured a resounding victory in Poland's new parliament during its first key vote to elect a house Speaker.
Poland's opposition groups have signed an agreement to form a coalition government, pledging to restore the rule of law, promote green energy and relax abortion rules, among other policies.
Opposition leader Donald Tusk, a former top EU official, has already chosen most candidates for ministerial roles in his future Cabinet, according to the Rzeczpospolita newspaper.
Hołownia told reporters on Friday that "all the names of the members of Donald Tusk's future government have been agreed on."
Tusk was Poland's prime minister from 2007 to 2014.
