The figure disappointed analysts, who had predicted a 2.3-percent increase in their consensus forecast, Poland's PAP news agency reported.
In month-on-month terms, Polish industrial production in December was 8 percent lower than in November, the Statistics Poland (GUS) agency said.
Meanwhile, the country's seasonally-adjusted industrial production went down by 0.3 percent in year-on-year terms in December, while decreasing 1.1 percent month on month, the state-run statistics office reported.
According to the European Union's Eurostat statistics agency, which uses a different methodology, seasonally-adjusted industrial production rose 0.9 percent in November compared with the same month in 2023.
