The guidelines, drawn up by the Ministry of State Assets, are designed to encourage state-controlled companies to give greater consideration to so-called "local content" when planning and carrying out investment projects.
Speaking at the start of a Cabinet meeting, Tusk said the government wanted projects carried out in Poland to generate the greatest possible benefits for domestic businesses, workers and researchers.
"We want investment projects in Poland to benefit Polish businesses, Polish workers, employers and scientists," Tusk said.
"From today, the participation of Polish companies is much better protected," he added.
The recommendations are not legally binding but are expected to serve as a framework for managers and officials overseeing public investment projects, state news agency PAP reported.
The Ministry of State Assets unveiled a code of best practices defining "local content" as the value of goods and services produced or provided by domestic entities.
The document introduces a scoring system intended to assess the extent to which a company can be considered Polish.
The criteria include ownership structure, tax residency, where taxes are paid and the share of business activity conducted in Poland.
Under the methodology, ownership by a Poland-based entity carries the highest weighting, accounting for 25 percent of a company's score.
Tax residency and payment of corporate income tax in Poland account for 15 percent, while generating more than half of annual sales in Poland carries a weighting of 10 percent.
Companies can receive an overall score ranging from 0 to 100 percent depending on how many of the criteria they meet.
The recommendations apply to the entire investment process, from planning and procurement to project monitoring.
Among the proposed measures are the early publication of information on planned procurement procedures, giving domestic firms more time to prepare bids, and greater scrutiny of unusually low offers.
The guidelines also recommend taking contractors' experience on comparable projects into account.
The Ministry of State Assets has said the initiative reflects a broader global trend toward strengthening domestic industrial capacity and supply-chain resilience.
Tusk said in April that his government would use all legal tools available under European Union rules to support domestic businesses and expand local-content requirements.
He argued that geopolitical tensions, including Russia's war in Ukraine and instability in the Middle East, have underscored the importance of secure supply chains, energy resources and access to advanced technologies.
While reaffirming Poland's commitment to the EU single market, Tusk said the country would pursue policies aimed at strengthening its domestic industrial base.
