Poland's improved ranking in the World Bank's Doing Business report is the result of years of steady work, Prime Minister Donald Tusk said after the country moved up to 55th place from 62nd last year.

Even though the report concluded that Poland was the top global improver in the past year, Tusk said the country’s performance was not yet satisfactory. He added that he would ask parliament to create a standing committee on deregulation.

The Doing Business report said that Poland has enhanced the ease of doing business through four institutional or regulatory reforms, making it easier to register property, pay taxes, enforce contracts and resolve insolvency.

Doing Business 2013: Smarter Regulations for Small and Medium-Size Enterprises assessed regulations affecting domestic firms in 185 economies and ranked the economies in 10 areas of business regulation, such as starting a business, resolving insolvency and trading across borders.
