This document is the introduction to the 12th edition of the World Bank Group's annual Doing Business report. It provides an overview of the report, which measures regulations affecting 11 areas of business across 189 economies. Specifically, it measures regulations on starting a business, dealing with construction permits, getting electricity, registering property, getting credit, protecting minority investors, paying taxes, trading across borders, enforcing contracts and resolving insolvency. The introduction emphasizes that while fiscal and monetary policy receive more attention, the business regulatory environment is equally or more important for economic success. It positions the Doing Business report as an important resource for understanding the business regulations that underlie economic development.
