Enterprise Surveys and Doing Business are complementary, but different approaches to benchmarking the quality of the business environment across countries.
An Enterprise Survey is a firm-level survey of a representative sample of the private sector in an economy. The surveys cover a broad range of business environment topics including access to finance, corruption, infrastructure, crime, competition, and performance measures. Firm-level datasets, the investment climate indicators derived from them, as well as research papers are available on the website.
Doing Business focuses on measuring the complexity of business regulations and quantifying the ease of doing business across countries via indicator sets and rankings. The indicators cover common transactions such as starting a business or registering property based on standardized case-studies.
