The World Bank Group has released their annual Doing Business ranking data. Estonia ranks on 17th position, followed by Taiwan, China and Switzerland. In a series of annual reports Doing Business presents quantitative indicators on business regulations and the protection of property rights that can be compared across 189 economies, from Afghanistan to Zimbabwe, over time. The rankings for all economies are benchmarked to June 2014.
The ease of doing business index is an index created by the World Bank. Higher rankings indicate better, usually simpler, regulations for businesses and stronger protections of property rights. The index is based on the study of laws and regulations, with the input and verification by more than 9,600 government officials, lawyers, business consultants, accountants and other professionals in 185 economies who routinely advise on or administer legal and regulatory requirements.
The ease of doing business index is meant to measure regulations directly affecting businesses and does not directly measure more general conditions such as a nation's proximity to large markets, quality of infrastructure, inflation, or crime.
