The 'Ease of Doing Business Index' is published by the World Bank as part of its Doing Business report, which assesses the regulatory environment in countries to determine how conducive it is to starting and operating a business. This index evaluates various factors, such as ease of starting a business, getting credit, and enforcing contracts, providing a comprehensive picture of the business climate. Understanding the World Bank’s role in this index is essential for UPSC aspirants, as it highlights the significance of international assessments in shaping domestic economic policies and attracting foreign investment, reflecting India's integration into the global economic system.
