The leading economic countries, also known as the major economies or global economic powers, are those nations that have the largest and most influential economies in the world. There are primarily two methods to determine which countries are considered leading economic powers:

1. Gross Domestic Product (GDP): GDP is the total value of goods and services produced within a country in a specific time period. Countries with high GDP generally have well-developed industries, strong investment, and a large consumer base. The leading economic countries based on GDP include:

- United States: The United States has the largest economy in the world, with a robust services sector, advanced technology, and a diverse range of industries.
- China: China is the second-largest economy and has experienced significant growth over the past few decades. It has a huge manufacturing sector, a large population, and substantial foreign trade.
- Japan: Japan has a highly advanced and technologically driven economy, with a strong emphasis on innovation and exports in industries such as automotive, electronics, and robotics.
- Germany: Germany boasts a strong manufacturing sector, particularly in automobiles, machinery, and chemicals. It is known for its precision engineering and high-quality exports.
- United Kingdom: The United Kingdom has a diverse economic base, including finance, manufacturing, and services. London is one of the world's leading financial centers.

2. Human Development Index (HDI): HDI takes into account not only economic factors but also social indicators such as healthcare, education, and standards of living. Countries with high HDI scores are generally considered to have well-rounded development. Based on HDI, the leading economic countries include:

- Norway: Norway consistently tops HDI rankings due to its high standard of living, well-developed education system, and strong social welfare programs, thanks to its oil wealth.
- Switzerland: Switzerland is renowned for its high quality of life, strong healthcare and education systems, and a thriving financial sector.
- Australia: Australia has a robust economy, high living standards, and a well-functioning education system, making it one of the leading economic countries.
- Netherlands: The Netherlands is known for its strong infrastructure, well-regarded healthcare and education systems, and a highly skilled workforce.
- Sweden: Sweden has a highly advanced economy, strong social support systems, and a reputation for innovation and sustainability.

It is worth noting that the rankings of leading economic countries can vary depending on the methodology and indicators used. GDP and HDI are commonly used, but other metrics, such as per capita income, inequality indices, or ease of doing business, can also provide different perspectives on economic strength.
