Ever wondered how the world’s companies stack up compared to countries? A new ranking looks at government revenue, and compares it to some of the world's most profitable businesses.

The list from Global Justice Now – an NGO – ranks the world’s top 100 global economic entities. Sixty-nine of the 100 are corporations, leaving room for just 31 countries on the list.

Corporations versus countries

The USA tops the list, which takes government revenue from the CIA World Factbook. 2015 estimates place US government revenue at $3.3 trillion.

China takes second place, with Germany in third. The top 10 is dominated by countries, with only Walmart breaking the monopoly. The US-based retail giant has revenues of over $480 billion according to the Fortune 500.

By taking 10th place, Walmart beats the government revenue of major global economies including Australia, South Korea and India.

From Walmart down though, it’s basically all about businesses, with only 22 more countries featuring.

The business monopoly

The following chart shows the top 10 biggest corporations, and their place in the overall rankings.

State Grid is the world’s second largest business – by revenue – and 14th overall. It starts a run of three Chinese businesses, with China National Petroleum (15th) and Sinopec Group (16th) following. All three have greater revenue than the South Korean government, with annual revenues of around $300bn.

Royal Dutch Shell follows (18th overall), coming in ahead of Mexico and Sweden, while Exxon Mobil, Volkswagen and Toyota Motor are all bigger than India’s state revenue.

Apple and BP complete the top 10, with revenues that exceed the government revenues of Switzerland, Norway and Russia.

It’s important to note the limitations of the comparison though. Government revenues generally represent a lower figure than GDP. For example, Russia’s government revenues of $216 billion pale in comparison to their GDP of more than $1.3 trillion.

A globalized world

What is clear from the ranking is the global spread of economic power. Brazil, South Korea and India all feature in the top 20 countries.

The 10 biggest businesses also have a distinctly global look. From China, to Holland and Japan, it’s far from a US monopoly.
