How much of the world economy is state-owned? Analysis based on the 2005–20 Fortune Global 500 lists

This paper analyzes the share of state-owned enterprises on the Fortune Global 500 lists from 2005 to 2020. The purpose is to answer two research questions—what is the share of SOEs among the world's largest companies, and is this share increasing over the years? Regarding studies of large sets of companies, the novelty of this article is the method in which SOEs were identified—based on the criterion of actual corporate control of the state and not the threshold of state ownership. The results show that the share of SOEs in the group of the world's largest companies is higher than indicated in previous similar studies, and this value has increased significantly over the last 15 years. In 2005, there were 64 SOEs on the list; in 2020, there were 141 (with the highest number—142—in 2015). In this period, the share of SOEs in revenues doubled (to almost 30%), in assets more than tripled and the total number of employees from SOEs from the list more than doubled. However, these increases were almost solely due to the growth of the Chinese economy, which resulted in more Chinese SOEs being included on the list.
