State capitalism’s supporters argue that it can provide stability as well as growth. Russia's wild privatisation under Boris Yeltsin in the 1990s alarmed many emerging countries and encouraged the view that governments can mitigate the strains that capitalism and globalisation cause by providing not just the hard infrastructure of roads and bridges but also the soft infrastructure of flagship corporations.

Both for their own sake, and in the interests of world trade, the practitioners of state capitalism need to start unwinding their huge holdings in favoured companies and handing them over to private investors.

Yet a close look at the model shows its weaknesses. When the government favours one lot of companies, the others suffer. In 2009 China Mobile and another state giant, China National Petroleum Corporation, made profits of $33 billion — more than China's 500 most profitable private companies combined. State giants soak up capital and talent that might have been used better by private companies. Studies show that state companies use capital less efficiently than private ones, and grow more slowly. In many countries the coddled state giants are pouring money into fancy towers at a time when entrepreneurs are struggling to raise capital. [my emphasis]

Rising powers have always used the state to kick-start growth: think of Japan and South Korea in the 1950s or Germany in the 1870s or even the United States after the war of independence. But these countries have, over time, invariably found that the system has limits. The Chinese of all people should understand that the best way to learn from history is to look at its long sweep.
