The rise of state capitalism | The Economist

"...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."
