As a landmark event in twentyfirst Century, the outbreak of the financial crisis in 2008 shocked the foreign scholars traditional knowledge of the market economy. By analyzing the views of foreign scholars, we can draw the following four points. First, the financial crisis has completely exposed the spontaneity, blindness and cyclical nature of the market economy, indicating the end of the laissez faire market. Secondly, the relationship between the state and the market is not a zero sum game. The state is not an obstacle to economic prosperity as the new liberals claim. Thirdly, the pursuit of profit maximization and the service of minority people in the market economy inevitably affect the implementation and effect of democracy. Forthly, the market economy is a neutral adjustment tool. It can be combined with other social structures, including socialist society. The viewpoints of foreign leftist scholars can provide useful reference for adhering to and developing our socialist market economy.
