Abstract: Xi Jinping's important exposition on preventing and defusing economic risks is generated on the basis of drawing on and sublimating Marx's theory of economic crisis, inheriting and innovating Chinese excellent traditional culture, continuing and extending the successful experience of the Communist Party of China, and examining and grasping the domestic and foreign economic development situation. Xi Jinping's important exposition on preventing and defusing economic risks emphasizes that preventing and defusing economic risks requires the centralized and unified leadership of the Party as the political guarantee, the general tone of seeking progress while maintaining stability as an important principle, the smooth“domestic and international dual circulation”as the strategic deployment, the systematic financial risk prevention and control as the core link, and the pushing and realization of high-quality economic development as the phased goal, its core essence has raised the understanding of the whole Party on how to prevent and defuse economic risks to a new height. Xi Jinping's important discourse on preventing and defusing economic risks not only expands the cognitive domain of Marxist political economy, but also provides basic guidelines for our country to prevent and defuse economic risks. It also transcends the traditional global economic risk governance discourse system and has profound value implications in such aspects as theoretical innovation, practical orientation and discourse guidance.

Key words: economic thought, economic security, economic risk prevention
