Private entrepreneurs and private enterprises play an irreplaceable role in China's economic development. In recent years, China has promulgated criminal justice protection policies for private enterprises and has achieved initial results. Only by ly explaining and responding to the legitimacy of criminal justice protection policies for private enterprises and integrating them into the criminal legal system to be ruled by law can we fundamentally gain social recognition, stabilize expectations, and build confidence. The criminal justice protection of private enterprises (entrepreneurs) can be realized through the leniency system of pleading guilty and accepting punishments. Pleading guilty and accepting punishments are the legitimate basis for lenient protection of private entrepreneurs and private enterprises, and compliance is an advanced form for enterprises to plead guilty and accept punishments. Corporate compliance provides a system response to the legitimacy of the criminal justice protection of private enterprises: Compliance is not only conducive to crime prevention, but also conducive to investigation and punishment of crimes; the corporate leniency system of pleading guilty and accepting punishments with compliance as the core is conducive to corporate to reform, operate in compliance with regulations, and better assume social responsibility.
