With the development of the Internet，the spread of child pornography in China is rampant. However，from the perspective of international comparison，the criminal basis and theoretical research on child pornography in China are seriously insufficient. To better protect minors，the United States began to attach importance to the criminal regulation of child pornography in the 1970s，gradually distinguishing “child pornography” from “obscenity，” prohibiting the possession of child pornography materials and banning virtual child pornography. To follow the international trend and protect minors，China can draw lessons from regulating child pornography in the U.S.，combined with the current network environment and China’s national conditions. Such as from the perspective of criminal law specifically defined child pornography to distinguish between child pornography and obscenity，child pornography-related behavior into sin，ban virtual child pornography on the Internet and increase criminal penalties for child pornography.
