Artificial Intelligence，as one of the most influential technologies of the 21st century，is profoundly changing the business model of various industries，which realizes intelligent decision-making through big data analysis，machine learning，and large model computing，improves enterprise productivity，cultivates new service areas，and brings great changes to economic and social development.Generative AI is able to create a large and diverse amount of data by training generative models，which is crucial for many machine learning tasks.Currently，AI is showing explosive growth and has become a hotspot of concern for countries around the world.Generative AI does not completely replace traditional AI technologies，such as classification，clustering，prediction，etc.，and the two can complement each other to jointly promote the development and application of AI.Based on this，countries have introduced policies to promote the development of AI and generative AI，but they have also developed regulatory measures to ensure that AI and generative AI applications comply with laws，regulations and ethical principles，and to guard against the risk of data use，the risk of misuse of AI-generated content，the risk of misuse of AI algorithms and other risks.Through a comparative analysis of AI-related regulations and policies in the world，China，and domestic provinces and cities in 2023-2024，this paper combs through the development lineage and main features of AI regulations and policies，and conducts a preliminary assessment of their policy effects，and puts forward suggestions for strengthening international cooperation，improving the regulatory system，and promoting synergy between technological innovation and policies，with the aim of providing healthy development of China’s AI industry with The purpose is to provide useful reference for the healthy development of China’s AI industry.
