It is becoming a global trend to promote development of artificial intelligence industry by government. Based on comparative public policy theory, taking policy improvement as the oriented-purpose of comparative studies of artificial intelligence industrial policies will help policy-making departments improve the specific contents of the current policy text further. According to the policy comparative study general paradigm and logic, the comparative analysis framework guided by policy improvement is divided into five modules ,and the basic requirements are proposed, namely, policy comparison texts should be advanced, subjects should be benchmark, methods should be scientific, results should be causal, suggestions should be suitable. Each module of the existing comparative studies on artificial intelligence industrial policies whether meets requirements or not is judged. It is found that the existing studies can not fully meet the corresponding requirements of each module. In view of this, the main study directions of each module for further improvement are put forward.
