传统行政法学理论在行政活动分类问题上存在较为严重的不周延、不科学问题 ,这必将导致某些行政活动无论从理论上还是从实践上得不到控制或及时救济的后果。可以在比较大陆法系和英美法系国家的作法的基础上 ,借鉴其成功经验 ,提出新的思路和解决方案 ,对行政活动进行合理分类和有效控制。 The traditional administrative jurisprudence theory has more serious unscheduled and unscientific problems in the classification of administrative activities, which will inevitably lead to the result of some administrative activities being neither controlled nor promptly remedied in theory or in practice. Based on the comparison of the practices of the civil law system and the Anglo-American legal system countries, we can learn from their successful experiences, come up with new ideas and solutions, and properly classify and effectively control administrative activities.
