Abstract: It is usual to control human activities by blacklist measures for the protected area system with national park as its mainbody in China, which tends to one-size-fits-all in reality and implemented as accordance for accountability. In view of its bad effects on many occasions, it should be reflected scientifically. Some measures have been adjusted in policy and law latest released, which give resilient measures for some human activities for both core zone and general control zone in national park. However, one-size-fits-all policy to prohibit human activities in core zone in principle and unreasonable accountability still exists. The attributing factors of these issues can be concluded as three: ① the relevant administrative departments have an unclear understanding of the scientific meaning of "the strictest protection"; ② antiquated and unscientific policies and laws; ③ the mode of information collection and transmission of human activities can't match the needs of conservation. All of these result in upper level government failure on most occasions. It is analysed that positive and negative externalities from the information of human activities are asymmetrically distributed among different levels of government (and management institutions), and the related rights, responsibilities and interests do not match. In addition, the ways of obtaining information such as supervision and accountability are different from those of daily management. These lead to incompatible incentive on the occasion of information asymmetry. Consequently, it is safe to prefer "left" rather than "right" for the management agencies of protected areas, which tend to sloth administration especially in the field of promoting harmonious coexistence between humans and nature. Based on the views as above, it should be adopted that human activities are controlled by adapted management with white list, accordingly, the distribution of positive and negative externalities from the information of human activities should be adjusted among government and management agency of different level, so that the compatible incentive can be formed for the information collection and transmission by grass root administration, and adaptive management for human activities can be realized based on valid information mechanism.
