[Purpose/significance] The conceptual definition, type division, and analysis of the causes of typical risks and the impact relationship between risks of online information content ecosystem security risks are carried out, in order to provide an analysis basis for the research on ecological security governance of online information contents. [Method/process] Through a summary of the continuously derived online information content ecosystem security risks, combined with the online information security risk prevention, control and governance issues of national concern, the specific types of online information content ecological security risks were analyzed. From the overall perspective of online information ecosystem security risks, this paper analyzed the connotation and cause of the mainstream and typical types of risks, and summarized the overall characteristics of the ecological security risks of online information content. And from the perspective of the relationship between the ecological security risk of specific types of online information content and the overall risk, this paper comprehensively analyzed the possible impacts of the overall security risk. [Result/conclusion] Online information content ecosystem security risks are the core component of online information ecosystem security risks. Various types of online information content ecosystem security risks have different causes, but they overlap in characteristics and impacts. To ensure the security of the online information content ecology, it is necessary to specifically address the online information content ecosystem security risks of different types and comprehensively consider their overall risk impacts.

[Purpose/significance] Network information content governance has become an important part of national strategy and an important measure to build a cyber power. Identifying and deconstructing the risks of network information content security is an effective way to diagnose the key and difficult points of network information content governance. [Method/process] Combining literature investigation with the Regulations on Ecological Governance of Network Information Contents, this paper conducted research and carried out feature analysis of network information content security risks; With content analysis method, this paper made a quantitative analysis of the network information content governance incidents published by Cyberspace Administration of China in the past seven years; With social network analysis method, this paper analyzed the relationship between the elements related to the risks of network information content security in governance, and deconstructed scene elements. [Result/conclusion] This paper divides the risks of network information content security into 9 types, and analyzes the connotations and characterizations of each risk. The evolution trend of the risk is related to the development of network new media technology, unexpected public safety incidents and the changes of policies and regulations related to network governance. There are differences among the scene elements of different types of risk, such as the significantly low participation of information service platforms, and little attention to the network ideology risk or the cultural invasion risk. In terms of governance objects, this paper proposes that it is necessary to further subdivide the characteristics of network information content security risks, especially in establishing the risk assessment system of network information content security. In terms of governance subjects, the key point is clarifying the main responsibility of network information service platforms. In terms of fundamental governance principles, we need to focus on the network information content governance in the view of a holistic approach to national security.

[Purpose/significance] Summarizing and reflecting on the current status and deficiencies of the ecological security risk governance actions of network information contents is to improve the effectiveness of future governance actions. [Method/process] The article investigated and sorted out the characteristics of the four major governance actions, "periodical theme-based special actions", "fixed-point targeted special actions", "big content service platform targeted actions" and "emergency-related special actions" for the ecological security risk governance of network information contents, benchmarked the Regulations on the Ecological Governance of Network Information Contents, and analyzed the deficiencies of existing governance actions in five aspects of governance objectives, governance participants, governance objects, processes and methods of governance and governance tools. [Result/conclusion] The article finally puts forward the logic of network information content ecological security risk governance actions based on "PDCA-5 dimensional elements" framework. In addition, the article also proposes the upgrading and combination strategies of four types of actions: rights-based sports governance actions, normalized participatory governance actions, constructive active governance actions and perception-based smart governance actions.

[Purpose/significance] Network information service platforms provide great convenience for citizens’ life, however, the problem of users’ personal information security risk is increasingly serious, thus identifying and preventing risks are vital to enhance the governance capacity of network space and promote modernization of the governance system in cyberspace. [Method/process] Through cluster analysis on privacy policies of 117 sample Apps, this paper found out potential risk types of users’ personal information security. [Result/conclusion] This paper illustrates that the ecological environment of network space consists of the small ecology of the third party in the process of network information service, the internal ecology of network information service platforms, and the external ecology of network information service platform industry groups. According to that, this paper puts forward effective paths of personal information security risk governance form aspects of specifying platform privacy policies, regulating internal control mechanism of platforms and the interaction mechanism with the third parties, as well as playing the main role of government governance.

[Purpose/significance] The ecological security risk of network information content is a new type of information ecological security problem, which affects and threatens the overall national security from multiple dimensions. [Method/process] Based on the theory of holistic governance, intelligent governance and technological intermediation, this paper put forward the concepts, logical relations and basic contents of the theoretical framework construction of holistic intelligent governance of network information content ecological security risk, and specifically explained the significance of the theoretical framework construction of holistic intelligent governance. [Result/conclusion] The paper signifies the theoretical framework construction of holistic intelligent governance of network information content ecological security risk is an organic fusion of integrity and intelligent governance with information technology as the intermediary. In order to specifically promote its organization and implementation, the implementation path can be selected from the construction of an institutionalized mechanism guarantee system and the implementation of an intelligent technical support system.
