    Consolidating the sense of the Community for the Chinese Nation is the main line of the work on ethnic affairs in the new era. Many historical factors contributed to the formation of the sense of the Community for the Chinese Nation. The Han nationality as the main ethnic group in China played a leading role in the formation and development of the Community for the Chinese Nation. A strong central government provided political guarantees. The political idea of “unification of tianxia” was the cultural motivation. Resettlement and development comprised an important economic and social factor that laid the foundation for the formation and development of the Community for the Chinese Nation. Summarizing its historical factors is conducive to in-depth study and comprehension of General Secretary Xi Jinpings statements on consolidating the sense of the Community for the Chinese Nation, thereby improving the conscientiousness of Party members and officials as well as the masses of all ethnic groups to consolidate the sense of the Community for the Chinese Nation.

    TANG Jie, ZHANG Bin
    Journal of Beijing University of Posts and Telecommunications(Social Sciences Edition)    2021, 23 (6): 1-12.   DOI: 10.19722/j.cnki.1008-7729.2021.0153
    Abstract390)      PDF(pc) (1013KB)(119)       Save
     A privacy boundary management model is proposed based on communication privacy management theory to elaborate how App users demarcate and regulate their privacy boundaries and analyze the important role that the proxy privacy assurance approaches play in the formation of privacy boundaries. Results indicate that government regulation is more effective than industry self-discipline in promoting the formation of privacy boundaries while privacy policies and privacy protection technologies of companies exercise a crucial influence over shaping App users risk perception and control perception. Privacy risk perception and control perception are two vital factors that ultimately influence their willingness to authorize their personal information. Information sensitivity and information relevance have significant influence on users privacy risk perception. Moderated by information sensitivity, there is apparent discrepancy in the degree of influence of perceived privacy policy effectiveness on perceived privacy risk.

    Abstract364)      PDF(pc) (944KB)(120)       Save
     41 policies related to new type of research institutes promulgated by the central government since 2016 are studied. Based on the dimensions of policy tools and the value chain of technological innovation, a policy analysis framework for new type of research institutes has been established. The content analysis method is used to quantitatively analyze the relevant policies of Chinas existing new type of research institutes. The study shows that there is a certain degree of inconsistency in the use of policy tools in the policies of Chinas new type of research institutes. Environmental policy tools are not fully used, demand-based policy tools are rarely used, and supply-based policy tools are used too frequently; attention is paid to the basic research stage, and policy support for technology incubation and industrialization stages is insufficient. On the whole, more attention is paid to the supply side and the basic stage. It is recommended to improve the top-level design of new type of research institutes, control the intensity of the use of policy tools and optimize the application structure of policy tools to support the development of Chinas new type of research institutes.

     From the perspective of social presence, a mediated model is constructed to investigate the influence of user experience in virtual community of second-hand e-commerce platform on transaction intention of buyers and sellers through social presence, and the differences of this mechanism on buyers and sellers are emphasized. A total of 512 and 467 valid samples were collected separately from buyers and sellers and a partial least squares structural equation modeling (PLS-SEM) is used. The results show that in the user experience of the virtual community of second-hand e-commerce platform, information experience and social experience affect user trust through social presence, and then affect transaction intention. The effect of social experience on social presence of buyers and sellers is different, and the effect of trust on transaction intention is also different. In the second-hand e-commerce platform, users’ trust in the platform plays a major role in their transaction intention, while the trust in the transaction object has a little effect. This study enriches research theories of second-hand e-commerce, and is valuable in guiding the further development of second-hand e-commerce.

    Following the calculation logic of “contribution degree-increment-total amount”, and based on the construction of a digital economy accounting framework, the digital economy scale of nine representative provinces in the four major urban agglomerations: Beijing-Tianjin-Hebei, Yangtze River Delta, Chengdu-Chongqing, and the Guangdong-Hong Kong-Macao Greater Bay Area, from 2003 to 2019 is calculated, and the differences of regional development in these urban agglomerations are analyzed. The findings are as follows: Digital technology drives the collaborative improvement of industrial digitization and digital industrialization through substitution effect and penetration effect, and promotes economic growth. There is a large digital divide within the Beijing-Tianjin-Hebei urban agglomeration. The Yangtze River Delta urban agglomeration plays a good regional synergistic effect and shows the transformation of the old and the new digital economy growth poles. Chengdu-Chongqing urban agglomeration has obvious dual-core balanced development pattern of digital economy.  Digital industrialization is prominent in the Guangdong-Hong Kong-Macao Greater Bay Area, but the proportion advantage of industrial digitalization is not significant due to the characteristics of industrial structure, and the penetration dividend of digital technology is gradually becoming saturated. On this basis, policy suggestions are put forward to promote the high-quality and balanced development of regional digital economy.

    Abstract265)      PDF(pc) (917KB)(65)       Save
    The core technology of data scraping is web crawling. In an era of big data, data scraping is beneficial to the social development while incurs plenty of risks, such as infringement of information system security, personal information security, information function, and copyright. There are some difficulties on identifying the criminal liability for data scraping. For instance, it is difficult to analyze interests, identify acts and evaluate harm. In the USA, the model of context was created and applied to the amendment of Computer Fraud and Abuse Act and related administrative law. To overcome these difficulties, it is necessary to learn from USA experience and add some provisions concerning “illegal access” and “illegal acquisition” to the criminal law, to present the hallmark of web crawlers in the administrative law and to clarify the quantitative factors of crime of harm in the judicial interpretations.

      Based on the articles accepted by Physical Review E (PRE) from 1993 to 2016, the influence of academic groups is comprehensively evaluated by combining social network analysis and the entropy weight method and the fuzzy comprehensive evaluation method. Firstly, co-authorship network in view of the co-authorship relationship among authors is constructed, and the invisible academic groups in the field of physics is identified by community partition algorithm. Moreover, through exploring the relationship between each index and the influence of academic groups, the influencing factors of academic groups are defined, and then the index system for evaluating the influence of academic groups is constructed. Finally, the entropy weight method (EWM) and the fuzzy comprehensive evaluation method are combined to construct a comprehensive evaluation model of the influence of academic groups. The analysis enriches influencing factors of academic groups and enlarges disciplinary fields of academic groups and academic influence, which provides new ideas for further related research.

    The study tries to extend the theoretical connotation of enterprise innovation strategies. An ecological perspective was applied to distinguish interactive relations among innovation strategies. Theoretical framework was based on government-business environment, innovation strategies, basic resources and their interactions under the reform of government functions. Adopting a new research technique which combines NCA and fsQCA methods, the influence of internal and external characteristics of enterprises on innovation performance is analyzed through configurational perspective. Results show that: High assets scale is a prerequisite for high innovation performance, while the other factors arent prerequisites. Meanwhile, there are two configurational routes for high innovation performance, including single dominant innovation strategy in “the plundering hand” and dual symbiotic innovation strategies in “the helping hand”. It also reflects when interaction between government and market transforms from predatory competition to mutual benefit, the relationship of innovation strategies changes dynamically from the “imbalanced” state to the dual symbiotic relationship, and finally, two innovation strategies will influence the emergence of high innovation performance.
