    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.

     Taking Chinas A-share listed companies from 2011 to 2017 as research samples, the relationship between executive turnover and the risk of stock price crash is empirically tested. The results show that without distinguishing the turnover type, the executive turnover will reduce the risk of stock price crash, but after distinguishing the turnover type, the normal executive turnover will reduce the risk of stock price crash while the forced turnover will increase the risk of stock price crash. Furthermore, due to the different ways and purposes of executive appointment in state-owned enterprises and private enterprises, the samples are divided into the state-owned enterprise group and the private enterprise group and tested respectively. It is found that private enterprises are still in line with the above conclusions, while the relationship between forced turnover in state-owned enterprises and the risk of stock price crash is not significant. The meaning of listed companies executive turnover is explained to provide investors a new perspective of analysis. This has practical significance to understanding the meaning of executive turnover and reducing the risk of stock price crash.

    ZENG Ling-ling, YE Tian-tian
    Journal of Beijing University of Posts and Telecommunications(Social Sciences Edition)    2021, 23 (1): 69-79.   DOI: 10.19722/j.cnki.1008-7729.2020.0103
    Abstract1453)      PDF(pc) (1119KB)(1059)       Save
    The theoretical mechanism of green finance affecting green total factor productivity (TFP) is analyzed, and then based on the panel data of 30 provinces and cities in China from 2005 to 2017, green TFP is estimated by using SBM(Slack-based Measure) directional distance function and Global Malmquist-Luenberger (GML) index, and a green financial index system is constructed and the development level of green finance is estimated by using entropy method. Then, the static IV-GMM regression model and mediation effect model are used to systematically investigate the impact of green finance on green TFP and its mechanism. The results show that Chinas green finance is still at a relatively low level of development while green TFP shows the trend of growth, and both of them show great provincial and regional differences. The regression results show that the development of green finance can significantly promote the growth of green TFP in both coastal and inland areas and the whole country, but it plays a greater role in promoting coastal areas. The mediation effect test results show that for the whole country, the mediation effect of industrial structure optimization, energy saving and emission reduction and green technology innovation is significant, while only the mediation effect of energy saving and emission reduction and green technology innovation is significant in coastal and inland areas.

    DU Wei-an, XIONG Tong
    Journal of Beijing University of Posts and Telecommunications(Social Sciences Edition)    2021, 23 (2): 36-44.   DOI: 10.19722/j.cnki.1008-7729.2020.0277
    Abstract831)      PDF(pc) (986KB)(1161)       Save
      Using the data of China Household Financial Survey in 2017, the effect of financial literacy on household risk assets allocation is investigated from two aspects: primary financial literacy and advanced financial literacy. The primary financial literacy and the advanced financial literacy variables are constructed by factor analysis method, and then empirical research is made by constructing Probit and Tobit models. It is found that families with high financial literacy are more likely to participate in the financial market and increase their risky assets holding. After controlling endogeneity, the influence of primary financial literacy on household risk assets allocation is stronger than that of advanced financial literacy. The age of the householder, income level, social insurance and regional economic level can promote household risk assets investment, while householder risk aversion has the opposite effect. This paper believes that improving financial literacy of Chinese residents, especially primary financial literacy, is conducive to promoting the active and healthy development of the financial market and improving the financial well-being of residents. It is an indispensable link in the implementation of inclusive financial services.

    SHI Wenhua, LIU Lijie, RAN Hua, HUANG Laien
    Journal of Beijing University of Posts and Telecommunications(Social Sciences Edition)    2022, 24 (6): 28-38.   DOI: 10.19722/j.cnki.1008-7729.2022.0098
    Abstract221)      PDF(pc) (973KB)(359)       Save
     With the development of the Internet, enterprises’ algorithmic ethical responsibility has attracted much attention from scholars. However, there is no clear definition, measurement and impact on enterprise operation. The concept of “algorithmic ethical responsibility” is proposed to describe Internet enterprises’ responsibility of developing and utilizing algorithms under the requirements of basic social moral concepts, norms and values, and “algorithmic ethical responsibility” is taken as a new dimension of Internet enterprises’ social responsibility. Two sub studies are included. In Study 1, a scale of algorithmic ethical responsibility for Internet enterprises is developed, and the reliability and validity of the scale is verified. In Study 2, the impact of algorithmic ethical responsibility on corporate reputation and customer satisfaction is examined through structural equation model. The results show that, similar to the impact of other dimensions of corporate social responsibility, algorithmic ethical responsibility can also affect customer satisfaction through corporate reputation. Finally, the theoretical and practical implications of the research are discussed.

      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.

    XIE Yongjiang, YANG Yongxing
    Journal of Beijing University of Posts and Telecommunications(Social Sciences Edition)    2022, 24 (5): 18-25.   DOI: 10.19722/j.cnki.1008-7729.2022.0055
    Abstract1388)      PDF(pc) (910KB)(565)       Save
     With the rapid development of big data and artificial intelligence technology, algorithms, as one of the core technologies of artificial intelligence are widely used in human society. While promoting the development of the industrial economy and facilitating human life, it also brings serious problems of algorithmic discrimination. Algorithmic discrimination not only infringes the legitimate rights and interests of specific entities, operators’ competitive interests, and people’s basic human rights at the direct level, but also deepens existing prejudice and aggravates the digital gap, which are not conducive to the long-term development of the artificial intelligence industry and need to be regulated urgently. By tracing the causes of algorithmic discrimination, it can be seen that algorithmic discrimination is the result of algorithm developers’ implicit bias embedded in algorithms, data deviation and algorithm black boxes. Algorithmic discrimination is a legal issue in the technical field. Based on referring to the extraterritorial mode, the regulation of algorithmic discrimination needs to adopt multiple means such as law, technology and social norms to achieve the coordinated effect of algorithmic discrimination governance.

    Abstract682)      PDF(pc) (941KB)(534)       Save
    In order to promote the high-quality development of China’s economy, the impact of digital finance on the high-quality economic development is theoretically analyzed based on the perspective of financial functions, and the 2011—2018 provincial panel data is used to empirically test the hypotheses of the theoretical analysis. The empirical results show that digital finance can promote high-quality economic development by improving financial availability and resource allocation efficiency. In the heterogeneity test, it is found that targeted digital financial supervision can enhance the promotion effect; in addition, the promotion effect will be affected by regional heterogeneity. The promotion effect in the central region is greater than that in the west, and the least is the east. Therefore, in order to promote the high-quality development of China’s economy, it is necessary to strengthen targeted financial supervision and prevent systemic financial risks while accelerating the development of digital finance.

    Based on the social categorization theory and information decision making theory, taking 2091 non-financial listed companies in Shanghai and Shenzhen Stock Markets from 2013 to 2017 as a sample, the panel threshold model is established to investigate the employment effects of enterprise innovation under the different proportions of returnees in the executive team. The empirical results show that the returnee enterprises have stronger technological innovation preferences than the local enterprises. As for the whole sample, with the increase of the proportion of returnee executives, the enterprise technological innovation in the three threshold intervals are respectively presented as a spiral upward characteristic of promoting, inhibiting, and promoting the employment. Taking property rights into account, with the increase of returnees social categorization rate, non-state-owned enterprises show more sustainability and stability in promoting employment through technological innovation. The mechanism of the influence of returnee categorization degree on innovation preferences and the transmission channels of employment creation and employment destruction are explained. The research conclusions provide useful policy inspiration for Chinas technological innovation, international talent strategy, enterprises personnel selection and appointments mechanism and state-owned enterprise reform.

    MA Xiaofei, BAI Xuesong
    Journal of Beijing University of Posts and Telecommunications(Social Sciences Edition)    2021, 23 (5): 19-30.   DOI: 10.19722/j.cnki.1008-7729.2021.0166
    Abstract1841)      PDF(pc) (1175KB)(732)       Save
    At present, China has passed the first stage of the “three-step” strategy of artificial intelligence. Entering the high-end link of the global value chain is the main task in the next stage. Accelerating the development of artificial intelligence has reached a consensus not only in China but also in other countries. This study adopts the method of quantitative content analysis of policy literature, and takes 34 national policies closely related to the artificial intelligence industry issued from 2012 to 2020 as the analysis basis. Based on the time when the State Council issued the Development Planning for a New Generation of Artificial Intelligence, two stages are divided to explore the use and distribution of policy tools at the national level and the application changes in the artificial intelligence industry chain. The results show that: (1) Since the promulgation of the Development Planning for a New Generation of Artificial Intelligence, the number of government documents and the frequency of using policy tools are higher than those in the previous stage. There are more and more joint documents issued by departments, and the policy theme develops from macro level to subtle level; (2) The use of policy tools in the two stages is less and less from supply type to environment type to demand type. Moreover, the frequency of the use of environment and demand-oriented policy tools decreased compared with the previous stage; (3) The policies of the two stages involve all levels of the artificial intelligence  industry chain, but the focus is shifted from the basic layer to the application layer. Finally, some policy suggestions are put forward for the above problems, hoping to provide thoughts and inspiration for the development of artificial intelligence industry in the next stage.
