    The development of cross-border e-commerce has gradually matured, and what is the input efficiency of its production factors? On the basis of the research hypothesis, the evaluation index system and the multiple linear regression model are constructed, and the empirical analysis is carried out Empirical analysis shows that the number of e-commerce enterprises and express revenue is significantly positively correlated with cross-border e-commerce, while labor input is significantly negatively correlated The asset investment, Internet penetration and the number of Internet users are not significantly correlated with cross-border e-commerce It can be seen that in the current cross-border e-commerce activities, there is a “crowded” state of production factors, and the excessive input of production factors makes the production efficiency not reach the best state, especially shown in the elements of capital input and labor input The number of enterprises is positively correlated with the growth of the cross-border e-commerce industry, while the basic elements of the Internet have little to do with the growth of the industry Therefore, we should cultivate high-quality cross-border e-commerce professionals, optimize the capital structure, improve the growth environment of the enterprises, and promote the development of the cross-border e-commerce industry

    The market reputation cannot achieve long-term incentives for the B2B platform In order to suppress the long-term moral hazard of the B2B platform, a two-stage principal-agent model that introduces market reputation and internal reputation is constructed. The inverse induction method is used to solve the incentive effect of the dual reputation under the two-phase cooperation, and the impact of internal reputation on the incentive contract is also compared and analyzed It is found that market reputation can only suppress the short-term moral hazard of B2B platform, while internal reputation can inhibit the short-term and long-term moral hazard of B2B platform, but its short-term incentive effect is worse than that of market reputation; the incentive mechanism under dual reputation can solve the problem that market reputation cannot realize the long-term incentives and can make up for the shortcomings of short-term incentives for internal reputation Therefore, the incentive mechanism based on dual reputation is more reasonable and effective for banks

    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
    Abstract768)      PDF(pc) (986KB)(1045)       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.

    Abstract1410)      PDF(pc) (1119KB)(954)       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.
