In China, most of peer-to-peer (P2P) lending platforms do not possess operational sustainability due to excessive defaults. To address this problem, the conflict of interests among P2P lending participants is discussed using a stakeholder approach. An evolutionary game model (EGM) of three players is developed to analyse the interactions among regulatory authorities, P2P lending platforms, and borrowers. Then, the asymptotic of the equilibrium and evolutionary stability strategies of the EGM are analysed. Results indicate that either the P2P lending platforms or borrowers will choose “noncompliant operation” or “default” strategies from a short-term perspective, and the strict supervision of the P2P lending platform in the short term is necessary for the sustainable operation of the platform. When supervision is intensified in the early stage and regulatory pressure becomes a normal state, P2P lending platforms and borrowers will actively select “compliant operation” and “repayment” strategies even if there is a lack of regulation in the future. Meanwhile, the behavioural strategies of P2P lending participants can be changed to conform to the sustainability of P2P lending by reducing the costs of strict supervision and increasing the damage caused by general supervision, reward and punishment coefficient for P2P lending platforms, repayment incentives of borrowers, and defaulting opportunity costs. Finally, suggestions for regulating the behaviours of P2P lending participants and promoting sustainability of P2P lending industry are discussed.
Both the suddenness and seriousness of COVID-19 have caused a variety of public opinions on social media, which becomes the focus of social attention. This paper aims to analyze the strategies regarding the prevention and guidance of public opinion spread under COVID-19 in social networks from the perspective of the emotional characteristics of user texts. Firstly, a model is established to mine text-based emotional tendency based on the Susceptible-Infectious-Susceptible (SIS) model. In addition, a mathematical and simulation analysis of the model is presented. Finally, an empirical study based on the data of microblog contents regarding COVID-19 public opinion in the Sina Weibo platform from January to March 2020 is conducted to analyze the factors that boost and hinder COVID-19 public opinion. The results show that when positive emotion is higher than 0.8, the spread of negative public opinion can be blocked. When the negative emotion and neutral emotion are both below 0.2, the spread of COVID-19 public opinion would be weakened. To accurately guide public opinion on COVID-19, the government authorities should establish a public opinion risk evaluation and an early warning mechanism. Platforms should strengthen public opinion supervision and users should improve their media literacy. The media organizations should insist on positive reporting, improve social cohesion, and guide the trend of public opinion.
Recent frequent “thunderstorm incidents” of the internet financial platforms (IFPs) have caused the panic of investors. In order to measure and reduce the investment risk of IFPs, the focus of this study is to evaluate the reputation of IFPs regarding investment risk. First, the reputation evaluation indicator system of IFPs is constructed from two dimensions of direct and indirect reputations. Then, based on this system, an improved fuzzy evaluation approach (IFEA) integrating the method of fuzzy comprehensive evaluation (FCE), the analytic hierarchy process (AHP), and the factor analysis (FA) are proposed for evaluating the reputation of IFPs. Finally, a case study based on the data of 20 peer-to-peer (P2P) lending platforms from “Home of Online Loans” (HOL) in China is used to illustrate the IFEA. Results show that the IFEA can reduce uncertainty and randomness in the determination process of indicator weight and membership degree and therefore accurately obtain the reputation level of IFPs and help investors make better decisions. Meanwhile, the key factors in determining the reputation of IFPs are identified, thereby improving the reputation level of the IFPs.
Федеральное государственное бюджетное образовательное учреждение высшего образования «Российский государственный педагогический университет им. А. И. Герцена», институт музыки, театра и хореографии; Санкт-Петербург, Россия Статья посвящена содержательным аспектам китайских фортепианных концертов. В качестве носителя смысла исследуется семантика. Примеры семантики приводятся из трех программных концертов: «Река Хуанхэ» Инь Чэнцзуна и творческой группы-Чу Ванхуа, Лю Чжуан, Шэн Лихуна, Ши Шучэна и Сюй Фэйсина, «Горный лес» Лю Дуньнаня и «Красота весны» Ду Минсиня. Одна из важных типологических особенностей китайских фортепианных концертов обусловлена обращением к модели европейского классического инструментального концерта в плане трактовки формы, исполнительского состава, роли солирующего инструмента, его соотношения с оркестром и т. д. Все композиторы изначально стремились воплотить в европейском жанре национальное музыкальное содержание. Оно реализуется, прежде всего, через семантический комплекс. Исходя из иерархии смысловой значимости, его можно классифицировать следующим образом: 1) семантика образов природы, 2) семантика звучания народных инструментов, 3) семантика популярных в китайской среде мелодий, 4) жанровая семантика, 5) семантика средств музыкальной выразительности. Введение семантики в тематизм несет коммуникативную функцию. Немаловажное значение имеет и то, что наличие семантического спектра в художественном тексте естественно для сознания и художественного восприятия китайца
