Abstract

In this paper, a stochastic SEQIR epidemic model with Markovian regime-switching is proposed and investigated. The governmental policy and implement efficiency are concerned by a generalized incidence function of the susceptible class. We have the existence and uniqueness of the globally positive solution to the stochastic model by using the Lyapunov method. In addition, we study the dynamical behaviors of the disease, and the sufficient conditions for the extinction and persistence in mean are obtained. Finally, numerical simulations are introduced to demonstrate the theoretical results., Comment: 14pages,5 figures, references 22

Abstract

Facing the dual pressure of domestic environmental pollution and international climate change mitigation, China, the world’s largest emitter of carbon emissions, has proposed a “double carbon” target of 3060. Fujian Province is a clean energy province and a major economic province in southeastern China, with inherent energy conservation and emission reduction advantages. However, as industrialization is still in progress and urbanization is accelerating, the problems of low industrial level and sloppy development are still prominent, and the future low-carbon transformation will be difficult and long. Based on the theory of industrial structure optimization and the theory of low carbon economy, this paper analyzes the influence mechanism of industrial structure optimization on carbon emission from three perspectives: efficiency improvement, technological progress, and structural adjustment. Secondly, an econometric model is constructed by combining the environmental Kuznets curve, and the time series data of Fujian Province from 2000-2021 are analyzed empirically to derive the optimization path of industrial structure on carbon emissions in Fujian Province through co-integration analysis, multiple regression, mediating effect analysis, and robustness testing methods. The results of this paper show that from the structure of energy consumption in Fujian Province, coal and oil consumption account for 72% of the total consumption, which is the main cause of carbon emissions in Fujian Province. The mediating effect and stability analysis of the optimization path through the benchmark regression model shows that the p-value variance is 0.0862, and there is no significant difference between them. The optimization path proposed in this paper has significant utility for carbon emission reduction, improves the efficiency of energy use, strengthens the introduction of FDI and industrial structure optimization in various regions of Fujian Province in a targeted manner, and provides a reference for decision-making for global industrial structure optimization and upgrading.

24. Media power and its control in contemporary China : the digital regulatory regime, national identity, and global communication

Author

Zhu, Yanling

Abstract

In the past decade, the cultural projection of China has become increasingly important to the Chinese Communist Party (CCP) and to the state in terms of maintaining ideological unity and social stability domestically while at the same time enhancing its soft power amid global competition. Since 2012, with the tightened regulatory framework of the state regulator, the National Radio and Television Administration (NRTA), broadcasters have increasingly engaged in the production and promotion of national discourse, which has embodied the official ideology. At an international level, the Belt and Road Initiative (a global infrastructure strategy initiated by the Chinese government in 2013 that seeks to connect Asia with Africa and Europe to improve regional integration) articulates with China's policy of deploying soft power to manage international relations. In analysing the shifting power dynamics of the documentary production sector, this thesis aims to capture this moment of transition in China's broadcasting policy. This thesis takes an ethnographic approach to discuss the policy practices within China's broadcasting industry. It uses document analysis, in-depth interviews and participant observation as its main methods, to explore the gap between the contemporary policy regime and its implementation in national broadcasters and streaming services, taking into account the interplay between broadcasters, political bodies, producers and audiences. It deals with the contemporary role of Chinese national broadcasters in mediating the public discourse, the collective reimagining of China's national identity, and the newly-found policy initiative of using state media as a means of nation branding. Cases investigated include China Central Television (CCTV) Documentary, China Global Television Network (CGTN), and the Shanghai Media Group (SMG), as well as co-productions made by CCTV and international media firms, including the BBC, Discovery and the Japan Broadcasting Corporation (NHK). During the fieldwork in China and the UK in 2019, I conducted 46 in-depth interviews with media professionals (including 36 semi-structured interviews), focusing on the challenges and possible solutions of media production and regulation. Tensions emerge not only between the tightening of control of a top-down production framework and the growth of commercial and creative forces, but also between the rise of a national regulatory agenda and a policy goal of global engagement. Situated in an increasingly competitive, globalised cultural sphere, this thesis argues that the state, media institutions and citizens in China are renegotiating a collective national cultural identity to overcome internal conflicts and enhance social stability; in the meantime, the interplay between political, commercial and professional forces continually shapes China's policy response to global communication, which is now seeking the role of public diplomacy in state media.

Subjects
Mathematics - Probability
Abstract

In this paper, we consider a mean-reverting stochastic volatility equation with regime switching, and present some sufficient conditions for the existence of global positive solution, asymptotic boundedness in pth moment, positive recurrence and existence of stationary distribution of this equation. Some results obtained in this paper extend the ones in literature. Example is given to verify the results by simulation., Comment: 11pages,3figures

47. M-estimation in high-dimensional linear model

Abstract

We mainly study the M-estimation method for the high-dimensional linear regression model, and discuss the properties of M-estimator when the penalty term is the local linear approximation. In fact, M-estimation method is a framework, which covers the methods of the least absolute deviation, the quantile regression, least squares regression and Huber regression. We show that the proposed estimator possesses the good properties by applying certain assumptions. In the part of numerical simulation, we select the appropriate algorithm to show the good robustness of this method, Comment: 16 pages,3 tables
