This study aimed to examine the prevalence and correlates of depression, anxiety, suicidal behavior, and the comorbidity of these mental health problems across Chinese multicultural adolescents and Korean monocultural adolescents. A range of demographic variables, family relationships, academic achievement, and individual problem behaviors were analyzed to identify the significant correlates. The analysis sample comprised 410 Chinese multicultural adolescents and 38,922 Korean monocultural adolescents, derived from the Korean Adolescent Health Behavior Survey in 2020. Chi-square statistics were estimated to examine significant differences in the prevalence of mental health problems across the two cultural groups. To identify significant correlates of the mental health problems, a series of bivariate logistic regressions were examined separately for the Chinese multicultural and Korean monocultural adolescents. Findings revealed that Chinese multicultural adolescents were at a higher risk for depression, suicidal behavior, and comorbidity of suicidal behavior with depression and anxiety, compared to their Korean counterparts. Despite these significant differences, this study found similar patterns of associations in terms of significant correlates of depression, anxiety, suicidal behavior, and their comorbidities. For both adolescent groups, the higher probability of these mental health problems was associated with drinking alcohol, smoking cigarettes, and smartphone overuse. Further, findings indicated that the impact of smartphone overuse and cigarette use on these mental health problems was higher among adolescents from Chinese multicultural families, compared to those from Korean monocultural families. Findings suggest that the same prevention programs targeting these individual problem behaviors are likely to reduce the risk of mental health problems, whether provided for adolescents from Chinese multicultural or Korean monocultural families, particularly for Chinese multicultural adolescents, where the influence of the problem behaviors on these mental health problems are stronger.

The Chinese art film projection industry plays an important role in the survival and development of Chinese art films. At present, domestic art films are mainly screened at single venues, such as the China Film Archive and Broadway Cinematheque, as well as the Nationwide Alliance of Arthouse Cinemas formed by commercial cinemas. The China Film Archive relies on the support of the government and is an institute that promotes public welfare, while Broadway Cinematheque relies on the substantial funds from its parent company. These two modes are not easily replicated and they do not contribute to furthering the progress of the art film industry. However, the Nationwide Alliance of Arthouse Cinemas has considerable commercial potential, meets the requirements for fundamental development, and a high value is placed on its development in China. With national attention directed on the film industry, the development of the art film market has also been highlighted. Based on an investigation of the current situation, the author thinks that there are some problems in the art film screening market as represented by the Nationwide Alliance of Arthouse Cinemas, such as insufficient diversity of film sources, unstable scheduling of film screenings, and that art films have not been properly promoted resulting in an inability to attract a sufficient audience. In this study, the relevant data were collected and analyzed qualitatively, and compared with the development of art cinemas in France and the United States. The following conclusions were obtained: Firstly, the film censorship process should be modified. The review committee should respect the laws of artistic creation, reduce the interference of non-artistic factors in movies, increase the proportion of professional reviews, attract younger reviewers, and improve the review mechanism. Since China currently cannot implement a film classification system, it should relax the restrictions on film censorship as much as possible to promote the prosperity and development of art films. Secondly, the government needs to increase and refine how it supports the art film industry and provide real support to different types of projection companies, such as box office compensation for losses incurred from showing art films instead of commercial films, improving the wages and welfare of art film industry workers, and increasing the relevant tax relief, subsidies and other preferential policies. Thirdly, theaters and cinemas should actively develop business models by forming their own unique viewing culture and atmosphere to cultivate a long-term stable audience. Finally, catering the favor of college students, art film culture should be shaped and developed on campuses, important venues to show these art films, which can both expand the customer base of art film by attracting college students, and enable art film to serve as an accelerator to cultivate college students’ appreciation in humanities. In this way, if all parties work together it is believed that the art film market will gradually grow and flourish.

The debate on the effectiveness of monetary policy has been going on for long. The real business cycle theory, which assumes a complete market and completely flexible prices, considers the monetary policy neutral, because it affects the nominal price only, with no effect on the real economic variables such as output and interest rate. However, the New Keynesian theory, which assumes an incomplete market and nominal rigidities, considers the monetary policy no longer neutral, and as affecting several real economic variables and leading to economic fluctuations in the short run. New Keynesian economics modified real business cycle method and add nominal rigidities, various shocks and frictions to construct the new Keynesian model, which is called Dynamic Stochastic General Equilibrium (DSGE) model. For the efficient implementation of monetary policy, it is important to understand the spillover effects of monetary policy to the real economy. To this end, this study investigates the effects of monetary policy on each part of the Chinese real economy. This paper estimates a closed medium-scale dynamic stochastic general equilibrium (DSGE) model and presents the dynamic monetary policy shock effects on the Chinese economy. We estimate some important parameter values by applying the Bayesian approach to quarterly data of three Chinese macroeconomic variables, output, consumption, and inflation, for the period from 1992:1 to 2018:4. The closed medium-scale DSGE model shows that a positive monetary policy shock has negative effects on the output, consumption, investment, labor, inflation, wage, and government consumption, whose values go down in the first period but then rise and finally revert to the steady-state values. Conversely, a negative monetary policy shock has positive effects on the output, consumption, investment, labor, inflation, wage, and government consumption in the short run. Our results are consistent with the findings of Smets and Wouters (2003, 2007) and Christiano, Eichenbaum, and Evan (2005).

The fourth industrial revolution is sweeping through all sectors of Chinese society and has its characteristics. The Multimedia content platform industry is a product of innovative business models, and it will be one of the first industries to be affected. In this study, choose the cutting-edge technology as the entry point, such as “the Internet of Things”, “Big Data” and “Artificial Intelligence” which have a great impact on China's image content industry and lead the fourth industrial revolution. Klaus Schwab's model of the Fourth Industrial Revolution is used to analyze the Chinese Multimedia content platform industry from the levels of “emerging technologies”, “economic growth”, “business models” and “state” to draw some conclusions: More new jobs are also created with the emergence of new industries. The development of science and technology promotes the emergence of video equipment with simpler and more portable operation in an endless stream and blurs the industry boundary that could not be passed by the image content industry in the past. At the macro-economic level, every industrial revolution in history has brought great impetus to economic growth, while in this revolution, the speed and breadth of dissemination of emerging technologies and innovative achievements in various fields are far greater than those of the previous revolutions. The emergence of platforms breaks the traditional image industry's single mode of communication by following the traditional communication mode and channel in terms of communication and the platform plays a role in integrating many functions, such as IP provision, industry publicity, internet film and television production, cross-media transformation of high-quality film and television resources in terms of production, and has quickly become the main field of film and television consumption, posing a challenge to the traditional image industry. The threat of super platforms usually comes from the innovation impacting and subverting the whole market. The platform taking "change" as the growth driving force knows about the power of “change” better than anyone else. Therefore, it is internet platform enterprises that respond first to the fourth industrial revolution. Whether it's Tencent, Alibaba, Baidu, or Byte Dance, they all put a lot of resources into the development and application of emerging technologies in the fourth industrial revolution and become the main leaders of China's fourth industrial revolution. It is worth noticing that the copyright issues brought by emerging technologies such as artificial intelligence and big data are affecting the development and scale of informatization and automation of related industries. The innovation driving force brought by the fourth industrial revolution injects kinetic energy into social and economic development and produces some new problems. Chinese Multimedia content platform companies are responding to the upcoming challenges with model innovation and vertical integration. If data are at the heart of the fourth industrial revolution, then multimedia content platforms will have access to vast amounts of data due to the scale of their markets and users and will be able to stay ahead of the competition. revolution injects kinetic energy into social and economic However, the monopoly of data by Internet oligarchs will pose a threat to the "fair environment" pursued by the market economy throughout the world. Some medium and small-sized enterprises might lose their competitiveness because of this, which thus slows down the innovation drive. At the production level of the film and television industry, it is reflected in the excessive pursuit of IP-based and content selective creation based on big data, resulting in the gradual homogenization and simplification of content. At the audience level, it is reflected that although the content needed by the audience can be easily and rapidly accessed, the right to explore and discover more diverse content has also been lost. The result is that the Chinese government is making positive changes in this revolution. Whether it is the introduction of policies and regulations related to Anti-Digital monopoly，the “digital government”, or the persistence of innovative transformation programs all reflect this commitment to change. The scale of industrial technology development is directly influenced by the government's macro-regulation. In the meantime, it is not only a development dividend for the growth of the industrial economy，but also brings challenges to the labor environment and fair environment of the image content industry.

This study raises the following question: Will the neoliberal political economic model turn out to be indisputably superior to the so-called “China model” after the novel coronavirus disease 2019 pandemic and the current United States–China rivalry end? This question is raised because the neoliberal political economic system has been slowing down since the global financial crisis of 2008, whereas the China model has performed considerably well. The current acceleration of the United States–China hegemonic rivalry makes this question a timely and relevant issue for investigation. Currently, the Western neoliberal political economic system is struggling with two fundamental problems: the increase in economic inequality and the rise of populism. This study defines the current situation of the neoliberal political economic system as being in a crisis owing to these problems. The neoliberal political economic system must tackle these problems not only to surpass China’s challenge but also to recover from its current crisis. Given this mindset, the major arguments of this study are as follows: The neoliberal political economic model, often called “the Washington Consensus,” that has dominated for 40 years in the neoliberal political economic world has increased income inequality. The decline of the middle class caused by this increasing inequality is one main reason why political populism has lately grown in many Western countries. In addition, the policy requirement of the Washington Consensus that was imposed by Bretton Woods institutions concerning developing countries has not been effective. In fact, it has caused much harm to developing countries by straining their potential for development. As long as advanced Western countries and Bretton Woods institutions hold on to the Washington Consensus in their attitude toward developing countries, the Beijing Consensus, also known as the China model, may seem more attractive to developing countries. The study argues that the neoliberal political economic system should be drastically reformed and the Washington Consensus should be left behind. The Washington Consensus has failed not only as an effective development model for developing countries but also as a sustainable model for advanced Western countries. To surpass the challenge of the China model, the neoliberal political economic system must confront the deteriorating income inequality problem and solve the current crisis. With regard to the issue of increasing income inequality, the China model is no better than the Washington Consensus; in fact, it may be worse. How China will deal with this problem and continue its economic growth remains to be seen.

This study explores whether American employees have different psychological contracts with subsidiary Korean companies than do Chinese employees, and if so, whether the different psychological contracts influence the job performance, job satisfaction, and job retention of employees of different nationalities. A survey of Chinese and American employees was conducted in China and in the USA during the summer of 2016. The 480 usable responses were analyzed with Hierarchical Multiple Regression. The results revealed significant differences in employees’ psychological contracts with Korean companies between American employees and Chines employees, indicating that psychological contracts with subsidiary Korean companies influenced job performance, job satisfaction, and job retention for all employees. However, national culture affected job performance more strongly for Chinese employees than for Americans. This result also indicated that subculture significantly influenced work efficiency and productivity. However, job satisfaction and job retention based on employees’ perceived psychological contracts was the same for Chinese and American employees. The study results implied that psychological contracts are measurable and are related to important organizational outcomes. However, interpretation of the results should be limited to study populations and Korean subsidiary companies.
