In an era of the widespread use of technology and digital connectivity the social on consumer behavior, particularly in relation to purchasing decisions, has become a highly significant. This explores the intricate connection between adolescents' use of social media and their inclination towards making purchases. Adolescence is a crucial stage where individuals shape their identities and consumption patterns due to significant cognitive and emotional development. The rapid rise of social media platforms has blurred the line between personal content and advertising, resulting in adolescents being exposed to their perceptions of what is desirable and normal when it comes to consumption. This research investigates various aspects of how social media affects adolescents' intention to, sociocultural, and economic factors, idealized portrayals of lifestyles and possessions social media can create aspirations that surpass one's financial means, leading to feelings of inside financial strain. Additionally, this study examines how social media mediates consumer engagement, industry-specific influences, trust-building processes through peer communication channels across different countries' perspectives as well as brand attitude formation among teenagers who are consumers with unique dynamics. Collectively, these investigations shed light on the complex media usage while providing valuable insights for businesses aiming to effectively leverage.

Since the WTO Appellate Body "suspension" crisis, how to reform the Appellate Body has become a hot topic among member states. Especially after the official "suspension" of the Appellate Body, member states have put forward proposals to reform the Appellate Body, but these proposals have failed to achieve substantive results, and the reform of the Appellate Body has been stalled. Therefore, analyzing and studying the reform of the WTO Appellate Body is conducive to promoting the reform of the Appellate Body, getting rid of the crisis of the Appellate Body, and also has positive significance to the reform of the WTO dispute settlement system. The three parts of this article are as follows: the first part studies the WTO Appellate Body's fundamental procedures and gives a general overview of the body to lay the theoretical foundation for the subsequent investigation of the WTO Appellate Body's issues; The second portion examines the legal ramifications of the WTO suspension conundrum. The more divisive practical matters, such as overtime hearings, confusing hearing scope, and the influence of Appellate Body decisions on precedent; The third section of the WTO Appellate Body Reform Suggestions includes suggestions from WTO members regarding current trends in the reform, academic theory surrounding the reform, Appellate Body cases, and reform of the practice of combining future reform of the WTO-specific measures.

With the passage of time and the promotion of global eco-environmental protection concepts, the issue of the climate crisis has attracted the attention of all countries in the world and has become a hot topic characterized by ties. In recent years, major economies have announced their participation in carbon neutral activities one after another, actively implemented the carbon neutral targets, promoted international exchanges based on the concept of green and low carbon, deepened the degree of greening cooperation among countries, and met the needs of carbon neutral policy implementation from a strategic perspective. In the process of popularizing the concept of carbon neutrality, global economies have been able to participate in ecological and environmental protection activities together. Nowadays, there are certain changes in the global development pattern, and a scientific and technological revolution oriented to the goal of carbon neutrality has quietly arrived, and the world energy governance order has also changed. This paper analyzes the trend of the world economy in the context of carbon neutrality and the challenges of cooperation brought about by it, and puts forward the idea of participation in international cooperation from China's standpoint.

Option is one of the most basic financial derivatives, and the pricing of option has always been a significant research topic in financial engineering. Reasonable pricing of options is the premise of options to play an important role in the financial market, for avoiding market risks, stabilizing the financial market, sustainable development of the derivatives market has vital practical significance. Monte Carlo Simulation is an important simulation method in option pricing and it based on probability theory and mathematical statistics, by simulating the path of asset prices to predict a complete average return and obtain an option price estimate. In this paper, the Monte Carlo simulation is used to make an empirical analysis of China's financial derivative SSE 50 ETF option, and the simulation price is compared with prices simulating by other models, and finally compared with the current price of SSE 50 ETF option. The results show that the SSE 50 ETF call option is recommendable to be bought, and has strong feasibility.

This research delves into the intricate dynamics of stock price movements for Bilibili, a prominent digital platform, post its Initial Public Offering (IPO). Emphasis is placed on evaluating the correlation and predictive power of three main factors, Gross Profit, Advertising Revenue, and Additional Services Revenue, in determining stock prices. Furthermore, the study examines the often-assumed positive relationship between Average Monthly Interactions (AMI) and Gross Profit, questioning the depth and directionality of this relationship. Preliminary findings suggest that while Gross Profit and Advertising Revenue may historically be substantial revenue streams impacting stock prices, revenues from additional services are emerging as significant predictors in the contemporary digital platform valuation landscape. Contrary to conventional belief, high AMI does not always translate to proportional Gross Profit gains. The research presents valuable insights for investors, stakeholders, and digital platform operators, elucidating the multifaceted drivers of stock price movements in the digital age.

In recent years, with the continuous development of the global economy and the deepening of the globalization process, the international trade pattern is undergoing major adjustments. Among them, the trade relationship between China and the US, the two largest economies, has been the focus of attention. However, the recent outbreak of the China-US trade war has brought great uncertainties and challenges to the global economy, and the strategic analysis to solve the China-US trade war is also the core content of this study. We need to explore the possibility and difficulty of appealing to the World Trade Organization, and the possibility and challenge of pursuing bilateral negotiations. In addition, we need to consider third-party arbitration mechanisms in the China-US trade war, with a view to finding effective ways to resolve trade disputes.The purpose of this study is to explore its impact on the two countries and the global economy through an in-depth analysis of the China-US trade war, and to provide references for the resolution of the China-US trade war.

The article aims to verify whether the aging population suppresses the economic consumption level of Chinese residents, depending on the economic situation in China. To diversify the sample, the work searched the situation of expenditure of countries in China. Using daily data over the period 2014-2021, the work estimates the correlation between the elderly dependency ratio and economic consumption through the expenditure approach of GDP and the Hodrick and Prescott Filter model. The work adds cyclical components to the correlation equation, indicating the manner of detrending to test the objective outcome of the GDP index. The work concludes that the GDP index is closely connected with medical insurance fund expenditure, leading to the working population paying more attention to healthcare problems. The level of the elderly dependency ratio depends on the medical insurance fund expenditure､social pension insurance funds, and government health expenditure.

The digital economy, characterized by the use of digital tools and platforms for various economic activities, holds paramount importance in shaping contemporary economies. This work conducts a thorough review of China’s digital economy, focusing on key trends, influential drivers, and their extensive implications. This review begins by examining prevailing trends, encompassing technological advancements and the growth of e-commerce. Subsequently, it delves into the regulatory, innovative, and market forces propelling China’s digital transformation. The implications of China’s digitalization on industries and societal dynamics are also investigated. This review reveals how China’s digital economy is fundamentally reshaping its economic and social landscape. Drawing primarily from evidence in the political, economic, and socio-cultural realms, this work underscores the broad macro-level implications. However, the review provides a limited exploration of certain potentially significant factors, such as environmental considerations and the convergence of digital technologies with other industries and regions. Future research directions should delve deeper into sector-specific digital transformation trends, offering a more focused perspective on the opportunities and challenges emerging from this transformative digitization.

Since 1990, China's securities market has been gradually improved. Domestic and foreign scholars have proposed many theoretically perfect investment models, but not many of them have been applied in practice because the market cannot satisfy the strict assumption conditions of the models. Foreign quantitative investment models are not necessarily effective in the Chinese market. Based on this, this paper takes the portfolio theory as a guide, uses the scoring method to construct a multi-factor stock selection model, and selects the relevant factors in combination with the characteristics of the Chinese market. Through empirical analyses, the validity of the multi-factor stock selection model with equal weight allocation in China's market is verified. In addition, this paper innovatively constructs an investor sentiment factor, combines the sentiment timing with the multi-factor stock selection model, optimises the timing on the basis of the multi-factor stock selection model, and proposes an investment strategy to obtain excess returns stably.

Nowadays, more and more enterprises pay attention to the human resource management department, precisely because the importance of human resources cannot be overstated. With it, companies can not only improve their competitiveness and move from resource optimisation to revenue maximisation, but also people are the key productive force of an enterprise. However, for the real meaning of human resources active practice in existing enterprises still have problems. Therefore, the thesis is exploring human resource management and employee development to reflect the impact on organisational performance through four main components: recruitment and selection, training and development, performance appraisal and incentives, employee benefits and satisfaction. And it gives four measures suggestions. Through the investigation and research of the existing literature, with summarizing and concluding, eventually, the study found that scientific and effective human resources bring the rational allocation of resources, the strength of the enterprise's talent pool, and a reasonable salary evaluation system.
