The global demographic landscape is undergoing significant changes due to increasing life expectancies and declining birth rates, leading to an aging population across many countries. This paper explores the multifaceted causes behind this demographic shift, including healthcare advances, fertility patterns, and improved living conditions. This paper examines the implications of an aging population on economic stability, social structures, and public services. In particular, this paper studies the impact on productivity due to a lack of young population, the pressure on the pension system from the increasing number of the elderly, and the corresponding challenges in the healthcare system. The study also analyzes various policy responses implemented by different nations to address these challenges, focusing on innovative strategies from developed and developing countries. Special attention is given to China's approach, highlighting its pension reforms, healthcare enhancements, and elderly care initiatives. By comparing and contrasting these strategies, this paper aims to offer insights into effective policy frameworks and potential areas for future research in managing the impacts of an aging population.

Nowadays, the influence that caused by the government in the aspect of national economy becomes bigger, especially in the special time period such as epidemic. In this study, I analyzed the several aspects of how does the American government affect the national economy by the method of policy in the COVID-19 period. Since the American government prompted the development of American industry system in 18th century, the government power and effect on the development direction of economy became even larger. In 21st century, American government still controls the economy but much weaker because of the ‘Small Government’ strategy, but in the period of epidemic, the Biden government’s ‘Bidenomic’ chose to back to the ‘Big government’ strategy. Such as controlling the export and import, providing more policy that can restrict the action of business, producing the recuse plan act to help extreme poor people in epidemic. This essay will also illustrate the specific influence of government of the economy in epidemic time, for example, the GDP growth, the investment and consuming, the export and import, and some bad result like inflation.

The VIE structure is a unique structure widely used by Chinese companies, especially in industries with restricted foreign investment. Through this structure, Chinese companies can allow foreign investors to indirectly invest money and receive profits through complex contractual agreements without violating domestic and foreign investment restrictions. The operating mechanism of the VIE structure can bring convenience to Chinese companies, provide them with opportunities to enter the international capital market, help them circumvent foreign investment access restrictions, improve company valuations and market liquidity, and simplify the IPO process. However, the structure also faces many risks, including legal uncertainty, regulatory risks, and tax and information security issues. Given that the VIE structure relies on contracts with uncertain enforceability, which are not recognized in the Chinese legal system, foreign investors face greater legal risks when investing in VIE-structured companies. Through an in-depth analysis of Chinese VIE firms, this article aims to provide a reference for investors and policymakers to better understand its advantages and disadvantages and explore its future development direction.

This paper explores China’s transition from traditional growth drivers, such as manufacturing and investment, to new quality productive forces that emphasize innovation, technological advancement, and sustainability. Against the backdrop of diminishing returns from resource-intensive industries and rising global competition, China has strategically pivoted toward innovation-driven growth as a necessary path for long-term economic resilience. The research focuses on analyzing the role of new quality productive forces in driving this transition, with a particular emphasis on their impact on productivity, industrial upgrading, and sustainable development. Using a combination of qualitative analysis and case studies, this paper examines the technological innovations and policy initiatives that are reshaping China’s economic landscape. The study includes an analysis of sectors such as renewable energy, telecommunications, and electric vehicles to illustrate how these new forces are transforming industries and creating new opportunities. The findings reveal that while the transition presents significant challenges, such as the need for large-scale workforce reskilling and managing technological disruptions, it also offers substantial opportunities for economic growth and global leadership. The study concludes that fostering new quality productive forces is essential for China to maintain its competitive edge in the digital economy and achieve sustainable, long-term growth.

The severity of population aging profoundly impacts social and economic development over time. This paper analyzes some important factors leading to population aging, their social impacts, and development trends summarizes some strategies that may slow down this social phenomenon and demonstrates some factors that may gradually reduce the effect of population aging and the development reasons for these factors. Some aspects that may promote the intensification of population aging and corresponding solutions are proposed to reduce the negative impact. Conclusion Population aging would have negative influence mostly in the future. However, this social phenomenon will also contribute to the development of the society in some totally new developed parts that may lead to the change of economy of the society. Moreover, population aging will also have influence on a country’s culture and politics which might change people’s cognition in the future and the country’s diplomacy with other countries.

This article examines the phenomenon of price volatility in China's new-energy vehicle market and separately analyses the causes and possible consequences in terms of technological innovation and government policies. The Chinese government's policies to promote new energy vehicles, such as subsidies and rapid technological modernisation, have led to high demand for green energy vehicles and a fiercer competitive environment for companies, resulting in a downward price trend in China's new energy vehicle market. Aggressive pricing strategies often come at the expense of profit margins. Continued price declines can lead to fierce competition in China's new energy vehicle market, reducing the living space for small enterprises and reducing the diversity and development potential of the latest energy market. This article identifies the importance of the sustainable development of China's new energy vehicle industry and highlights the need for innovation, differentiation and a stricter policy framework to address the problem of price volatility. The aim is to provide suggestions to the government and the public on how to address the challenges caused by price erosion to promote a healthier and more competitive market environment that drives the growth and technological progress of China's NEV industry.

Modern Monetary Theory (MMT) has become a significant alternative to traditional economic thought, challenging conventional views on fiscal and monetary policy, particularly regarding government debt and deficits. MMT challenges traditional economic frameworks by advocating for the government's sovereign currency-issuing power to achieve full employment and stabilize the economy without necessarily triggering inflation. This paper explores the origins and development of MMT, highlighting key contributions by economists such as L. Randall Wray, Stephanie Kelton, and Warren Mosler. The study examines the application of MMT principles in countries like the United States and Japan, analyzing the outcomes of MMT-like policies during periods of economic crisis. Through a comparative analysis of fiscal and monetary policy, the paper argues that MMT offers a viable framework for achieving economic stability and full employment, though it also raises concerns about inflation and long-term fiscal sustainability. The findings also emphasize the importance of strategic policy integration in a globally interconnected economic landscape. Furthermore, this comprehensive analysis aims to contribute to the broader dialogue on how governments can leverage economic theories like MMT to navigate complex financial environments.

As the global wave of aging accelerates, China has entered a notable phase of moderate aging. This profound demographic shift has not only reshaped the population composition of society but also posed severe challenges to the driving force of economic development and the carrying capacity of the social security system. This paper delves into the intricate and interdependent relationship network among population aging, social security expenditures, and economic growth. The research finds that the aging process directly impacts the potential and speed of economic growth by reducing labor supply and increasing labor costs. Conversely, the strength of economic growth serves as the cornerstone, determining the financial adequacy and sustainability of the social security system, which in turn indirectly influences the welfare protection level for the aging population. Therefore, the core strategy for addressing the challenges of aging lies in stimulating the vitality and potential of economic growth to provide a solid economic foundation for the social security system. Simultaneously, it is necessary to meticulously design social security policies to ensure that expenditures meet the reasonable needs of the elderly population while avoiding excessive fiscal shocks to stability.
