With the acceleration of the global digital transformation process, online international business negotiations have become the main method for multinational enterprises to carry out international cooperation. This study adopts a research method combining literature analysis and questionnaire surveys to systematically analyze the main challenges faced by online international business negotiations and their optimization paths. The study found that current online negotiations mainly face four core challenges: technical obstacles (network stability issues and data security risks), communication efficiency decline (non-verbal signals account for 63.5% of the loss), cultural misinterpretation intensification (communication differences in different cultural backgrounds), and difficulty in establishing trust (the rate of disputes in remote contract signing and performance is 33% higher than offline). To address these issues, this paper proposes a dual-track optimization path of technology-driven (including the application of intelligent tools and infrastructure upgrade plans) and institutional guarantee type (covering optimization measures at the enterprise level and government level). This study not only provides practical guidance for multinational enterprises but also offers theoretical references for the improvement of international digital business negotiation rules.

Against the backdrop of global energy supply being frequently impacted by geopolitical conflicts, extreme climate events, and structural contradictions in energy transition, energy resilience has emerged as a core issue in global governance and energy research. The paper systematically reviews the theoretical evolution trajectory and integrated framework of energy resilience, explores its assessment methods and key indicators, and summarizes the differentiated paths in international practices. The conclusions are drawn as follows: First, energy resilience is not a single static attribute, but a dynamic complex system that requires the intertwining of technology, society, and policies. Second, the diversification of international energy resilience paths primarily stems from the "adaptive choices" made by countries at different stages of development and with varying economic and technical backgrounds. Developed countries rely on the dual drive of "technology + capital" to build energy resilience, while developing countries focus on low-cost and targeted breakthroughs in energy resilience paths. Moreover, the effectiveness of energy resilience does not lie in whether the model is "advanced or not", but in whether it forms a dynamic adaptation with the country's actual conditions and risk characteristics.

In recent years, Chinese producers have been under an imminent great transformation to international trade as conventionally practiced by them owing to constraints with traditional exports and being propelled by new digital platforms. The paper undertakes an investigation of structural transformation from conventional distribution trends to export sales made possible by digital means, assessing challenges as well as benefits that pertain to such transformation. Through leading company cases, this study analyzes how contemporary technologies-such as live-streaming, Augmented Reality/Virtual Reality (AR/VR) product demonstrations, as well as cross-border digital stores-are redefining penetration within markets, efficiency, as well as profitability for Chinese corporations. The investigation also identifies inhibitors that discourage digital adoption, such as digital divide, regulatory risk, as well as cultural divide, as well as prescriptions to countering such inhibitors that are feasible. The results identify a central role for light-weight digital tools, hybrid policy platforms, as well as workshop reconfigurations to underpin a successful transformation.

This study presents the optimum bidding strategy for first, second, third and all pay auctions in this article. Assuming that all bidders are rational, meaning that they would all want to make the most profit and behave the same, and there exists an equilibrium strategy that all bidders use, compute a mathematical model for different types of auctions. First, believe that there exists an equilibrium strategy that the strategy is linear, if not then we would try non-linear equilibrium strategies, it could be any polynomial or even exponential. Solving it, there will be a bid function where bidders get the maximum profit while the probability of winning is high. Next step, calculate the expected revenue for the auctioneer using our results from the equilibrium strategy. They are the same due to the revenue equivalence theorem. It is discovered that under certain conditions, different auction formats yield the same expected revenue for the seller.

The study of bond prices and yield curves is crucial in modern financial markets, as bonds play a significant role in the global economy. Recent market volatility, driven by economic uncertainties and changing interest rate environments, underscores the need for a comprehensive analysis of how yield curve changes impact bond prices. This paper reviews the relationship between the bond price and the change in the yield curves. It explains the basic pricing models and the role of the yield curve, then discusses key drivers of price changes, including interest rate shifts, inflation expectations, and investor sentiment. By using the bond price calculation formula, the analysis shows that yield curve movements influence bond prices through changes in discount rates, while investor behavior and policy expectations can also have various effects on the curve. Lastly, it ends with implications for policymakers and investors, notes the study’s limitations, and provides some suggestions for future research.

During the past few decades, China's economy experienced rapid expansion, foreign trade between China and other countries has also increased. However, numerous countries implement trade barriers to safeguard their domestic industries, and the adoption of green trade barrier policies continues to impede the sustainable development of China's international commerce. This article summarizes the definition, characteristics, and main forms of green trade barriers by sorting out existing documents, and finds that the characteristics mainly include nominal rationality, formal legality, etc., and the main forms are green technology guidelines, green tariff systems, etc. By analyzing the mainstream global literature on how green trade restrictions affect China's international commerce, it is evident that there are two distinct aspects to the way that green trade barriers affect China's international trade. In the final section, this paper organizes the current measures to address the obstacles to green trade and summarizes its future research trends are mainly focused on two aspects: increasing research on green trade barrier policies in nations in Asia and deepening research on its new situation.

In today's new trend of digital economy, digital transformation of enterprises is necessary in order to cope with the changes in the external sales environment as well as to facilitate the sustainable development of enterprises. With machine intelligence, connected devices, and large-scale data analytics as core divers，the digital economy has become a new engine for economic growth in all countries, systematically transforming business models, operational processes, organizational structures, information security and customer experience to improve efficiency, innovate business models and enhance competitiveness. With reference to studies on Small and Medium Enterprises (SMEs) digital transformation across domestic and foreign research，this paper systematically analyzes the core dilemmas faced by enterprises (especially SMEs) in digital transformation, including insufficient technological capabilities, organizational execution barriers, and lack of capital. Through case comparisons and theoretical integration, it proposes a layered path to crack the problem, implementing the transformation in phases, cooperating and sharing resources among enterprises, and relying on policy and financial support, and so on. This study provides systematic references and solutions for enterprises' transformation practices in the age of digital economy, aiming to promote SMEs to accelerate the pace of digital transformation.

With the rapid development of global digital trade, Cross-Border E-Commerce (CBEC) is reshaping the international trade pattern with an average annual growth rate of 20% with its unique business model and technical empowerment. Based on the theoretical framework of value chain, this paper systematically analyzes the alternative impact and co-evolution path of CBEC on traditional foreign trade by combining typical cases such as TikTok live direct selling in Jiangsu Pajama Factory and Anker technology fragmentation order operation in Shenzhen. The research shows that CBEC can reduce the transaction cost by 15%-25% through disintermediation, improve the anti-risk ability by relying on flexible supply chain, and innovate the overseas warehouse mode to reduce the performance limitation to 1/30 of the traditional mode. By building a regional storage center, CBEC can realize the nearest delivery of orders, thus shorten the delivery cycle and optimize the shopping experience of consumers. Promote the transformation of international trade from "chain structure" to "network ecology". Although commodity trade still relies on traditional channels in the short term, in the long run, the integration mode of "mixed batch export + overseas warehouse pre-position" will become the mainstream development direction. This study not only reveals the subversive influence of digital technology on traditional industries but also provides a theoretical basis and practical path for the transformation of China’s manufacturing to "China Zhizao".

In recent years, global environmental challenges have become increasingly severe. To promote the green transformation of the economy, governments and international organizations around the world have explored green finance as a regulatory tool through research and practice. In order to achieve green development, energy conservation and emission reduction, and promote new productive forces, China has put forward increasingly improved green financial market mechanisms and related policies, among which carbon finance is highly representative. How to formulate and developing a carbon finance mechanism that is in line with China's economy, technology, and people's livelihood to achieve the "dual carbon" goals as soon as possible is a research issue of great significance at present. This paper will select carbon finance policies from different developed countries, systematically sort out the development process and existing accomplishments of China’s carbon finance, and review existing literature to summarize the relevant relationships between carbon finance and economic development. energy conservation and emission reduction, etc. Combined with the relevant characteristics of China's economy, it will draw relevant enlightenment with certain reference value.
