An increase in a currency internationalization levels can positively impact its credibility in international economic activities, and expand the effective demand and optimize the supply structure for the country’s financial service trade. In this way, a state can improve its financial service trade competitiveness in the international market. This study builds a vector autoregressive model based on time-series data of China-US financial services trade from 2010 to 2021, analyzes the impact of different quantitative indicators of RMB internationalization on this trade from the impulse response results, and validates the conclusions using various inspection methods. The results show that the increase in RMB internationalization helps to narrow the China-US financial services trade balance, but with a significant lag. And this effect is heterogeneous in different dimensions, demonstrated by the fact that the development of overseas RMB securities business is more important for the level of RMB internationalization to narrow the China-US financial services trade balance. Finally, among the specific measures to improve its financial services trade, China should focus on developing the international competitiveness of the traditional RMB deposit and loan financial sector, while the competition in the overseas market for high value-added financial businesses must also not be neglected. Furthermore, China needs to implement more targeted RMB internationalization development policies at different levels in the future to provide high-quality financial services to the rest of the world and aid in the economic recovery of the world in the "post-pandemic" era.

Poverty remains a significant global challenge, particularly in severely impoverished areas where balancing eco-civilization and economic growth is crucial. This study aims to analyze livelihood assets, determine appropriate strategies, and establish an eco-compensation model based on ecological vulnerability in Longnan City. We developed a livelihood evaluation index system using the Sustainable Livelihoods Framework and entropy weight method to assess the vulnerable portfolio of livelihood assets. We examined poverty causes and proposed targeted alleviation measures. Additionally, we created an “Eco-Compensation Model of Longnan City” incorporating the Sloping Land Conversion Program, key industries exit compensation, and cross-provincial water compensation based on incentive and punitive mechanisms. Our findings reveal that severely impoverished areas in Longnan City are primarily in the central, southern, and northwestern regions. Poverty is driven by unfavorable natural conditions, frequent natural disasters, regional economic marginalization, inadequate infrastructure, and a limited agricultural structure. The evaluation shows that natural capital in the five areas is lower than the national average level. We propose targeted measures for different vulnerable livelihood portfolios. The eco-compensation model provides a scientifically calculated compensation standard, offering a crucial funding source for implementing targeted poverty alleviation strategies.

<abstract> <p>We investigated the relationship between changes in housing prices and marriage patterns among Chinese residents, considering the evolving real estate market and increasing prevalence of homogamous marriages. Using microdata from the China Household Income Project (CHIP) and urban housing price data, our results showed the following: First, housing price levels significantly decreased the likelihood of residents engaging in hypergamous mating and marrying individuals from lower social strata. Second, regional fluctuations in housing prices could influence residents' marital matches by affecting the spatial distribution of genders. Specifically, the higher the level of urban house prices, the greater the crowding out effect on marriageable men, and the less likely men in that area were to match downwards and marry women from lower social classes. Third, heterogeneity analysis indicated that residents in the eastern regions, younger populations, and migrants faced greater housing price pressures in the process of marital matching, resulting in a more substantial impact on these groups. The study contributes to marriage matching theories and offers policy insights for real estate reforms.</p> </abstract>
