Green innovations are the most critical factor in promoting environmental sustainability worldwide. Trade can speed up the adoption of green innovations by facilitating the transfer of information, skills, and technology. However, trade policy uncertainty can create significant challenges for businesses investing in eco-innovations, leading to increased risk, reduced investment, and slower progress toward sustainable technologies. Recently, a growing number of researchers have shown their interest in finding the factors that can impact green innovations, but none have investigated the influence of trade policy uncertainty on green innovations in the USA and China. In addition, none of the past studies has relied on the nonlinear assumption. This analysis fills these gaps by examining the nonlinear impacts of trade policy uncertainty on eco-innovations in China and the USA over 2000Q1–2021Q4 by employing a nonlinear ARDL model. The finding reveals that a positive shock in trade policy uncertainty results in a decrease in green innovation in the USA and China, while a negative shock in trade policy uncertainty leads to an increase in green innovation in the USA over the long run. The nonlinear models also indicate that a positive shock in trade policy uncertainty harms green innovation in both the USA and China in the short run. The robustness of these results is confirmed by the NQARDL model, which confirms that an upsurge in trade policy uncertainty lowers green innovation in most quantiles in the USA and China in the short and long run. Conversely, negative shocks in trade policy uncertainty stimulate green innovation at most quantiles in both China and the USA, in the short and long run. Thus, policymakers need to consider the potential impact of trade policies on eco-innovations and work to create stable and predictable trade environments that support the growth of renewable technologies and other sustainable solutions.

The research focuses on and analyses the effect of government investment on income distribution by evaluating the effects of public spending on income variation in various fields, in various regions, and at different income levels in the Chinese economy. The study found that government investment in different fields substantially decreases income inequality. Increasing housing security, medical, agriculture, forestry and other expenditures has a significant impact on improving the income inequality between rural and urban inhabitants; the impact of government investment in the western, central, and eastern regions on the reduction of income variation is decreasing successively, with emphasis on government investment in the western and central regions. The effects of government investment on the decline of the income distribution are twofold: first, it influences the amount of low- and middle-income groups; second, it has an impact on the reduction of high-income organizations; however, the impact on the income equality of high-income and low-income organizations is not considerable. In investment, the study demonstrates that income inequality can be reduced without negatively affecting the financial status of higher-income individuals. It is significant to value providing adequate housing security for low-income populations as a critical policy implication. This study, utilizing novel indicators, contributes to the current body of research on the impact of fiscal policy in addressing income inequality in China.

培育德智体美劳全面发展的社会主义建设者和接班人是高校立德树人的目标要求.在新时代新征程的时代背景下,高校被赋予了培育有理想、敢担当、能吃苦、肯奋斗的时代好青年的新任务.然而,在新时代贯彻落实高校立德树人根本任务时,高校依然面临教育理念有待改进、学生理想信念受到冲击、课程育人和校园文化育人效果仍需增强等现实困境.为了进一步贯彻落实高校立德树人的根本任务,新时代高校需要从建设高质量的立德树人教育体系以推进中国式教育现代化进程、强化马克思主义科学理论学习以推进马克思主义信仰教育、推进课程育人的守正创新以不断完善课程育人体系建设、加强校园文化建设以为环境育人赋能等路径出发,培育更多能担当大任的高素质人才.

In order to reduce environmental deterioration and promote sustainable growth, green innovation-which includes ecologically friendly technology and practices-has become a top priority of policymakers worldwide. This research investigates how formal and informal finance affects green innovation in highly polluted high, middle-, and low-income economies, using data spanning from 2007 to 2021. For analyzing the empirical link between formal finance, informal finance, and green innovation, we have employed the 2SLS and GMM estimation techniques. The primary estimates of the analysis suggest that formal and informal funding methods significantly impact environment-related technologies in high-income and middle- and low-income nations. Moreover, the GDP, carbon emissions, trade openness, human capital, research and development, financial stability, and digital finance are essential factors in promoting environment-related technologies in high-, middle-, and low-income nations, respectively. The policymakers in both groups of countries should foster collaboration between the formal and informal sectors to promote green innovations, which is essential for achieving sustainable development goals.

Based on the perspective of people-centred, accelerating the equalization of old-aged services for urban and rural residents in China is of great significance to strengthen the rural old-age service guarantee and promote the development of the old-age service industry and realize social fairness and justice and realize the all-round development of human beings. The problems of equalization of rural and urban old-age services in China are mainly reflected in the following aspects: the level of development of rural and urban oldage services is quite different, and the structural problems of rural residents' provision of old-age services are prominent, and urban and rural residents old-aged services equalization security system is not yet perfect and so on. The difference of urban and rural system, the intensity and scale of financial transfer payment, the level of rural economic development and the demand of rural residents' old-age service are the main factors affecting the equalization of urban and rural residents' pension services. Therefore, it is necessary to accelerate the equalization of old-aged services between urban and rural residents from the aspects of establishing the operational mechanism of old-aged services with the participation of multiple subjects and the new old-age service security system shared by the masses, and promoting the old-age model of combining medical care and support.
