The policy of ethnic equality and solidarity aims to narrow the ethnic gap and develop harmoniously. At the level of higher education, it should promote the equity of ethnic education. This paper uses the administrative data of undergraduate students from 2008 to 2015 in a liberal arts university in southwest China to study the differences, causes and dynamic trends in the scores of college students from different nationalities. The results show that compared with Han students, the average GPA of ethnic minority students is 0.13 points lower (equivalent to 0.23 and 0.3 standard deviations of the scores of ethnic minority and Han students), the fourth grade scores are 0.28 standard deviations lower, and 7.3% lower. This difference is more significant in the western region, especially in Xinjiang, Yunnan, Hubei and other provinces inhabited by ethnic minorities; Kazak and uygur are the nationalities with the biggest gap with han students; The difference between girls is more significant than that between boys. The "peer effect" and cultural distance between roommates are important reasons for this difference. Further analysis shows that although the ethnic differences in academic performance are gradually expanding, the growth rate tends to converge. The above conclusions are helpful to clarify the object and time of making national higher education policy, and also have important reference significance for primary and secondary education.

Green innovation, as a sustainable development approach, can synergistically promote high-quality economic and social development. We select China's A-share-listed manufacturing corporations from 2011 to 2021 as the research sample to empirically study the impact of executive academic experience on green innovation in manufacturing corporations. Further, we test the relationship between executive academic experience and green innovation in manufacturing corporations under the mediating role of corporate social responsibility and the moderating role of heterogeneous environmental regulations. The study shows that (1) executive academic experience helps to promote green innovation in manufacturing corporations; (2) executive academic experience is conducive to promoting the fulfillment of social responsibility by manufacturing corporations; (3) corporate social responsibility plays a mediating role between executive academic experience and green innovation in manufacturing corporations; (4) environmental regulation positively moderates the relationship between executive academic experience and green innovation in manufacturing corporations, and both formal environmental regulation and informal environmental regulation positively moderated the promotion of green innovation in manufacturing corporations by executive academic experience.

The signing of RCEP has created new opportunities for the development of China's export trade, and international logistics capacity is an important factor affecting the conduct of international trade. This paper qualitatively describes and analyzes the LPI index and its sub-indicators of RCEP member countries, and empirically investigates the impact of logistics performance level on China's export trade through an extended gravity model. The study shows that there are large differences in logistics performance levels among RCEP member countries, especially in South Asia, where the quality of logistics infrastructure and customs efficiency are the most lagging behind, which are the key factors pulling down the logistics performance index; the signing of RCEP has effectively promoted China's foreign trade level, but there are great differences in export amounts to different countries, and the logistics performance levels of importing countries and China's export trade are significant positive correlation, the improvement of logistics performance is conducive to promoting China's export trade to RCEP member countries, and from the viewpoint of logistics links, the role of logistics infrastructure quality is the strongest, and the influence of cargo transportation timeliness is the weakest.

Based on the behavioral theory of the firm, we investigate the impact of performance negative feedback on R&D efficiency. The results show that when performance falls below aspirations, firms pay more attention to R&D projects with high R&D efficiency to get rid of the operating pressure, reputation pressure and resource constraints caused by the decline in performance. This effect may be influenced by institutional differences. In the case of negative feedback, a good regional institutional environment is conducive to the improvement of R&D efficiency, while a weak regional institutional environment weakens this effect. Specifically, the higher the degree of IPR enforcement and financial market development, as well as the lower the degree of local government intervention, the more inclined firms are to increase R&D efficiency. The findings provide insights into understanding R&D efficiency improvement in the context of emerging markets.

Risk management strategies protect the company as a whole as well as employees from unexpected financial impacts. As is the case in personal finance, preparing for certain scenarios helps confront any difficulties the company may face and allows it to get out of this predicament. For any project to be successful, it must be determined how the agency implementing the project will deal with potential risks so that it can identify, mitigate or avoid problems when it needs to do so. Successful project managers realize the importance of risk management, because achieving project objectives depends on planning, preparation, results and evaluation that contribute to achieving strategic objectives, especially sustainable development of communities. To ensure the success of your project, determine how you will handle potential risks so that you can identify, mitigate, or avoid problems when you need to do so.

This study investigates the impact of inventor CEOs on firm performance using a manually collected database of firms' inventors. Our findings reveal that, on average, firms with inventor CEOs experience a one- and two-percentage-point increase in ROA and ROE, respectively, compared to firms with noninventor CEOs. To address potential endogeneity issues, we employ turnover analysis, an instrumental variable approach, and propensity score matching. The estimation results suggest that inventor CEOs significantly enhance firm performance by fostering innovation and total factor productivity. This research contributes novel evidence on the relationship between inventor CEOs and firm performance.

Industrial policy is the government’s guidance and intervention in industrial development to achieve economic and social goals, and it seeks to steer the direction of industrial development, facilitate industrial structure upgrades, and improve social welfare. Based on panel data on 31 provinces in China from 2011 to 2022, this study examines the effects of industrial promotion from China’s Five-Year Plans on corporate innovation performance using a difference-in-differences (DID) model. The study findings indicate that industrial promotion from China’s Five-Year Plans promotes corporate innovation performance, and the basic conclusion remains robust when changing how firms’ innovation is measured, removing provincial policy interference, excluding the four municipalities in China, and utilizing the PSM-DID model. Moreover, this paper explores how industrial promotion influences firms’ innovation performance. The mechanism analysis reveals that industrial promotion from China’s Five-Year Plans encourages firms’ innovation through tax incentives, government subsidies, and credit support. In addition, heterogeneity tests find that industrial promotion has a more significant effect on corporate innovation among small-scale firms and firms operating in highly competitive industries and regions characterized by high marketization. The empirical findings presented provide evidence for enhancing corporate innovation performance through industry promotion in China’s Five-Year Plans and offer insights that can refine the formulation of Five-Year Plans.

This paper investigates the impact of new quality productivity on corporate innovation, and empirically analyzes it using A-share data from 2012-2022. New quality productivity, which includes emerging industries, future industries and digital transformation of traditional industries, has a significant positive effect on corporate innovation. The study shows that new quality productivity promotes innovation by enhancing innovation incentives and improving ESG performance. Improvements in the institutional environment can enhance its role in promoting innovation. It is recommended to enhance new quality productivity, stimulate innovation in SMEs, focus on ESG performance and develop differentiated strategies to support sustained innovation in corporate technology.

Grain trade plays a critical role in global grain security and the balance of grain supply and demand across countries. As globalization progresses, the complexity and diversity of grain trade have become increasingly prominent. Its significance extends beyond the economic sphere, directly impacting social stability and international relations. The dynamic development of grain trade is influenced by a variety of factors, including climate change, international economic policies, technological advancements, and geopolitics. At the same time, the complexity of global grain supply chains, the uncertainty of international trade policies, and the frequent occurrence of extreme climate events pose significant challenges to the smooth operation of grain trade. In recent years, there has been growing attention in the international community on how to achieve the sustainable development of grain trade by optimizing policies, strengthening international cooperation, and promoting technological innovation. This study systematically reviews the existing literature on grain trade, providing a comprehensive summary of the research landscape, covering factors influencing grain trade, development trends, supply chain management, and risk management. The goal is to provide a systematic analysis and insights for both academics and policymakers, as well as directions and references for future research. Additionally, the study explores how grain trade has maintained resilience amid global crises such as the COVID-19 pandemic and climate change, and offers strategic recommendations for achieving global grain security. This research aims to further promote the sustainable development of grain trade systems and provide strong support for global grain security and socioeconomic stability.

Influenced by traditional notions of solidarity, when a province’s planning can be highly aligned with that of the central government, the province is perceived to be more collective and thus able to receive financial or resource favors from the central government. This consistency, as is often the case, reflected in doing the same thing as the central government. This situation may lead governors to ignore local economic performance and thus reduce regional innovation efficiency, as in the case of China’s Great Leap Forward. Likewise, it is possible to get better resources (energy or capital) by demonstrating managerial submissiveness, thus improving the regional innovation efficiency. Therefore, to verify the relationship between imitative governance and regional innovation efficiency, we collected relevant data from 31 major provincial administrative units in China, calculated the degree of imitative governance between provincial government work reports and central government work reports through text similarity, as well as utilized the SBM-DEA model to evaluate regional innovation efficiency. Meanwhile, we provide a new explanation of the phenomenon from the perspective of resource inclination. Finally, the empirical results show that imitative governance promotes local innovation efficiency and is moderated by resource inclination.
