As China transitions from high-speed to high-quality economic development, the concept of sustainable development, particularly environmental, social, and governance (ESG), has emerged as a crucial consideration in corporate decision-making. This study examines the relationship between ESG performance and corporate resilience through the lens of capital allocation efficiency. Employing a fixed-effects model, heterogeneity analysis, and a mediation effect model, we analyzed 4436 A-share listed companies that were rated according to ESG standards by the China Securities Index (CSI) between 2011 and 2021. Our findings suggest that: (1) ESG performance positively impacts corporate resilience. (2) The magnitude of this effect varies based on the ownership structure and industry. Specifically, ESG performance has a more significant influence on non-state-owned companies and manufacturing companies. (3) Improving ESG performance can enhance corporate resilience through three mechanisms: reducing financing costs, improving investment efficiency, and improving operational efficiency.

The presence of a link between corporate environmental protection investment and firm value is essential for enterprises to have incentives to invest in environmental protection by themselves. How environmental information disclosure affects the relationship between environmental protection investment and firm value is also an issue worth exploring. This paper uses the regression model with the industry and time-fixed effects to examine the relationship between environmental protection investment and firm value of China’s A-share heavily and non-heavily polluting enterprises from 2010–2020, as well as the moderating role of environmental information disclosure. The empirical results show that (1) there is a significant U-shaped relationship between environmental protection investment and firm value, and (2) corporate environmental information disclosure has a moderating effect. Specifically, it has an “amplifying” effect on the relationship between environmental protection investment and firm value. If a company’s environmental protection investment is insufficient, overly transparent corporate environmental disclosure will exacerbate the decline in firm value. Once environmental protection investment is up to standard, adequate disclosure can contribute to an increase in firm value.

Polyphenols are a diverse group of plant-derived bioactives that have been investigated as multi-target candidates for the potential prevention and management of neurodegenerative diseases (NDDs). We conducted an integrated bibliometric and mechanistic scoping review covering 12 polyphenol classes and seven major NDDs using records from PubMed, Embase, the Cochrane Library, and Web of Science (1940–2024). Research landscapes and emerging themes were mapped using keyword co-occurrence, clustering analyses, and BERTopic modeling. Mechanistic evidence was synthesized across core pathways, including oxidative stress, neuroinflammation, proteostasis (amyloid/tau and α-synuclein), mitochondrial dysfunction, and cholinergic modulation, to link preclinical findings with clinical outcomes. Publication output increased markedly after 2000, with China and the United States contributing the most records. Four persistent hotspots were identified: (1) antioxidant and neuroprotective effects (e.g., resveratrol, curcumin); (2) anti-inflammatory activity and intracellular signaling; (3) cognition, aging, and sex-specific responses in clinical research; and (4) animal models of memory impairment. Clinically investigated interventions include epigallocatechin gallate, Ginkgo biloba extracts, olive/cocoa polyphenols, and flavonoid-rich mixtures; however, limited bioavailability and heterogeneous trial designs constrain the strength of effect estimates. Advances in delivery systems, computational screening, and precision nutrition may improve translation. Overall, polyphenols show multi-target neuroprotective potential, but larger and more standardized clinical trials are needed to support evidence-based nutritional strategies for NDD prevention and management.

In the background of the green transformation of the economy and society, the ESG performance of enterprises has been paid more and more attention in the investment decision-making. However, previous studies have inadequately explored how the ESG performance affects corporate financing costs. Based on the information asymmetry theory, this paper analyzes the impact mechanism of ESG performance on corporate financing costs. Then, taking 1044 A-share listed companies in 2016–2020 as a sample, through the sorting and analysis of ESG report disclosure and rating data, the company's ESG performance indicators are obtained, and an empirical model is built to test the relationship between ESG performance and corporate financing costs. This paper constructs a panel regression model using ESG rating data and corporate financial data and finds that in the overall sample, the higher the ESG performance, the lower the equity financing cost; The higher the ESG performance, the lower the debt financing cost. In addition, it also discussed the moderating effect of enterprise scale and media attention on the impact of ESG performance on enterprise financing costs. The empirical results show that the influence of company size on ESG performance on financing costs has a moderating effect and a positive moderating effect.
