Climate change is increasing the risks of weather-related disasters in many regions around the world. This has an adverse socio-economic impact on households, farmers and small businesses. Some strategies for effectively managing climate related disasters include index based insurance products, which are increasingly offered as alternatives to traditional insurance, particularly in low-income countries. However, the uptake of index insurance remains low, which can be partially attributed to the inherent problem of basis risk. This review assesses the problem of

本文基于互联网企业价值评估的背景，重点探讨一种常用估值方法——相对估值法（Relative Valuation），并以阿里巴巴集团（Alibaba）为实证对象首先，文章回顾了互联网企业估值的特殊性与挑战；其次，介绍了相对估值法的理论基础、常用指标（如市盈率P/E、市净率P/B、市销率P/S、EV/EBITDA 等）及其优缺点；再次，从互联网企业特征出发，分析该方法在阿里巴巴所处环境中的适用性及限制。然后，结合阿里巴巴最新财报数据（截至FY 2024 期）整理公司基本资料、选取可比公司、计算关键估值指标，进而得出对阿里巴巴的估值区间与市场价值对比。最后，基于实证结果，从估值结果合理性、影响因素（如业务结构、成长预期、市场情绪）以及方法优化建议三个维度展开讨论。研究发现：对于快速成长、业务多元的互联网企业而言，虽相对估值法具备便捷性与可比性优势，但也易受到可比公司选取不当、成长预期偏差及无形资产难以量化等影响。论文建议在实际应用中，应辅以折现模型（DCF）等方法，并注意调整估值倍率以反映公司成长性与风险特征。本文的研究可为互联网企业估值提供一种实务参考，也为资产评估的教学与研究提供新的案例视角。

Background: How to cope with the rapid growth of LTC (long-term care) needs for the old people without activities of daily living (ADL), which is also a serious hazard caused by public health emergencies such as COVID-2019 and SARS (2003), has become an urgent task in China, Germany, Japan, and other aging countries. As a response, the LTCI (longterm care insurance) system has been executed among European countries and piloted in 15 cities of China in 2016. Subsequently, the influence and dilemma of LTCI system have become a hot academic topic in the past 20 years.Methods: The review was carried out to reveal the effects of the LTCI system on different economic entities by reviewing relevantliterature published from January 2008 to September 2019. The quality of 25 quantitative and 24 qualitative articles was evaluated using the JBI and CASP critical evaluation checklist, respectively. Results: The review systematically examines the effects of the LTCI system on different microeconomic entities such as caretakers or their families and macroeconomic entities such as government spending. The results show that the LTCI system has a great impact on social welfare. For example, LTCI has a positive effect on the health and life quality of the disabled elderly. However, the role of LTCI in alleviating the financial burden on families with the disabled elderly may be limited. Conclusion: Implementation of LTCI system not only in reducing the physical and mental health problems of health care recipients and providers, and the economic burden of their families, but also promote the development of health care service industry and further improvement of the health care system. However, the dilemma and sustainable development of the LTCI system is the government needs to focus on in the future due to the sustainability of its funding sources.

We examine the effects of issuing green bond on green premium and green signal transmission by matching green bonds with ordinary bonds. We find that the credit spread of green bonds is significantly lower than that of ordinary bonds, especially for those green bonds with lower information disclosure complexity. Besides, issuing green bonds cannot receive a positive response from the stock market, but can significantly reduce issuer’s loan costs and provide more financial subsidies for high polluting issuers. Furthermore, by obtaining discounted loans and financial subsidies, issuing green bonds can increase issuer’s R&D intensity and reduce their carbon emissions. These findings indicate that issuing green bonds can reduce financing costs and convey green signals to market stakeholders with less investment experience.

本文聚焦渐进式延迟退休政策对城镇职工基本养老保险的影响，采用精算平衡模型法，以2024年官方数据为基期，对比基准情景（无延迟退休）与政策情景的基金运行差异。研究发现，该政策通过延长缴费年限、扩大参保基数实现基金增收，通过减少退休领取人数放缓支出增速，显著改善基金财务状况：2030年、2035年、2040年政策情景较基准情景分别多结余2.4万亿元、3.9万亿元、14.1万亿元，基金可持续年限延长。研究证实，渐进式延迟退休能有效抵御人口老龄化冲击，为养老保险制度改革提供缓冲期。

云南省作为我国地震灾害最严重的地区之一，其巨灾保险制度建设对防灾减灾和经济社会可持续发展具有重要意义。本文基于云南省 2015 年以来的地震巨灾保险试点实践，系统梳理了试点探索、初期实践与模式升级三个阶段的发展历程，总结出制度碎片化、财政依赖与基差风险三大核心问题。研究发现，试点制度存在时空覆盖失衡与短期化运作的可持续性困境，财政主导模式抑制了市场需求，指数保险的基差风险问题导致保障有效性不足。针对上述问题，本文提出构建“多支柱、多层次、可持续”的地震巨灾风险共治体系，通过差异化产品设计、需求侧改革与数据驱动技术赋能，推动政府、市场与社会协同治理。研究结论为边疆多民族地区巨灾保险制度创新提供了理论框架与实践路径，对完善国家巨灾风险管理体系具有重要参考价值。

We investigate whether a firm’s decision on green bond issuances is influenced by the green bond issuances by other firms in the same industry. We find that a firm is significantly more likely to issue green bonds after observing that other firms in the same industry have previously issued green bonds. This effect cannot be explained by the issuer’s supplement to their previous issuances, incentive policies, and industry competition. Furthermore, we show that issuing green bonds can bring significant positive stock excess returns, which increases the motivation for institutional investors to learn and drive other firms in the same industry they hold to issue green bonds. Our findings indicate that the peer effect can be driven by social learning of the common ownership among firms and explain the reason for the rapid increase in green bond issuance.

This study investigates the influence of smart supply chain management on the Environmental, Social, and Governance (ESG) performance of Chinese manufacturing firms spanning from 2009 to 2022. Our findings reveal a positive association between smart supply chain management and enhanced ESG performance, a relationship consistently upheld across various analytical methodologies. Additionally, we uncover that smart supply chain practices stimulate corporate social responsibility (CSR) disclosure, contributing to heightened transparency and subsequently bolstering ESG metrics within firms. Furthermore, our analysis demonstrates that the positive effect of smart supply chain management on ESG outcomes is particularly pronounced among firms that are operating in less competitive and more environmentally impactful industries, receiving heightened media scrutiny, and influenced by Confucian principles. This research provides actionable insights for firms seeking to advance their ESG initiatives.

Copper resources are widely used in power networks and clean - energy tech like PV panels, wind turbines, and NEVs. Restricted by domestic resources, China's copper supply chain is vulnerable with risks. Based on six supply - chain stages, this paper builds an assessment system for China's copper supply - chain risks. By adopting an improved Benefit of Doubt (BOD) model, this paper has systematically evaluated the risks in the whole copper supply chain, revealing the trends and deep-rooted causes of these risks. The findings of this study reveal that: (1) The supply chain risk of China's copper resources presents a significant upward trend over the past 15 years; (2) The current supply chain risks in copper are mainly concentrated at the stages of import, production, and application; and the recycling risk has a great potential for reducing the copper supply chain risks in the future. Based on these findings, this paper proposes two policy recommendations: (1) Develop diversified channels for importing copper resources and optimize overseas investment patterns and; (2) Improve the domestic supply capacity of secondary copper resources and reduce the risks at the recycling stage.
