We propose a novel dual-screening classification framework for fund selection designed to align statistical objectives with investor goals. Testing on the Chinese mutual funds market, a Gradient Boosting model implementing our framework generates a statistically and economically significant 14.65% annual risk-adjusted alpha, substantially outperforming identical models trained under a standard regression framework. Feature importance analysis confirms that fund-level momentum and flows are the most significant predictors of performance in this market. Our findings provide a robust and practical framework for active management, demonstrating that modelling both upside potential and downside risk is critical for superior performance.

在保险决策的全过程中，语言扮演着不可或缺的角色。从保险产品的条款说明、销售人员的口头推介，到广告宣传、客服沟通，语言不仅是信息传递的载体，更是塑造消费者认知、触发情感反应、引导决策行为的关键媒介。然而，传统保险研究对语言因素的关注明显不足，往往将语言视为中性的信息通道，忽视了语言本身的特性及其对心理偏差的调节作用。本章将从语言学和口语传播学的视角出发，系统探讨保险沟通中的语言机制及其对保险决策的影响，揭示语言如何放大或缓解消费者的心理偏差，并为后续行为干预提供新的思路。

传统保险经济学基于理性人假设，认为保险消费者能够做出符合自身利益最大化的理性决策。然而，大量现实观察与实证研究表明，保险决策中存在诸多系统性偏差，这些偏差无法用传统理论解释。本研究从行为保险学视角出发，系统探讨保险决策中的主要心理偏差及其形成机制，并在此基础上构建行为干预的理论框架与实施路径。研究发现，保险决策中的心理偏差可分为认知偏差（如可得性启发、代表性启发、锚定效应）、情感偏差（如损失厌恶、模糊厌恶、后悔厌恶）和社会偏差（如从众行为、羊群效应）三类，这些偏差通过影响风险感知、概率判断和效用评估等环节，导致投保不足、过度投保、产品选择错误、续保率低等市场失灵现象。研究进一步提出，行为干预应从供给端（产品设计优化、信息披露改革、默认选项设置）、需求端（保险素养教育、决策辅助工具、反馈机制设计）和监管端（行为洞察应用、消费者保护强化、干预效果评估）三个维度系统推进。本研究为优化保险市场运行、提升消费者福祉、完善保险监管提供了行为科学视角的理论支撑与实践参考。

人口老龄化引发的健康保障需求升级，推动保险行业进入供给侧创新深水区。本文以癌症复发险为研究载体，系统分析老龄化社会下保险产品创新的逻辑起点、实践路径与风险管控机制。通过对主流癌症复发险产品进行深度案例分析，研究发现：当前市场已形成覆盖30种常见恶性肿瘤的产品体系，核保实现数据风控与基于分期、分型、治疗预后的精细化风险分层；癌症复发险通过病种扩容、保障责任模块化与“保险+健康”服务模式创新，有效填补了带病体保障缺口，在基本医保基础上织密了多层次医疗保障网络。然而，产品发展仍面临逆选择风险、医疗数据壁垒、盈利平衡难题以及复发、特药目录等核心条款定义缺乏行业统一规范等核心挑战。本文构建“技术赋能风控+政策协同监管+跨行业生态共建”的三维风险管理体系，结合日本、美国等国际经验的本土化适配，提出推动两核风控动态迭代、建立行业标准、深化医疗机构服务直连等优化路径。研究为养老金融创新与风险治理提供了微观产品层面的实证参考，对完善多层次社会保障体系具有重要实践意义。

在人口老龄化加速与银发经济蓬勃发展的双重背景下，老年体育健康消费已成为扩大内需、促进健康老龄化的重要抓手，但随之而来的财务欺诈、健康安全隐患、市场失序及技术风险等问题日益凸显，风险治理滞后于市场发展。本研究基于风险管理视角，系统探讨银发群体体育健康消费的驱动因素与风险防控机制。研究首先梳理银发经济、体育健康消费及老年消费风险管理的文献进展，构建"驱动因素—风险识别—治理优化"的分析框架；其次，剖析当前老年体育健康消费的主要形态及其面临的消费观念局限、市场供给不足与适老化设计欠缺等结构性问题，重点揭示预付式消费资金风险、保健品虚假宣传、运动伤害责任认定模糊及智能技术数据安全等四类核心风险；再次，从社会文化、经济保障、技术赋能与心理需求四个维度解析消费驱动因素，并针对性提出财务、健康安全、市场与技术风险的识别标准及管理策略；最后，从政策规制、市场创新、社会协同三个层面设计优化路径，并以山东省"体育+"多元消费场景与预付式消费监管实践为例，验证风险治理机制的有效性。研究表明，老年体育健康消费的可持续发展需实现从"规模扩张"向"质量与风险并重"的转型，通过构建政府监管、市场自律、社会参与、家庭支持的四维风险共治体系，为银发经济高质量发展提供安全保障。本研究丰富了银发经济风险管理的理论视角，为老年消费安全保障与体育市场规范发展提供实践参考。

我国农村人口老龄化呈现出深度、叠加的特征，养老服务碰到机构供需失配、专业力量缺失、支付能力不佳的结构性困境，凭借农村“熟人社会”的互助养老模式成了破解难题的有效法子，本文借助“乡土智慧赋能 + 现代治理提质”双重视角来研究，把浙闽“祠堂养老”和陕甘“院落互助”典型模式作为样本，全面整理农村互助养老供应链的发展基础，和现存的供需不契合、主体协同有障碍、治理机制不健全、可持续性动力不足等困境，解析“熟人社会”逻辑在养老服务供应链当中的重构路径及运作机制，钻研典型模式的优点和弊端，进而从治理机制、供需匹配度、政府帮扶、乡土养老文化四个角度，提出使乡土智慧和现代治理融合的农村互助养老供应链实践做法，为促使农村养老服务高质量进步提供理论支撑及实践办法。

We construct the China Crude Oil Volatility Index (CNOVX)—the first model-free, optionimplied measure of forward-looking oil price risk for China—using INE crude oil options from 2021 to 2024 and an adapted CBOE methodology that accounts for sparse strike availability via smooth interpolation and extrapolation. Our results show that CNOVX increases with trading activity in the futures market, declines with option volume, and is strongly predicted by the 30-day realized variance of the SC crude oil futures contract. External shocks, including the Russia–Ukraine conflict and the Geopolitical Risk Index, significantly elevate CNOVX levels. During the COVID-19 pandemic, mortality risk intensifies the volatility-amplifying role of futures trading and strengthens the volatility-dampening effect of options, while confirmed case counts have weaker influence. We further document a pronounced asymmetric leverage effect: negative futures returns raise CNOVX more than positive returns of equal size. However, volatility feedback effects are negligible, as changes in implied volatility respond primarily to contemporaneous market conditions. Overall, CNOVX serves as a timely and informative benchmark for monitoring risk in China’s evolving crude oil derivatives market, with valuable implications for investors, hedgers, and policymakers.

The Fibonacci sequence is created by the recurrence of Fn = Fn−1 + Fn−2 ( n ≥ 2; F0 = 0; F1=1) from which the nearly 38.2% or 61.8% is derived for revenue increase or decrease. It has been increasingly and widely studied in research on options market trading. The high volatility of the options market makes the option premium greatly affected by the growing emotional involvement of buyers and sellers before the position is closed. The efficient affective computing and measures may provide traders a rough guide to working out the route to a profit. Based on the practical application of Fibonacci-like sequence and affective computing of option trading data in China SSE (Shanghai Stock Exchange) 50ETF options, we concluded that profit statistically changes around 38.2% or 61.8% increase line once call options flood in the market and bring the rapid price acceleration. On the contrary, 38.2% or 61.8% is considered another temporary decrease line when the price quickly falls from the balance point of price under the influence of huge put options. The mixed emotions of greed and fear make the option premium commonly fluctuate in cycles. The Fibonacci-like wavelet analysis is only one of the options volatility strategies, and it does not change the nature of market uncertainty.

February 9, 2025 marks the 10th anniversary of the establishment of China's ETF options market. To celebrate this anniversary, China will open the ETF options market to qualified foreign investors on October 9, 2025. This is both an opportunity and a challenge. This is the first time in a decade that China has decided to open its ETF options market. The challenge is that foreign investors will face competition from China's 1.08 million options investors. This article will discuss the basic rules and requirements for options trading in China. In addition, we will introduce the application of Confusion Quotient sentiment index in options trading, and analyze how options contract premiums fluctuated significantly after the Fed cut interest rates by 50 basis points on September 18, 2024. Within a month, the Fed's interest rate cut triggered a sharp rise in call options contracts in China's options market, with a maximum profit of 3507.32%, and put option contracts suffered huge losses, with a maximum loss of 99.91%. Our findings prove that China's ETF options market is highly volatile, presenting both opportunities and challenges for foreign investors. Options trading is a double-edged sword, and you need to be cautious when entering the market.
