双边匹配理论方法广泛应用在各个行业与日常生活中,产生较大的经济价值与社会价值。然而,现实双边匹配决策过程中,决策问题的复杂性使得双方主体给出的偏好信息是模糊的,决策环境的复杂性可能使所给出的偏好信息是不确定的。考虑到现实双边匹配问题的上述特征,给出一种新的犹豫模糊元偏好下的双边匹配决策方法。首先,基于TOPSIS(Technique for Order Preference by Similarity to Ideal Solution)方法将犹豫模糊元矩阵转化为贴近度矩阵,即主体满意度矩阵;接着,构建以双边主体满意度最大化为目标的多目标规划模型;进一步地,运用线性加权法将多目标规划模型转化为单目标规划模型,并求解该模型得到最佳双边匹配方案;最后,使用一个人岗匹配实例验证该模型的有效性与有效性。
随着我国老龄化社会的程度不断加深,积极应对人口老龄化这一人口结构性变化对我国居民消费的影响,有助于支撑内循环良性运作,扩大经济发展内生动力。如何有效满足老年群体多样化、个性化的需求,成为社会发展的重要议题。特别是在乡村振兴的战略背景下,农村地区老年人口比例高、养老服务资源相对匮乏,如何实现精准养老,提升农村老年人的生活质量,是亟待解决的问题。同时,电商平台的快速发展为解决这一问题提供了新思路和手段。本文旨在探讨依托乡村振兴战略,利用电商平台的既有优势创新应用,帮助农村老年群体跨过“数字鸿沟”,通过深入分析电商平台在健康管理、生活照料、情感陪伴和文化休闲等方面的服务潜力,评估其面临的挑战与机遇,从医疗服务、日间照料、社交需求等多方面提升农村地区老年群体生活质量,以期为乡村振兴战略实施提供新的视角和实现路径。With the deepening of aging society in our country, actively coping with the impact of population structural change, aging of population on the residents consumption in our country, can help support sound internal cycle operation and expand endogenous impetus of economic development. How to effectively meet the diverse and personalized needs of the elderly groups has become an important issue in social development. Especially under the strategic background of rural revitalization, the proportion of elderly population in rural areas is high, and the resources of old-age service are relatively scarce. How to achieve precise old-age care and improve the quality of life of rural elderly people is an urgent problem to be solved. At the same time, the rapid development of e-commerce platforms provides new ideas and means to solve this problem. This paper aims to explore how to leverage the advantages of e-commerce platforms and their innovative applications in the context of the rural revitalization strategy to help the elderly in rural areas bridge the “digital divide”. By deeply analyzing the service potential of e-commerce platforms in areas such as health management, daily care, emotional companionship, and cultural leisure, it assesses the challenges and opportunities they face. It seeks to enhance the quality of life for the elderly in rural areas from multiple aspects including medical services, daytime care, and social needs, with the goal of providing new perspectives and implementation paths for the rural revitalization strategy.
在全球化背景下,随着人口老龄化的加剧和社会结构的变化,社会保障基金面临着越来越大的支付压力。为了确保基金的长期稳定增值并有效分散风险,参与国际金融市场进行多元化投资成为一种重要策略。本文分析了社保基金如何通过参与国际金融市场进行多元化投资,以分散风险并提高收益。具体讨论了境外债券、股票市场、不动产以及金融衍生品等多种投资渠道,并提出了基于宏观经济环境、政治稳定性、法律框架等因素的投资决策考量。同时,强调了建立科学的风险评估模型、设置止损点、动态调整仓位等风险管理措施的重要性。In the context of globalization, with the intensification of population aging and changes in social structure, social security funds are facing increasing payment pressure. In order to ensure the long-term stable appreciation of the fund and effectively diversify risks, it has become an important strategy to participate in the international financial market for diversification. This paper analyzes how the social security fund can diversify its investments by participating in the international financial market to diversify risks and improve returns. Specifically, various investment channels such as offshore bonds, stock markets, real estate, and financial derivatives are discussed, and investment decision-making considerations based on factors such as macroeconomic environment, political stability, and legal framework are proposed. At the same time, the importance of risk management measures such as establishing a scientific risk assessment model, setting stop loss points, and dynamically adjusting positions was emphasized.
随着中国互联网技术的快速进步和移动互联网的广泛普及,电子商务行业已经从传统的电商模式逐步转变为社交电商、直播电商等新兴营销模式。在这一过程中,低线市场逐渐成为各大电商平台争夺的重点区域。本文以拼多多为例,探讨其如何通过直播电商和社交裂变营销策略满足低线市场消费者的需求,并总结其成功经验,为其他电商平台提供参考。文章首先梳理了直播电商与社交裂变的理论基础,包括消费者行为理论和社交网络理论;其次,结合拼多多的实际案例,重点分析了其直播电商策略的互动性和娱乐性,以及社交裂变营销的低成本高效传播模式;最后,总结了这两种营销模式在低线市场中的协同作用。研究表明,拼多多通过精准的市场定位、创新的营销手段、低成本的用户获取机制以及优化的用户体验,成功在低线市场实现了用户规模和平台活跃度的快速增长,为其他电商平台提供了重要的借鉴意义。With the rapid progress of China’s Internet technology and the widespread popularity of mobile Internet, the e-commerce industry has gradually changed from the traditional e-commerce model to the emerging marketing models such as social e-commerce and live e-commerce. In this process, the lower-tier market has gradually become a key area for major e-commerce platforms. This article takes Pinduoduo as an example to explore how it meets the needs of consumers in the lower-tier market through live e-commerce and social fission marketing strategies, and summarizes its successful experience to provide reference for other e-commerce platforms. This paper firstly sorts out the theoretical basis of live e-commerce and social fission, including consumer behavior theory and social network theory. Secondly, combined with the actual case of Pinduoduo, the interactive and entertaining nature of its live e-commerce strategy, as well as the low-cost and efficient communication mode of social fission marketing are analyzed. Finally, the synergy between these two marketing models in the lower-tier market is summarized. The research shows that Pinduoduo has successfully achieved rapid growth in user scale and platform activity in the lower-tier market through accurate market positioning, innovative marketing methods, low-cost user acquisition mechanism, and optimized user experience, which provides important reference for other e-commerce platforms.
随着“低卡”一词越来越成为食品商的营销卖点以及国家对健康生活方式的大力宣传,消费者在购买食品决策中也愈来愈看重食品热量因素。但在多数购买过程中,消费者只凭感官估算食物热量。并且对于快速流通的包装品,消费者更倾向于依赖视觉评估商品。此外,人们对事物色彩的冷暖感知会使其对该事物产生联想,通过意识的信息加工,从而形成对事物的印象。本研究通过定性研究与实验的手段,探讨饮料包装色彩对消费者感知饮料热量的影响。研究发现:暖色调包装和冷色调包装可以使消费者对饮料的热量感知不同;对于相同的饮料,不同的包装颜色,受暖色调影响的消费者对饮料的热量感知高于受冷色调影响的消费者;通过冷色调与暖色调包装感知热量的程度不受性别、年龄与饮用饮料频率的影响;绿色饮料包装是热量感知最低的颜色,红色饮料包装是热量感知最高的颜色。As the term “low-calorie” increasingly becomes a marketing point for food merchants and with the national promotion of a healthy lifestyle, consumers are paying more and more attention to the caloric content of food in their purchasing decisions. However, in most purchasing processes, consumers rely solely on sensory estimation to gauge the caloric content of food. Moreover, for fast-moving packaged products, consumers tend to rely more on visual assessments of the goods. In addition, people’s perception of the warmth or coolness of colors can lead to associations with those colors, forming impressions of objects through the processing of information in consciousness. This study explores the impact of beverage packaging colors on consumers’ perception of beverage calories through qualitative research and experimental methods. The study found that: warm color packaging and cold color packaging can lead to different perceptions of beverage calories among consumers;for the same beverage, consumers influenced by warm tones perceive higher caloric content than those influenced by cool tones;the degree of caloric perception through cold color and warm color packaging is not affected by gender, age, or frequency of beverage consumption;green beverage packaging is the color with the lowest perceived calories, while red beverage packaging is the color with the highest perceived calories.
