The purpose of this study is to re-conceptualize the conventional marketing mix for Bottom of the Pyramid (BoP) markets and propose a revised framework by reorganizing the elements based on the customer perspective while retaining the principles of services marketing. Primary data was collected through a questionnaire with a sample size of 400 people from both urban and rural markets in the BoP. Findings indicate that the needs and perspective of the BoP members is distinct from the Middle of the Pyramid (MoP). Managers should consider this point while formulating marketing mix strategies for BoP markets. The present study is the first of its kind to present a revised marketing mix framework for customers in the BoP markets. The framework comprises five Ps, including personalization, product, place, the process of service delivery and price. Thus, a theoretical contribution is made in the context of service marketing and the BoP.  相似文献

The travel, tourism and hospitality industries have been the worst affected of the world's major economic sectors during the COVID19 pandemic, which has had a devastating effect on both destinations and organisations. Drawing from a sample (N = 385) of adult permanent residents of Athens, Greece, the study examines the impact of COVID19 upon holiday intention. The chaordic systems are evaluated through the use of fuzzy-set Qualitative Comparative Analysis, whilst the study also used Necessary Condition Analysis for the calculation of the size effects of the examined conditions. The findings reveal two sufficient complex configurations leading to holiday intention: (i) holiday risks, and (ii) impact of COVID19. Based on the results, the article also offers a set of managerial implications. The contribution of the study is to both theoretical and methodological tourism domains.  相似文献

区域协调发展不仅受到资本积累数量的影响,更受到资本匹配质量的制约。在拓展MRW模型的基础上,理论分析“实物资本-人力资本-社会资本”最优匹配存在性与高效经济增长的关系,进一步构建资本匹配程度与匹配质量通过创新力培育实现落后地区经济赶超,进而影响区域协调发展能力的传导路径,并利用中国省级面板数据进行实证检验。结果表明,实物资本、人力资本与社会资本存量之间存在最优比例关系,且资本匹配质量主要通过创新力培育影响区域协调发展水平;资本匹配整体上有利于区域协调发展,东部地区资本匹配度对区域协调发展的促进作用高于中部地区、西部地区;机制检验发现,资本匹配通过组织创新效应实现区域协调发展的解释程度最大,其次为技术创新效应,最后是产业创新效应。  相似文献

This study examines the global nature of the recent crisis under bivariate Markov-switching models for pre- and post-crisis periods using the breakpoint of August 9, 2007. It quantifies international synchronization of boom-bust regime switches to investigate contagion-type dynamic comovements of Real Estate Investment Trusts (REITs). Global REIT markets display persistent bust regimes from September 2008 to May 2009, whereas the regime-switching patterns are not significant in the pre-crisis period. The results provide new evidence for global REIT contagion phenomena and suggest greater difficulties in diversifying risks across global REIT markets during the post-crisis period.  相似文献

Faultlines can affect a board of director’s effectiveness in supervising senior managers, which in turn affects the value of a company’s cash holdings. Based on sample data from Chinese A-share listed companies from 2004 to 2016, we examine the relationship between board faultlines and the value of cash holdings. The empirical results indicate that board faultlines have a significant inhibitory effect on cash holding value. This inhibitory effect is stronger for board faultlines resulting from deep-level attributes. Furthermore, the inhibitory effect of board faultlines is stronger in state-owned enterprises (SOEs) than in non-SOEs. As an important governance mechanism, management shareholdings can reduce agency costs and mitigate the negative impact of board fissures on cash holdings. Overall, we enrich the literature on the economic consequences of board faultlines and their influence on cash holding value. We also offer companies practical suggestions for improving the supervisory mechanism of their board of directors.  相似文献

当市场环境不好以及不确定性增加时,基金进行安全投资转移。企业积极履行社会责任所形成的声誉资本具有“类保险”作用,在面临负面事件或不确定性环境冲击时能够防止股价大幅下跌和市值损失;基金是否会在市场环境不好时将投资组合转向社会责任绩效更高的股票进行安全投资转移呢?使用2010—2017年开放式基金样本,实证检验了企业社会责任、市场环境与安全投资转移之间的关系。研究发现,在市场环境表现不佳时,基金避险需求增加,倾向将投资组合更多地转向社会责任绩效高的股票进行安全投资转移;进一步研究发现基金和基金经理特征影响基金的安全投资转移行为,净资金流入较少、历史业绩差、经理选股能力差的基金根据企业社会责任进行安全投资转移的程度大。研究还发现,基金的安全投资转移行为对基金业绩和基金收益波动产生了积极影响。  相似文献

The “industry nurturing agriculture” reforms and World Trade Organization accession led to dramatic growth in public expenditure and international trade in China’s agricultural sector. This article aims to estimate the effects of public expenditure and trade on agricultural productivity in China for 2004–2015. A semi-parametric production function with shape constraints is introduced to derive more accurate productivity before the productivity determinants are analyzed with an emphasis on public expenditure and trade. The empirical result shows that public expenditure and exports can effectively improve agricultural productivity, while imports have no significant effects. Policy implications are discussed in the context of supply-side reforms.  相似文献

Despite longstanding research on the landslide hazard assessment and mapping, the use this information in regional planning applications remains largely unclear. There is still a need for novel methods to interpret the results of hazard analyses. In this respect, the main research question of this study is how the landslide hazard maps can be evaluated in planning practice. To evaluate this issue, a comprehensive case study was carried out and a new methodology, defining the order of priority for the locations where mitigation measures are applied was developed. The investigations were carried out in the Melen Dam reservoir, which provides potable water to the city of Istanbul, and the dam protection area (Duzce, Turkey) in four main stages: (i) Evaluation of the general characteristics of the study area, (ii) preparation of landslide inventory, (iii) development of landslide hazard model, and (iv) implementation of the results of hazard analyses in planning. As a consequence, a decision support system that can evaluate analytically complicated outputs “PCombined”, “PAL min.”, and “LTotal” and provide clear decisions “Urgent”, “Primary”, and “Secondary” was suggested. Considering the limited resources available for the mitigation measures, the determination of mitigation priorities for the micro-catchments constitutes the key land-use policy for the protection of the dam reservoir.  相似文献

Since the beginning of the 21st century, China has undergone a promotion of industrialisation, urbanisation and agricultural modernisation. This promotion has triggered the mass migration of rural labour forces into cities, leading to the virtual situation of the separation of farmland contract and operation rights. To respond to this issue, the central government proposed a strategy of farmland reform in China. Such reform aims to transform the former ‘Bipartite Entitlement System’ into a ‘Tripartite Entitlement System (TES)’.1 Land registration provides the means for recognising formalised property rights and regulating the characteristics and transfer of land-related rights. As for farmland registration in China, it serves as a basis to explore effective forms of collective farmland ownership by implementing collective farmland ownership, stabilising farmers’ contract rights and liberalising farmland operation rights. Thus, in this study, on the basis of the farmland tripartite entitlement (hereinafter referred to as ‘FTE’) reform in China, we develop a Land Administration Domain Model (LADM)-based TES model that will serve as the basis of subsequent system development. Specifically, first, we summarise the evolution process of China’s farmland rights system since the foundation of new China. Second, we propose a farmland rights system after the FTE reform. Then, the corresponding TES model is developed based on the LADM standard and some instance-level diagrams for farmland administration activities. The new functionality of the model includes improved structuring of farmland rights and restrictions (and related source documents) and improved expansion of the land information infrastructure to rural areas.  相似文献
