Online collaborative consumption enhances peer networks, members of which communicate, collaborate, and even deliver services to one another via digital sharing platforms. Despite the tremendous increase in collaborative consumption, due in large part to the development of the Internet, the reality of the economic and social movements that underpin this trend is much less visible. Of course, not all consumers seek collaborative consumption or interact through online platforms. Using a qualitative approach, this paper aims to investigate motivational factors and barriers against collaborative consumption and to establish a typology of collaborative consumer profiles, identifying the most suitable type of online sharing platforms for each profile. The findings reveal the following collaborative consumer profiles: committed, pragmatists, intermittent, and skeptical, each demonstrating different preferences for the different type of online sharing platform.  相似文献

Many planning authorities and airports study measures to increase public transport use for airport ground access and egress. At the same time, an increase in real estate development at and around airports is occurring, both due to airports seeking new revenue possibilities and other developers attempting to profit from high value locations. This paper considers non-aeronautical activities at large airports, largely commercial centres and transit hubs, as land uses that have the potential to improve the situation for operating public transport services. In order to assess potential benefits and disadvantages, four research questions are considered: (1) Can the additional travel volume reach levels at which it has a significant impact? (2) To what extent do non-aeronautical activities influence the public transport access system? (3) Is the resulting demand distribution better or worse regarding peaking behaviour? (4) Is there a potential for the resulting overall demand to bring about capacity shortages?A case study is conducted at the airport of Zurich, Switzerland, which finds that non-aeronautical activities in the direct airport vicinity have led to a situation where the operation of public transport services is much more viable due to overall higher passenger numbers and a more even distribution throughout the day. It is concluded that locating non-aeronautical activities at airports can, in addition to providing commercial benefits to developers, lead to a situation where improved public transport services become feasible.  相似文献

Environmental and social challenges require new sustainable business models, like sharing platforms. However, sharing platforms differ widely in their contribution to a more sustainable society. Whereas idealistic sharing platforms have dominant social goals, other sharing platforms are, or became, commercial. We explore the attractiveness of the typical organizational characteristics of idealistic sharing platforms in the fashion industry context, an industry with negative environmental and social impacts. Based on a literature review and exploratory focus groups, we conduct an online survey using conjoint analysis, completed by 1,512 respondents. Our results reveal that potential users prefer clothes sharing platforms to be small, to not partner with large clothing retailers, to have the possibility to participate in decision‐making, but to not require shareholding.  相似文献

The determinants of migration have been widely studied but research has rarely addressed the roles of food insecurity and gender in the migration decision process. To address these gaps, we examine these relationships for 135,078 individuals across 94 low- and middle-income countries. We use a series of binary-choice models with sample selection and data from the 2014–2015 waves of the Gallup World Poll Survey, which includes the first global measure of individual-level food insecurity. Results, which are robust, indicate that food insecurity is an important determinant of both migration intentions and preparations, and the probability of migration intentions increase monotonically with the severity of food insecurity, and the probability of migration preparations decrease. These relationships also differ significantly by gender and level of gross national income. Evidence suggests a need for increased coordination between the international food security and migration policy agendas.  相似文献

Microfinance targets women and uses loan provision as a tool for empowerment, which translates into better household nutrition, improved education, and a scale down of domestic violence. However, ethnic discrimination in microfinance may exist in countries with a segregated indigenous population. We assessed this possibility with a field experiment in Bolivia. The controlled laboratory experiment evaluated whether credit officers rejected microloan applications based on the interaction effect of ethnicity and gender of potential borrowers. Point estimates of a Bayesian mixed‐effects logistic regression, estimated with the experimental data, indicate that nonindigenous women have double the chance of loan approval, but indigenous women have only 1.5 times the chance of loan approval when compared with men. While the findings about gender are limited, the evidence for the interaction of gender and ethnicity is more robust and suggests the existence of positive taste‐based discrimination favorable for nonethnic women in Bolivia. We conclude that the affirmative actions towards women promoted by development agencies and microfinance institutions must not overlook ethnicity as an important factor for financial policies of sustainable development. In practice, these policies should be aimed at identifying and reducing both social desirability bias and the structural barriers to financial inclusion that indigenous women may face when trying to obtain access to a loan.  相似文献

平台经济的快速发展使得平台型社会责任消费问题日益被关注。立足平台经济情境下社会责任消费行为的“利他”属性,基于弱关系理论和消费者—企业认同理论,从社会互动视角对计划行为理论进行重塑,在问卷调查基础上通过统计分析方法研究社会责任消费行为意向驱动因素。实证显示:行为态度、社会规范、感知行为控制及平台企业社会责任认同对社会责任消费行为意向的生态消费、善因消费和诚信消费三个维度均有不同程度的正向影响,其中社会规范是最大的影响变量;行为态度在社会规范、感知行为控制、平台企业社会责任认同与社会责任消费行为意向之间起中介作用。修正后的计划行为理论实现了个人与社会、理性逻辑和情感逻辑的有机统一,能对平台经济视阈下社会责任消费行为意向进行有效的解释与预测,从而为平台社会责任生态化治理提供一定启示。  相似文献
