This work draws on consumer and psychology research to explain sociocognitive aspects of product-market dynamics at a higher
level of specificity than prior research. The authors extend the field’s understanding of market-shaping shared knowledge
through a theory-informed discussion of how shared product knowledge comes to exist and how it changes as product markets
develop. They define shared knowledge as the aspects of product representations that are common across the minds of market
actors, making it possible for them to understand one another. The authors also discuss ways to track shared knowledge content
that is expressed in market narratives. As the characteristics of shared knowledge are explained and linked to stages of product-market
development, the authors develop a set of researchable propositions to guide future research. The theoretical arguments and
propositions in this article complement extant marketing strategy research by integrating individual-level consumer theory
with market evolution models.

中国与东盟建立了“10+1”自由贸易区,近期内由于产业结构相似度高,会对自由贸易区内各国的经济造成一定的影响,尤其是会加大中国对东盟的贸易逆差。但从长期来看,双方相似的产业结构形成了共享的劳动力市场,贸易区内劳动力的国际流动,会促进贸易区内各国经济的发展。 相似文献

A new approach to allocate environmental responsibility, the ‘value added-based responsibility’ allocation, is presented in this article. This metric allocates total environmental pressures occurring along an international supply chain to the participating sectors and countries according to the share of value added they generate within that specific supply chain. We show that – due to their position in global value chains – certain sectors (e.g. services) and countries (e.g. Germany) receive significantly greater responsibility compared to other allocation approaches. This adds a new perspective to the discussions concerning a fair distribution of mitigation costs among nations, companies and consumers. 相似文献

Electric vehicles (EVs) are energy efficient and often presented as a zero-emission transport mode to achieve long-term decarbonization visions in the transport sector. The implementation of a sustainable transportation environment through EV utilization, however, requires the addressing of certain cost and environmental concerns such as limited driving range and battery-charging issues before its full potential can be realized. Nevertheless, a specific type of use of EVs, namely in taxi services, may elicit positive public opinion, as it promises a commitment toward sustainability in urban life. In light of this, this study proposes an integrated approach that combines EV operation with a conceptual design for shared-ride taxi services. As some productivity loss may be naturally expected due to the time spent in charging, it is important to look at whether such performance loss from the passenger and system standpoints can be offset with ingenuity in operational design. In this study, an EV taxi charge-replenishing scheme that can be coupled with a real-time taxi-dispatch algorithm is designed. The proposed EV charging schemes for taxi services are studied via simulations and the effects of the limited driving range and battery-charging details are examined from a system performance viewpoint. The simulation study also reveals illustrative results on the impact of the EV taxi fleet's operation on the charging system. Next, a real-time shared-taxi operation scheme that allows ride sharing with other passengers is proposed to maximize the operational efficiency. The simulation results suggest that the shared-taxi concept can be a viable option to improve on the limitations caused by EV operation. In addition, the importance of projected charging demands and queue delays at different charging locations are also addressed. Some limitations and a future research agenda are also discussed. 相似文献

Estuaries provide advantageous sites for both harbors and fish habitats. In many countries, harbor expansion in estuaries contributed to the decline of fish populations with impacts at the global scale. Restoring these habitats is important to prevent a global biodiversity crisis but is costly and potentially unaffordable for polluters under the Polluter Pays Principle. Such affordability issues prompt decision-makers to reduce environmental targets of restoration programs. Harbor infrastructures destroy fish habitats but generate benefits for society and contribute to the public interest, raising some questions on who is responsible for environmental degradations and who can afford environmental restoration costs? One way to allocate restoration costs is to analyze the amount of harbor services consumed by economic sectors. This paper addresses these questions by computing burden sharing scenarios with an input–output matrix. These scenarios are simulated under the shared responsibility principle to distribute restoration costs among stakeholders in the Seine estuary, France. 相似文献

构建上海合作组织命运共同体是中国政府提出的关于促进上海合作组织长远发展的重大倡议。由于上海合作组织命运共同体理念的提出时日尚短,学术界关于该理念的研究尚未全面启动。要使上海合作组织命运共同体理念成为一个有效的研究议题,不仅需要明晰上海合作组织命运共同体的具体内涵,而且需要将其纳入国际共同体、国际组织和大国外交等议题的研究,提炼出一些具有普遍性的理论命题。就攸关上海合作组织命运共同体构建的重大问题而言,至少需要回答上海合作组织命运共同体提出的理论与实践意义、上海合作组织命运共同体构建应遵循的基本路径、上海合作组织命运共同体构建的基础和条件、上海合作组织命运共同体构建面临的挑战与障碍、学术界能为上海合作组织命运共同体构建提供的对策建议等重大问题。在此过程中,学术界还需将其与周边命运共同体、人类命运共同体等家族相似性的概念纳入同一研究视域,以澄清上海合作组织命运共同体的内涵与外延,辨识上海合作组织命运共同体演变的动力与机制,并从理论层面提炼上海合作组织发展经验的特殊性与普遍性。 相似文献

The proliferation of social media offers new avenues for understanding traveler information sharing behavior. The purpose of this study was to explore the patterns of traveler food sharing experiences on soial network sites, their triggers, and consequences as well as the inter-relationships among these factors. Thirty-three semi-structured interviews and subsequent thematic analysis revealed five major sharing motivation domains including Social and relational, Self-image projection, Emotion articulation, Self-archiving, and Information sharing, all of which were situated along the two continuums (self–others and psychology–functionality) of a two-dimensional plane. This research uncovers fresh insights that are unique to travelers’ food experience sharing and offers theoretical contributions as well as practical implications for destination marketers. 相似文献
