Improving access to more modern forms of energy requires supply chains that reach further into rural areas. This paper studies a supply-side intervention intended to foster last-mile distribution of energy-access technologies through local small-scale entrepreneurship. We use a staggered-implementation evaluation design to assess the impact on employment and income outcomes of the intervention, which is a large-scale program in Kenya that supports the diffusion of improved cookstoves and small solar products. The results demonstrate how trained entrepreneurs intensify and diversify their income-generating activities, often by shifting away from subsistence farming as a main source of income. For cookstove entrepreneurs, this goes along with improvements in individual and household incomes as well as perceived economic well-being. Our estimates suggest that impacts do not only differ between the two technologies but also across subgroups including gender, age, and baseline occupation. Our findings substantiate that market-based interventions can foster energy access in rural areas by supporting the establishment of local businesses. We highlight several contextual factors that are of relevance when considering the adoption of this approach.  相似文献

This study focuses on customers' information-sharing behavior in the context of online brand advocacy behavior regarding hotel brands. We aim to explain hotel customers' online brand advocacy behavior through three-sided justice evaluations (i.e., justice for employees, justice for the self, and global belief in a just world), and their hotel satisfaction. Hypotheses are tested by using survey data acquired from 688 individuals on Amazon's Mechanical Turk (MTurk) through partial least squares structural equation modeling (PLS-SEM). The findings show that customers' perceptions of justice for the self positively affect their hotel satisfaction, perceptions of justice for employees and the global belief in a just world positively affect online brand advocacy behavior, and hotel satisfaction also positively affects online brand advocacy behavior. We expand current research efforts on online brand advocacy research and provide theoretical and managerial implications for the development of marketing and management research and practice.  相似文献

Developing and transitional countries often impose a wide variety of entry barriers on foreign direct investments (FDIs). One important reason behind these entry barriers is ideological taboos. However, do these taboos actually affect the inflow of FDIs? With the help of China’s “cultural system reform,” this study uses a panel data of 283 prefecture-level cities in China for 1994–2017 and the difference-in-differences method to evaluate the effect of the cultural system reform on regional FDI. We found that the cultural system reform remarkably promoted the inflow of FDIs by deregulating institutions and removing entry barriers, and the attraction of FDI has slowly increased along with the deepening of the reform. Our conclusions still hold after performing several robustness tests, thereby highlighting ideologies as important barriers to the inflow of FDIs into less developed countries.  相似文献

The role of social media in promoting sustainable attitudes is currently understudied. Underpinned by social learning theory, this study unveils the effect of social media usage and browsing on sustainable purchasing attitude, the underlying mechanism, and the boundary condition. Drawing on a sample of 693 experienced respondents analyzed using structural equation modeling, this study reveals that social media usage and browsing have a significant positive association. Both constructs significantly impact sustainable purchasing attitudes with complementary partial mediation of the drive for environmental responsibility. Further, trust in social media and perceived environmental effectiveness significantly moderate the relationships belongs to the browsing and drive for environmental responsibility. Contrary to the theorization, moderating constructs cannot substantially impact the proposed associations of social media usage. In this manner, the present research is innovative and provides valued knowledge to comprehend social media's role in encouraging sustainable attitudes.  相似文献

交通治理现代化是交通强国建设的重要支撑。交通运输行业超限超载与黑车现象屡禁不止的现实困境,一方面源于早期制度设计阶段遗留的逻辑障碍,一方面源于目前缺乏行之有效的规则来对此类问题进行限制和制约。尽管各级政府对黑车治理高度重视并采取了多种措施,但依然存在黑车辨识难、管理成本高、效率低等问题,尚未达到我国现有施政路线的要求。鉴于此,可抓住管理型政府向服务型政府转型的契机,遵循合法、合理、高效、经济的原则,通过比较分析美国赏金猎人制度来形成制度改革的借鉴。赏金猎人模式作为国外长期摸索得到的经验,有很多值得参考之处。现阶段,赏金猎人模式在我国已经具备试行的基础条件,不仅能够开拓视野,为当前我国面临的交通运输行业治理问题提供制度层面的启示,而且更为重要的是,能够为解决我国超限超载与黑车治理问题提供新的思路。当然,为避免简单借鉴或全盘照搬而导致的水土不服等落地性难题,需要围绕黑车治理困境和超限超载运输这两个具象背景,对不同国别法律解释上的差异加以创新并实现本地化,使之在立法层面稳固的前提下展示其优越性。  相似文献

This study aims to broaden the current knowledge on the antecedents and consequences of customers’ psychological ownership (CPO) from new perspectives in the hotel context. Specifically, this study investigates how self-image congruity and functional congruity affect CPO through impression in memory based on self-congruity theory and also examines two types of customer engagement—customers’ social influence engagement and knowledge-sharing engagement—as new CPO outcomes. Using survey data collected from 433 Chinese hotel customers, this study finds that self-image congruity positively predicts CPO partially through impression in memory, whereas functional congruity positively influences CPO fully through impression in memory. Moreover, the findings indicate that CPO significantly drives customers’ social influence engagement and knowledge-sharing engagement. This study contributes theoretically to the CPO literature by further developing its linkages with congruity perceptions and customer engagement. Practical implications of the findings can help hotel managers effectively promote CPO and customer engagement.  相似文献

20世纪50—60年代既是新中国财政学初建时期,也见证了苏联财政学传统移入和退出的过程。就其理论和实践来源看,苏联财政学是苏联化的马克思主义、苏联特殊年代政治实践和计划经济体制等诸多因素的混合物。虽然它在发展和创新马克思主义财政理论方面作出了首创性的贡献,但其历史局限性也不可避免。在苏联财政学移植中国之时,其中一些负面特征也参与了新中国财政学的重建,并对其后中国财政学的发展起到了长久的羁绊作用。20世纪50年代后期以来,中国财政学“去苏联化”的目标未能完全实现,这一方面源于塑造苏联财政学的思维模式仍然在当时的中国财政学界起着支配作用;另一方面在那些影响财政学发展的主要因素上,当时的中苏两国极为雷同。吸取20世纪50年代中国移植苏联财政学的历史经验和教训,对当下中国合理借鉴域外学术资源、发展和创新马克思主义财政理论,有着重要的借鉴意义。  相似文献

在优化营商环境已成为当前发展中国家引资竞争新优势的背景下,针对优化营商环境影响外资企业FDI动机的考察变得尤为重要。本文在构建企业层面营商环境指数的基础上,考察了发展中国家优化营商环境影响外资企业FDI动机的机制及效应。结论表明:优化营商环境减弱(增强)了外资企业的市场(效率)寻求型FDI动机;内资企业竞争力的增强、外资企业特惠资源的取消和加工贸易型外资企业的存在,使得优化营商环境降低了外资企业的生产率,进而市场(效率)寻求型FDI动机减弱(增强)。细分样本的考察发现,上述结论仅存在于独资企业、工业和低收入国家的外资企业中,对于合资企业、服务业和高收入国家的外资企业,优化营商环境对其FDI动机无显著影响,且生产率的中介效应不存在。本研究从优化营商环境的视角为当前中国引资政策的制定提供了更为具体的政策启示。  相似文献

Extended producer responsibility (EPR) is a proposed policy approach to promoting the circular economy (CE) within the European Union. This research used a policy Delphi to explore perspectives on improving EPR policies to further contribute to the CE goals of the Netherlands. Both the potential improvement and critical reflections discussed by CE and EPR experts and practitioners from this study contribute to a more detailed understanding of the future governance of CE practices. We present various activities to improve EPR and insights from Delphi participants that emerged from the study. This paper shows that whilst actors agree, in essence, that there is a need for modifying EPR, what the specific changes to the form are and to whom the new responsibilities apply is contested.  相似文献
