How are novel organizations able to build a positive reputation while attempting to enter into a system with established organizations? To address this, we examined the field of elite‐level amateur hockey. Private Secondary Schools (PSS) are novel in that they offer a nontraditional pathway for players with respect to fielding elite‐level hockey teams. Findings from interviews with PSS with elite‐level hockey programs revealed that PSS highlight their Selection Processes, Player Development Practices, and the enhanced Player Experience in an effort to build a positive reputation. This study contributes to the literature on reputation by showing that novel organizations can build a reputation through highlighting the unique value they add. Copyright © 2016 ASAC.

研究目的:立足新时代党和国家机构改革背景,分析自然资源管理改革目标定位和面临挑战,明确未来自然资源管理改革价值导向与战略选择。研究方法:文献研究法,综合分析法。研究结果:自然资源管理改革的目标定位是实现"五统一",即统一调查评价、统一确权登记、统一"多规合一"和用途管制、统一资产管理和统一督查监管。针对当前自然资源管理理论储备不足、开发利用伦理缺乏科学引导、开发和保护矛盾冲突长期存在、新管理体制效能有待实践检验等挑战,自然资源管理改革亟需注重"公平效率"、强调"永续利用"、融合"三资一体"、构建"有效市场",切实重塑自然资源管理新格局。研究结论:新时代自然资源管理改革应该以权籍为基础,完善自然资源市场体系;以规划为龙头,构建国土空间规划体系;以"三线"为底线,推进全域国土空间用途管制;以整治为抓手,推进"山水林田湖草"生命共同体综合治理;以法制为保障,构建自然资源管理法律体系,从而塑造"三体系一管制一治理"的自然资源管理新格局。  相似文献

Upgrading in global value chains (GVCs) is an important path for developing countries to move along to capture higher benefits. Several qualitative studies of GVCs have identified two main upgrading types: economic (product, process, functional, and inter-sectoral) and social upgrading. The upgrading concept is widespread in productive sectors such as processed food, which has become a key export for developing countries. However, they have confronted multiple product standards required by global buyers. This study uses a case study of Thailand’s processed food exports (TPFEs). Although Thailand is a leading exporter of processed food, the country needs to upgrade in many areas related to production to meet global product standards and requirements. If Thailand fails to comply with global product standards, it will lose its export competitiveness. This study uses a gravity model to evaluate the impact of economic and social upgrading (EUP and SUP) on TPFEs. Our results show that upgrading types are significant in TPFEs, particularly for exports to developed countries. Process upgrading has a negative impact on TPFEs because of increased production costs to comply with product standards. However, process upgrading can lead to increased producers’ and exporters’ knowledge about how to comply with international standards. Consequently, process upgrading exhibits a lagged positive effect on TPFEs.  相似文献

Shopping with companions plays a crucial role in daily consumer activities. However, only a few studies have explored the influence of this factor on consumers’ patience. We conducted four studies, including two field studies, to investigate the effects of shopping with companions (e.g., friends and peers) on purchase decisions. We found that consumers exerted greater effort when shopping with friends and peers by spending more money and being willing to wait longer for a product. This effect could be explained by three mediators: positive emotions, negative emotions, and perceived value, in which the hedonic and social value, unlike the utilitarian value, played essential mediating roles. This study elucidates the underlying psychological processes involved in purchase decisions shaped by companions. Retailers should encourage shopping with companions to increase sales and customer retention.  相似文献

With the increasing scarcity of natural resources, the ability to maintain quality standards during resource-scarce times becomes more critical for business performance. Theories on managing resource scarcity cannot be easily tested in contexts where resources are still abundant. This study therefore turns to an emerging market context in which natural resource availability naturally varies strongly between seasons, namely, that of Ethiopian pastoralists who for many generations learned to adapt to natural resource scarcity. Central to our theory is the natural resource deployment capability, which is the ability of a business to make efficient and effective use of available resources to maintain business performance during resource-scarce times. Using three-wave longitudinal data from 120 pastoral family-based livestock businesses, the study shows that when resources are scarce or extremely scarce, market knowledge helps to better deploy the scarce natural resources, leading to higher product quality. The findings imply that businesses with a better understanding of markets have stronger natural resource deployment capability. The lesson for businesses that are confronted with approaching resource scarcity is therefore to strengthen their ability to deploy resources efficiently and effectively by strengthening their market knowledge in which such capability is rooted.  相似文献

This article investigates the differences in the application and impact of digital technologies between manufacturing subsidiaries and lead companies, the principal orchestrators of global automotive value chains. Utilising a dataset of 10 in-depth interviews with automotive industry actors, we analyse headquarters–subsidiary differences in the patterns of digitalisation-driven upgrading. A theoretical framework is offered that explains why the significant upgrading achievements of manufacturing subsidiaries deploying industry 4.0 technologies will not reduce the gap between lead companies and manufacturing subsidiaries in terms of value generation. We show that the concept of ‘industry 4.0’ is much narrower than that of ‘digitalisation’ and transition to smart factories is only part of the digital transformation story. Industry 4.0 technologies contribute to the upgrading of operations, and enable subsidiaries to take on production-related knowledge-intensive assignments (functional upgrading). Conversely, digitalisation serves lead companies’ strategic differentiation efforts, and facilitates achieving competitive advantage: the latter are crucial for value capture.  相似文献

[目的]针对全国31个省(市、区)(不含港澳台地区)、自然资源依赖度高的地区和自然资源依赖度低的地区,从整体和分区域研究自然资源依赖对城乡收入差距的影响,探究不同区域其影响程度的差异性,进而为弱化各区域城乡收入差距,解决由城乡收入差距拉大造成的各类社会矛盾具有重要的现实意义。[方法]从理论上分析了自然资源依赖对城乡收入差距的影响,并利用1999—2017年的省级面板数据,运用固定效应模型,从全国和分区域实证分析了自然资源依赖对城乡收入差距的影响。[结果]针对全国,自然资源依赖会拉大城乡收入差距; 分区域结果,针对自然资源依赖度高的地区,自然资源依赖拉大城乡收入差距; 针对自然资源依赖度低的地区,自然资源依赖对城乡收入差距影响不显著。[结论]为缩小城乡收入差距,需要降低经济体对自然资源的依赖,针对自然资源依赖度高的地区,政府通过将部分自然资源收益转化为农业创新基金和农村基础设施投入,促进自然资源收益向农村公共资本转化,完善现有的自然资源收益分配及转化制度; 鼓励资源型产业技术创新,加大研发投入,延长资源产业链; 加大农村教育投入、提升农村人力资本质量。  相似文献

基于2007-2018年中国A股上市公司数据,本文考察了机构交叉持股对企业价值的影响及其作用机制。研究发现,机构交叉持股显著提高了企业价值,在考虑内生性问题和替换主要变量后结论依然较为稳健。交叉持股机构投资者能够成为更加积极的监督者,主动参与公司治理,缓解代理问题,同时促进同行业企业间产品市场协作,改善企业的产品市场表现,进而提升企业价值。此外,相比其他类型的投资者,长期、独立以及稳定型的交叉持股机构投资者对企业价值的促进作用更显著,进一步印证了监督治理渠道的作用。机构交叉持股推动产品市场协作,主要是通过提高企业创新能力和营业利润率。本文结论证实了机构交叉持股的正向协同效应,对完善中国资本市场制度体系和促进企业可持续发展具有重要意义。  相似文献

This paper explores the performance determinants of Airbnb listings, analyzing three research questions. First, the study investigates the different effects generated by the antecedents on price and revenue; second, it ranks different groups of variables; third, it distinguishes between private rooms and entire homes or apartments. These research questions are addressed by analyzing Airbnb listings in Milan, a business city where the sharing economy is growing fast. In particular, the study will use the monthly data of all Airbnb listings in Milan recorded by AirDNA during the period from November 2014 to June 2019, which consists of 323,184 total observations. Some hedonic price models are calculated, adding the Shapley value approach. Empirical findings show some important differences between price and revenue determinants. Furthermore, listing type and size, along with location and seasonality, are by far the most important factors that explain performance differentials among Airbnb properties.  相似文献
