The organizational design literature strongly supports the notion of “structure follows strategy”, and suggests that a misfit between the two has a negative effect on performance. Building on this line of argument, we examine to what extent the (mis)fit between purchasing strategy and purchasing structure impacts purchasing performance. We focus on cost and innovation purchase category strategies, and examine how the deviation from an ideal purchasing structure defined along three dimensions (centralization, formalization, and cross-functionality) impacts purchasing performance. Analysing data collected from 469 firms in ten countries, we demonstrate that a strategy-structure misfit negatively impacts purchasing performance in both cost and innovation strategies. We also find that purchasing proficiency is a mediator in this relationship between misfit and performance. Our findings aid managerial decision making by empirically validating the necessity of having the right purchasing structure for successfully executing different purchasing strategies.  相似文献

This article develops theory about an agency problem affecting the strategic human capital (SHC) of the firm. It proposes three categories of SHC‐related choices managers must make that imply a trade‐off between near‐ and long‐term performance. Dispersed shareholding, firm coverage by securities analysts, and their practice of publishing quarterly earnings forecasts are argued to entail a bias in management incentives, shifting the balance in this trade‐off toward near‐term performance. To restore the balance, securities analysts would need to distinguish transitory from recurring effects of SHC‐related choices in their valuation models (e.g., treating certain labor cost savings during cyclical downturns as transitory). Restoring the balance would also require them to anticipate long‐term effects in their long‐term earnings forecasts (e.g., long‐term positive effects of retaining employees with valuable skills during cyclical downturns). The article discusses specific transitory cost effects and long‐term effects they could potentially take into account. The skills and incentives needed by analysts to account for such effects are argued to vary across firm segments.  相似文献

Vertical specialization (VS) is quantified by the VS share, which measures the average import content per dollar of exports. A characteristic of China’s export trade is its strong dependence on assembly and processing activities. To take proper account of this, China’s VS shares should explicitly distinguish processing export production from other production. We estimate China’s annual VS shares from 2000 to 2012—the latest year for which a special input–output table is available that makes such an explicit distinction. We find that VS shares increased from 2000 to 2004 and subsequently started to decrease. To explore why it has declined, we introduce a new structural decomposition approach. We find that the decrease of the VS share appears to have been driven mainly by the substitution of imported intermediates by domestic products. This occurred in particular in the production of exports, which implies an upgrading of China’s position in global value chains.  相似文献

Companies commonly issue sustainability or corporate social responsibility (CSR) reports. This study seeks to understand worldviews of corporate sustainability, or the corporate message conveyed regarding what sustainability or CSR is and how to enact it. Content analysis of corporate sustainability reports is used to position each company report within stages of corporate sustainability. Results reveal that there are multiple coexisting worldviews of corporate sustainability, but the most dominant worldview is focused on the business case for sustainability, a position anchored in the weak sustainability paradigm. We contend that the business case and weak sustainability advanced in corporate sustainability reports and by the Global Reporting Initiative are poor representations of sustainability. Ecological embeddedness, or a locally responsive strategy that is sensitive to local ecosystems, may hold the key to improved ecological sensemaking, which in turn could lead to more mature levels of corporate sustainability worldviews that support strong sustainability and are rooted in environmental science. This must be supported by government regulation. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment  相似文献

The growing body of literature on “accessible tourism” lacks a critical scholarly debate around its specific language use and nomenclatures. To fill this gap, this paper provides a first examination of language. Language provides a unique capability to resist, strengthen and reframe identities of individuals and groups, yet can also reinforce, weaken and perpetuate dominant worldviews of disability. A content analysis examined previous accessible tourism literature with results illustrating that diversity exists amongst the varying terminologies adopted by scholars. Terms were employed loosely, inconsistently and interchangeably, euphemistically with erroneous understandings and nuances. The paper concludes with critical discussion about the power of researchers to (re) produce oppression through language that maligns and misrepresents, or to (re) conceptualise and (re) construct the world we live in with liberating language that facilitates positive social change.  相似文献

ABSTRACT

This study aims to explore the typology of hotel crime and how it is related to guests’ fear of crime based on a cause-and-consequence model. A total of 873 TripAdvisor reviews were content-analyzed to develop a typology of hotel crime. High-class hotels experienced more theft, fraud, and burglary while low-class hotels encountered more prostitution and drug-related activities. Hotel guests generated a higher fear of crime when crime occurred inside guest rooms, especially in cases of burglary, theft, or fraud. Reviews mentioning crimes were perceived to be more helpful. Managerial implications and best practices of crime prevention are provided for hotel practitioners.  相似文献

This study conducted a textual analysis of The New York Times to examine the U.S. tourists’ perceived image of China as a destination by comparing the two periods of January 1980–May 1989 and January 2005–December 2015. The study found a drastic shift of the U.S. tourists’ affective image of China as a destination from being favorable and positive in the early period to being unfavorable and negative in the recent period. The affective image was characterized by the two domains of Exoticism and Sense of Superiority in the 1980s, as compared to the two domains of Ordinary and Negative National Image in the recent 10 years. Paradoxically, such a sentimental shift on the part of the U.S. tourists occurred while their perception of China’s destination attributes either did not change or grew more positive.  相似文献

为了研究骨料形态对再生混凝土材料力学性能的影响,基于势能原理的基面力元法,利用图像处理技术和MATLAB软件,建立了再生混凝土真实骨料细观模型。应用FORTRAN分析软件对再生混凝土试件进行单轴拉伸试验的数值模拟,研究了真实骨料细观模型再生混凝土宏观应力-应变曲线变化规律和试件的破坏形态。结果显示,真实骨料模型得到的宏观应力-应变曲线和试验曲线吻合度较高,骨料形状对试件的破坏形态影响较小。模型可真实地模拟再生混凝土在单轴拉伸作用下的损伤破坏过程,准确地反映试件的实际骨料形态。  相似文献

采用网络分析方法,对1995—2014年环渤海地区区域经济空间网络关联结构进行分析,研究发现:环渤海地区区域经济空间网络关联特征显著,分为“辽宁”和“京津冀鲁”两个子网络;网络密度稳步上升,但仍然较低;核心区域的经济比重有所降低,但份额始终较大;网络效率在波动中趋降,空间溢出效应趋于显著。其中,北京、天津、济南等9地属于“主受益”板块,石家庄、保定、潍坊等19地属于“经纪人”板块,沈阳、大连、鞍山等4地属于“双向溢出”板块,而秦皇岛、承德、葫芦岛等12地属于“净溢出”板块。产业结构转型升级、控制FDI区域差异以及投资多元化等有利于环渤海地区增强区域经济空间关联。应多途径构建区域经济关联通道,打造“环型”网状关联经济,并通过产业转型升级和经济多元化发展增进区域经济空间关联。  相似文献
