Prior research has shown a correlation between market orientation and business performance as measured through new product success. Market orientation has traditionally been measured through the MKTOR and MARKOR scales developed by Narver and Slater and Kohli et al., respectively. We examine whether there might be a different, complementary way to study market orientation. Kohli and Jaworski discuss the role of networks in achieving higher levels of market orientation, but network analysis has not previously been used to study market orientation. Following Kohli and Jaworski we find that network analysis can show how information is gathered and disseminated within a group; and following Narver and Slater we find that network analysis can be used to examine customer orientation and coordination. We discover a possible association between the organization’s structure and its level of coordination, and that certain roles within the group facilitate increased customer orientation within the team. Our research suggests that network analysis, particularly when managers participate in the interpretation of results, can be an effective means of identifying and correcting obstacles to a team’s market orientation. We believe our research contributes to theory by showing an alternative, complementary way to study market orientation and suggests factors that contribute to a group’s level of market orientation. We believe that this research contributes to practice by providing managers with a practical measure to improve their organization’s market orientation, thus increasing the likelihood of new product success.  相似文献

Recognizing the critical role that information technology (IT) can play for the aging population, local governments tend to take responsibilities for IT-enabled senior care service delivery. Formulating IT governance mechanisms is important for governments to perform their responsibilities and maximize public value. As service arrangers, governments’ actions are affected by complex external environments for legitimacy, which has been largely ignored in the existing studies. By incorporating the strategic and institutional perspectives of legitimacy into Savas’s service delivery structure, this study developed a triadic framework that accounts for different contextual determinants related to the external market environment and the institutional environment to investigate the formulation of IT governance mechanisms. A survey involving 329 town-level governments in Beijing, China, was done to validate our research model. The results illustrate that the demand-supply market forces have direct impacts on IT governance mechanism formulation in local governments. Institutional pressures exert a mediating effect by transiting the supply market force into governments’ actions. Our triadic framework reveals a dynamic service delivery structure, contributing to Savas’s service delivery structure and IT governance research.  相似文献

Many companies invest considerable resources in developing Business Analytics (BA) capabilities to improve their performance. BA can affect performance in many different ways. This paper analyses how BA capabilities affect firms’ agility through information quality and innovative capability. Furthermore, it studies the moderating role of environmental turbulence, both technological and in the market. The proposed model was tested using statistical data from 154 firms with two respondents (CEO and CIO) from each firm. The data were analysed using Partial Least Squares (PLS)/Structured Equation Modelling (SEM). Our results indicate that BA capabilities strongly impact a firm’s agility through an increase in information quality and innovative capability. We also discuss that both market and technological turbulence moderate the influence of firms' agility on firms' performance.  相似文献

摘要:本文以我国上市公司的数据为样本,利用企业的投资能力和市场份额描述产品市场竞争力,从行业竞争差异的角度探讨了资本结构对我国企业产品市场竞争力的影响。研究表明资本结构对企业的产品市场竞争力具有显著影响,且这种影响对处于不同竞争程度行业的企业有所差异。资本结构的提高对企业的投资能力会产生负效应,且这种负效应随着行业竞争程度的下降也会有所减弱。总体上,资本结构的提高有利于市场份额的提高,且这种正效应也会随着行业竞争程度的下降而下降。但当企业本身资本结构已经处于一个较高的水平时,资本结构的提高易使企业的市场份额下降,从而可能陷入财务危机,尤其当行业竞争激烈时。本文的研究不仅丰富了我国资本结构对产品市场竞争力影响的研究文献,也为企业决策者在制定目标资本结构时提供了参考。  相似文献

Blockchain technologies have grown in prominence in recent years, with many experts citing the potential applications of the technology in regard to different aspects of any industry, market, agency, or governmental organizations. In the brief history of blockchain, an incredible number of achievements have been made regarding how blockchain can be utilized and the impacts it might have on several industries. The sheer number and complexity of these aspects can make it difficult to address blockchain potentials and complexities, especially when trying to address its purpose and fitness for a specific task. In this survey, we provide a comprehensive review of applying blockchain as a service for applications within today’s information systems. The survey gives the reader a deeper perspective on how blockchain helps to secure and manage today information systems. The survey contains a comprehensive reporting on different instances of blockchain studies and applications proposed by the research community and their respective impacts on blockchain and its use across other applications or scenarios. Some of the most important findings this survey highlights include the fact that blockchain’s structure and modern cloud- and edge-computing paradigms are crucial in enabling a widespread adaption and development of blockchain technologies for new players in today unprecedented vibrant global market. Ensuring that blockchain is widely available through public and open-source code libraries and tools will help to ensure that the full potential of the technology is reached and that further developments can be made concerning the long-term goals of blockchain enthusiasts.  相似文献

从行为金融学视角出发,采用“产业政策--投资者关注--企业创新策略选择”这一研究思路,以2011-2015年我国A股制造业上市公司为样本,采用Multinomial Logit-中介效应模型分析产业政策对企业创新策略选择的作用机制。研究发现,与发明专利相比,产业政策的“资源效应”显著增加了企业非发明专利申请的数量。我国证券市场具有典型的投资者有限理性特征,产业政策会带来“投资者关注效应”,当市场有效性不足时会进一步诱使管理层选择低质量的创新策略。对于非国有企业以及不具有政治关联的企业而言,产业政策引致的“投资者关注效应”是诱使其选择低质量创新策略的主要原因。研究结论为更好地引导产业政策和证券市场共同提升企业实质性创新能力提供了经验证据。  相似文献

Information asymmetry in different service products is lacking research. Tourism e-commerce as a dynamic financial market driven by advanced information technology deepens the concern for asymmetry brought to hotel consumers. COVID-19 provides a natural intervention on market asymmetry in the hotel price information, which effects are worth evaluating. This study therefore evaluates the degree of information asymmetry in terms of the lodging price of international tourist hotels (ITHs). Through applying the concept of stochastic frontier approach (SFA), this study estimates the degree of information asymmetry and the inefficiencies. The estimation results indicate that the hotel location, traveler type, operation type may cause different information asymmetry. By comparing with the asymmetry before the pandemic, it is found that the asymmetry in lodging price information decreased since the outbreak of the COVID-19 pandemic. Among the six regions studied, the mean range of information equity degree increased from the original 0.634-0.832 to 0.7633-0.866. It indicates that the outbreak of COVID-19 changed the structure of the consumer groups in hotel operations and then affect the hotelier's pricing strategy.  相似文献

There is a body of research that highlights the role of data management to improve the quality of data, which in return improves organizational performance. The literature in data management has indicated the five theoretical constructs used to understand the factors influencing data quality, including top management support, capability on the regulation and process management, business-IT alignment, staff participation, and integration of information systems. However, it is unclear how these theoretical constructs can be utilized to understand the antecedents of data completeness as a dimension of data quality. Following that stream of research, the current paper examines the factors influencing data completeness in electronic medical records (EMR). The scope of this study is by only surveying medical professionals at healthcare settings in northern Nevada. The empirical results reveal that resources should be added as one of the antecedents of data completeness in EMR.  相似文献
