The rapid development of e-commerce is driving many traditional manufacturing enterprises to establish online channels. This typically leads to online and offline channel conflicts for these enterprises. Existing studies on channel conflict management primarily focus on describing the conflicts and discussing the types of strategies. Utilizing the case study method and taking the resource orchestration perspective as the theoretical lens, this study examines the implementation processes of online and offline channel integration and segmentation strategies in two Chinese manufacturing enterprises. The findings reveal the prerequisite to select online and offline integration and segmentation strategies, and specific resource orchestration actions and capabilities generated under the guidance of the integration and segmentation strategies. This study has theoretical implications to the online and offline channel conflict management strategies by extending the “what” question to the “how” question. In addition, this study also provides references to practitioners for selecting and implementing appropriate online and offline channel conflict management strategies.  相似文献

With the prevalence of digital technologies, various services have grown digitalized. Specific to the marketing section, multichannel has been gradually replaced by omnichannel, which aims to integrate all the physical and digital channels tightly. Although omnichannel has received considerable attention, there is still a dearth of research that theorizes the multi-faceted impacts of digitalization on omnichannel. This study thus extends social cognitive theory (SCT) to the digitalized context and contextualizes the digitalized customer and digitalized environment as mobile identity and channel integration quality, respectively. Moreover, based on the self-regulation process of human agency, we incorporate omnichannel self-efficacy, satisfaction, and habit as the agentic factors to interpret a customer’s conscious (ability and expectancy beliefs) and unconscious (automatic behavioral tendency) decision-making under the omnichannel setting. Through an online survey of 401 omnichannel customers, we find support for all the proposed hypotheses. Implications and limitations of this study are further discussed.  相似文献

运用文献资料、逻辑分析等方法,对我国电视体育频道的设置格局与运营状况进行了研究。研究结果:我国体育频道通常依据各电视台所在的行政区域垂直分布,行政归属分属于各电视台,目前我国境内尚没有广电系统以外的民间或社会力量拥有的体育频道。与我国区域经济发展的格局相呼应,体育频道在全国分布并不平衡,有影响力的强势体育频道多分布在经济发达、人口众多、电视媒体实力雄厚的省、市和地区。大部分体育频道播出内容以体育节目为主,但也包括其他非体育节目类型,直播赛事的比例也普遍低于国外著名体育频道,说明我国体育频道播出专业化水平还有待提高。中央台五套在电视体育节目收视市场显示了强大的竞争实力,我国体育频道发展还处于央视"一枝独秀"的格局,体育频道"百花齐放"的竞争格局还远未形成。  相似文献

An experimental 2 (channel) × 2 (gender) × 3 (time) mixed factorial design (N = 159) was applied to test and compare how individual dimensions of intercultural sensitivity might be affected by two channels: a virtual environment (i.e., Second Life®) versus a Web environment. Using a modified version of Chen and Starosta's Intercultural Sensitivity Scale (ISS), the study sought to identify which of the five ISS dimensions played the most influential role in intercultural sensitivity outcomes: interaction enjoyment, interaction engagement, interaction confidence, interaction attentiveness, or respect for cultural differences. Results showed that one's willingness and effort toward understanding an intercultural interaction – interaction attentiveness – played the greatest and most statistically significant role in intercultural sensitivity outcomes, and that this effect was greatest within the virtual environment channel. Gender effects were also found, in which men experienced greater enjoyment but women expressed more attentiveness.  相似文献

This paper describes a Least Squares (LS) channel estimation scheme for MIMO OFDM systems based on time-domain training sequence. We first compute the minimum mean square error (MSE) of the LS channel estimation, and then derive the optimal criteria of the training sequence with respect to the minimum MSE. It is shown that optimal time-domain training sequence should satisfy two criteria. First, the autocorrelation of the sequence transmitted from the same antenna is an impulse function in a region longer than the channel maximum delay. Second, the cross-correlation between sequences transmitted from different antennas is zero in this region. Simulation results show that the estimator using optimal time-domain training sequences has better performance than that using optimal frequency training sequence at low signal-to-noise ratio (SNR). To reduce the training overhead, a suboptimal training sequence is also proposed. Comparing with optimal training sequence, it has low computation complexity and high transmission efficiency at the expense of little performance degradation.  相似文献

The exceptional performance of Dell Computer in recent years illustrates an innovative response to a fundamental competitive factor in the personal computer industry - the value of time. This article shows how Dell's strategies of direct sales and build-to-order production have proven successful in minimizing inventory and bringing new products to market quickly, enabling it to increase market share and achieve high returns on investment. The Dell case illustrates how one business model may have inherent advantages under particular market conditions, but it also shows the importance of execution in exploiting those advantages. In particular, Dell's use of information technology (IT) has been vital to executing both elements of its business model - direct sales and build-to-order - and provides valuable insights into how IT can be applied to achieve speed and flexibility in an industry in which time is critical. Many of the insights gained from this case can be applied more generally to other time-dependent industries, suggesting that the findings from the Dell case will have implications for a growing number of companies and industries in the future.  相似文献
