Bandwagon and leapfrog effects in Internet implementation

This paper underscores the critical relationship between innovation adoption and innovation implementation, particularly how two contrasting effects—bandwagon and leapfrog—relate to organizational Internet diffusion. Bandwagon effects, adopting a technology due to fad and fashion, accelerate adoption but often lead to ineffective technology implementation. Leapfrog effects, however, attenuate adoption and often lead to effective technology use relative to early adopters. Drawing on and combining related Malaysian hospitality studies, this paper illustrates these two effects and extends the literature by showing that early, and late, adoption can relate positively to successful Internet implementation. In addition, the findings complement and question literature suggesting that business websites evolve through predictable linear patterns, and that adopter categories differ in innovation implementation styles.     

互联网平台垄断与低质量陷阱

坚定不移地走高质量发展道路,已经成为各领域发展的共识。然而,随着互联网平台经济的飞速发展,线上市场中的低质量问题也变得愈加突出,相比线下市场,线上市场同类产品不合格率、不达标率、投诉量更高。文章认为平台垄断是低质量陷阱产生的主要原因,超级互联网平台的价格垄断、流量垄断和渠道垄断行为,一方面形成了对低成本实体经济需求的"扩张效应",即低价垄断迫使实体企业降低产品质量成本;另一方面形成了对高质量产品的"挤出效应",即流量垄断带来的高额流量费用,迫使实体企业将大部分资金用于线上市场产品营销,挤出了质量创新投入和渠道垄断形成的巨大规模效应,迫使实体企业将低质低价产品打造成为爆款,保障线上市场销量优势。为此,政府部门需要加大对互联网平台恶性价格竞争的监管和处罚力度,督促互联网平台降低实体企业经营成本,强化互联网平台对实体企业的质量赋能作用。     

互联网发展与创新绩效:三维理论框架和异质性验证

在新一轮科技革命背景下,企业经济活动越来越依赖于互联网,因此探讨中国互联网发展能否有效提升创新绩效,具有重要的理论价值和现实意义。文章构建了互联网发展影响创新绩效的三维理论框架,同时从"质量-数量"二分视角,采用2011-2016年省际面板数据,借助面板个体效应模型对二者相关关系予以实证分析,研究结论如下：（1）互联网通过去壁垒、去中心、去中介,从要素、组织、生产范式三个维度分别经由要素重组、组织变革和供需迭代促进了创新绩效。（2）在全国层面,互联网发展和创新质量间存在U型关系,而互联网发展与创新数量间则表现为倒U型关系,且拐点值存在明显差异。（3）在分区域层面,东中西部互联网发展与创新质量间分别呈现出U型、U型、倒U型关系,与创新数量则均表现为倒U型关系。（4）由于不同省份2016年互联网发展水平分布在拟合线拐点两侧的位置不同,各省份未来政策着力点有所差异。（5）数据驱动、生态网络、用户主导分别与互联网发展深度复合影响了创新绩效,但在显著度上存在差异。综上,应从互联网建设、推广与应用,研判区域异质性,发挥调节变量的正向效应三方面重点突破,最大化互联网创新绩效,促进经济高质量发展。     

工业互联网平台对产业融合影响的实证研究

工业互联网是推进我国经济高质量发展的重要引擎,是制造业转型升级的加速器。工业互联网平台已成为一种新的经济业态和服务载体,并渗透到产业与企业各个层面,深刻影响着制造业产业融合水平。基于2013—2019年省级面板数据,运用面板分位数回归法,分析工业互联网视角下平台经济发展水平与产业融合的关系,揭示工业互联网平台发展水平对产业融合的作用机理,检验制造业升级对平台经济发展水平与产业融合的中介效应。结果表明,工业互联网平台发展对技术融合与生产性服务业和制造业融合的影响不显著,对供应链与价值链融合有显著正向影响。进一步分析发现,制造业升级在工业互联网平台对供应链与价值链融合的影响中具有完全中介效应。研究结果对揭示工业互联网平台、制造业升级和产业融合三者间关系,推动工业互联网平台赋能制造业融合发展具有重要意义。     

烤箱风扇转速及发热管功率对烤鸡翅的影响

为探究烤箱风扇转速及发热管功率对烤鸡翅的影响,本文以肉鸡中翅为主要原料,通过改变风扇转速和发热管功率,研究不同组合条件对烤鸡翅表皮强度的影响,最后以感官评价的方式对测试结果进行验证.结果表明,相对于原样机的参数条件,改变为60％初始转速、130％初始发热功率与或130％初始转速、70％初始发热功率条件,均对鸡翅的表皮强...

Sailing speed optimization for container ships in a liner shipping network

This paper first calibrates the bunker consumption - sailing speed relation for container ships using historical operating data from a global liner shipping company. It proceeds to investigate the optimal sailing speed of container ships on each leg of each ship route in a liner shipping network while considering transshipment and container routing. This problem is formulated as a mixed-integer nonlinear programming model. In view of the convexity, non-negativity, and univariate properties of the bunker consumption function, an efficient outer-approximation method is proposed to obtain an ε-optimal solution with a predetermined optimality tolerance level ε. The proposed model and algorithm is applied to a real case study for a global liner shipping company.     

Hotel roomrates under the influence of a large event: The Oktoberfest in Munich 2012

Surprisingly few studies deal with the implications of large events for hotel prices. We address this issue by modeling hotel prices in Munich under the influence of the Oktoberfest. By utilizing internet data from a metasearch provider for check-in dates prior to and during the Oktoberfest 2012, it is analyzed how the event affected the daily price level as well as price differentials between hotels. In general, average hotel prices are very volatile over time. Apparently, Munich hotels tend to set prices according to expected demand and vary those depending on the day of the week during the event. Ceteris paribus, roomrates are highest on Oktoberfest Friday and Saturday nights, followed by Oktoberfest weekdays and Oktoberfest Sunday nights, but there is a general and strong price-raising impact. Prices differ across hotels mainly due to the star category attributed to a hotel and the proximity to the event. Both price premia are time-dependent.     

Critical resource: An institutional economics of the Internet addressing-routing space

This paper links the analysis of IP address policy to the established vocabulary and concepts of institutional economics. Internet addressing and routing are usually discussed in technical terms, yet embedded in this highly technical discourse are a number of critical economic concepts, such as scarcity, externalities, common pool resources, tragedy of the commons, and conflict over the distribution of costs. To solve these problems, governance institutions native to the Internet have evolved. Yet despite the centrality of addressing and routing to Internet governance, there is very little research literature that bridges economic, institutional and technical discussions of IP addressing and routing. This paper connects the techno-economic discussion to analysis of institutions and governance arrangements.     

An acceptance model for an Internet protocol television service in Korea with prior experience as a moderator

This study examines the effect of users' prior experience on the adoption behaviour in the Internet protocol television (IP TV) service domains. This article proposes a new acceptance model for an IP TV service considering the moderating effect of experience and verifies the model with an empirical study. Respondents are classified into either experienced or inexperienced groups according to their prior experience with the IP TV service. The results indicate that motivational factors used in our study affect behavioural intention. In addition, this study shows that the influence of extrinsic motivational factors on the behavioural intention are stronger for the experienced group than the inexperienced group and the influence of intrinsic motivational factors on the behavioural intention are stronger for the inexperienced group than the experienced group. This article concludes with study implications, as well as limitations and future research directions.
