Value networks and two-sided markets of Internet content delivery

The volume and importance of content is increasing in the Internet, whereas the ability of the Internet architecture to scale to the growing demand for transport capacity is uncertain. Even though the natural growth in the demand continues, the growth in traffic volumes can be limited by reducing unnecessary content copying and redundant transportation of the same content. Information-centric networking (ICN), featuring globally unique naming of content and optimized in-network caching, has been suggested as a potential future solution to significantly reduce unnecessary traffic, but its economic feasibility has not been widely studied. This paper evaluates the economic feasibility of ICN by using the two-sided markets theory to analyze four Internet content delivery models: the client-server model, content delivery network (CDN) model, peer-to-peer model and ICN model. Value networks and two-sided markets of these content delivery models are identified in the process. The results suggest that content providers can be willing to pay for the lower delay of content delivery in ICN, if ICN can solve its coordination problems related to cost-allocation, contracting, quality of service guarantees, and content usage statistics. These incentive challenges are essentially the same as in-network web caching originally faced and could not overcome. Internet access providers may also consider investing in the deployment of ICN due to reduced interconnection costs. However, the ICN model may require a revenue-creating business model to make it more attractive to Internet access providers than the CDN model that provides similar cost savings.     

黑龙江邮政速递物流有限公司市场营销策略分析

随着对外经济的快速发展,快递行业迅速进入发展的黄金时期。由于快递服务业的对外开放,以邮政速递物流公司为首的国有快递企业正遭受国际快递巨头、非邮政国有快递公司、民营快递公司的重重打击,给邮政速递公司带来巨大冲击。国有快递企业的的市场份额正不断下降,不容乐观。     

后疫情时代下新冠肺炎疫情对中国服务经济影响 ——基于多期双重差分模型的研究

本文使用中国31个省、直辖市和自治区2019年6月~2020年9月共16个月的月度面板数据,采用多期双重差分(DID)方法,分别就新冠肺炎疫情对服务业中的快递行业、金融行业、公路货运行业和进出口行业的影响展开分析,研究结果表明:疫情对快递行业和金融行业的影响有显著正向影响,对进出口企业和公路货运行业有显著负向影响。进一步,采用三重差分模型进行地区异质性与禀赋异质性检验后发现,疫情对东部地区的快递业影响不显著,对中西部地区的快递行业收入有显著正向影响;疫情对东部沿海地区的进出口总额有显著负向影响,对中西部进出口总额影响不显著;疫情对东部、中西部金融存贷款的影响均显著为正;疫情对东部地区公路货运量的影响显著为负,对中西部的影响显著为正。疫情与2019年卫生人员三重差分模型显示,对快递行业收入的影响显著为负;对公路货运量和进出口影响不显著;对金融存贷款影响显著为正。疫情与2019年人口资源禀赋三重差分模型显示,对快递行业收入、进出口总额和金融存贷款影响显著为正;对公路货运量影响不显著。

国内连锁超市的核心竞争力分析

连锁超市核心竞争力是指连锁超市所拥有的超越其他零售业态或其他企业能使自己保持长期竞争优势并获得稳定发展的能力。在后WTO时代,中国的连锁超市若要在国内同行的竞争和外资洋超市的冲击中求得生存和发展,必须尽快提升自己的核心竞争力。核心竞争力是连锁超市生存和发展的基础,为提高核心竞争能力,连锁超市必须对影响其核心竞争力的因素进行分析,在分析的基础上做出正确的决策。本文分析了连锁超市在中国的发展现状,核心竞争力的影响因素,以及在目前环境下该如何提升国内超市的核心竞争力。     

管线钢及输送管的变形能力

综述了管线钢及输送管的变形能力及相关指标。输送管的变形能力可用屈曲应变表示,一般具有Round-house形应力-应变关系、均匀塑性延伸率高、形变强化指数n高、屈强比低的管线钢的变形能力较高,组织通过影响应力-应变关系和屈强比影响变形能力,另外D/t增加变形能力提高。变形能力对工作于地震及地质灾害多发地区的埋地式管线的安全是非常重要的,国外已有相关产品,我国应加快这方面的研究。     

Online retail experience and customer satisfaction: the mediating role of last mile delivery

ABSTRACT

For various industries worldwide, recent years have been defined by the remarkable growth of e-commerce. Enabled by the Internet, retailers can reach more customers, spread much further in the distribution chain, and optimize their resources. In the new market environment, customer experience has become a source of competitive advantage. This study investigates the role of last mile delivery in the customer’s e-retail experience. A quantitative methodology was used, which incorporated a survey that was conducted in Sweden and measured participants’ most recent e-retail experience. The results indicate that the last mile delivery experience mediates the relationship between the customer’s perception of the online shopping experience and customer satisfaction. These conclusions provide ground for further thorough investigations of the role of last mile delivery in the e-retail context and support e-retailers in increasing their customers’ satisfaction.
