Drivers and barriers to cross-border e-commerce: Evidence from Spanish individual behavior

This paper explores the determinants of the individual's decision to perform cross-border e-commerce (CBeC). The European Union (EU) is especially interested in the promotion of CBeC because it is an important tool in its strategy to achieve the Digital Single Market in Europe. In this paper official data is used from a representative survey of 16,209 individuals on ICT usage by households and individuals that was carried out in Spain by the National Institute of Statistics (INE) for the year 2016. Using a standard neoclassical utility maximization framework, and logistic regression techniques, the results show that being a male is positively related to the probability of practicing CBeC. Education is positively and significantly related to the probability of being involved in CBeC with EU countries. Computer and Internet Skills are significant and positive factors in explaining CBeC (either with EU countries or with the rest of the world). The variable “how often the consumer sees other customer reviews before buying online”, has a positive effect. Foreign nationality also increases the likelihood of using CBeC. To promote CBeC in Spain measures towards developing digital skills, Internet trust and use of online information reviews of goods and services are discussed.     

网红直播打赏收入影响因素的实证研究

网红经济是一种新型经济模式,打赏也成为消费者支配财富的一种新型方式。探索打赏背后的影响因素和经济规律不仅对网红娱乐平台的可持续发展至关重要,且可为相关监管规定的落实和完善提供有益参考,有助于引导“网红经济”持续健康发展。当前学术界尚缺乏探索网红主播打赏收入影响因素的研究,本文获取了5家网红经纪机构中41位游戏类网红主播每场直播的收入与直播时长数据,研究发现:首先,网红主播的直播收入和观众打赏强度均与直播时长显著正相关,这意味着网红主播对观众的更多娱乐陪伴使其获得了更多的打赏收入;其次,头部打赏者对网红主播的打赏使非头部打赏者的打赏强度更大,这表明观众对网红主播的打赏存在“羊群效应”。     

国际粮食价格危机的农业政策根源

2007～2008年世界粮食作物价格的急剧上涨的原因很大程度上要归结于各国长期的农业政策。从农业贸易看,农业贸易限制程度远远高于工业贸易,这不利于粮食作物产量在全球的分配;从农业生产看,发达国家和发展中国家完全不同的政策导向,导致了全球农业生产的低效率。应对世界粮食价格飙升最有效的长远机制是全球粮食贸易自由化,减少甚至取消贸易扭曲的农业生产和贸易政策。     

剔除食品和能源的核心通货膨胀度量方法

文章以2000年1月至2015年5月月度同比CPI分类价格指数时间序列数据为基础建立协整关系和 共特征向量检验。实证分析表明我国CPI分类指数时间序列之间长期存在共同趋势,短期存 在共同周期。因此,在我国使用剔除食品和能源的核心通货膨胀测算方法是不合理的。本文 进一步提出我国中央银行在制定货币政策时,应同时关注官方公布的核心通货膨胀和通货膨 胀,以免使货币政策对食品和能源价格上涨反应不足或反应过度,以及提出我国核心通货膨 胀的测算还应关注CPI结构的建议。     

未来房地产网络营销在线交易模式

当前,我国电子商务技术得到了迅猛发展,房地产网络营销是必然的趋势,部分房企试水房产电商并建立独立的区域性体系,却收效甚微,弊端与瓶颈凸显。通过对我国房地产网络营销宏观和微观上现存问题的分析,提出未来房产的“整体－区域”在线交易模式的要点以及构建。首先,在政府引导下,房地产企业和第三方机构以购房者为中心,构建出四位一体的全国整体性营销信息平台体系;其次,在此基础上建立由企业、购房者、第三方机构组成的区域性在线交易三角关系;最后,诱导更多的企业进入,进而构建出有效的房产在线交易模式。     

Redefining Local Government Roles In Public Services

County officials in the seven-county metropolitan area of the State of Minnesota's Twin Cities of Minneapolis and St Paul were seeking to redefine county roles in service delivery. This article reports on a process model that was piloted on two services. The model was commissioned by officials; was based upon and informed by literature and comparative experience; began with an examination of functions performed; involved participants in focusing the study; was context-focused; and involved local stakeholders in projecting the implications of alternative county roles. These characteristics complicated the research management process because the process took more time, involved more actors, and required more coordination than traditional research. However, having stakeholders identify alternatives and bring factual material to the process was critical to the success of the model and including the comparative and contextual research both strengthened the policy conclusions and improved the probability of their adoption and implementation. A case of a Minnesota county that followed the model in an effort to reform water governance within the county illustrated adoption of the approach. The stakeholder analysis process was previously applied in Africa, China and Southeast Asia and the model should be applicable to a wide range of settings and problems.

浅析影响食品饮料中糖分检测的因素

糖类是食品饮料中的重要组成部分。糖类物质是食品工业的主要原料和辅助材料。食品饮料中的糖分的高低不仅影响产品的口感、风味,而且会影响到产品的保质期。因此,食品生产企业必须严格控制食品饮料中的糖分的高低并且能够有效地检测出它的含量。本文从食品饮料中糖分的检测方法出发,主要论述了食品饮料中微量糖分检测的技术要领及其检验中的关键步骤,以实用性强,检测结果准确可靠为宗旨。特别是对于加工低糖、无糖食品及干型、半干型葡萄酒、黄酒、果酒的企业来说,提供一种检测技术以指导企业的生产。
