More than what meets the eye: Understanding the effects of poly-contextual cues in online fashion retailing

While previous studies have examined the presence (vs. absence) of contextual cues or the product-context fit, the effect of multiple cues (poly-cue) remained underexplored. In response, this study investigated the effects of poly- (vs. mono-) cues on the valuation of a product and the underlying mechanism behind these effects. Findings suggest that a poly-cue increases the product valuation via increased consumption vision (Study 1–3), which was pronounced for global processors (Study 2) and attenuated for a product with low contextual versatility (Study 3). This study provides actionable insights for online retailers as well as enrich the relevant literature.     

劳动力成本对中国加工贸易规模及转型升级的影响

本文以中国《最低工资规定》的出台作为准自然实验,基于2000-2013年企业层面微观数据,采用双重差分法系统研究了劳动力成本上升对企业加工贸易规模及转型升级的影响。本文发现,劳动力成本上升虽然缩小了企业加工贸易规模,但通过倒逼机制促进了加工贸易企业转型升级。进一步的机制检验表明,劳动力成本上升促进了加工贸易企业增加固定资产投资、扩大研发创新和在职培训的投入力度、提高生产效率,进而推动了企业加工贸易升级。最后,本文还在城市层面研究了劳动力成本、资源配置与加工贸易升级的关系,结果表明,出口市场份额再配置是劳动力成本上升促进城市加工贸易升级的重要途径:一方面,劳动力成本上升促进了出口市场份额向竞争力较强的存续加工企业再配置,另一方面,劳动力成本上升加速了低竞争力加工企业退出。本文一方面丰富了评估最低工资经济效应的研究,另一方面有助于理解中国加工贸易转型升级背后的驱动因素。     

无限冲击响应数字滤波器设计软件

<正> 经营机制必须转换企业活不活,关键在于企业经营机制好不好。当前,我国许多企业经济效益滑坡,主要就是因为旧的企业经营机制管理层次过多,人浮于事现象严重,市场应变力不强等因素造成。相反,从当前实际情况看,我国一些非国营企业,包括乡镇企业、“三资”企业、私营企业,因为其本身不但是自主经营、自负盈亏,而且生产经营活动基本上是由市场调节,同市场和市场经济在客观上已经结合在一起,特别在治理整顿期间,他们不但经受住经济紧缩的考验,而且通过自觉优化结构,提高技术质量档次,反而发展得更好了。究其原因,就是因为他们的企业经营机制已经基本解决了。由此可见,转换企业经营机制已经势在必行,早转晚转都要转,早转早主动,晚转要被动,不转要受穷。

人民币汇率变动与劳动力技能偏向效应——来自中国微观企业的证据

本文基于我国“民工荒”和“大学生就业难”并存的特殊背景,在“劳动力异质性”前提下研究了人民币汇率变动的技能偏向效应及其对企业雇佣结构的影响,并检验了加工贸易和竞争模式的调节作用。利用2004和2008年经济普查数据所提供的技能细分劳动力信息,结果发现:(1)汇率升值通过“出口收益渠道”负面影响了技能劳动力雇佣占比,而通过“进口中间品渠道”对其产生正面促进作用;(2)随着加工贸易占比升高,“进口中间品渠道”的正面影响持续下降,而汇率“出口收益渠道”的负面影响在加工贸易占比超过40%后才逐步下降;(3)竞争模式亦具有调节作用,价格竞争型企业的雇佣结构受到外汇风险暴露指数的负面影响更强,这反映出“质量竞争”模式的积极作用。     

保障贸易政策稳定促进对外贸易持续健康发展

为了促进经济结构调整和产业升级、转变经济增长方式,自2005年5月以来,中国相继实施了一系列取消或降低出口退税率、出台禁止和限制类加工贸易产品清单等政策措施。虽然当前有关贸易统计数据还没有准确反映出中国对外贸易形势的变化,但是东部地区已开始面临中小企业经营困难、就业压力进一步增大、部分外商投资企业撤离等问题。本文认为,这主要是出口退税政策不稳定和"两高一资"产品涉及面过广等原因造成的,建议暂不宜出台新的贸易政策和暂缓执行某些影响重大的贸易政策。     

产业政策促进全球价值链升级的有效性研究——基于出口加工区的准自然实验

本文利用我国出口加工区(EPZs)成立之初所实施的“主导产业”扶持政策构造“准自然实验”,实证检验了该政策对于企业全球价值链(GVC)升级的效果并进一步探讨政府实施产业政策的有效性,发现:(1)EPZs的“主导产业”政策对我国出口企业GVC升级存在负向影响,而这种负向影响在多重稳健性检验下均成立;(2)异质企业视角下考察产业政策对GVC升级的影响发现在国有资本份额较大的企业和重工业企业中产业政策对GVC升级的负向影响尤为明显;(3)对EPZs的“主导产业”政策发挥作用的前提进行检验,发现在比较优势较强的行业,产业政策对GVC升级的负向影响不明显甚至存在正向影响;同时,在错配程度较低的行业负向影响也不明显。由此本文认为,政府在推动GVC升级方面应当“有所作为”,但也不能“无所限制”,即产业政策要针对比较优势“精准定位”,但也应当以不造成资源严重错配为前提。     

价值链视阈下广东加工贸易产业转型升级的战略取向

Sustainability and multifunctionality of protected designations of origin of olive oil in Spain

Agrarian systems provide sociocultural and environmental externalities, which contribute to the sustainability of rural areas. The aim of this article is to analyse the sustainability of some Spanish olive oil Protected Designations of Origin (PDO) through multicriteria techniques (Analytical Network Process), taking into consideration different farming systems. The analysis has been made through ten criteria grouped in three clusters: economic, environmental and socio-cultural and asked experts. This was done first to rank the criteria and second in terms of what type of farming system achieves these criteria better. According to the results, there is a high level of consensus regarding the criteria ranking and the way that farming systems contribute to agrarian multifunctionality and sustainable development, despite the different characteristics of PDOs. In all cases, organic farming is the best, followed by integrated farming, when achieving economic, environmental and socio-cultural criteria, except for Estepa (where integrated farming is preferred for the economic and socio-cultural criteria). Conventional farming is placed in third position when achieving all functions, except for the environmental criteria, for which abandonment is preferred to conventional farming in all PDOs. Multifunctionality and sustainability are maximized by a combination of farming systems: about 40% organic, 35% integrated, 20% conventional and 5% crop abandonment.The results of our model regarding the combination of farming systems are similar to the actual situation in the PDOs studied, and, more important, this has been achieved thanks to the PDO institutions. Good local institutions contribute to improve the sustainability of rural areas by encouraging innovation and entrepreneurship (especially in PDOs, triggered by Origin Designation Regulator Councils) and a European level, by paying farmers for externalities.     

Advertising value and advertising processing

Advertising value research is rooted in the view that advertising messages are potential communications exchanges between advertisers and consumers. Since some level of processing effort on the part of receivers is necessary for successful exchanges to occur, it is proposed that advertising processing decisions are based on initial, spontaneous, categorical evaluations that combine to form an expected advertising value (EAV) assessment. If sufficiently positive, individuals devote additional processing effort to the advertisement and more detailed ad-related factors become the focus. Once processing ends after some or all of an advert has been taken in, an evaluation of whether or not the effort was actually worthwhile - designated as outcome advertising value (OAV) - should be a measurable outcome. Factors that account for OAV and its relationship to attitude-toward-the-advertisement (A ad ) are also discussed.
