马克思的世界观与《资本论》的方法论

在一个语言模式、话语体系、文化形态越来越决定资源配置、利益机制、发展方向的时代,中国的发展不仅需要科学发展观来引领,而且需要科学历史观和科学世界观来提升。在这里,科学的基本含义是以人的批判、探索、发现、创造等活动为基本内容的社会实践,"以人为本"的基本含义是以全人类、或大多数人或人民大众的利益为本。马克思的世界观与《资本论》的方法论本质上是彻底的"以人为本"的世界观和方法论。     

基于大数据的跨境进口零售电商平台的网络舆情分析

从消费者视角出发,从三大跨境电商平台采集消费者评论,对其进行定量和可视化分析,发现产品质量和物流问题是消费者给予积极和消极情绪评价的关键因素,而导致大规模海外网购的主要原因则在于产品质量,但消费者对所购产品的质量并非完全满意。因此,要加强对跨境进口零售商品的监管,及时公布跨境购买境外商品的信息,同时要培育购买国货的消费文化。     

多维视野观照下的话语与权力

语言研究中的话语不仅是传达意义的符号系统,它还与社会实践存在密切的联系,话语的背后是社会结构中的权力。文章从多学科的角度研究不同学术视野下话语与权力这一重要命题的代表性研究现状。     

金黄色葡萄球菌蛋白A在大肠杆菌中的自诱导表达以及单克隆抗体的制备

利用大肠杆菌表达金黄色葡萄球菌蛋白A,根据大肠杆菌密码子偏好性对金黄色葡萄球菌蛋白(SPA)基因进行密码子优化。SPA基因插入p ET28a表达载体中,利用自诱导培养基诱导SPA表达,表达量达8.2 mg/L。通过Ni亲和层析纯化SPA蛋白,纯度达到95%。纯化的SPA蛋白免疫小鼠制备单克隆抗体,间接ELISA法检测抗体效价,抗体效价可达1∶40000,采用Protein G亲和层析纯化SPA单抗,纯度达98%。纯化后的SPA单抗检测与食品中常见的致病菌无交叉反应。结果显示,SPA单抗特异性良好,与其他致病菌无交叉反应。     

中国制造业资本偏好水平评价

构建了包括劳动密集型产业和资本密集型产业的政府目标函数,利用2005—2012年中国省际面板数据,测算了劳动密集型产业和资本密集型产业的权重区间。研究结果表明:中国政府目标函数中资本密集产业部门的权重介于0.564~0.623之间,资本密集型产业部门的权重显著大于劳动密集型产业部门;政府更重视资本密集型产业部门的福利。     

银行风险偏好对企业发展影响的实证研究

从行业层面和企业层面实证研究了银行信贷选择对行业和企业发展的影响。结果发现:在行业层面,银行偏好于固定资产比率较高的行业,因此在信贷资源较为紧张的地区,固定资产比率较高的行业会发展得较好,可见长期内银行选择会影响一个地区的产业结构;在公司层面,银行偏好于行业中固定资产比率较高的企业,而企业为了获得信贷资源也会调整其发展策略,倾向于积累固定资产。指出:中国应该大力发展非银行融资渠道,减弱金融系统对经济发展的扭曲。     

Co‐movements in commodity prices: a note based on network analysis

This article analyses co‐movements in a wide group of commodity prices during the time period 1992–2010. Our methodological approach is based on the correlation matrix and the networks inside. Through this approach we are able to summarize global interaction and interdependence, capturing the existing heterogeneity in the degrees of synchronization between commodity prices. Our results produce two main findings: (a) we do not observe a persistent increase in the degree of co‐movement of the commodity prices in our time sample, however from mid‐2008 to the end of 2009 co‐movements almost doubled when compared with the average correlation; (b) we observe three groups of commodities which have exhibited similar price dynamics (metals, oil and grains, and oilseeds) and which have increased their degree of co‐movement during the sampled period.     

Understanding Business Relationship Management in China： A Power and Leverage Perspective

This paper examines whether a power and leverage perspective, successfully applied to analyse extended buyer-supplier relationships in a western context, can be used to analyse business relationships in China. A single embedded case study is presented in this paper and a power and leverage approach is used to analyse business relationships. The power and leverage perspective is applicable for investigating buyer-supplier relationships in a Chinese cultural context. However, in this context using power as coercion is an extremely counterproductive relationship management strategy, which can draw both buyers and suppliers in to a ＂no-win＂ or negative sum situation. The findings are based upon a single case, which makes drawing generalisable conclusions more difficult. In addition, although every effort was made to limit the subjectivity of the power and relationship analysis, researcher interpretation of the data was required. In the Chinese business context, it may not be advisable to manage any relationships in an arms-length manner. Chinese business networks are centred on less explicit or formal power relationships and therefore companies that have learnt the rules of the game of exchange in the west need to modify their approach in China. This work extends the understanding of buyer-supplier relationships and provides additional empirical evidence validating a power and leverage perspective. In addition, the paper provides the first assessment of whether this approach can be used in a non-western context without significant modification.     

20世纪前期买办职业收入分析

20世纪前期，买办的职业报酬制度达到成熟和完善。买办的职业收入主要由薪金和佣金构成，还有一部分被外商默许的暗中收入。佣金是多数买办的主要收入，是买办经纪人身份的体现；薪金是买办与外商雇佣关系的一种象征。买办收入的复杂挂还在于不同行业的买办收入来源不一，且差距较大。
