An Investigation of Brand-Related User-Generated Content on Twitter

The big data of user-generated content (UGC) on social media are laden with potential value for brand managers. However, there are many obstacles to using big data to answer brand-management questions. This article presents a framework that automatically derives latent brand topics and classifies brand sentiments. It applies text mining with latent Dirichlet allocation (LDA) and sentiment analysis on 1.7 million unique tweets for 20 brands across five industries: fast food, department store, footwear, electronics, and telecommunications. The framework is used to explore four brand-related questions on Twitter. There are three main findings. First, product, service, and promotions are the dominant topics of interest when consumers interact with brands on Twitter. Second, consumer sentiments toward brands vary within and across industries. Third, separate company-specific analyses of positive and negative tweets generate a more accurate understanding of Twitter users' major brand topics and sentiments. Our findings provide brand managers with actionable insights in targeted advertising, social customer relationship management (CRM), and brand management.     

Do cross-border mergers and acquisitions increase short-term market performance? The case of Chinese firms

Despite the new momentum in cross-border mergers and acquisitions (M&As) by emerging market firms, we have a limited understanding of the impact of these activities. Drawing on signalling theory and the institution-based view, this paper examines the extent of stock market reactions to the announcement of cross-border M&A deals, based on an event study of a sample of Chinese firms during the period 2000–2012. The findings indicate that the announcement of cross-border M&As results in a positive stock market reaction; this effect is more significant in the mainland Chinese stock markets (Shanghai and Shenzhen) than that in the Hong Kong market. The shareholders of Chinese firms that acquire a target firm in a host country with a low level of political risk gain higher cumulative abnormal returns than those firms targeting companies in countries with a high level of political risk. The shareholders of Chinese state-owned enterprises experience lower abnormal returns compared with those of Chinese privately owned firms when engaging in cross-border M&A deals.     

新疆连片特困地区少数民族农户贫困影响因素分析

[目的]少数民族连片特困地区的贫困问题是我国新时期扶贫攻坚的难点和重点。深入剖析该区域少数民族农户致贫因素,为新时期精准扶贫精准脱贫提供参考。[方法]基于实地调研数据,利用Logistic模型,从户主特征、家庭特征、村庄环境特征等3个方面对新疆连片特困地区少数民族农户贫困的影响因素进行深入研究。[结果]户主的性别和受教育程度、家庭成员中熟练说国语人口所占比重、兼业情况、是否参与农业合作组织、家庭成员是否残疾或重大疾病、人均耕地面积、是否通公共交通车均对贫困产生了重要影响,与预期一致;户主年龄、农户家庭中劳动力所占比重、未成年人口所占比重、离县城的距离、有无自然灾害对贫困的影响均没有通过统计上的显著性检验,与预期假设不符,主要是"一户一策"的精准脱贫政策及惠农工程起到了重要作用。[结论]未来应从提高贫困人口的自我发展能力和实现对贫困人口精准识别精准帮扶两个方面提高片区的脱贫成效。     

物化生化联合工艺处理难降解有机化工废水

利用CS药剂—铁炭还原—水解酸化—SBR组合工艺处理难降解有机化工废水,并对试验现象和结果进行了分析。试验结果表明,组合工艺最优参数为CS试剂投加200mg/L,铁炭还原铁粉及炭粉质量比1∶1,水解酸化池HRT9h,SBR工艺采用非限制性曝气的运行方式,周期为进水曝气5.5h,沉淀1.5h,搅拌时间0.5h,排水和闲置0.5h。试验结果表明,经该工艺处理后出水水质达到《污水综合排放标准》(GB8978—1996)一级排放标准。

陕西省土地储备中政府、农民权益得失评价

随着1996年上海等地开始借鉴国外经验,摸索土地储备制度的同时,陕西省各地政府也于2002年前后纷纷建立了专门的土地储备机构并出台了相应的土地储备制度。土地储备制度是政府调控土地和集约化用地的主要手段,制度在实施过程中给相关权益主体造成了一定的利益得失。结合陕西省政府及农民等土地储备权益主体在土地储备过程中公信力和征地补偿权益得失的分析,提出创新土地融资方式和完善土地储备制度,促使政府和农民的权益达到损失最小化和收益最大化。     

人力资本与R&D如何影响全要素生产率——基于中国大中型工业企业的经验分析

基于2000～2007年中国大中型工业企业的行业数据,本文利用投入—产出表将行业间R&D溢出区分为前向和后向,使用数据包络方法计算各行业的Malmquist生产率指数,并将其分解为技术效率和技术进步。在控制行业技术特征和所有制结构的条件下,考察了人力资本、R&D、前向和后向R&D溢出以及人力资本和R&D及R&D溢出之间的交互作用对全要素生产率、技术效率和技术进步的影响。最后,还比较了这种影响在高技术产业与低技术产业之间的异同。
