中国城市服务业区域间溢出效应与反馈效应分析

本文首先通过区域间投入产出表,分析了中国东北、东部、中部、西北和西南五大地区服务业的溢出效应,然后通过两区域投出产出模型衡量服务业地区间的和地区内部相互的反馈效应。研究发现：东部地区是区域间经济交流的最大收益者,所受到的溢出效应最大;而西北地区是最小收益者,所受到的溢出效应最小;沿海地区区域内的服务业联系要强于内地;内地对沿海的服务业外溢效应要远远高于沿海对内地的;与内陆相比,沿海地区服务业的发展更容易受到外界影响,同时商业运输业比其它服务业的外向性特征更加突出;服务业的各种效应程度小于工业,而大于农业。     

双顺差下中国货币政策有效性的实证检验

通过对1994年以来中国货币政策目标、货币供给以及外汇储备等几个指标的协整检验和向量误差修正模型分析,本文认为双顺差条件下,货币供给内生性加强,货币政策虽然短期有效,但有效性程度不高,长期货币政策基本无效。鉴此,应防止热钱冲击、进一步放宽人民币汇率的波动幅度、改善汇率形成机制、加快利率市场化进程,以提高货币政策有效性。     

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.     

中国式分权、转移支付与居民收入不平等

本文首先采用基尼系数对我国城乡、城镇和农村居民收入不平等程度进行重新测度,然后以政府转移支付为门限变量建立面板门限回归模型,对财政收支分权与居民收入不平等之间关系进行实证检验,结果发现:一是财政收入分权与收入不平等显著负相关,财政支出分权与收入不平等显著正相关;二是财政收支分权对不同类型收入不平等的作用效果存在较大差异.其中,无论是财政收入分权抑或支出分权对收入不平等的政策效应大小依次是城镇居民＞农村居民＞总体居民;三是政府转移支付在不同区制对居民收入不平等的影响呈现显著地非线性特征.即从相对较低的第一区制跨入较高的第二区制时,转移支付对居民收入不平等的影响由负转变为正.本文以上研究结论不仅对于全面构建央地新型政府间财政关系,还可以为促进公平收入分配提供理论依据与决策参考.

从广场协议看日元升值的教训及启示

上世纪80年代在世界经济不平衡的环境下,美日之间进行了一系列的政策协调,日本付出了惨痛的教训。这一段历史表明,以汇率调控为主的宏观政策,在调整世界平衡方面仅有短暂的微弱作用,但代价昂贵且不公平。汇率升值对贸易结构有深刻影响,在增长动力减弱的情况下,处理不当容易引发泡沫。应把握好金融自由化、宏观政策、监管及改革之间的关系。
