对南海国际争端的经济学解析

我国地处东亚的中心,是一个陆海大国,与周边各国有着漫长的边界线,地缘环境非常复杂,形势十分严峻。近些年,随着我国综合国力的逐渐壮大,以及国际格局和地区形势的变化,我国的周边安全环境进一步缓和。而南海,其独特的地理位置和战略位置决定了它的重要性。当今的南海格局被称作六国七方,南海争端涉及到诸多国家的政治、经济利益,主权、领土的争端以及运输通道和能源安全等问题。本文从博弈学和经济学的角度分析南海现状的成因,并就解决南海问题的政治经济对策进行探析。     

全球城市的经济地位研究

全球城市成为认识全球经济的一个视角,越来越多的研究聚焦全球城市,这既反映了世界经济的新变化,也反映了城市发展的新变化。经济全球化的"分离"和"集聚"打造了全球城市。信息技术成为全球城市的技术基础。全球城市网络成为全球城市的外部条件。全球公司占据全球城市的关键地位。全球城市的意义在于服务于全球经济,其服务的属性是生产性服务,主要形式是商务服务和金融服务。全球城市驱动全球经济,全球城市集聚一国的经济能量,全球城市应该成为中国经济的一个方向。全球城市已经成为北京上海的发展目标。     

Incentives to move up: Effects of pay gaps between levels on employee performance

Employees of a certain rank are motivated by the pay gap between them and the levels above (upward comparison), and the pay gap between them and the levels below (downward comparison). In some cases, employees face multiple upward comparisons such as immediate and subsequent upward comparisons. We hypothesise that upward comparison matters more than downward comparison, and in the case of multiple upward comparisons, the immediate one matters more than the subsequent ones. We also hypothesise that the pay gap effect resulting from the upward/downward comparison ought to be non‐linear in that performance increases with pay gap size at a decreasing rate. The results from two empirical studies, namely, a longitudinal field study and a laboratory experiment, largely support our hypotheses.     

Organisational regulatory legitimacy,entrepreneurial orientation,and SME innovation: an optimal distinctiveness perspective

The optimal distinctiveness perspective argues that firms face competing pressures to be both ‘like’ and ‘different from’ their peers. On the one hand, institutional scholars assert that firms need to be similar to peers in order to gain legitimacy. On the other hand, strategy scholars insist that firms need to strive to be different to gain competitive advantage. In order to enrich the optimal distinctiveness perspective, the present study builds a conceptual model that addresses the relationships among organisational regulatory legitimacy, entrepreneurial orientation, and SME innovation under the context of China’s transition economy. Our empirical results show that organisational regulatory legitimacy has an inverted-U relationship with SME innovation. Further, entrepreneurial orientation strengthens this inverse-U shaped relationship. That is, entrepreneurial orientation magnifies both the positive and the negative effect of organisational regulatory legitimacy on SME innovation. This study echoes to the call to conduct broader optimal distinctiveness research by integrating institutional theory and strategic management. Furthermore, our findings provide new evidence for the strategic balance perspective of optimal distinctiveness.     

区域规划的必要性与困境:从英格兰废止"区域空间战略"所引发的思考

面对全球经济衰退和地方可持续发展的严峻挑战,英国政府自2010年以来,为解决规划体系存在的层级过多、官僚、效率低下等弊端,通过重构空间规划体系,调整规划和发展之间的关系,实现经济的复苏.英国空间规划体系改革废止2004年《规划和强制收购法》所设立的法定"区域空间战略",区域协调出现问题.区域间的协作长期以来就是空间规划的一个难题,解决这个难题有两种模式,一个是政府行政的模式,另一个是市场和经济的模式.由于英国 自身具有自由裁量权特征的规划体系,区域间各方的合作十分重要,但以什么机制开展协作一直未能解决.这次的改革废除了区域规划和区域机构,希望以市场的手段进行协调、平衡区域间各方的利益在理论上具有操作性,但至今为止的实际运作并不理想.     

Does economic policy uncertainty raise corporate precautionary cash holdings? Evidence from China

Using China as the research setting, this paper investigates the relationship between economic policy uncertainty and corporate precautionary cash holdings. Empirical results show a U-shaped relation between economic policy uncertainty and corporate precautionary cash holdings. Empirical analysis, in terms of ownership structure, firm size, corporate competitiveness and geographical location, further shows that (i) the effects for economic policy uncertainty in both state-owned and non-state-owned enterprises are significant, but the effect is stronger for state-owned enterprises; (ii) such significant effect is also found more strongly in small and medium-sized enterprises and highly competitive enterprises; and (iii) the effects for eastern, central and western China are all statistically significant, but the effect is strongest for eastern China.

Social media bots and stock markets

This study examines the link between information spread by social media bots and stock trading. Based on a large sample of tweets mentioning 55 companies in the FTSE 100 composites, we find significant relations between bot tweets and stock returns, volatility, and trading volume at both daily and intraday levels. These results are also confirmed by an event study of stock response following abnormal increases in the volume of tweets. The findings are robust to various specifications, including controlling for traditional news channel, alternative measures of volatility, information flows in pretrading hours, and different measures of sentiment.
