高技术企业的权变治理、管理者更替与企业永续发展

高技术企业的治理与规范化公司的治理存在很大的差异,甚至是本质上的差异。这种差异主要来自于高技术企业的人力资本价值和团队合作价值。但从企业长期发展来看,高技术企业必须平衡权威治理和企业永续发展的关系问题。本文运用企业权力主体竞争力模型分析高技术企业控制权结构,剖析了高技术企业的“两人治理结构”现象,揭示出保持高技术企业永续发展的两大主题——权变治理和管理者更替问题。

Pricing mortgage insurance contracts under housing price cycles with jump risk: evidence from the U.K. housing market

Previous studies have investigated the determinants of housing price cycles in the housing market; however, we observed the phenomenon of housing price jumps in the 2007 subprime crisis. This paper presents a discussion on the housing price cycle and abnormal price jumps to describe the behavior of housing prices in the United Kingdom. The empirical results show that the impact factors of housing cycles are market risk and the switching factor. Furthermore, the impact factors of jump risks include the bursting of the housing bubble and financial crises. Therefore, in this paper, we employ the Markov switching model with jump risks to value the MI contracts and analyze the influences of housing price cycles, jump risks, risks of market interest rate, and the prepayment risks on MI premiums. The results of sensitivity analysis show that more volatile housing price index returns, as well as longer periods of higher volatility in housing prices, raise MI premiums. Moreover, the MI premium is positively related to the absolute value of the average jump amplitude and the shock frequency of abnormal events. There is the tradeoff between the market interest rate and the prepayment risk. The influences of market interest rate are different on MI premium with/without prepayment risks.     

房产税改革、经济增长与金融稳定

本文通过构建嵌入税收楔子、住房抵押融资约束和银行监管约束的多部门DSGE模型,考察了面向家庭和企业两大住房持有主体实施统一税基评估率和差别税基评估率的房产税政策对经济增长和金融稳定的长期影响,并比较分析了两类房产税改革方案对经济波动和金融风险的短期影响。研究发现:在长期,房产税通过对房价的"抑制效应"和对住房的"再分配效应",有利于促进经济增长,提振居民消费,并能有效抑制家庭杠杆的过度上升和资产泡沫风险。在短期,征收房产税不会加大系统性金融风险的冲击强度,因而不会对维护金融稳定产生不利影响。不同的房产税政策对经济增长和金融稳定的影响存在差异,相较统一税基评估率的房产税,差别税基评估率的房产税在长期能更好地促进金融活动和实体经济的协调发展,对经济增长的促进作用更强,有利于实现"稳增长""防风险"和"促改革"的统一。     

规模经济、城市化和经济聚集

城市化和经济聚集是现代区域经济理论关注的核心问题。然而由于城市化现象所反映的规模收益递增因素与新古典经济的竞争性均衡不相容,因此,城市化问题很难在新古典经济学的框架内得到解释。这样,长期以来标准的经济分析很少关注经济聚集现象和城市的形成。直到20世纪70年代,迪克西特和斯蒂格利茨把垄断竞争问题重新引入到主流经济学后,垄断竞争模型才成为处理规模收益问题的有力工具,新经济地理也由之发展而来;与此同时,新兴古典经济学以超边际分析为工具深入分析了分工对城市形成和产业迁移的影响。

城市流通系统:研究现状与一个综合性框架

现代流通产业的发展演变过程是伴随着现代城市的产生与发展过程进行的,现代城市是现代流通产业的载体,而城市则因为流通产业的发展而发展、壮大.因而,流通问题与城市问题是密不可分的.目前城市流通问题的研究集中在商业地理学领域,而传统流通理论则游离于该领域之外,这种游离造成了该领域研究的一些问题.本文在比较全面地回顾和评述了国内外学者对城市流通问题研究现状的基础上提出了一个综合性的研究框架,以期为城市流通问题的研究提供新的视角.

The Effect of Environmental Corporate Social Responsibility on Environmental Performance and Business Competitiveness: The Mediation of Green Information Technology Capital

With the emergence of environmental sustainability and green business management, increasing demands have been made on businesses in the areas of environmental corporate social responsibility (ECSR). Furthermore, the influence of ECSR on green capital investment, environmental performance, and business competitiveness has also been the subject of attention from enterprises. However, in previous studies, the mediating role of green information technology (IT) capital in the relationship between ECSR, environmental performance, and business competitiveness, has not been investigated by researchers. In order to bridge this gap in the ECSR literature, this study aims to examine the influence of ECSR on green IT capital, and the consequent effect of green IT capital on environmental performance and business competitiveness. Data were collected from 358 companies from the top 1000 manufacturers in Taiwan. The results confirmed that ECSR has significant positive effects on green IT human capital, green IT structural capital, and green IT relational capital. Green IT structural capital and green IT relational capital have positive effects on environmental performance and business competitiveness, and environmental performance has a positive effect on business competitiveness. In addition, green IT structural capital and green IT relational capital have partial mediating effects on ECSR, environmental performance, and business competitiveness. The implications and suggestions for future research are discussed.
