不良贷款约束下的中国银行业全要素生产率增长研究

本文运用共同边界Malmquist-Luenberger生产率指数测度了2004—2009年中国27家商业银行在不良贷款约束下的全要素生产率增长及其成分,并对影响全要素生产率增长的宏观经济因素进行了实证分析。本文的主要结论有:在表示偏离共同边界的技术落差比率方面,国有商业银行呈"V"型,股份制商业银行较平稳,城市商业银行逐步上升;总体上,中国银行业的全要素生产率是进步的,纯技术进步是推动全要素生产率进步的主要动力,纯技术效率变化和规模效率变化进步都不明显,技术规模变化显示中国银行业趋向CRS边界;股份制商业银行的纯技术赶超最优,而潜在技术相对变动方面表现较弱;外资银行进入和固定资产投资增加对银行全要素生产率提高有推动作用。     

The shading and distancing of commerce: When internalization is not enough

A political economy of degradation and of sustainability should account not only for the full range of production costs but the sources of those costs. It should consider how the pursuit of wealth can, deliberately or not, lead to uncounted costs and unaccountable actors. This article explores the conditions of cost generation and externalization, especially those that are largely unintended and inadvertent. It shows how the pursuit of wealth, the expansion of markets, the mobility of capital, and the entanglements of production processes can lead to the unwitting generation and displacement of costs. It analyzes competitive business strategy and patterns of production and consumption for their contribution to such costs. Business strategy and state policy tend to create a never-ending search for frontiers, however simulated and however unecological they may be. The costs generated in those frontiers are a function of shading, that is, obscuring of costs, and distancing, the separation of production and consumption decisions, both of which impede ecological and social feedback and create cognitive, institutional, and ethical lags between initial benefits and eventual full costs. As distance increases along dimensions of geography, culture, bargaining power, or agency, negative feedback loops are severed, stakeholders expand while decision making contracts, environmental problems are displaced, and shading and cost externalization increase. The likelihood of sustainable resource use increases as distance is lowered, as institutions locate decision authority in those who receive negative ecological feedback and who have the capacity and incentives to act on that feedback, and as the burden of proof for economic interventions shifts to the interveners.     

National politics and bank default risk in the eurozone

We study the impact of national politics on default risk of eurozone banks as measured by the stock market-based Distance to Default. We find that national electoral cycles, the power of the government as well as the government’s party ideological alignment significantly affect the stability of banks in the eurozone member countries. Moreover, we show that the impact of national politics on bank default risk is more pronounced for large as well as weakly capitalized banks.     

Unbundling the differences between Psychic and Cultural Distance: An empirical examination of the existing measures

The diversity between the country-scores of Hofstede, Schwartz, GLOBE, Håkanson and Ambos and Dow and Karunaratna is the main focus of this study. To investigate the correlation between the country-scores of these CD (Cultural Distance), pPD (perceived Psychic Distance) and PDs (Psychic Distance stimuli) instruments we apply the Mantel test, a test predominantly used in anthropology and genetics, which can be particularly insightful when examining “distance” data. The matrix correlation findings provide evidence supporting the high diversity between these measures and their lack of consistent results for the same countries. Therefore, despite the similarity between the way of conceptualizing and operationalizing CD that Hofstede, Schwartz and GLOBE share, these CD measures do not report consistent findings. Consistently, the lack of correlation, between the PDs measure of Dow & Karunaratna and pPD of Håkanson & Ambos, indicates the diversity between PD stimuli measures and perceived PD measures. At the same time, while the two Psychic Distance (PD) measures indicate high correlation in some cases, overall they are highly diverse from the CD measures. We argue, therefore, that identical studies could reach significantly different conclusions by simply using different measures of CD,pPD&PDs which then denotes significant implications for the reliability of research findings. Additionally, we point out potential weaknesses of these measures when examining culturally proximate countries and multicultural nations.     

为何言路难开?领导拒谏构念维度与形成机理探究

员工谏言不仅具有建设性,而且具有挑战性和结果的不确定性,使得领导者可能纳谏也可能拒谏。然而,现有研究主要关注员工谏言与领导纳谏,却忽略了领导拒谏。本研究在回顾员工谏言及相关研究的基础上发现,领导者会对员工谏言进行建设性评估和威胁性评估,具有建设性和防御性两种行为目的。基于此,首先,从领导者的双元行为目的出发探讨了领导拒谏的概念与维度,依据发展视角、人际视角和防御视角将领导拒谏划分为:指导员工驱动的拒谏、维持关系驱动的拒谏、保证权威驱动的拒谏。其次,分析了领导拒谏的形成机理,从谏言内容、谏言员工和谏言行为三方面考察领导者对员工谏言的认知评估过程,详细讨论了组织距离如何通过领导注意间接影响领导拒谏,并探讨了权力距离在领导注意与领导拒谏之间所具有的调节作用。本研究有助于推动领导拒谏的理论构建,拓展认知评估理论的应用,而且能为组织管理实践给予一定的参考与借鉴。     

Mobile technology & resident attitude research

This research note highlights the novelty of integrating location-based services (LBS) available on Smart Phones and Tablets into traditional resident attitude survey methodologies such as door-to-door data collection. It specifically reviews how the LBS technology available on mobile devices can be used to systematically capture GPS coordinates of one's residence and integrate this captured spatial information into software such as ArcGIS and SPSS for further analysis. By having GPS coordinates associated with respondents' answers, researchers have an additional layer of information available for conducting a multitude of tests previously not possible with subjective categorical spatial data. Two research applications using the spatial location of residences are provided as examples of how LBS available on mobile devices can be integrated within resident attitude projects. The use of LBS technology can help researchers better understand how the distance residents live from major tourist attractions influences their attitudes towards tourism.

基于KMV模型的中国上市公司信用风险研究

本文利用GARCH模型估计股权价值波动率,用迭代程序估算资产价值及其波动率,以总资产的平均增长率代替资产价值预期增长率,建立了修正的KMV模型。文中对2006年沪深两市80家上市公司的信用风险进行评估检验,结果表明修正后的KMV模型不仅能够较好地分辨出ST公司和非ST公司信用风险的差异,而且能准确地把握上市公司信用质量的变化趋势,至少可提前一年识别上市公司信用质量的恶化。     

基于DEA的绿色经济增长核算:以中国地区工业为例

本文构建基于DEA的绿色经济增长核算模型,将考虑非期望产出的劳动生产率变化分解为技术效率变化、技术进步和资本深化。中国地区工业的经验分析表明,与发展水平无关且省际差异大的技术无效率普遍存在;各省工业增长的首要源泉是资本深化,其次是技术进步主导的全要素生产率进步;各省工业劳动生产率增长差异主要源于资本深化差异,其次是技术效率变化差异主导的全要素生产率进步差异;如不考虑非期望产出,会低估资本深化对经济增长的贡献,高估技术进步的贡献,而技术效率变化的贡献可能被高估、低估或无影响。     

重庆市制造业的绿色经济增长核算：2001—2010

基于生产前沿理论的绿色经济增长核算模型,不仅将技术无效率和环境代价纳入了分析框架,而且还与“物质平衡思路”一致;该模型将绿色经济增长的源泉分解为环境约束下的技术进步、技术效率变化和资本深化3大部分.对重庆市27个制造行业的经验分析结论表明:经济增长中普遍存在着技术无效率现象,但50％以上行业的技术效率都得到了改善或维持不变;资本深化是经济增长的主要源泉,而技术进步主导的全要素生产率变动在其中的贡献相对较小;技术进步是引致全要素生产率增长的主要原因.为充分发挥重庆市制造业可持续发展潜力,后续发展中必须转变经济发展方式,在环境约束下走技术进步和技术效率改善的绿色全要素生产率增长之路.
