我国中小企业融资效率综合评价和实证分析

中小企业在我国的国民经济和社会发展中发挥着重要作用,然而,中小企业在发展过程中面临很多困难和难题,其中以融资难最为突出。因企业的融资方式决定着企业的融资结构和融资效率,而融资效率又直接影响着企业的融资目的是否有效达到。因此,在我国现实背景下研究中小企业融资效率问题具有重要现实意义。文章在构建企业融资效率的数学评价模型时运用模糊综合评价方法。首先,对中小企业的五种融资模式的融资效率进行模糊综合评价,得出五种融资模式的融资效率,进而对我国中小企业的融资效率分析。其次,选取深圳中小企业板上市的28家中小企业作为研究样本来实证分析,比较权益和债券两种融资模式的融资效率。最后,由分析结果得出结论并提出相应的建议。     

The role of organizational control in outsourcing practices: An empirical study

Recent case study research has examined the role of organization control as a critical component of outsourcing performance (Kang et al. 2012a. Journal of Business Research 65, 1195–1201). In contrast to case study methodology, this paper aims to empirically examine the relationships among outsourcing strategies and organizational control in the Chinese context and refine the theoretical and managerial implications of the current research model. Based on data collected from 158 firms operating in China, this paper examines the impact of two types of outsourcing strategies on different organizational control measures. Our findings suggest that for efficiency-seeking outsourcing, output control and process control are appropriate in creating successful outsourcing practices. As for innovation-seeking outsourcing, social control and process control are the most effective options. Theoretical and managerial implications for strategic outsourcing are also discussed.     

高校教师教学绩效评价的影响因素分析——基于学生评教的实证研究

评价高校教师教学是政府、高校、教师、学生、家长和社会共同关注的话题之一,也是高教研究领域开展最为广泛的研究之一.国内外相关的研究很多,但是很多问题却尚未有定论.高校教师教学评价之所以难度大,很大程度上的原因是由于教师教学评价领域中涉及到多种主体及评价对象本身价值的多元性.本文通过调研和实证分析,以上海交通大学学生评教为实证案例,研究了27种可能影响教师教学绩效评价的因素,并进行了总结和分析,提出了改进学生评教工作的建议.     

A critical evaluation of alternative methods and paradigms for conducting mediation analysis in operations management research

Mediation as a theory testing approach has witnessed considerable adoption among Operations Management (OM) researchers. Although mediation-testing methods have evolved tremendously in the past decade, their dissemination in the OM field has not seen parallel growth. These advanced techniques facilitate the testing of existing and complex hypotheses in a more precise manner. With the intent of critically evaluating existing and alternative methods for conducting mediation analysis needed to support sophisticated empirical research, this paper first reviews OM studies that tested for mediation in the past eleven years (2002–2012) from top-tier OM journals. Four commonly used mediation approaches were identified. Based on principles of good theory building, type of mediation model, and properties of empirical data, we evaluate the existing methodologies and make recommendations on how to improve the rigor of OM mediation testing. Using published OM studies in top journals as examples, we then illustrate the relevance and advantages of these recommendations, as well as their ease of use. Furthermore, we empirically show that more robust and insightful results can be achieved by adopting these techniques, which in turn have the promise of leading to better theory building and testing in the field of operations management.

Outsourcing of Information Systems Functions in Small and Medium Sized Enterprises: A Test of a Multi-Theoretical Model

In this paper determinants of information systems (IS) outsourcing are deduced from transaction cost economic theory, resource-based theory and power theory. They are summarized in a theoretical framework which is tested using a sample of small and medium sized enterprises (SMEs) in Germany. The results show that internal performance and know-how deficits vis-à-vis external service providers are key determinants that explain why different IS functions are outsourced to varying degrees in SMEs. Moreover, the determinants of IS functions were found to partially differ between IS functions. Revised reprint of an article from WIRTSCHAFTSINFORMATIK 43(4)2001:339–350.

外资银行进入对我国银行业效率影响的实证分析——以四大国有商业银行为例

2006年底我国银行业向外资全面开放,外资银行开始与我国银行在各个领域展开全面的竞争。因此,研究外资银行进入对国内银行效率的影响,将有助于国内银行更好地采取应对之策。本文试图就外资银行进入对我国银行业效率的影响做实证分析,从盈利能力,经营管理水平,抗风险能力,资本结构等方面分别进行论证,进而对我国银行业的进一步发展提出相应的政策建议。     

An empirical investigation of organizational memetic variation

The potential of a theory based on organizational memes in coevolution with the environment has been postulated, but remains empirically under-developed. This study explores whether understanding organizational memetic variation is empirically possible and, if so, whether it might, with further development, provide managers with early indications of a misalignment between organizational action (operationalized as memetic variation) and strategic intent—the amount of memetic variation needed to stay aligned with the competitive environment. A method for empirically identifying knowledge-based memes in everyday practice is developed. It stems from modern advances in genetics allowing micro-level changes in genes to be linked to macro-environmental dynamics. Using the concept that memetic variation is caused by everyday, uncontrollable uncertainties of interpretation, memetic variation is reduced to seven categorical types. A highly exploratory quasi-experimental design allows a preliminary comparison of a would-be innovative ‘Portfolio Management Committee’ with self-organizing Internet chat-room settings that are representational of open-source innovation. Results are consistent with predictions showing that higher levels of variation are seen in the latter, despite the former’s strategic intent of innovating to stay aligned with a dynamic environment. Further work is needed, however, to test reliability and validity.      

中国价格贸易条件变动趋势与出口商品结构——基于1981-2007年的时序数据的研究

利用回归方程对1981-2007年中国贸易条件变动趋势进行测算,研究发现:中国贸易条件以每年4.6%的速度下降,其中工业制成品贸易条件下降是主要动因。在此基础上,利用协整模型对价格贸易条件与工业制成品出口比例的相关关系进行实证检验:长期来看,价格贸易条件与工业制成品出口比例之间存在着稳定的协整关系,并且工业制成品出口比例上升是造成中国价格贸易条件恶化的格兰杰原因。
