DEA评价模型应用的几点探讨

为更好地应用ＤＥＡ评价模型，本文讨论了ＤＥＡ模型中定性指标的模糊处理及权重分布的随机处理，运用主成分分析法对ＤＥＡ模型指标体系进行处理，并对ＤＥＡ评价结果进行了排队分析．

On asymptotic distribution of the test statistic for the mean of the non-isotropic principal component

In this paper, the authors derived the large sample distribution of the t statistic based upon the observations on the first principal component instead of the original variables. It is shown that the above statistic is distributed asymptotically as Student's t distribution.

基于主成分分析法的自主创新能力综合评价——以湖南省为例

自主创新是中国实现现代化的关键。通过利用主成分分析法对湖南自主创新能力进行综合评价,结果显示湖南自主创新能力呈现出逐步提高的趋势,但和较发达的省份相比,仍存在较大差距。因此,湖南省应进一步增加研发和教育投入,加强人才的引进和培养,通过自主创新提升湖南的发展力和竞争力。     

单一正犯体制的反思与检讨

各国刑法对共同犯罪的规定有正犯·共犯区分体制与单一正犯体制。文章以我国学者关注相对较少且存在不少误解的单一正犯体制为题，在对单一正犯体制的理论基础进行分析的基础上，就单一正犯体制的理论基础进行了反思与检讨，并进一步对其适用中的困境进行深入的反思，以期为正确理解单一正犯体制提供些许助益。     

河北省普通高等教育发展的动态评价

在综合评价的方法中,主成分分析能浓缩信息,使指标降维,简化指标的结构,使分析问题简单、直观、有效,许多动态评价问题,都可采用主成分分析来进行评价。针对区域普通高等教育发展的特点,建立综合评价指标体系,利用主成分分析评价了2000年以来河北省普通高等教育发展的情况,分析了影响因子情况,可以为河北省普通高等教育发展政策提供依据。     

Supply Chain Strategies and International Tax Arbitrage

What motivates the geographic footprint of the supply chains that multinational firms (MNFs) deploy? Traditional research in the operations and supply chain management literature tends to recommend locations primarily based on differentials in production costs and the ramifications of physical distance ignoring the role of taxation. MNFs that strategically position parts of their supply chains in low‐tax locations can allocate the profits across the divisions to improve post‐tax profits. For the profit allocation to be defensible to tax authorities, the divisional operations must possess real decision authority and bear meaningful risks. Generally speaking, the greater the transfer of risk and control, the larger the allowable allocation of profit. These transfers may also create inefficiencies due to misalignment of business goals and attitudes toward risk. We model these trade‐offs in the context of placing in a low‐tax region a subsidiary that oversees product distribution (as a limited risk distributor commissionnaire, limited risk distributor, or fully fledged distributor). Our analysis demonstrates that the MNF's preferences regarding the operating structures are not necessarily an obvious ordering based on the amount of risk and decision authority transferred to the division in the low‐tax jurisdiction. We derive and analyze threshold values of the performance parameters that describe the main trade‐offs involved in selecting an operating structure. We find some of the optimal decisions to exhibit interesting non‐monotone behavior. For instance, profits can increase when the tax rate in the low‐tax jurisdiction increases. Numerical analysis shows that the Limited‐Risk Distributor structure is rarely optimal and quantifies when each alternative dominates it.     

房地产上市公司财务预警实证研究

房地产业已成为我国重要的支柱产业,因此,建立房地产上市公司财务预警方法对政府、投资商、中介公司和广大消费者都具有重要意义。以主成分分析和逻辑回归分析为基础建立分析模型,并用该模型对2002~2005年沪、深两市45家房地产业上市公司进行实证分析,发现模型对房地产上市公司前两年和前四年的财务预警有较高的可信度。
