Intra-industry diversification effects under firm-specific contingencies on the demand side

How do firm-specific, demand-related factors influence the relationship between intra-industry diversification (IID) and performance? Recent findings regarding the performance effects of IID depict a complex picture with curvilinear relationships and several contingencies. However, firm-specific contingencies on the demand side have remained unexplored. We analyze how IID relates to firm performance (market share) in the German automotive industry using panel data between 1999 and 2008. We specifically focus on a firm's high-quality brand image as a demand-side contingency. We find support for our hypotheses of complex curvilinear relationships as well as for moderating effects of brand quality. Our results have significant theoretical implications for the IID literature.     

市场全球化下的战略性自然资源国家治理

中国在原材料出口限制措施案和稀土等产品出口案中的相继败诉,表明中国在战略性自然资源治理方面离市场经济的要求仍有相当差距.符合世贸组织规则的中国战略性自然资源良好治理机制的构建,必须以承认这一差距为思想动力,深入理解市场规律,辨证认识国家自然资源永久主权同世贸组织规则之间的关系与衔接,通过提高体现战略性自然资源稀缺价值的资源税费、制定和执行旨在保护环境的严格而科学的环保制度、建立战略性自然资源类原材料产品储备制度和跟踪制度的路径而完成.     

The triggers of local and distant search: Relative magnitude and persistence in explaining acquisition relatedness

Research on problemistic search has assumed negative attainment discrepancy to be the trigger of both local and distant search. Extending this research, we present and compare two additional triggers: (1) relative attainment discrepancy, which reflects how much a firm's attainment discrepancy deviates from its past negative attainment discrepancies; and (2) persistent attainment discrepancy, which reflects how often the firm experiences below-aspirations performance. Our triggers for distant search model a behavioral explanation for the timing and relatedness of acquisitions. We find support for baseline arguments of problemistic search whereby firms increase both industry- and skill-related acquisitions when they perform below aspirations. When they persistently perform below aspirations, however, this likelihood is reduced and firms engage in acquisitions that are more unrelated, thereby providing support for the notion of expanding search boundaries from local to distant search. Of the two triggers of distant search proposed, relative attainment discrepancy does not induce firms to expand search boundaries. Our results indicate that persistent attainment discrepancy is a key construct to consider when studying the expansion of search boundaries.     

Validation of the Career‐Related Parent Support Scale Among Chinese High School Students

The Career‐Related Parent Support Scale (CRPSS; Turner, Alliman‐Brissett, Lapan, Udipi, & Ergun, 2003 ) was translated and modified to form the 24‐item Chinese version of the scale. As in the case of the original CRPSS, the Chinese version includes 4 subscales (Instrumental Assistance, Emotional Support, Verbal Encouragement, and Career‐Related Modeling). The Chinese version of the CRPSS was validated in this study with a sample of Hong Kong high school students (N= 677). Reliability analyses showed that the total scale and subscales were internally consistent. The results of the exploratory factor analysis and confirmatory factor analysis suggested that the Chinese version of the CRPSS provided adequate indicators of Chinese adolescents’ perceptions of parent support for their career aspirations.     

肿瘤科PICC常见并发症及其处理措施探讨

目的探讨PICC导管在恶性肿瘤化疗患者中的各种常见并发症及其处理措施。方法对300例肿瘤患者进行置管给药并观察置管的临床效果,及其引发的各种并发症。结果发生PICC相关性并发症38例(12.67%),行Logistic回归分析。结论影响留置PICC导管并发症的因素复杂,管理好老年患者、加强培训提高置管水平、实施PICC健康教育、尽量缩短留置时间可以减少PICC导管相关性感染发生,也能避免其他各种常见并发症。

关联方增信与资产证券化信用风险溢价——基于底层资产风险的统计分析

本文着眼于企业资产支持证券(ABS)市场的信用风险溢价,探讨关联方增信的效果。研究表明,采用关联方增信的ABS风险溢价较高;当同一主体先前发行的ABS评级上调时,新发行ABS的风险溢价会因为采用关联方增信而升高。本文进一步探究了产生上述现象的原因,一方面,关联方增信使得集团内部风险集聚;另一方面,企业的道德风险使得原ABS的评级上调成为反映新ABS底层资产质量变差的负面信号,从而影响投资者的定价判断。本研究揭示了关联方增信可能存在的道德风险问题。通过分析ABS丰富的底层资产统计特征,本文发现集团风险集聚导致ABS的底层资产质量下降,进而提高了企业的融资成本。本文建议监管机构可以通过适当限制关联方增信或加强监管的方式保障我国企业资产证券化市场的健康持续发展。

中国企业集团内交易与转移定价的规制

由于"企业性"和"市场性"特征,企业集团可能因其内部关联交易与转移定价而实施单个企业所无法运用的市场行为以谋求不当利益。因此,对企业集团(尤其是跨国公司)内不公平的关联交易与转移定价进行规制具有重要意义。本文简述环境变革对企业内交易与转移定价的影响,剖析企业集团内关联交易与转移定价引发的不当市场行为,如操纵利润、交叉补贴、逃废债务、垄断性并购等,并着重从税法、会计制度、反垄断法、公司法等方面提出对中国企业集团不当的市场行为进行规制,尤其是对企业集团内不公平的关联交易与转移定价进行系统规制的政策建议。
