The relationship between business diversification and productivity: considering the impact of process innovation at different corporate life cycles

This paper investigates the link between a firm's process innovation (PI) and its segment productivity at different life cycles. The results show that business diversification is negatively associated with a firm's productivity, and further reveal that a firm's PI moderates the above relationship. In addition, the corporate life cycle literature builds blocks for this study to explain that the involvement of administrative costs varies across life cycles when diversified firms get mature and bigger. Our empirical evidence indicates that the potential costs of a complex organisational structure contingent on business diversification at a firm's mature life cycle could be alleviated by the conduct of process innovation. As process innovation at different life cycles may alter managerial incentive that leads to different firm performance, the managerial implication is that diversified firms should appropriately engage in process innovation to prevent unfavourable liability from the development of their businesses.     

红砂岩地区基坑开挖对周边建筑物的影响

本文通过对衢州地区的一个深基坑工程周边的学校食堂、宿舍的建筑物沉降的监测和分析,探讨了红砂岩基坑开挖对周边建筑物产生的影响。监测结果表明,基坑开挖会引起周边建筑物不同程度的沉降变形,且主要发生在基坑开挖前的打桩阶段和基坑开挖阶段。两栋建筑物的沉降累计值基本已超过20mm,且最大的沉降量已接近40mm,较大程度超过房屋沉降监测警戒值,说明开挖的施工方案有待于进一步优化,此结论对于红砂岩地区基坑工程施工具有重要的工程意义。     

Does higher government debt link to higher social expenditure? New method,new evidence

Scholars believe that higher social expenditures are usually linked with higher government debts, whereas higher debts reduce social expenditures. However, it is reasonable to speculate that higher government debt may contribute to higher social spending, while fiscal deficits occur during a recession, which commonly creates greater demand for social expenditure. For a deeper investigation, this paper revisits the dynamic relationship between social spending and public debts in the time-frequency domain, using the novel wavelet-coherency analysis as well as the phase-difference technique to derive the co-moved and causal relationships between social spending and public debts in 13 OECD countries. The evidence identifies a dynamic relationship between variables. While higher social expenditures increase government debts, the shocks from government debts to social expenditures are conversely uncertain. We discover that higher government debt does reduce social expenditures, but it may be linked to higher social spending. The robustness of partial coherency and phase-difference discovers the role of a political party in the decision over social welfare programmes in the sample countries.     

社会主义与统一多民族国家的国家建设(1947-1965)

在民族区域自治制度的奠基过程中,通过社会主义宗旨所要求的贯彻群众路线、培养少数民族干部,成功促进了中央政府和各族人民群众的直接沟通;通过让各族人民群众翻身当家做主、改善民生福祉等社会主义性质的政治举措,形塑起各族人民群众对党和国家发自内心的认同;通过民族平等之制度前提、社会主义经济制度等制度性组织模式,以及相关具体实践途径,实现了中国各族人民大团结;在社会主义国家单一制、人民共和、中国共产党领导的制度基础之上,民族区域自治成功地将国家内部的不同民族凝聚成为具备有机整体结构的"中国人民",呈现为一种促进沟通、赢得认同、实现团结、巩固统一的统一多民族国家的国家建设过程。因此,民族区域自治成功实现清末以来统一多民族国家之国家建设质的飞跃的制度要义,恰在于社会主义这一国家根本制度。     

An Application of the Dynamic Network DEA Model: The Case of Banks in Taiwan

ABSTRACT

In this study, we apply the dynamic network slack-based measure data envelopment analysis model (DNSBM) to measure the efficiency of Taiwanese banks during the period 2005–11. Using the network structure, we define intellectual capital creation capability as one of the production stages. In order to capture the dynamics of the transformation process, the nonperforming loans and loan loss reserves are defined as carryover items. This study offers sufficient information for managers to understand not only the overall performance of their banks but also the efficiency of each production stage and the dynamic changes of the overall and divisional efficiencies.     

城市地铁系统发展规模与建设时机研究

利用全世界各地地铁系统发展相对完善的城市特征数据进行关联分析,论证城市地铁系统合理建设规模;利用国内已开通运营地铁城市特征数据构建规格化分析指标,判断地铁系统适宜的建设时机.研究结果表明:城市地铁系统发展规模与城市人口规模呈现正相关关系,但人均拥有地铁里程与线网客流强度呈现负相关关系;地铁系统建设时机则与市区常住人口数、人均GDP、一般公共预算收入、建成区人口密度等高度相关.     

强制减排和碳偏好影响下的制造商产能决策

为了研究在政府给定碳排放总量的约束下,面临随机需求的制造商的产能决策问题,在改进报童模型的基础上,比较了碳排放总量约束前后的制造商最优产量和单位产品减排量的变化,发现了排放总量约束使得最优产量减少。然后,在市场减排努力函数拉动需求的前提下,给出了制造商的最优产量和单位产品减排量之间的关系式,并且证明了减排努力函数可以是任意线性函数或者非线性的凹函数。最后通过算例分析印证了结论。

The Role of Product Originality,Usefulness and Motivated Consumer Innovativeness in New Product Adoption Intentions

Prior research has posited that product attributes are primary drivers of success that a firm must consider to develop a competitive advantage. Two product attributes, originality and usefulness, have been identified in the literature as significant dimensions of new product success. Customer demands differ, and more purchase intentions toward a new product depend on how consumers connect the product attributes to their own individual characteristics. Studying motivated consumer innovativeness as a personality trait may improve our understanding of the motivations for adopting innovations; however, questions remain regarding whether the effects of originality and usefulness on consumers' intentions to adopt are different when levels of these attributes are matching or dissimilar and what the relationship is between these effects and motivated consumer innovativeness. This study seeks to empirically investigate these effects and their relations by collecting data from 560 potential consumers in China. This paper uses hierarchical regression analysis to test hypotheses in four product domains as representative of higher or lower levels of usefulness and originality. The research shows that new product originality affects consumers' intentions to adopt new products only if it matches the level of new product usefulness. The results also reveal that motivated consumer innovativeness has a positive moderating role on the relationship between new product originality and consumers' new product adoption intentions when both attributes are at a lower level. The theoretical and practical implications for new product development and marketing communications are discussed.     

The effect of host country Internet infrastructure on foreign expansion of Korean MNCs

This study examines the effect of host country Internet infrastructure on a multinational corporation (MNC) foreign expansion. Using Heckman’s selection model on a sample of 2589 subsidiaries of 487 Korean MNCs between 1990 and 2011, we find that host country Internet infrastructure is important in MNC expansion decisions. In addition, we find that a well-developed Internet infrastructure within a host country leads to more investments from MNCs producing consumer over industrial goods and is more attractive to domestic market followers than market leaders. We find that the host country’s Internet infrastructure is important for an MNC foreign expansion decision, suggesting that efficient communication within an MNC is critical in coordinating globalized MNC subsidiary operations.
