间断性服务业顾客忠诚维度及其影响因素

This research empirically studies customer loyalty in the intermittent service industry with samples from the catering business in Beijing. Results show that customer loyalty in the intermittent service industry is composed of three causally related dimensions, namely cognitive loyalty, affective loyalty, and behavioral loyalty. Factors influencing customer loyalty in the intermittent service industry are customer satisfaction, service quality, and customer perceived value (CPV), in descending order of significance. These factors vary in their function mechanisms and effects on different dimensions of customer loyalty. __________ Translated and revised from Shuliang jingji jishu jingji yanjiu 数量经济技术经济研究 (The Journal of Quantitative & Technical Economics), 2007, (3): 91–101     

并购式内创业中的人力资源整合水平和模式研究

When firms start intrapreneurship by merger or acquisition, the level and pattern of human resource integration becomes a critical issue. However, extant literature has paid scant attentions to this issue. Drawing on the previous researches on M&A intrapreneurship, the present article collected primary data of the level and pattern of human resource integration in M&A intrapreneurship by means of in-depth interviews and used content analysis method to structurally analyze the data. The results showed that enterprises engaging in M&A intrapreneurship generally choose a high or intermediate level of HR integration. Specifically, enterprises at high level of HR integration tend to absorb employees from the acquired directly or recruit afresh employees, while enterprises at intermediate level of HR integration are inclined to adopt an agent-type of integration pattern.

企业创新悖论与两栖组织模式——基于海尔空调产品开发团队案例的研究

While knowledge exploration and exploitation represent two distinct activities requiring corresponding organizational arrangements, new product development calls for a dynamic combination of the two. Based on a systematic review of the paradox between knowledge exploration and exploitation and various resolving strategies, this research extends the construct of organizational ambidexterity from dual structure to ambidextrous capabilities, and suggests a dialectical method for reconciling this paradox at lower organizational levels. Based on a case study on the development teams of air conditioner in Haier, we find that ambidexterity is a multi-level construct existing not only at the organization level but also at lower levels such as teams and individuals like model managers.

企业文化与企业绩效的关系研究——一致性和均衡性的观点

Building on the Competing Values Framework (CVF), we investigated the relationship between organizational culture and performance. The perspective of consistency and that of balance were applied to examine the relationship. We tested our hypotheses on a sample of 270 companies in China, which resulted in two major findings. First, the consistency between organizational culture and external environment was found positively associated with organizational performance. Consistency was operationalized as a match between an organization’s current culture and its preferred future culture. Second, balance of organizational culture was found positively correlate with organizational performance. A balanced culture was defined as one in which values of each of the CVF culture types are equally held.

中国企业渠道联盟关系影响因素研究

Channel alliance is regarded as the most advanced form of channel relationships. The extant literature mainly focuses on commitment, trust, communication and cooperation as influencing factors of channel alliance relationship. This paper empirically explores influencing factors of channel alliance relationship in Chinese enterprises, and their respective degrees of influence, particularly those of personal relationship and government administrative factors. Research hypotheses were tasted based on a survey of automobile vendors and dealers. Three most important influencing factors were identified “commitment and trust”, “communication and cooperation”, and “returns”. __________ Translated from Nankai Guanli Pinglun 南开管理评论 (Nankai Business Review), 2006, 6(1): 42–48     

论中国招商引资过程中政府决策的合理性

Based on consumer and manufacturer behaviors, this research describes local governments’ unique role in the process of “attracting foreign direct investment (FDI)”. Drawing from a sample of 28 provinces plus four cities throughout China from 1998 to 2004, we construct an econometric model in this paper to analyze the common factors that influenced the result of “attracting FDI”. The main finding of this paper is that in the process of “attracting FDI”, local governments play a decisive role, which puts consumer surplus, producer surplus and the other social welfare into a basket to construct its plan for “attracting FDI”. The common factors which influence the result of “attracting FDI” are local costs, the number of foreign-invested company, the market share of local companies, and the market share of foreign-invested companies.

Milk yields,physico‐chemical properties and composition of milk from indigenous Malawi goats and their Saanen half‐breds

A study to compare milk yield, some physico‐chemical properties and the chemical composition of milk from 23 indigenous Malawi goats and 10 Malawi local × Saanen crosses was carried out from January to March 2000. The results showed that the average milk yield from the crosses (102.0 ± 11.21 kg) was higher (P < 0.01) than that from the indigenous goats (37.1 ± 4.79 kg). However, the pH and specific gravity of both milk samples did not differ significantly from each other. The latter was attributed to the fat and total solids contents, which did not differ significantly in the two milk samples. Although the crude protein content was not significantly different, lactose and minerals, namely calcium, sodium, magnesium, potassium and chloride, were higher (P < 0.01) in milk from the crosses than in milk from the indigenous goat. The results have shown that the levels of nutrients in goat milk are high, and this is indicative of its potential to improve the diets of rural Malawians. Also, as smallholder farmers sell raw unheated milk to the processing plants, such milk should not be kept for> 33 h in the cool dry season and for not> 20 h in the hot dry season. Farmers can also adopt a charcoal cooler to save the milk for an even longer time than they can at room temperature. In this case, the raw milk can only be stored for not> 20 h in the cool dry season and not> 16 h in the hot dry season.     

Responsibility of the University in Employability: Development and validation of a measurement scale across five studies

This paper develops and validates, at a confirmatory level, a second‐order scale to measure Responsibility of the University in Employability (RUE). First, the literature on the components of RUE is explored and a formative conceptual model is proposed to underpin its measurement using extant research in the field of organisational responsibility and employability. At the empirical level, the second‐order RUE model considers the reputation of the university, the teaching staff, and the matching activities with employers as components of RUE. This model is based on five empirical studies. The first is a small‐sample study based on the opinions of experts (n = 5) and the rest are based on representative samples of university students (n = 816, n = 1,082, n = 1,088, and n = 1,203). A very good fit between model and data were revealed (CFI = 0.975; RMSEA = 0.039; standardised X² = 2.676). The results indicate that matching activities with employers and teaching staff generate more RUE than university reputation. Guidelines are offered for managing the responsibility of the university in employability.     

Examining the Effects of Moral Development Level,Self-Concept,and Self-Monitoring on Consumers’ Ethical Attitudes

This study investigates the possible effects of self-concept, self-monitoring, and moral development level on dimensions of consumers’ ethical attitudes. “Actively benefiting from illegal activities,” “actively benefiting from deceptive practices,” and “no harm/no foul 1–2” are defined by factor analysis as four dimensions of Turkish consumers’ ethical attitudes. Logistic regression analysis is applied to data collected from 516 Turkish households. Results indicate that self-monitoring and moral development level predicted consumer ethics in relation to “actively benefiting from questionable practices” and “no harm/no foul” dimensions. Actual self-concept is also a predictor variable in relation to “no harm/no foul” dimension. Age and gender make significant differences in consumers’ ethical attribute dimensions.
