Are supply-chain relationships more influenced by buyer-supplier relationships or the business environment of the country itself? Evidence from the ‘China-Australia’ trading relationship

In doing business with China, poor supply chain performance is reported as being caused by either poor relationships between firms in China or the business environment in which firms in China have to operate. This research paper explores the relative importance of these two factors for food supply chains from Australia to China. Results are based on surveys of 84 importers, wholesalers and retailers in China and 22 Australian exporters and wholesalers. They show that the country itself had a greater influence than firm to firm relationships. Firms exporting food to China should therefore keep supply chains as short as possible to minimize the uncertainties associated with the business environment.     

浅谈清单计价的编制方法、推广、普及及相关问题

随着工程建设领域的工程量清单计价规则在中国的推广和应用,这种国际上被广泛推崇的计价方法将会逐渐取代原有的定额计价方法。这是时代发展的必然结果。工程量清单计价的编制规则及方法也成为概预算工作者所应该掌握的必要技能,但是随之也带来了不适应的问题,需要广大的工程建设领域的概预算工作者尽快掌握其规律、熟悉其规则,以便迎接国际化大潮的冲击。

How a firm's position in a whole network affects innovation performance

A whole network consists of the relationships that exist among members of a population. However, prior studies treated the whole network as a metaphor, and consequently, existing empirical research is limited. As such, this paper investigates the effects of a whole network on firm innovation performance among firms engaged in the Korean semiconductor industry using three variables, namely main component, eigenvector centrality, and closeness centrality. The effects are then analysed using two-step generalised method of moments estimates. The results show a firm is included among the main component in a whole network, and the more centralised it is in terms of connectivity and distance, the more advantageous it is for firm innovation. The significance of this paper is two-fold; First, unlike previous studies that use variables reflecting collective characteristics, this study uses variables reflecting the characteristics of individual firms in a whole network. Second, it is a rare empirical study of a whole network.     

建设单位在EPC项目中采用全过程工程咨询模式的管理要点

我国社会主义市场经济以及科学技术的不断进步发展,推动了各建设企业的稳步前进。在当前新发展格局下,各种先进的科学技术被广泛应用于各行各业的建设发展过程中,对于建筑工程的发展来说也不例外。由于传统的管理模式,随着时代发展变化已不适用于企业的管理,因此,企业要重视在EPC项目中采用全过程工程咨询模式的管理方式。     

An examination of the congruence and incongruence between employee actual and customer perceived emotional labor

This study examines the effects of the congruence and incongruence between employee actual and customer perceived emotional labor on customer trust. Based on data collected from 510 service employee and customer dyads in restaurants, the results of response surface modeling indicate that customer trust is higher when employee deep acting and customer perceived deep acting are both high rather than both low. Customer trust is also higher when customer perceived deep acting is higher than employee actual deep acting rather than vice versa. The effects are different in surface acting: as employee surface acting and customer perceived surface acting increase, customer trust initially decreases, then increases, exhibiting a U‐shaped effect. Implications for both theory and practice are discussed.

Technical and environmental efficiencies and best management practices in agriculture

An Input Distance Function (IDF) is estimated to empirically evaluate and analyse the technical and environmental efficiencies of 210 farms located in the Chaudière watershed (Quebec), where water quality problems are particularly acute because of the production of undesirable outputs that are jointly produced with agricultural products. The true IDF is approximated by a flexible translog functional form estimated using a full information maximum likelihood method. Technical and environmental efficiencies are disaggregated across farms and account for spatial variations. Our results show that there is a significant correlation between the two efficiencies. The IDF is used to compute the cumulative Malmquist productivity index and the Fisher index. The two indices are used to measure changes in technology, profitability, efficiency and productivity in response to the adoption of two selected Best Management Practices (BMPs) whose objective is to reduce water pollution. We found significant differences across BMPs regarding the direction and the magnitude of their effect.
