The Application of Mathematical Programming Approaches to Estimating Container Port Production Efficiency

Container terminal production is both an important and complicated element in the contemporary global economy. This paper aims to evaluate the efficiency of the world’s most important container ports and terminals using the two alternative techniques of Data Envelopment Analysis (DEA) and the Free Disposal Hull (FDH) model. The results give an insight into the current efficiency ranking of the world’s major container ports and terminals. They also confirm expectations that the available mathematical programming methodologies lead to different results and that appropriate variable definition of input and output factors is a crucial element in meaningful applications of DEA and FDH. It is also concluded that the availability of panel data, rather than cross-sectional data would greatly improve the validity of the efficiency estimates derived from all the mathematical programming techniques applied.JEL Classification:C61, D24, E23, L23, L25, L92

A dynamic perspective: local interactions driving the spread of social networks

ABSTRACT

This study takes a micro standpoint to quantitatively verify the extent to which local interactions affect the expansion of dynamic social networks. By reviewing and synthesizing the theoretical literature in this article, we seek to establish a pragmatic analytical framework to capture the underlying functioning of local interactions. It then aims to produce findings on seven distinct marketing campaigns in which the real-world virtual communities offer intact time-series connections. In our considered cases, the firm-to-consumer interactivity plays a pivotal role in social media marketing while the customer-driven influence advances individual information transmission. The significant positive relationships demonstrate features of interactivity within subgroups including reciprocal edges and directed 3-cliques associated with the evolution of the virtual community by electronic word-of-mouth (WOM) of both firm-to-consumer and consumer-to-consumer interactions. More importantly, the attenuation of local interactions to a large extent leads to the cut-off point of the growth of the dynamic social network.

管理科学在中国:管理学科结构探索

管理科学是所有以管理活动作为研究对象的学科的统称。管理科学在20世纪70年代末被引入我国之后,解析其学科结构逐渐成为管理科学元研究的一个重要课题。对管理科学的数百门分支学科、边缘分支学科进行结构性梳理,按照具体研究对象的异同将它们归并为7个一级子系统;旨在发现其学科结构中的"缺失"环节,促进其整体上的均衡性发展和可持续发展。以科学技术管理学、技术管理学为例,阐释了管理科学的分支学科仍存在着深度分化发展的必要性和可能性。

我国货币政策区域效应的存在性及原因--基于最优货币区理论的分析

早在蒙代尔提出最优货币区理论之时,他就指出了最优货币区的范围可以大于国界,也可以在一国国界之内。本文把常用于国际经济领域的最优货币区理论运用于我国这样一个大国内部,指出我国并不满足最优货币区标准;利用VAR模型和IRF检验也证实我国货币政策存在显著的区域效应。进一步,本文从货币政策传导机制的角度分析得出信贷渠道和利率渠道是导致我国货币政策区域效应的主要原因。最后本文提出推进生产要素自由流动,缩小东中西区域经济差异,顺畅我国货币政策传导机制的建议。
