我国城乡耐用消费品市场用户构成差异的研究——一个创新扩散的视角

创新扩散理论按照用户采用新产品的时间先后顺序将市场细分为创新者、早期采用者、早期大多数、晚期大多数和落后者五种类型。本文在扩散经典理论和中国市场特征的基础上,提出城镇市场和农村市场耐用消费品用户构成差异的假设。研究结果证实了全部假设:城镇的创新者比例显著高于农村,农村的早期采用者比例显著超过城镇,而各类型采用者的采用持续时间农村全面长于城镇。这些结论为更加深入地了解二元经济结构下中国市场的特征提供了有益启示。

Transferability and Naturalistic Generalization: New Generalizability Concepts for Social Science or Old Wine in New Bottles?

Interpretative qualitative social science has attempted to distinguish itself from quantitative social science by rejecting traditional or ‘received’ notions of generalization. Traditional concepts of scientific generalization it is claimed are based on a misguided objectivism as to the mechanisms operating in the social world, and particularly the ability of statements to capture such mechanisms in any abstract sense. Instead they propose new versions of the generalizability concept e.g. ‘transferability’, which relies on the context dependent judgement of ‘fit’ between two or more cases instances made by a researcher. This paper argues that the transferability concept, as outlined and argued by interpretativist methodologists, is thoroughly coextensive with notions of generalizability formalized for natural science and naturalistic social science by philosophers and methodologists of science. Therefore, it may be concluded that the interpretativist claim to a break with received scientific traditions is a premature one, at least with regard to the issue of generalization.     

On the Extendibility of Brands with Subordinate versus Basic Category Concepts

In this paper, we use a series of experimental studies to show that consumers’ response to the extension of a brand associated with a basic versus a sub-category depends on the closeness of the brand's parent and extension categories. When the two categories are close, consumers respond more favorably to the extension of a brand with a basic category concept, but the pattern reverses when the categories are far apart. However, a brand with a basic category concept can mitigate its disadvantage in a distant category by first launching an intervening line extension. Our results suggest that brands with sub-category concepts are not limited in their ability to extend, and can help retailers meet the twin objectives of leveraging the high growth of specialized categories and rationalizing their brand portfolio. They also suggest that managers should aim to extend brands with sub-category concepts into distant categories where the modifier in the brand concept is relevant rather than into close categories.     

Crowding,satiation, and saturation: The days of television series' lives

The performance of firms depends not just on the structure of the industries in which they compete but also on their relative positioning within those industries, in terms of operating within particular niches. We propose that demand for these niches depends endogenously on the historical ecology of the products offered: Niches become saturated—reduced in their ability to support products—as a large number of previous offerings allows the audience to satisfy its desire for products of a particular type. Analyzing the survival rates of television series aired in the United States from 1946 to 2003, we found that the survival rates of future entrants fell with the extensiveness of recent offerings in the niche, and that the negative association between crowding and survival also weakened with this saturation.

Categorizing risks in seven large projects—Which risks do the projects focus on?

In a hierarchy of project objectives, strategic objectives will often be principally different from the operational ones. Operational objectives concern the project outputs/results, and strategic objectives concern the project goal and purpose. In this study, risks are categorized as risks to operational, long‐term, or short‐term strategic objectives, and, by studying a dataset of some 1,450 risk elements that make up the risk registers of seven large projects, we examine how operational and strategic risks are distributed in the projects. The study strongly indicates that risks to a project's strategic objectives rarely occur in the project's risk registers, though project success and failure stories indicate their importance.

非利息收入对银行业绩效影响的实证研究——基于中国银行业2000—2010年面板数据分析

本文将非利息收入种类数和非利息收入占营业收入比作为非利息收入的两个衡量指标,并将其纳入非利息收入对银行绩效影响的模型中。基于我国14家股份制商业银行2000-2010年财务数据的实证研究发现,无论是非利息收入种类数,还是非利息收入占营业收入比,都与银行业绩效显著负相关。银行业绩效的提升更多的来自于银行规模的增大、股东权益资产的增加以及银行的上市。
