基于风险收益关系和风险倾向的战略风险行为研究

战略风险中的行为因素对企业竞争优势和整体绩效具有显著影响,其核心问题是风险收益的对称性以及风险倾向与组织绩效的关系。文章从Bowman的风险收益悖论、风险承担态度和战略参考点的视角对战略风险行为进行了系统考察,结合战略风险行为的SCP分析范式,探讨了组织风险倾向和竞争优势的关系,分析了不同风险态度下的组织业绩表现。     

基于BRSCP框架的中国数字电视产业分析

中国的有线电视产业正在从模拟电视向数字电视过渡。为了分析有线数字电视这一新兴产业,本文提出了BRSCP的产业分析框架,然后基于该框架分析了中国有线数字电视产业的供需特点,规制、产业结构、企业行为和产业绩效,研究发现中国的数字电视产业面临三大问题：第一,技术、商业模式和市场需求之间的矛盾;第二,数字电视网络运营商的区域垄断;第三,规制滞后于网络融合。最后提出政策性建议。

产业组织理论的哈佛学派

产业组织理论是现代经济学的重要组成部分,是一门用以分析、研究市场经济条件下涉及经济运行问题的新兴的应用经济理论。哈佛学派作为产业组织理论发展史中最早形成的流派,其产生及发展都对产业组织研究产生了重要影响。本文拟对哈佛学派的学派形成、理论体系等问题的历史研究做一综述。     

基于SCP模型的我国旅行社业的经营测度

文章基于SCP模型,运用结构方程方法从市场结构、企业行为和企业绩效3大模块构建了我国旅行社业SCP分析模型,并对我国旅行社业的市场结构、企业行为和企业绩效的状况及它们之间的关系进行了定量测度.研究得出:目前我国旅行社业整体绩效很低,净资产利润率有趋近于零的趋势.从3大模块来看,旅行社企业行为是旅行社企业绩效的主要影响因素,而旅行社企业行为受旅行社业市场结构的影响也很大.从3大模块的具体影响因素来看,产品差异性和市场集中度是对市场结构影响最关键的因素,价格恶性竞争的程度是对旅行社业行为影响最大的因素.     

Constructing Business-to-Business Marketing Models that Overcome the Limitations in Variable-Based and Case-Based Research Paradigms

ABSTRACT

Purpose: This article describes the principal limitations frequently observable in variable-based and case-based research in business-to-business (B-to-B) marketing.

Focus: The limitations relate to B-to-B theory construction, data collection, and data analysis and interpretation. The principal limitations in variable-based research include the reliance on regression (net effects) models in theory construction and the pervasive failure to test resulting empirical regression models for predictive validity. The principal limitations of case-based research are the frequent absence of rigorous theory formulation either pre- or postdata collection and failures to test propositions for predictive validity.

Recommendations: The article directs attention to iconic studies that break free in part from these and additional limitations. The article offers useful steps on how to break free completely from the principal limitations.

Managerial implications: B-to-B executives should insist that researchers include asymmetric algorithm models in reports that include symmetric (regression analysis) and analysis of variance findings.     

ALTERNATIVE ESTIMATING AND TESTING EMPIRICAL STRATEGIES FOR FRACTIONAL REGRESSION MODELS

Abstract In many economic settings, the variable of interest is often a fraction or a proportion, being defined only on the unit interval. The bounded nature of such variables and, in some cases, the possibility of nontrivial probability mass accumulating at one or both boundaries raise some interesting estimation and inference issues. In this paper we (i) provide a comprehensive survey of the main alternative models and estimation methods suitable to deal with fractional response variables, (ii) propose a full testing methodology to assess the validity of the assumptions required by each alternative estimator and (iii) examine the finite‐sample properties of most of the estimators and tests discussed through an extensive Monte Carlo study. An application concerning corporate capital structure choices is also provided.     

Objective Bayes Factors for Inequality Constrained Hypotheses

This paper will present a Bayes factor for the comparison of an inequality constrained hypothesis with its complement or an unconstrained hypothesis. Equivalent sets of hypotheses form the basis for the quantification of the complexity of an inequality constrained hypothesis. It will be shown that the prior distribution can be chosen such that one of the terms in the Bayes factor is the quantification of the complexity of the hypothesis of interest. The other term in the Bayes factor represents a measure of the fit of the hypothesis. Using a vague prior distribution this fit value is essentially determined by the data. The result is an objective Bayes factor.     

中国商业银行市场结构与产品差异化关系分析

我国商业银行业市场结构寡占程度较高,产品差异化不显著,顾客在选择银行产品时首先考虑的是得到服务的便利程度,网点数量的多寡在很大程度上就决定了客户的选择。中小型银行无法大规模铺设网点,只能通过价格竞争争取市场份额,市场上出现＂伯川德悖论＂。但是一旦在市场上引入了产品差异化,只要差异化的效率足够高,就能避免恶性价格竞争,并通过差异化获取更大的市场份额,使银行业市场结构发生变动。因此政府可以通过鼓励中小型银行推行产品差异化战略对银行业的市场结构做出调整。     

农村集体经济:历程、现实矛盾与路径选择——基于安徽省973个行政村调查资料的分析

发展农村集体经济是新时代中国特色社会主义的重大课题。文章以安徽省973个样本村的调研资料为基础,梳理了农村集体经济发展的脉络,剖析出农村集体经济发展过程中存在的现实矛盾,并基于SCP分析范式,探讨出农村集体经济的发展路径:重新赋予农村集体经济组织的组织和管理职能,引入村两委、村民代表大会和上级政府,完善对农村集体经济组织的有效制约和监督,实现农村集体经济生产制度、交易制度、监督制度、收入分配制度的创新,进而实现盘活农村集体经济的目标。
