省域发电检修市场模式的优势

随着主辅分离政策的逐步实施,传统的检修模式必将发生重大变革,本文对如何建立省域检修市场提些建议和看法。传统检修市场模式的弊端目前,我国不少发电企业(特别是老企业)均有庞大的检修公司或维护人员。尽管部分企业将其纳入多经范畴,并进行了一些公司化的改革,但由于整个多经产业对主业依赖太多,加之传统观念和服务市场等方面的影响,使这种“自备服务”模式形成了管理粗放、专业太细、成本难控等弊端。主要表现在:1.检修的核心作业能力不强一是服务对象单一,没有及时跟踪服务非本企业的大机组,使自身的检修技术能力得不到及时更新和提高;…

Segmenting a business market for a professional service

This article uses benefit segmentation to analyze the structure of an industrial market for professional services— the market for CPA services among business firms. Data were collected from a random sample of U.S. business firms, stratified to include a broad cross section of the market for CPA services. Benefit segments were described by linking CPA selection criteria importance ratings with client firm characteristics such as business firm size. Examples of ways in which information about market structure can be used in marketing professional services are presented. The results provide evidence about the applicability of prior industrial marketing research and multilevel industrial market segmentation models to a professional services market.     

The fit between product market strategy and business model: implications for firm performance

We examine the fit between a firm's product market strategy and its business model. We develop a formal model in order to analyze the contingent effects of product market strategy and business model choices on firm performance. We investigate a unique, manually collected dataset, and find that novelty‐centered business models—coupled with product market strategies that emphasize differentiation, cost leadership, or early market entry—can enhance firm performance. Our data suggest that business model and product market strategy are complements, not substitutes. Copyright © 2007 John Wiley & Sons, Ltd.

Institutional maintenance work and power preservation in business exchanges: Insights from industrial supplier workshops

This paper aims to offer new theoretical and empirical insights into power dynamics in an industrial supplier workshop setting. Theoretically, it advances an institutional perspective on supplier workshops as an important venue in managing, preserving and instituting industrial market power. Based on a detailed ethnographic analysis of an industrial workshop setting, this article investigates the institutional maintenance work of Retail Co. in preserving the power dynamics of market dominance in business exchanges and market structures. Our findings revealed three previously unreported insights into the subtle, but nonetheless pervasive power from institutional maintenance work in an industrial workshop setting. First, the institutional workshop work comprised a cultural performance; constituting socialization practice through a performance game, the power of numbers in field comprehension and an award ceremony. Second, the institutional workshop work mobilized projective agency, stipulating, directing and appealing for the instituting of distinct market rules and collective identities. Finally, the institutional workshop work increases supplier docility and utility via the regulative technologies-of-the-self to enhance business planning, operations and market decision-making practice, without necessarily being seen to be disciplinarian.     

Beta distributed market shares in a spatial model with an application to the market for audit services

We show that if firms locate on a circle according to a uniform distribution, their market shares will be beta distributed. The result implies that concentration ratios will be skewed. We apply the result to the market for auditing services in the US and show the beta distribution outperforms other relevant distributions.     

Brand equity of defectors and never boughts in a business financial market

Buyer acquisition is important for any supplier looking to maintain or expand its customer base. This study uses a brand equity perspective to compare the future customer potential of those who used the brand in the past but stopped (defectors), with the potential of those who have never bought the brand. On the surface, both groups possess the same propensity to consider the brand for future purchase. However, the underlying reasons for these propensities differ. Defectors hold both positive and negative information about the former brand. In contrast, those who have never bought the brand possess largely neutral opinions. The results imply that managers should consider treating these two groups separately because they require different acquisition strategies.     

借鉴西方国家市场经济模式校正我国市场经济模式定位

市场经济是现代国家发展经济的主流经济形式.其对经济的自由调节、对资源和生产要素的配置作用已为经济学界所公认.虽然我国已步入市场经济时代,但由于计划经济向市场经济转变,受制度变迁形式和时滞因素的影响,形成完善的市场经济体制还需要一个过程.因此,学习借鉴西方国家市场经济模式有益成果,结合我国社会主义市场经济建设实际,是缩短我国市场化进程,最终形成有中国特色的市场经济模式的有效途径.     

Validating a model for forecasting the project termination phase using existing business cases

Studies on project failure and its subsequent termination phase are scarce; studies that use a quantitative approach are almost nonexistent. This is most likely because organizations usually do not collect data on project failures, are unable to share such data, or a combination of both. The contribution of this article is twofold: to (1) showcase a methodology to validate a model using actual business cases and (2) validate a project termination phase forecast model (PTPFM) using the methodology. The model is validated through four business cases, comparing the results from the model to the decisions made in reality.     

Reinventing a business model in industrial networks: Implications for customers' brand perceptions

Although researchers recognize the need for established market-centered business models that address and satisfy consumer's needs, little research has been done on the link between a customer's perception and a business model innovation (BMI). We addressed this research opportunity by conducting a case study encompassing 394 respondents to explore how a BMI affects customers' brand perceptions, distinguishing between their brand trust, brand loyalty, and brand equity. We conceptualize a BMI from an industrial network perspective and decompose the effect of different BMI dimensions: value offering innovation (VOI), value architecture innovation (VAI), and revenue model innovation (RMI). Our results show that a VOI has a positive impact on brand equity and a negative impact on brand loyalty. Further, a VAI has an inverted u-shaped relationship with brand trust, whereas an RMI has a positive impact on brand trust. In turn, brand trust fully mediates the relationships between an RMI and brand loyalty and an RMI and brand equity. Our insights contribute to BMI research from a customer-centric perspective. In particular, we extend our knowledge of BMIs by offering a more granular understanding of how different BMI dimensions affect a customer's brand perceptions. We contribute to industrial networks literature by offering rich and novel insights to purposefully manage an industrial network's BMI.     

The power of marketing within the firm: Its contribution to business performance and the effect of power asymmetry

While marketing continues to gain prominence as an orientation within the firm, concerns remain about the contributions of the marketing subunit. Given the current limited and conflicting evidence on the issue, this study responds to calls for research on the link between a powerful marketing subunit and business performance. The study draws on the critical contingencies perspective on power, which was specifically developed to study power distribution among organizational subunits. The key objectives of the study are (1) to determine whether a powerful marketing department is beneficial to business performance, (2) to reconcile conflicting evidence pertaining to the marketing function's contribution to performance beyond that of a market orientation, and (3) to investigate the effect on business performance of power asymmetry between marketing and other functions. Employing data from senior managers in medium and large manufacturing firms, the study shows that a powerful marketing function is associated with improved business performance above and beyond the contribution of a market orientation. Power asymmetry between marketing and finance/accounting and between marketing and production has a negative effect on business performance while a power asymmetry between marketing and R&D shows a positive effect on business performance. Finally, a differentiation strategy attenuates the negative performance outcomes of power asymmetry between marketing and production.
