How professional service firms compete in the market: an exploratory study

Abstract

This study investigates how professional service firms (PSFs) compete in the market. Drawing on strategic marketing literature, a managerial rather than customer perspective is adopted. The study investigates the competitive positions sought by professional service providers and the specific marketing activities actually undertaken to achieve these positions. Thirty-seven depth interviews with senior management from a range of PSFs indicate that firms seek to differentiate themselves by developing long-term relationships, providing better service quality and greater value, and developing brands with strong reputations. Organisations typically seek such interrelated competitive positions simultaneously. A list of marketing activities used by the PSFs to achieve these competitive positions offers practical insights into the specific activities needed to achieve the various competitive positions sought.     

Code and conduct in French cuisine: Impact of code changes on external evaluations

We study the effects of organizational code‐preserving and code‐violating changes on external evaluations by third parties—an essential but under‐studied strategic outcome. We define code‐preserving changes as a variation in the firm's product range that preserves the social code within which the firm positions its offering. By contrast, a code‐violating change corresponds to a variation in the product range that breaks with past codes and embraces another social code. Our analyses of French haute cuisine restaurants show that code‐preserving changes and code‐violating changes have positive effects on external evaluations. Both effects decline with prior evaluations received by the organization, but only the effect of code‐violating changes is reduced with age. Moreover, external evaluations improve when restaurants undertake more code‐preserving changes than their direct competitors but decline when they make more code‐violating changes than competitors. These results enable us to derive implications for research on strategic change, strategic groups, and strategic social positioning. Copyright © 2007 John Wiley & Sons, Ltd.

我国民营银行的市场定位及经营模式研究

由民间资本发起设立民营银行既是经济转型发展的要求,也是民间资本自身多元化投资的需要。民营银行既有优势和机遇,也面临巨大的劣势和威胁。民营银行进入竞争已经十分激烈的银行业市场,必须寻找到一个明确而又适合自己的市场定位,才能站稳脚跟寻求发展。民营银行的市场定位应从两个维度考虑:所在地区和中小微企业,与大型银行错位竞争并提供更专业化的服务,有针对性地布局网点,借鉴"直销银行"的模式,基于中小微企业金融需求创新产品,与其他金融机构广泛合作,制定严格的风险控制制度。     

底子薄、空间窄、生态弱地区发展中政府—市场角色定位研究——以三峡重庆库区为例

三峡重庆库区在经济社会发展中受到经济底子薄弱、发展空间狭窄和生态环境脆弱三重叠加约束,这是新时代推进西部大开发中必须攻克的难题。破解三重约束叠加难题必须正确定位政府和市场在发展中的角色和地位,具体而言,在当前三峡重庆库区追赶全国人民平均生活水平这一特殊时期,应采取政府主角—市场配角模式,三箭齐发：破解经济底子薄弱难题,必须建立内生动力培育长效机制并推动库区经济高质高速发展;破解发展空间狭窄难题,必须跳出库区,在重庆全域范围内来重构生产力和城乡大格局;破解生态环境脆弱难题,必须由长江中下游生态受益区对三峡地区生态建设进行补偿。同时,要积极育新育大育强市场主体;充分发挥市场在库区微观资源配置中的决定作用。     

Bridge,Focus, Attack,or Stimulate: Retail Category Management Strategies with a Store Brand

We investigate a monopolist retailer's category management strategy where the main strategic decisions are how to horizontally position a store brand relative to the incumbent national brands and how to price the store and national brands for retail category profit maximization. We analyze a market composed of two consumer segments with differing tastes and heterogeneity with respect to willingness to pay and a product category consisting of two competing national brands and one store brand. We find that contrary to the existing literature, it is not always optimal for a retailer to position its store brand against the leading national brand; instead there are many situations where it is best to position the store brand close to the weaker national brand or to position it in the “middle” so it appeals to both national brands' target segments. In the process we identify four distinct category management strategies that a retailer can use with a store brand. In three of these the optimal store brand price is the brand's monopoly price, while in the remaining one strategy the price is lower. We also suggest an easy to implement means for a retailer to determine which strategy is best to use, depending on the particular competitive environment present before the introduction of the store brand and the relative quality of the store brand. We find that the store brand entry is most beneficial to the retailer when the national brands are moderately differentiated. Finally we show that introducing a store brand not only allows the retailer to garner a higher share of the channel profits through higher retail margins, but also often provides the retailer the benefit of increases in national brand unit sales as well as incremental sales from the store brand.
