However, in most consumer markets a business should serve the middle class by competing in the mid-price segment, offering quality better than that of the competition at a somewhat higher price. It is this path that can lead to market share leadership: a strategy that can be both profitable and sustainable. The U.S. men's shaving cream market consists of two major product-market segments: gel and foam. We test the hypothesis that the best-selling brand is very likely to be a member of the mid-price segment with a price tag that is higher than that of the nearest competition. This study is based on annual U.S. sales data for 2008 and 2007 from discount retail stores, food stores, and drug stores. We performed two separate analyses for 2008 and 2007, using cluster analysis as the main analytic tool. The results were remarkably consistent between the two years. In the gel segment--by far the most important--the price-quality segmentation analysis supported our hypothesis. An interesting finding is that, for both the gel and foam segments, we found the rank order correlation of brand unit price between 2007 and 2008 as highly significant. This means that in this market management considers the price of a brand as a strategic rather than a tactical variable. Although, technically the results for the foam segment were negative, this does not necessarily contradict our hypothesis. Finally, we discovered six strategic groups in the industry and have tried to articulate what their competitive strategy is.展开更多

This has played a positive role in economic development, however, since stepping into a large country economy, entering the.WTO and the current development of economic globalization at a rapid rate, the leading export strategy has already been very difficult to adapt to the daily challenges in export because of the constant changes in domestic and international economic environment. In view of this, China should turn its strategy into one of dynamic comparative advantages with a global competitive strategy, in conformity with big country's economy in the economic background of globalization.展开更多

During the period of less than four years, it has completed two big electrolyticaluminum smelters and started the construction of a project of oxide of alumina. With its rapid speed, advanced technology and equipment, and high efficiency, the company has created a miracle in aluminum industry. From the viewpoint of strategic management, the author analyzes the strategic thinking of its entry into the aluminum industry; the strategic measures to build the company into the most competitive enterprise in this industry, and how to maintain a sustainable competitive advantage. Meanwhile, the paper plays an important reference role for the analysis of the private economy, and the enterprises with diversified thinking and those wishing to expand aggressively.展开更多

The OM and the remanufacturer compete in the product market. We examine the effects of government subsidy as a means to promote remanufacturing activity. In particularly, we consider three subsidy options: subsidy to remanufacturer, subsidy to consumers, and subsidy shared by remanufacturer and consumers. We find that the introduction of government subsidy on remanufacturer or consumers always increases remanufacturing activity. We also find that subsidy to remanufacturer is the best subsidy option, because subsidy to remanufacturer results in lower price of remanufactttred products, thus leading to higher consumer surplus.展开更多

We investigate a distinct form of GB, namely consumer-driven group buying, whereby some consumers form purchase groups to visit stores together and negotiate for discounts. We refer to these consumers as GB consumers that differ from regular consumers who visit stores individually and pay regular prices. Visited by a purchase group, a store has to make an immediate decision to serve their demand in its entirety. Turned down by the first store it visits, the purchase group continues to visit the other store. After accommodating GB demand, the stores use remaining stocks to serve regular consumers. We demonstrate that GB can be a treat to stores that adopt proper policies to utilize it as an instrument to reach consumers. The stores are able to accommodate group demand at a price lower than regular price in most circumstances but still manage to earn stable profits. The presence of regular consumers has a subtle effect on equilibrium formation, by strengthening the stores' power in negotiating with GB consumers to make group price weakly increase with group size. Moreover, competing stores are able to manipulate the interactions between purchase groups and collectively earn a higher total profit than a monopolist store when GB consumers account for a small fraction of market base and competition is intense.展开更多
