In this paper a kind of market competition mechanism for commercial municipal public enterprises is proposed; a price competition model of municipal public enterprises with similar products is founded; its static and dynamic game analysis is offered and a comparison between them is made. The results show that,for the business type of municipal public enterprise market competition mechanism can be introduced to mobilize the enterprise activity to raise the end of efficiency; the government may control the market price through the economic measures of regulating the amount of subsidy;that enterprises enter the market and select the price simultaneously is more advantageous than entering the market one after another in general, information among the municipal enterprises is symmetrical (the equilibrium is lower); "following enterprises" gets "second mover advantage";to raise the difference of the same product will increase the profit of enterprise.展开更多

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

The author proposes that there are two types of strategic interaction settings relevant to disclosure： capacity competition and price competition. Capacity competition drives firms to disclose more information to attain financial market valuation-related benefits, while price competition drives them to disclose less to protect long-term product market advantages. The author finds that the type of product market competition affects the level of voluntary disclosure over and above the finn＇s external financing needs documented in the previous literature. That is, firms engaged in capacity competition disclose relatively more information than those in price competition. Further analysis shows that capacity competition firms disclose more information than no-strategic-interaction benchmark firms but that price competition firms do not disclose less information than the benchmark firms.展开更多

This paper presents one kind of power-exchanging transaction model among price-varied power plants, which will be beneficial to price-varied power plants without any loss of profits of them and guarantee state-owned assets profits in minimum loss with no promotion of average price limit by power plants. Under ideal conditions, the computation results showed the sufficiency and necessity of power-exchanging transaction and maximum similarity with the requirements of optimized resources disposition in economics. The presented model is shown to be full of practicability and has been used in some part of power market.展开更多

Moreover, simulation of spot price scenarios and evaluation of energy contracts performance, are also necessary to the decision maker, and in particular to the trader to foresee opportunities and possible threats in the trading activity. In this context, computational systems that allow what-if analysis, involving simulation of spot price, contract portfolio optimization and risk evaluation are rather important. This paper proposes a decision support system not only for solving the problem of contracts portfolio optimization, by using linear programming, but also to execute risks analysis of the contracts portfolio performance, with VaR and CVaR metrics. Realistic tests have demonstrated the efficiency of this system.展开更多

This brings rare opportunities while huge challenges for Chinese offshore oil engineering enterprises. Chinese offshore oil engineering enterprises have made rapid development in recent years, but they still have a certain gap with European and American competitors. Only by answering the time＇s call for developmentof international market and having the courage to participate in international competition could Chinese offshore oil engineering enterprises gnaw strong unceasingly.展开更多
