| Being the second-generation sources of irregenerated energy opposite firewood, coals must be present in the restriction of product life cycle that affects conditions of supply and demand. In the meantime, coals possess the most prospective reserves of original resources changing into improving resources, which conditions of supply and demand will be improved and which product life cycle will be extend with the vigorous development of science and technology. As a result, marketing straits faced by national collieries at present must be reexamined, in order to avoid long-term marketing tactful obstructions caused by lopsided viewpoint about coal product life cycle or short-term marketing tactful shortcomings caused by lopsided viewpoint about product improving process, which haven't any help with national collieries to break the back of marketing straits or to develop coal economies continually.Based on above mentioned viewpoints, this thesis on the hand probed into objective principle about interval suppressions of man-made replacing curves by analyzing users' price quoted methods, put forward short-term marketing tactic about bearing all fixed costs by former products to get into product replacing markets with variable costs. On the other hand this thesis picked up objective principle about interval implications of man-made improving curves by researching product improving data, put forward long-term marketing tactic about bearing all replacing costs by improved products to spread up original product markets with variable costs. In these analyses and tactics there's much that national colliery can make use of.Although this thesis only involved the analyses about PanZhiHua Coal Group's marketing straits, other national collieries in present are facing same contradictions between supply and demand. Although this thesis only put forward PanZhiHua Coal Group's short-term marketing tactics, other national collieries must deal with interval suppressions of man-made replacing curves. Although this thesis only put forward PanZhiHua Coal Group's long-term marketing tactic, other national collieries must comply with interval implications of man-made improving curves.However, it's both very difficult for former product to bear all fixed costs on the implementations of short-term marketing tactic and for improved product to bear all replacing costs on the implementations of long-term marketing tactic. Through investigations and analyses about PanZhiHua Coal Group's man-made profit unit divisions and PanZhiHua Steel Group's product improving technology replacements, this thesis put forward measures for bearing fixed costs and replacing costs according to present and future technology standards, which have fair theoretical inspiration and proper practical significance for national colliery marketing.This thesis suggested that uncontrolled raw coal fixed costs should be stripped from unit examining bases and original product market should be seized to make up raw coal fixed costs on the support of clean coal washing cost superiority. This suggestion actually reflect scientific thought about unit examining bases, which is much worth for financial theory and marketing practice.Although product improving is particularly important for PanZhiHua Coal Group, overwhelming majority facts of product improving faulty remind us to find product improved faulty causes. This thesis explained that investigation overlook about product markets, especially about earlier stage projects, is the key to these question according to a host of facts. Therefore, PanZhiHua Coal Group and other national collieries must devote much attention to marketing investigation.Extraordinary different with other primary product marketing, current coal product marketing contains many product quality and construction problems, however, this thesis made some resolutions through many experiments. Corresponded with current sophisticated product marketing, future coal product marketing will probably confront decision effectiveness problems accordi... |
