China's Coal Industry Chain Of Economic Fluctuations

China is one of the countries which are relying on coal industry in the world. The coal industry plays very important role in their national economy, and now there are some turning changes. With the development of our coal market and the supporting of our government, the coal industry is facing a good development. But there are also some reasons which affecting the coal industry besides our country's policies, for example, the foreign trade policies which make a challenge and difficult position. So our government public different policies to dissolve the capital, such as payable use the coal, the recycling industry of experimental unit, the whole market of electricity, the merging of industry and so on in 2006. At the new age, we should extend the chain of coal, develop the clean technical of coal, and realize the long use at the end. So this is a chance for the development of coal industry. The same as the other industry, the coal industry has its own cycle, and we should develop different coal industry and non-industry at different stage. Now the value of non-coal industry is more than that of coal industry, so many enterprises began to develop non-coal industry quickly, through changing their construction of organization, the fixation of products, the way of developing specialized talent and so on.In this text, through combining with Cycle Theory, I want to find the nature and math relation between coal industry and non-coal industry. That's because at the moment, the coal industry is facing a favorable circumstance and the relevant chain of coal industry also influence the economic fluctuation of the coal industry's period. This text is based on the development of XX group-company's coal industry and non-coal industry, and also based on the analysis of relevant coal industry, in order to find the relevance, similarity and lag of coal and non-coal industry. In the end, I will give some constructive suggestion for the future development.
