This concept has the following four implications:
1 An important feature of modern marketing is to meet the needs of a wide range of users. The coal produced has not only raw coal, but also a series of product structures that meet various needs, as well as products for deep processing of coal. These all reflect the market demand is the source of life of coal companies; and the marketability of coal is the vitality of the development of coal companies. With the development of society, the deepening of reform and opening up, the gradual establishment of a market economic system, and the adjustment of the structure of coal products, the deep processing of coal is imperative. This is an inevitable requirement for the development of productive forces for basic energy and a necessary condition for the modernization of the coal industry.
2 Marx said: "Commodity can not go to the market itself, can not be exchanged by themselves." Through different modes of operation and mode of transport, coal products are transferred to the hands of users, and coal commodity circulation is realized. Our national coal operators are state-owned coal companies, collective coal companies, and individual coal operators. The various modes of ownership with public ownership as the main body are also varied. Many transport modes with railway transportation as the main body also exist objectively. This is a tool for the circulation of coal commodities. While coal's rail transportation accounts for more than 40% of the total railway traffic, China's coal resources are more coal than South coal, West coal is more than East coal, and the coal is delivered to users. The railway transportation capacity is a key factor. . The status quo of the Chinese railway is a unique one. Because of the shortage of railway transportation capacity, the state attaches importance to the development of railway transportation capacity. It is a requirement of the national economy and is also necessary for coal transportation and sales. This is one of China’s national conditions. Over the years, although the country has invested a lot of money in the development of railway transportation, road transport and other comprehensive modes of transport, its capacity still lags behind the development of the national economy.
3 The realization of coal commodity value and use value is the basic driving force for basic energy to ensure the development of the national economy, increase productivity, and expand reproduction. The value of coal commodities is determined by the necessary labor time for the production of coal, and the monetary expression of this value becomes the price of coal. The price formed according to the law of supply and demand is the market price of coal. Coal mines serve the users according to the use value of different coal products. The process of realizing value and use value is a concentrated expression of the operation of the market economy system; it is constrained by the three major laws of the market: the law of value, the elasticity of supply and demand, and the competition law of commodities; in turn, the use of these three laws is better. To realize the value and use value of coal commodities. The purpose of the circulation of coal commodities is to meet the production needs of the society, and to use the relationship between commodities and currencies, through pricing and payment, to implement voluntary equal exchanges between both parties, and to combine physical movements with capital operations so that coal production can realize the value of products. To achieve value compensation, promote social reproduction and the development of the socialist national economy, and maximize the satisfaction of people's material and cultural life needs. Therefore, the circulation process embodies the equality, mutual benefit, and cooperation between people. Coal commodities are both production data and life consumption data. Therefore, the good use of coal's value and use value is an important link in ensuring basic, sustainable, rapid, and healthy development of the national economy.
4 The role of bridges and bonds for coal transportation and distribution is a necessary condition for the expansion of reproduction; it is an important part of the allocation of materials and resources. Coal transportation and distribution are the leading enterprises in the coal industry. The operation of the coal companies has become a leader in diversified operations with coal quality as the basis and transportation and sales as the leader.
Coal transportation and sales include: coal market surveys and forecasts; coal sales channels; merchandise coal transportation and sales plans, merchandise coal purchase and sales contracts; coal product quality and pricing; commodity coal sales promotion; coal business negotiation and skills; coal storage and loading measurement; Coal sales and transportation dispatch (road and mine coordination); coal business disputes handling and litigation; coal sales diagnosis and consulting services; coal transportation and sales statistics; coal transportation and sales finance and audit; coal export trade; national macro-control business. Through these tasks, coal transportation and supply can provide high-quality commercial coal and services on the premise of determining market demand. In the chain of the socialist market economic system, it should play its due role.
