Moreover, due to the lack of a unified operation platform, the industry information transmission is not smooth and the efficiency of information transmission is low. In the coal supply chain finance, the main body participating in trade financing generally adopts one-way information transmission mode, that is, the coal sales enterprises cannot obtain the necessary information of coal mining, freight transportation and other aspects in time, and cannot reasonably arrange their own production and operation, and the level of up-down transmission of information in the chain is relatively low.. To a certain extent, the complexity of the coal industry aggravates the degree of information distortion and distortion. It is unable to realize the effective transmission of information from the source to the final receiver, which makes the inaccurate information be enlarged without reason, leading to the "bullwhip effect".
