Analysis Of Coal Logistics Efficiency And Influencing Factors In Coal Enrichment Area

With the reform of China’s energy supply side and the continued advancement of coal production capacity,the optimization of the coal industry structure has become the core proposition of energy and economic development.The “Coal Development Plan” promulgated by the National Development and Reform Commission and the National Energy Administration clearly proposes a coal logistics development strategy for building a scientific layout,high-efficiency and smooth flow,coordinated support,and energy conservation and environmental protection.Affected by the distribution of coal resources,coal production centers and coal consumption centers are dislocated,resulting in a long-distance,high-cost transport pattern for coal in China.Therefore,the study of the efficiency of coal logistics in coal-enriched areas is not only an urgent need for the development of the coal industry in coal-enriched areas to break through the development difficulties,but also an important path for adapting to the economic and new energy economy reforms,and it is also a guarantee for accelerating the construction of a modern coal logistics system.This paper takes the coal enrichment area as the research object,takes the coal logistics efficiency in the coal enrichment area as the research issue,starts from the coal logistics status in the coal enrichment area of our country,and defines the coal enrichment area according to the related theories of regional industry logistics and industrial efficiency.The concept and connotation of coal and coal logistics efficiency;Based on the current status and problems of coal logistics in the current coal enrichment area,based on relevant data of China’s 12 major coal production areas from 2011 to 2015,using DEA-CCRand BCC models to build coal enrichment District coal logistics efficiency evaluation model,from the comprehensive efficiency,pure technical efficiency,scale efficiency,returns to scale and projection analysis of the five aspects of coal enrichment zone in-depth analysis of coal logistics efficiency.The main contents are as follows:(1)According to the definition of coal enrichment area,Shanxi,Shaanxi,Inner Mongolia,Guizhou,and Xinjiang were selected as representatives to analyze the status and problems of coal logistics in coal enrichment areas.(2)Using BCC and CCR models to measure coal logistics efficiency in coal-enriched areas,longitudinally analyze efficiency changes,explore the current status and trends of coal logistics efficiency,and laterally compare the efficiency of coal logistics in five provinces,so as to objectively and fairly evaluate the efficiency of coal logistics in all provinces and regions.And analyze the reason for the existence of the production distance.(3)According to the results of the efficiency analysis,the five basic factors of the location,business structure,informationization level,human resources input,and economic development level of the five provinces and regions of the coal enrichment area from 2011 to 2015 were chosen as variables,and Tobit was used to measure the economy.The model analyzes the influence of the above factors on coal logistics efficiency from a deeper level.The study found that:(1)The overall efficiency,pure technical efficiency,and scale efficiency of Shanxi and Inner Mongolia are all at a relatively high level;Shaanxi and Xinjiang are below the overall average level;Guizhou’s overall efficiency and pure technical efficiency are middle of the level,but the scale efficiency level is the lowest;In terms of scale of return,Shanxi and Inner Mongolia are moderately scaled,and Guizhou and Xinjiang can be appropriately scaled up.The scale of Shaanxi is not suitable for expansion.Projection analysis shows that there are redundant inputs relative to the remaining four provinces in Shanxi Province.(2)Location advantages,industrial structure,human resources investment,informationization level and economic development level are positively correlated with coal logistics efficiency.The correlation coefficient of impact degree is: 0.182163,0.040689,0.002556,0.001665,0.001355.This article focuses on the entire coal market in China.For the first time,the coal enrichment area is taken as the research object,taking into consideration the other major coal production areas,so that the results are more reliable,and the analysis is more comprehensive,realistic and effective;through the comprehensive coal logistics efficiency in the coal enrichment area Evaluate and analyze,and measure the impact of relevant influencing factors on the efficiency of coal logistics,and then put forward scientific and targeted recommendations for improving the efficiency of coal logistics in coal-enriched areas,and provide reasonable planning for coal logistics in coal-enriched areas and optimization of coal industry chain.The important practical significance also provides a scientific and rational basis for the formulation and implementation of policies for the coal enrichment zone.
