The Benefit Evaluation Of Sand Industry Based On Value Chain

Desertification control is an important part of the construction of ecological civilization.Improving land desertification through the development of sand industry is one of the main directions of desert control,at present,however,there is a lack of literature to evaluate the development of sand industry by empirical research.Benefit as important indexes to measure the enterprise production way and business operation result,can reflect the status of development of sand industry,value chain is the sand industry the important reflection of internal production and operation activities,therefore,studying the comprehensive benefits of the sand industry from the perspective of the value chain,can more comprehensively reflect the current benefits of the sand industry,which is of great significance to the development of China's sand industry.This article taked some sand industry enterprises in Ulanbuh desert and Khorchin desert as the research object,firstly deconstructed the sand industry value chain on the basis of investigating and analyzing the current situation of the sand industry,found that the planting industry was the main industry mode of sand industry.Finally,constructing the comprehensive benefit evaluation index system of the sand industry,and the comprehensive benefit level of the sand industry was deeply discussed from three aspects of economic benefit,social benefit and ecological benefit by using the method of entropy value and grey relational degree.It was found that the economic benefit,social benefit,ecological benefit and comprehensive benefit of the extended sand industry of Yilizhongxinnong group were higher than the other two sand industries.The three sand industries were affected by indicators such as profit margins,resource consumption per unit of revenue,and employment driven by the sand industry.Based on the above conclusion,this paper focused on economic benefit,social benefit and ecological benefit,put forward some policy suggestions,such as avoiding rough large-scale production,reasonably arranging enterprise expenses,increasing investment in agricultural science and technology,and increasing government support and policy subsidies.
