            Correlative Analysis of Yanbian's Primary Forestry Industry and Sub-industries

            Xinning LI  Yufen XU  
            【摘要】:By selecting three indicators(timber cultivating and planting,timber harvesting,forest products),this paper uses grey relational degree to analyze the correlation between Yanbian's primary forestry industry and sub-industries. Results show that there is a decline in the relational degree of three indicators concerning Yanbian's primary forestry industry,but the relational degree of timber harvesting is still high and the relational degree of forest products is slightly increased.
