Abstract:

【Objective】This study introduces the back-feeding mechanism, considers the benefit of back feeding for paper making and marketing subjects to forest management subjects, and explores a new path of effective benefit distribution and stable symbiotic development of a green supply chain for forest to the paper.【Method】Based on the theory of system dynamics, the forest to the paper green supply chain is built as a cooperation alliance, and the causality diagram is drawn, with relevant variables extracted, the system flow diagram drawn, the values of relevant variables calculated and the variable equation designed. Multiple benefit feedback proportion schemes are designed, and the change trend of the overall and individual benefits of the forest to the paper green supply chain are analyzed through a dynamic model simulation.【Result】Under the benefit feedback schemes, the overall economic, ecological, and individual benefits of the forest to paper green supply chain were higher than those of the non-feedback scheme. From the perspective of individual benefits, it is preferable to choose the fixed proportion Ⅰ scheme in which papermaking and other entities feed back the sustainable elements of 10% of the symbiotic income of the forest management entities annually, rather than the variable Ⅰ (20%,16%,12%,8%,4%) proportion scheme, in which papermaking and other entities feed back the forest management entities annually, and the proportion of back-feeding is low. From the perspective of overall benefits, the scheme of variable proportion Ⅱ (30%,25%,20%,15%,10%) is preferred, where the proportion of back-feeding of papermaking and other entities to the main body of forest management changes annually, and the proportion of back-feeding is high.【Conclusion】The back-feeding scheme is better than the non back-feeding scheme. From the perspective of the overall benefits of the green supply chain for forest to paper, the higher the proportion of back-feeding, the greater the benefit. From the perspective of the individual benefits of the green supply chain, when the back-feeding proportion is close to the scenario, the variable-proportion scheme is better than the fixed-proportion scheme. From the perspective of the individual benefits, the proportion of back-feeding should not be too high. While selecting a scheme, the core enterprise takes the lead, and multiple subjects participate in the discussion to select a satisfactory scheme.
