Abstract: After analysis on symbiotic system of the forestry low-carbonization industrial chain, this paper developed the framework of the symbiosis system. The characteristics of the low-carbonization forestry industrial chain was composed of community, material input dematerialization, ecology and economic value-addition. Similar motivation mechanism existed in each unit of the symbiosis system. Using the forestry processing and manufacturing unit as an example, it was assumed that the forestry processing and manufacturing unit consists of pulping, papermaking and panel manufacturing enterprises, and a function between resource consumption(utilization of segmentation and category of forestry resource, non-forest resource consumption and waste recycling), production input and output could be proposed. The mathematical solution to this function showed that each enterprise will get more profits when they are combined in the symbiosis system, and the overall income of the symbiosis system would exceed the sum of these three individual enterprises. Research results showed that the individual enterprise would take part in the industrial chain with passion when they expected to obtain incremental gains from the symbiosis system in the forestry low-carbonization industrial chain than from the independent operation. Finally, several proposals were presented in this paper, such as the forestry industrial chain should extend itself in order to enlarge the symbiotic enterprise scope, the material input dematerialization should be propelled in the physical manufacturing symbiotic unit, and novel symbiotic models should be explored further.
