Abstract:

To improve the efficiency of forestry production is the basic requirement of sustainable forestry as well as one of the key tasks of constructing modern forestry. The authors used DEA to evaluate the comprehensive efficiency of input-output value of forestry, pure technical efficiency, scale efficiency and categories of scale values of forestry in 31 provinces (autonomous regions and municipalities). The results showed that Tianjin, Shanxi, Guangdong and Guizhou were relatively efficient in 31 provinces (autonomous regions and municipalities) of China as for the input-output aspect, which meant China’s forestry management was in low level on the whole, meanwhile the projection analysis was employed to analyze the input or output low efficiency reasons, the analysis found that the forestry inputs were deficient across the provinces (autonomous regions and municipalities) and forestry added values were great lower than the optimal targets, which hindered the forestry efficiency enhance. By virtue of the conclusion, some optimal measurements of forestry efficient improvement were put forward. i.e. only appropriate to change the provincial forestry industry structure, improve the utilization of forestry resources, it was possible to achieve the effective input-output efficiency of forestry.
