Abstract:

Due to the input-output data are interval numbers in interval data envelopment analysis(DEA), the production possibility set(PPS) used as the evaluation reference may not be consistent with the production point of the evaluated decision-making unit(DMU), which leads to positive and negative spillovers in interval efficiency evaluation. Based on the existing interval efficiency DEA model considering the unity and comprehensiveness of the evaluation, an efficiency compensation mechanism is proposed, and an interactive efficiency evaluation model is constructed based on the best and worst PPS by setting compatible constraints, which reduces the positive and negative spillovers to a certain extent. Subsequently, the spillover of the evaluation results is expressed through the definition of the degree of likelihood between the general interval efficiency and the benchmarking interval, and the accessibility of the decision unit efficiency in conjunction with the spillover degree is defined. The benchmarking in terms of effectiveness and accessibility is defined, which makes the benchmarking construction adaptable to a variety of decision-making environments. Due to the fact that the input-output data of forest carbon sinks is not an accurate value, treating this input-output data as interval numbers is more in line with the actual situation. The method proposed in this article is very suitable forevaluating the efficiency of forest carbon sequestration in China. Choose the forest carbon sink data from remote sensing measurements in 2017 and forestry related data from the same year to evaluate the performance of forest carbon sinks in 30 provinces of China.Based on the efficiency evaluation results, 8 provinces were selected as benchmarking. The results show that these 8 provinces have economic, resource, or management advantages in the development of forest carbon sink, which provides guidance for the development path of forest performance management in China and has practical reference value.
