Abstract:

Based on the straw resource utilization input-output data of 932 farmers in Shandong Province in 2018, this study evaluated the performance of straw resource utilization using three-stage data envelopment analysis (DEA) model. The study found that: (1) Before excluding the influence of external environment and random interference, the mean value of farmers’ comprehensive efficiency was 0.5422, the mean value of pure technical efficiency was 0.7048, and the mean value of scale efficiency was 0.7693. After excluding the influence of external environment and random interference, the mean value of farmers’ comprehensive efficiency was 0.5075, the mean value of pure technical efficiency was 0.9044, while the mean value of scale efficiency was 0.5611. The decrease of scale efficiency is the main reason for the decrease of comprehensive efficiency of farmers’ straw resource utilization. (2) There are some differences in the performance of farmers’ straw resource utilization between different regions. Before excluding the influence of external environment and random interference, the ranking of comprehensive efficiency of each region was Dezhou>Heze>Weifang>Liaocheng>Jining>Linyi. After excluding the influence of external environment and random interference, the ranking of comprehensive efficiency became Heze>Dezhou>Weifang>Liaocheng>Linyi>Jining. The performance of farmers’ straw resource utilization in Dezhou and Jining is more influenced by external environment and random disturbances. (3) The regression results of the stochastic frontier approach (SFA) model show that government technical training and financial subsidies, guidance from professional economic cooperatives, and farmers’ knowledge of straw resource utilization methods and technologies can significantly reduce the waste of farmers’ inputs such as direct production materials, labor, and human capital, and improve farmers’ performance of straw resource utilization. Overall, the performance of farmers’ straw resource utilization in the main straw-producing areas of Shandong Province is relatively low, and it can be improved by expanding the scale of straw utilization and improving the external environment such as technical training and financial subsidies.
