“…On the other hand, the parameter method is represented by the stochastic frontier analysis method (SFA) [12,13]. Compared with DEA, SFA incorporates the classical white noise, and fully considers the in uence of random factors, describes the production front through the production function parameter method, and decomposes the residual term into random error and ine cient parts, which has the advantage of identifying random factors, due to the need to set the model in advance, the model setting directly affects the accuracy of the measurement [14,15].Because these factors are consistent with the essential characteristics of agricultural production, the robustness of agricultural productivity estimates is better than that of DEA estimates.…”
