PROBLEM TO BE SOLVED: To comprehensively evaluate agricultural management. A management data acquisition unit acquires data (analysis data) of actual values related to a plurality of types of management resources input to agriculture in a target farmer (S12 to S16), and a first index value calculation unit Based on the probabilistic frontier production function, the existing data stored in the existing farm DB, and the acquired analysis data, the first index value for evaluating the efficiency of agricultural management is calculated (S18). In addition, the productivity calculation unit and the second index value calculation unit calculate the second index value for evaluating the productivity of each management resource based on the analysis data and the existing data (S20 to S24). Then, the display screen creation unit creates an evaluation comment for evaluating the agricultural management using the first index value and the second index value (S26), and displays the evaluation comment, the first index value, and the second index value. A screen is created (S28) and output to a terminal via an output unit (S30). [Selection diagram] FIG. 7
