Aiming at the problem that the existing eco-environmental pollution economic cost assessment method has low evaluation accuracy, an ecological cost assessment method based on grey theory is proposed. A grey relational degree function is constructed to analyze the correlation between ecological environmental pollution and economic cost. According to the results of correlation analysis, the factors affecting the economic cost of ecological environmental pollution are ranked according to the degree of correlation. The economic cost assessment framework of ecological environmental pollution based on two-step method is constructed, and the economic cost assessment of ecological environmental pollution based on gray theory is completed. Experimental results show that the accuracy of this method is always above 97%, it shows that the method in this paper has higher evaluation accuracy, and verifies the comprehensive practicability of the method in the evaluation of ecological environmental economic cost.
