A New Sustainability Index System and Evaluation Model Based on the GA-BP Neural Network Model

摘要

This paper aims to evaluate the sustainability of the country using mathematical methods. First we select nine indexes from natural resources, economic strength, human resources and social living environment in total to establish the index system for sustainable development and validate the completeness and independence among indexes. We randomly select ten countries as the sample data, and build an evaluation model based on the GA-BP Neural Network Model [1] which has the advantage in assigning weights objectively, and define a mathematical standard for sustainability. The evaluation results of this model is similar to the conclusion of World Bank.
