Abstract

This paper has divided a country into two systems: economic system, environmental system. On the basis of Development evaluation system from United Nations and our analysis, we determined first grade metrics of sub-systems. Then, based on first metrics, we specified second grade metrics and defined the method of calculating first grade metrics to make first grade metrics is positive to sustainable development of sub-systems. After getting specific metrics, we built Linear Evaluation Model for each sub-system. Then based on data from World Bank, we chose 130 countries who have complete data set to calculate the weight of each first grade metric by using entropy method and MATLAB. The specific weights we got are (0.2449,0.1331,0.1175,0.0998,0.2625,0.1422),(0.2566,0.1615,0.2292,0.1165,0.2362). The Static Comprehensive Evaluation Model is the sum of the Linear Evaluation Model of each sub-system. Based on the definition of sustainable development and our metrics, we get overall evaluation model, we can easily find the difference between different developing countries, so ,it can be used give one country advice to become more sustainable by the metric system. 1. Build overall model 1.1 The evaluation equation to whole system In this paper, one country involve three part: economic sub-system, environmental sub-system, it is obvious that every sub-system is important for one country’s development, environmental sub-system represents the potential development and competitiveness in future, economic sub-system represents one country’s immaterial influence in different areas now. So we can use these three sub-system analyze one country’s sustainable development. P = PE + PO 1 Where, P denotes National Sustainable Development Index, PE denotes Economic Sustainable Development Index, PO denotes Environmental Sustainable Development Index 1.2 Determine influence of different sub-system Step1: calculate Standardized matrix We use Standard-Deviation Method to construct Standardized matrix:
