Analysis of contribution to climate based on DEA and AHP

Abstract

With the increasing shortage of resources and energy, the traditional GDP cannot reflect the comprehensive economic strength of the country, so the GGDP has attracted great attention from the governments of all countries and the international community. This paper developed an evaluation model for the impact of human activity on climate change. The human activities affecting climate are summarized as industrial production activities, agricultural production activities, human reproduction, transportation and man-made disasters, and the index system was established from these five aspects. The objective weight of the index is calculated by DEA, the subjective weight of the index is calculated by AHP, the comprehensive weight is calculated by game theory empowerment, and finally the score of the impact of human activities on climate change is calculated by TOPSIS. Mining GGDP model indicators and the common influencing factors of human activities, to improve the influencing factors as a decision variable, establish linear planning model, update the calculation results of the price model index data, get new national scores and previous policy implementation, through paired sample t test proved that the climate change before and after the implementation of the significant differences.
