Research on Global Common Balance based on 3DVA Model
摘要
This paper establishes a three-dimensional vector assessment model (3dva) to measure global equity. Firstly, this paper collects the data of 12 indicators from 20 countries, and divides the 12 indicators into three dimensions, namely, economic development level (ED), current situation of culture and Education (CE) and energy holding (EO). Then this paper combines analytic hierarchy process (AHP) and entropy weight method (EWM) to calculate the weight of these 12 indicators in their respective dimensions. Then, we build a three-dimensional vector evaluation model (3DVA), and place the values of the three dimensions as the components of the evaluation vector in the three-dimensional coordinate system. The modulus s of the evaluation vector represents the global equity of the country, and set the vector S_0 (1,1,1) is the standard modulus, representing the best degree of global equity. Finally, this paper uses the model to evaluate the global equity of 20 countries, obtains the evaluation vector s of 20 countries, and compares the modulus |S| of 20 countries with the national development level index for sensitivity analysis. The ranking trend of the two is roughly the same, which proves that the 3dva model is correct, reasonable and feasible.
