Financial risk assessment of six regions in China under the TOPSIS model based on a coupling perspective

As China's economy enters a new normal, the gradually changes from high speed to quality, and task of resolving various types risks in each region becomes more arduous, while prevention control regional financial will certainly become one severe challenges faced under economic normal. Based on parallel data six regions China, this paper combines EWM subjective weights AHP objective construct EWM-AHP coupling weights. It also adopts distance between ideal point superiority inferiority solution (TOPSIS) ranking method quantify relative relationship sample evaluation criteria establishes differentiated risk indicator model for regions. The results show that is lower with weaker base level development. Financial higher degree openness. integrated TOPSIS models can effectively reduce development process improve smoothness operation, which has particular application value. backward development, index sound capital market
