Research on the Dynamic Evolution Model of the Influence of Foreign Trade on Economic Resilience Level Based on Triangular Fuzzy Entropy

As an important indicator of economic development, the degree of opening to the outside world measures the dependence of a country or region on foreign trade and foreign capital, which plays an important role in promoting economic growth and adjusting economic structure.On the contrary, regions with high dependence on foreign capital can show strong economic resilience.In this paper, the optimal weights of indicators are determined by the combination of the entropy value method of objective weighting and the triangular fuzzy method of subjective weighting.A dynamic evolution model of comprehensive economic evaluation based on the combination weighting is established.By evaluating indicators of criterion layers such as sustainable development and economic structure, the principle of the square sum of deviations between one indicator and another indicator is adopted.The multi-attribute comprehensive evaluation value of each evaluation object is dispersed as much as possible, so as to reflect the difference of index comparison more clearly, and change the situation that the index difference is not obvious due to the average weight in the existing portfolio empowerment research.In addition, it also adopts the research methods of literature research, comparative research, normative analysis and empirical analysis, and analyzes the degree of openness to the outside world into the degree of import dependence, export dependence and foreign capital dependence, and empirically explores the influencing factors of economic resilience from the above three perspectives, The results show that the main and objective weights are 0.471 and 0.529.Through empirical analysis, it can be seen that export dependence and import dependence have a significant negative impact on regional economic resilience, while foreign capital dependence has a significant positive impact on regional economic resilience.In the post-financial crisis period, when economic fluctuations are severe, the positive impact of foreign capital dependence on economic resilience is significantly increased.
