A Study On Simulation And Optimization The Relationship Between Foreign Trade Structure And Foreign Trade Competitiveness Of Zhejiang Province

Foreign trade structure and foreign trade competitiveness are always the hot subjects of research in academia, but the dynamic relationship between foreign trade structure and foreign trade competitiveness is still relatively few in research. With the economic development and the increase of the complexity of foreign trade environment, it has realistic significance in the research of the dynamic relationship between foreign trade structure and foreign trade competitiveness.In this paper, firstly, the foreign trade structure of Zhejiang province is analyzed by foreign trade general complexion, export and import trade structure, foreign trade spatial structure. And the foreign trade competitiveness of Zhejiang province is analyzed by foreign trade dependency, normalized trade balance, export advantages to thicken index, foreign trade Hirschman Index. So the basic learning data for the simulation model of the relationship between the Foreign trade structure and foreign trade competitiveness is acquired. Secondly, the BP neural network is selected, and the simulation model of the relationship between the foreign trade structure and foreign trade competitiveness is designed when the topological structure of BP neural network, activation function and learning speed are ensured. In order to make the data can be analyzed expediently, the origin data which be analyzed by BP neural network is normalized and the output data is un-normlaized. Then the precision of the simulation model of the relationship between the foreign trade structure and foreign trade competitiveness is tested by the Empirical Study on Zhejiang province. The result of the test is that the precision of the simulation model is fit the request and it can be used to analyses the. effect of the foreign trade structure change on the foreign trade competitiveness. Thirdly, the experiment data about the effect of the foreign trade structure change on the foreign trade competitiveness of Zhejiang province is calculated by eight simulation experiments. Then the conclusion is analyzed. Fourthly, in order to raise foreign trade competitiveness, the six countermeasures are put forward to optimize the foreign trade structure.
