Trade friction early warning model based on big data classification algorithm

Abstract

The present invention relates to the technical field of economic operation monitoring system, especially to a trade friction early warning model based on a big data classification algorithm. The method of the model comprises the steps of: the step 1: constructing data mark and trade friction system index and trade friction system index groups; the step 2: constructing an expert scoring model; thestep 3: constructing an SVM classifier; the step 4: training a classification model; the step 5: arranging a trade friction early warning interval; and the step 6: determining an application model prediction result and an application model prediction result interval. The method provided by the invention is based on the statistics theory, combines the newest data excavation theory enforcement method, employs the expert scoring assessment model and an analytic hierarchy process and takes historical data as a basis of model construction to achieve rapid, scientific and objective calculation of atrade friction index result; and moreover, an interval classification algorithm is provided by the model to calculate a trade friction risk grade interval to provide a trade friction risk prediction for the calculated trade friction result.

Description

technical field [0001] The invention relates to the technical field of economic operation monitoring systems, in particular to a trade friction early warning model based on a big data classification algorithm. Background technique [0002] Trade friction refers to the process of trade between countries in international trade, resulting in trade balance, generally a country's continuous surplus, another country's deficit, or a country's trade activities Touch or injure the industry of another country. [0003] The current situation of international trade friction presents two new features: (1) it is on the rise; (2) it is becoming more and more intense. Going up a step means going up the third step. The first step is tariff barriers and administrative protection measures. The WTO has resulted in significantly lower tariffs for all members and has worked to remove administrative protection measures. Therefore, this primary form and means of trade friction has been greatly ...

AI Technical Summary

Problems solved by technology

[0005] The existing trade friction index considers more policy factors, and the lack of intervention of other factors will lead to a certain deviation in the data results, and the calculated results lack a trade friction risk level range reference

[0006] In the traditional solution, the trade friction index is based on many policy factors, and then manually calculates and evaluates. Therefore, there is a certain degree of subjectivity, experience differences, missed judgments, and misjudgments in the evaluation process. Perfect, the calculated results are not objective and lack scientific basis
