Evaluation of International Import and Export Complexity Based on Trade Gravity model

The trade Gravity model is widely used in international trade. Starting from understanding the complexity of international trade imports and exports, this article established a model of influencing factors on imports and exports by analyzing import and export trade data. This article found that these factors have a significant impact on the complexity of international trade. This paper also discussed that the construction of the trade Gravity model can help better understand trade relations and trade policies. Through experiments and data investigation, the complexity of trade import and export was analyzed. The data results showed that China's exports to the United States amount to 38706 trillion yuan and imports amount to 11833 trillion yuan. This partially indicated that China's economic situation is improving. The research results can provide important references for international trade policies. By analyzing the data, this article found that the complexity trends of import and export countries are similar. A prediction model for the total import and export trade volume was further established, which can better predict the scale and trend of trade.
