Analysis on Influencing Factors of China's Service Export Trade Volume Based on Multiple Regression Method

In recent years, China's service trade has developed rapidly, but behind the high growth, there is a long-term deficit in service trade. With the increasing role of service trade in a country's economy, how to promote the development of China's service trade and improve the deficit plays an important role in China's economic development.

Through the establishment of the model and descriptive statistics, this paper understands the basic situation of the data, intuitively analyzes the preliminary relationship between variables through scatter diagram, through regression analysis Statistical inference, economic significance test, econometric test and correction, get the final reliable model, and give relevant policy suggestions according to the results.
