Abstract:
The purpose of this independent study aimed to investigate the relationship of the variables that affected cargo volumes of imports and exports between Thailand and South China (Yunnan). By various factors from in - depth interviews of the companys imports from China (Yunnan) and the companys exports to China (Yunnan), the analysis was conducted by creating multiple regression equation and forecast data series using monthly data from January 2007 - September 2015. All three prediction methods consisted of Exponential Smoothing, Moving Average and Decomposition. Then select the forecasting method that provides minimal errors, forecast the volume of imports and exports between Thailand and South China (Yunnan) during 2015 - 2019.
The relationship between the volume of cargo (Dependent variable) with other variables (Independent variable) found in imported value that correlated with cargo volumes of imports from China, at a confidence level of 95 percent. Export products without any independent variable was correlated with the volume of exports from Thailand, at a confidence level of 95 percent. The most appropriate forecasting technique was the Decomposition method. The forecast data showed that, in the fourth quarter, Thai imports had a great number of products from China, This is the seasonal index equal to 1.8428. In the third quarter, Thailand exported had a great number of products to China, which had the highest seasonal index of 1.4482. Forecast trends in the volume of cargo between Thailand and South China (Yunnan) were both imports from China and exports of Thailand, where the downward trend was continued.
