Abstract:

Reaction of China's soybean import prices to the changes of import structure determines the stability of domestic soybean prices. This paper makes an empirical analysis on the effects of import structure changes on China's soybean import prices by PTM model, based on unit root test, F test and other statistical tests. The results show that the increasing market share of U.S. and Brazil helps reduce China's soybean import prices, while Argentina's improving share in soybean market tends to raise China's soybean import prices. In order to import soybean at lower prices, China should continue to maintain U.S. and Brazil as its import source and on the other hands protect and promote domestic soybean production through technical support and other ways.

Key words: import price, import structure, imperfect competition, PTM model, soybean
