Market Share Of Chinese Corn In Major Importors And It's Changes

This paper mainly analyzes domestic and international corn trade patterns, particularly market share of china in corn importing countries. Firstly, summarizing the evolution of domestic corn trade pattern, then discussing the domestic corn trade flows and channels, and develops a simple corn demand index to analyze corn flow trend. As china entering WTO and it's grain market integrated into international market,"Nan Liang Bei Yun" and "Nan Jin Bei Chu" has becoming the main pattern. Secondly, the paper discusses Chinese corn international trade partem and the role of Chinese corn in world corn economy, according to the Chinese corn production, stock and trade volumes.Besides, a framework market share analysis is applied to analyzes Chinese corn exports, by calculating"distribution"effect,"competitive"effect and "size of markef'effect in the given time periods. The results show that"competitive" effect is more important for Chinese corn export than other effects.Finally, in order to analyze the impact of competition among exporting counties, a third country effect model is developed. Considering the country effect to minimize a specification bias problem that arise from the fact the unilateral trade flows depend not only on the costs of purchasing grain from an exporting country but also on the costs of purchasing grain from competitions of the exporting country. In the model ,exchange rate and volatities in exchange rates as main variables, the result indicates that U.S exchange rate against importing countries is significant for corn export market shares of china. Based on above analysis and discussion on other corn market problems, some conclusions and suggestions are provided.
