The main issues of the research are put as following : firstly, with the international comparing of market sharing rate and trading competitive index, it was revealed that wheat in china has inferior international competitiveness with a bit rising during current years, however, which is still behind that of the main wheat export countries. secondly, after the international comparing of the main factors that affect the international competitiveness of wheat, it was discovered that chinese wheat has the obvious cost advantage on unit product, while because of the high circulation fee, it results in inferior advantage on the price ; low and unstable quality is another factor which leads to inferior wheat competitiveness ; the input of fertilizer and labor makes little impact on the productivity of chinese wheat, while the input of seeds, irrigation and machine makes a strong impact, so it should be more invested in seeds, irrigation and machine to reduce wheat ' s unit cost. the assistant industries of the wheat, such as breed, production materials and processing industries, have inferior international competitiveness and lagged development
