Antidumping investigation initiated by EU has been a serious problem which heavily affects bilateral trade development between China and EU. This paper probes whether there exists a long-run and short-run relationship between China exports to EU and antidumping investigation by employing ARDL model and bounds testing techniques. Utilizing quarterly series data from 1995 to 2009, we conduct an econometric analysis and find that there really exists cointegration relationship among four level variables, namely exports, GDP, commodity prices and the numbers of antidumping investigations. In terms of long run effects, antidumping investigation initiated by EU does not constitute trade barriers, on the contrary it plays positive effects on export although the effects are weak. The level of national income also shows positive effects on export. However, commodity price exhibits a negative impact although its coefficiency is not statistically significant
