Trade countermeasures to prevent and control biological invasion.
At present, the research about bio-invasion and trade countermeasures in China only focuses on the relationship between bio-invasion and international trade. There are few researches about how to use economic model to predict and analyze the economic consequences of potential trade counter-measures. The national and international studies on trade countermeasures against bio-invasion were summerized via the analysis of literatures in terms of biological invasion and international trade. The paper proposed that more studies should be conducted in terms of how to use trade countermeasures like tariffs, subsidies, prohibitions and the more to control bio-invasion based on the researches results achieved abroad, and trade model should be used to predict and analyze the economic consequences of potential trade countermeasures. Besides, a professional and practical database on bio-invasion should be established to provide the basis and reference for government decision-making in terms of bio-invasion control.
