采用国内资源成本系数(DRCC)、显示性比较优势指数(RCA)、净出口显示性比较优势指数(NR-CA)、国际市场占有率(MS)、贸易竞争系数(NTB)5个指标对我国油菜生产的比较优势及油菜产品出口的国际竞争力进行了测算。结果表明:我国油菜生产不具有比较优势,油菜籽及菜油总体为净进口,国际竞争力较弱,油菜籽出口的竞争劣势明显,菜籽油出口略有竞争优势;进而从国内资源禀赋状况及技术水平、加工业状况、国内市场需求三个方面分析其原因。
We use the five indicators of domestic resource cost coefficient (DRCC), display comparative advantage index (RCA), net export display comparative advantage index (NR-CA), international market share (MS) and trade competition coefficient (NTB) The comparative advantages of rapeseed production and the international competitiveness of rapeseed exports were measured. The results showed that the rapeseed production in our country did not have the comparative advantage. The rapeseed and rapeseed oil were net imports in general. The international competitiveness was weaker. The competitive disadvantage of rapeseed export was obvious. The rapeseed oil export had a slight competitive advantage. Technical level, processing industry status, the domestic market demand analysis of the three aspects.
