文摘This paper takes the imports of animal-derived food as the example,and uses the 6-digit-code HS data of the CEPII BACI database ranging from 2002 to 2018 in an extended gravity model to study the impact of the sanitary and phytosanitary(SPS)measures implemented in China on the import trade and trade margins of animal-derived food.The results show that(1)China’s SPS measures have not significantly restricted the import trade of animal-derived food but rather enhanced import trade by alleviating negative externalities and information asymmetry;(2)SPS measures have positive effects on the extensive,price,and quantity margins for developed countries;while(3)SPS measures have negative effects on the quantity margin for developing countries.Thus,China’s SPS measures have not yet constituted a trade restriction.
