Abstract

This study is aim to find out the contribution of intensive margin and extensive margin of Chinese aquatic products export. We construct a measure of the export margin and exploit export data of Chinese firms to analyze it, the result imply that intensive margin affect the export growth significantly, while the role of extensive margin is much important than intensive margin facing external shocks. We also find heterogeneity of markets and firms influence contribution of intensive margin and extensive margin differently: (i) intensive margin plays a positive and steady role in export growth which is imported by developing economies, while external shocks affect intensive margin negatively which is exported to developed economies; (ii) intensive margin and extensive margin of state-owned enterprises negatively impact exports in most years, while the contribution of intensive margin compared with extensive margin more pronounced on both private and foreign firms. However, the impact of external shock on intensive margin of foreign companies is more significantly.
