Firms in Globalization: Evidence from China Supervisor: LI Yao / ECON Student: LI Xinzi / ECOF LI Yaxuan / ECOF YANG Jingdian / MAEC Course: UROP1100, Fall UROP1100, Fall UROP1100, Fall This paper investigates the trade pattern between the firms in Fujian Province, China. Firstly, it explores the trade pattern of the firms of different sizes mainly in three dimensions: the number of firms, the trade volume and the number of transactions. Secondly, it gives some observations of firms’ overtime trade pattern. Finally, it offers ways to find the merging rate of firms recorded in customs data and trade data in Fujian Province. It concludes that all types of firms prefer to trade with small and micro enterprises and the increase of the number of firms is basically due to the “New entry” and “Exit”.

It complemented the previous gravity analysis on the bilateral trade among 142 countries in the world during 2010- 2018 respectively. More specifically, the research explored China’s export growth at the intensive margin and extensive margin during 2010-2019 respectively, and concluded that China’s export values mainly grow at the extensive margin, especially in product diversification. Lastly, it analyzed the dynamics of China’s exporting products entry, continuation and exit. Result shows that the income inflow has more potentials to grow and become more stable as the development of BRI policy deepens.
