Export trade and potential of Chinese sunflower seeds:An empirical study based on gravity model
China is the world's largest producer and exporter of edible sunflower seeds,and it is important to grasp its trade characteristics and export potential for the development of China's sunflower seeds industry.Based on the analysis of current trade situation and characteristic of Chinese sunflower seeds,the export potential of Chinese sunflower seeds was empirically analyzed using an extended gravity model based on the panel data of China and 19 export destination countries from 2001 to 2021.The results showed that Chinese sunflower seeds'export had high competitive advantages and the disadvantageous situation of export prices was gradually alleviated.The increase of GDP,economic freedom index and foreign trade dependence of agricultural products in export destination countries,the increase of bilateral trade distance and the narrowing of per capita GDP difference between two countries promoted Chinese sunflower seeds'export.The current trade potential of some Southeast Asian countries was under-utilized and the trade potential of some Middle East countries exceeded the target realization.It is suggested that China should align with international agricultural quality standards,strengthen the promotion of branding and scientific propaganda of nutritional knowledge,and explore high-end consumer markets for edible sunflower seeds at home and abroad.Meanwhile,China should consolidate and enhance its trade partnership with Middle East countries and improve its trade environment with the help of RCEP policy advantage to promote trade in small agricultural products with neighboring countries.
