Research on the Impact of Land Border Opening on Trade Efficien-cy Between China and Neighboring Countries-An Analysis of Bor-der Areas as"Dual Circulation"Hub Nodes
The opening up of border areas has facilitated the cross-border flow of factors between China and neighboring countries,becoming a new driving force for improving trade efficiency.This study is based on the theo-ry of inter-regional trade and regional economic integration,innovatively constructing the Border Region Openness Index,and using a stochastic frontier gravity model to test the correlation between the level of openness in China's border regions and the trade efficiency between China and neighboring countries.The results indicate that the over-all trade efficiency between China and the 14 neighboring countries is still at a relatively low level,and border open-ing has a significant positive impact on the trade efficiency between China and neighboring countries,with this ef-fect being more significant in the northwestern border region.
