贸易便利化对黄河流域农产品出口二元边际影响的空间效应

Abstract:With the development of economic globalization and international trade，trade facilitation has gradually become the core element of new global economic and trade rules. This article is based on the inherent requirements of economic dual circulation and ecological protection and high-quality development in the Yellow River Basin. By constructing an indicator system to comprehensively evaluate the level of trade facilitation in provinces along the Yellow River，and utilizing binary marginal effects，the role of the constituent elements of trade facilitation in different dimensions of trade growth is refined and decomposed，and the spatial spillover of the impact is analyzed. Research has found that trade facilitation levels characterized by infrastructure quality，business information technology efficiency，customs and trade environment，government management，and financial service quality all have a positive promoting effect on the intensive margin of trade in the Yellow River Basin，and the impact is significant.
