贸易引力模型的演进与中国出口贸易

The Evolution of Trade Gravity Model and China's Export Trade

贸易引力模型探究了国家与国家间贸易流量的影响因素。随着国际经济学的发展,贸易引力模型的构造日益完善,理论基础日渐丰满。运用贸易引力模型,可以测算影响中国对外贸易的阻力因子及其对我国贸易二元边际的影响,为我国推进全面对外开放提出了加强国际交流以提供丰富的出口信息、推进基础设施建设以克服地理障碍、加强国际协调以消除贸易壁垒、鼓励国际合作以推动技术创新的新要求。

Trade gravity models explore the factors influencing trade flows between countries. With the development of international economics, the structure of trade gravity models has been increasingly perfected, and thus the theoretical basis gets more completed. Based on trade gravity models, we can measure the resistance factors of China＇s trade and their impacts on China＇s trade dual margins. The exploration and exploitation of trade gravity models could help promote China＇s overall opening up, as well as suggesting China strengthen international communication, provide abundant export information and promote infrastructure construction to overcome geographic barriers.
