互联网对省际贸易的影响--基于引力模型的研究

hina has put forward to the establishment of a "dual circulation" development pattern in which domestic economic cycle plays a leading role while international economic cycle remains its extension and supplement. The domestic circulation as the main body highlights the advantage of China\'s super market scale and the potential of domestic demand. The inter-provincial trade index can reflect this situation to a certain extent. This paper uses the relevant data of China Transport Yearbook and Statistics database of National Bureau to build the inter-provincial trade database, as well as to empirically analyze the impact of Internet on inter-provincial trade and its influence channels at the time of the Internet of Things based on the gravity model. The results show that the development of Internet has played a significant and steady positive role in inter-provincial trade. Firstly, it has significantly increased the volume and value of inter-provincial rail freight by allowing more enterprises to enter the e-commerce market. Secondly, this effect is particularly significant in the western region of China, which effectively improves the unbalanced situation of regional development in China. Accounting for endogeneity and with the use of substitution tests, the results remained robust. The above findings complement the relevant empirical experience of China\'s trade mode.
