近年来互联网已逐步成为影响贸易的关键因素,在加快推进我国出口转型升级的背景下,深入分析互联网内生贸易条件下的出口增长边际效应,寻找新出口增长点具有重要意义。通过对Melitz(2003)模型的基本框架进行扩展,将互联网对贸易的影响内生化,重点探讨互联网对出口增长三元边际的影响,并以2005—2015年中国21个主要出口地区数据为样本,对理论模型的结果进行计量检验,结果发现互联网能够使我国出口增长广度和数量边际增加,同时降低价格边际,且其对出口增长广度的影响更为显著。
In recent years, the Internet has gradually become a key factor affecting trade. Under the background of accelerating the transformation and upgrading of China’s exports, it is of great significance to analyze in depth the marginal effects of export growth under the condition of Internet endogenous trade and find new export growth points. Through the expansion of the basic framework of Melitz (2003) model, the paper analyzes the impact of the Internet on trade and highlights the impact of the Internet on the ternary marginal growth of exports. Based on the data of 21 major export regions in China from 2005 to 2015, The results of the theoretical model test results show that the Internet can make China’s export growth breadth and quantity increased marginally, while reducing the price margin, and its impact on the breadth of export growth even more significant.
