数字经济驱动中国出口多元化异质性研究

Research on the Diversification and Heterogeneity of China's Export Driven by Digital Economy

面对百年未有之大变局,数字经济对贸易的影响日益凸显,为高水平开放下中国大力开拓出口多元化提供了方向指引。数字经济与各行业的融合,为参与国际分工模式带来了新的机遇,积极推动出口多元化是当前中国经济实现高质量发展的重要动力。选取2013―2019年中国省级面板数据,构建数字经济指标体系,利用固定效应模型,将样本按照贸易方式和区域进行划分,探讨数字经济对出口多元化异质性影响。实证研究表明,数字经济发展水平越高的省份,其参与国际分工越会采取多元化的战略,且东部地区的效应大于中西部地区,同时数字经济对出口多元化的影响存在贸易方式的异质性。

In the face of unprecedented changes in a century,the impact of the digital economy on trade has become increasingly prominent,providing guidance for China to vigorously develop export diversification under the high-level opening up.With the integration of the digital economy and various industries,it has brought new opportunities for participating in the international division of labor model,and actively promoting export diversification is an important driving force for China's economy to achieve high-quality development.In this paper,we plan to select China's provincial panel data from 2013 to 2019,construct a digital economy indicator system,use the fixed effect model,divide the samples according to trade patterns and regions,and explore the impact of the digital economy on the heterogeneity of export diversification.Empirical tests show that the higher the level of digital economy development,the more provinces will participate in the international division of labor to adopt a diversified strategy;the effect of the eastern region is greater than that in the central and western regions;the impact of the digital economy on export diversification has heterogeneity in trade patterns.
