平台经济驱动我国数字产业国际竞争力提升路径

The Path to Enhance the International Competitiveness of China's Digital Industry Driven by Platform Economy

选取2009—2021年中国31个省级面板数据,运用固定效应模型与中介效应模型实证分析平台经济对我国数字产业国际竞争力的影响与作用机制。研究发现,平台经济快速发展有利于提升我国数字产业国际竞争力,在经过内生性问题处理与一系列稳健性检验后该结论仍成立。作用机制检验发现,平台经济通过增加研发投入与促进产业结构转型两大路径,提升数字产业国际竞争力。异质性分析表明,2018年以后平台经济对东部、中部、西部地区的数字产业国际竞争力赋能作用更强。据此,应全方位推进平台经济建设,增强研发投入成果转化力,打造产业结构转型推动力,实施差异化平台经济发展战略。

Select the 31 provincial level panel data of China from 2009 to 2021,and empirically analyzes the impact and mech-anism of platform economy on the international competitiveness of China's digital industry using fixed effect models and intermediary effect models.Research has found that the rapid development of the platform economy is beneficial for enhancing the international comp-etitiveness of China's digital industry,which is still valid after addressing endogeneity issues and conducting a series of robustness tests.The mechanism test found that the platform economy enhances the international competitiveness of the digital industry through two major paths:Increasing research and development investment and promoting industrial structure transformation.Heterogeneity studies show that the platform economy has a stronger role in empowering the international competitiveness of digital industries after 2018 and in the eastern,central,and western regions.Based on this,we should comprehensively promote the construction of platform economy,enhance the trans-formation of research and development investment results,create a driving force for industrial structure transformation,and implement a differentiated platform economy development strategy.
