摘要
经济高质量发展背景下,数字经济正成为推动中国产业结构转型的新动能。本文通过构建多部门经济增长模型,从效率型技术进步视角,阐述数字经济对产业结构转型的具体影响,并基于中国省级面板数据进行了实证检验。结果表明,2009—2018年中国数字经济发展迅速,但存在显著的“数字鸿沟”与区域不平衡特征;数字经济发展显著推动了中国产业结构转型,该结论在一系列稳健性检验下依然成立。异质性检验表明,东部和中部地区数字经济显著推动了产业结构转型,且东部地区的推动作用远远大于中部地区,而西部地区数字经济发展对产业结构转型的影响不显著;相较于2013年之前,2013年之后中国的数字经济发展更快,对产业结构转型的影响显著为正,且推动作用明显增强。传导机制检验表明,数字经济可以通过产业间技术进步差异有效推动产业结构转型。以上结论为中国加快推进数字化建设和产业结构转型提供了经验证据和政策启示。
Under the background of high-quality economic development,digital economy is becoming a new driving force to promote the transformation of China’s industrial structure.This paper constructs a multi sector economic growth model,expounds the specific impact of digital economy on the transformation of industrial structure from the perspective of efficient technological progress,and makes an empirical test based on China’s provincial panel data from 2009 to 2018.The results show that from 2009 to 2018,China’s digital economy has developed rapidly,but there is a significant“digital divide”and regional imbalance;the development of digital economy has significantly promoted the transformation of China’s industrial structure,and the conclusion is still valid under a series of robustness tests;the test of regional heterogeneity shows that the eastern and central regions’digital economy has significantly promoted the transformation of industrial structure,and the eastern region’s driving role is far greater than the central region,while the western region’s digital economy has no significant impact on the transformation of industrial structure;the heterogeneity test shows that compared with that before 2013,the development of digital economy in China after 2013 is faster,which has a significant positive impact on the transformation of industrial structure,and the driving effect is significantly increased;the transmission mechanism test shows that digital economy can effectively promote the transformation of industrial structure through the difference of technological progress among industries.The conclusions of this paper provide empirical evidence and policy implications for China to accelerate the digital construction and industrial structure transformation.
