Abstract

This exploration employs the generalized supremum augmented Dickey-Fuller (GSADF) approach to explore whether there are digital tech bubbles in China. The empirical results suggest the existence of multiple digital tech bubbles, which are mostly accompanied by an excessive rise. However, the appearance of digital tech bubbles is curbed since 2016, mainly due to the increasing mature regulations in relevant fields. Besides, bubbles in different digital technologies are similar during the same period, which could be attributed to the close relationships among them. Additionally, we further investigate the factors influencing the explosive behaviours, and find that the Chinese stock market positively affects digital tech bubbles, while economic policy uncertainties and situations negatively influence such explosive behaviors. In the context of the new round of scientific and technological revolution and industrial transformation, these conclusions provide valuable implications to achieve the target of constructing a “Digital China” by becoming moderately cautious about potential bubbles in the digital tech industry.

中国是否存在数字科技泡沫?

本文采用广义最优增广Dickey-Fuller (GSADF)方法来探讨中国是否存在数字科技泡沫。实证结果表明，数字科技存在多重泡沫，且大多伴随着过度上涨。然而，自2016年以来，数字科技泡沫的出现得到了遏制，主要原因是相关领域的监管日益成熟。此外，不同数字技术在同一时期的泡沫相似，这可以归因于它们之间的密切关系。此外，我们进一步研究了影响爆炸行为的因素，发现中国股市对数字科技泡沫有积极影响，而经济政策的不确定性和情况对这种爆炸行为有消极影响。在新一轮科技革命和产业转型背景下，对数字科技产业潜在泡沫持适度谨慎态度，为实现“数字中国”建设目标提供了有价值的启示。
