The effect of government 5G policies on telecommunication operators’ firm value: Evidence from China

To lead the world's fifth-generation mobile communication networks (5G) market, China introduced several policies to support 5G industry development that will impact telecommunication operators, the main implementers in this industry. Thus, this study examines the impact of the government's 5G policy announcements on telecommunication operators' firm value in China, where the state exerts a strong influence on industry development. We find that government policy announcement in general affects telecommunication operators' stock returns negatively, and when the government announces policies with a higher level of interference, the decline in firm value is more pronounced. To understand the comprehensive impact of 5G technology on telecommunication operators, we also examine the effect of institution-driven corporate technology R&D and investment activities on firm value. We find that the firms' 5G activities also decrease their firm value, and this effect is more significant than government policy announcements. These results imply that the market has a negative evaluation of the introduction of 5G technology due to its immaturity and uncertainty. This study provides a basis for understanding the market's views on 5G technology and development policies.
