Research on the effect of government subsidies on productivity of IOT enterprises——An Empirical Study Based on Data of Listed Companies from 2016 to 2018

In recent years, the rapid development of the IOT industry is closely related to government subsidies. This paper conducts an empirical research based on data of listed companies from 2016 to 2018 by panel fixed effect model to test the effect of government subsidies on total factor productivity of listed companies. The empirical results show that government subsidies significantly promote the total factor productivity of IOT listed companies and show a significant inhibitory effect after a oneyear lag. Finally, the paper discusses the corresponding countermeasures and Suggestions, in order to provide beneficial ideas for the development of China's IOT industry.
