Protectionism or let go? Evidence from IT investment in Chinese manufacturing firms

From a global perspective, economic and trade disputes between countries are gradually increasing. Under the influence of the COVID-19 epidemic and war, the competition among the countries has become more intense. Lower trade barrier for economic cooperation or trade protection is becoming a concerned topic for governments and researchers around the world. This study uses the IT investment data from Chinese manufacturing enterprises from 2015 to 2022 to test the impact of international competition on technological development under environmental heterogeneity. The research results show that the external environment has an important impact on the technology performance of enterprises. After the COVID-19 epidemic, the IT investment performance of enterprises shows a “productivity paradox” situation. Further research shows that reducing tariffs and introducing international competition will be conducive to the development and utilization of IT by enterprises, which is supported in different market environments. This study verified that lowering trade barriers and introducing international competition to achieve win–win cooperation is still an important method for economic and firm development.
