Research on the Impact of Industrial Policy on the Innovation Behavior of Strategic Emerging Industries

Cultivating strategic emerging industries (SEIs) is an important strategy for most countries around the world to seize the economic frontier. Academics have not yet reached a unified conclusion on whether the adoption of industrial policy from the government level can effectively promote its R&D and innovation behaviors and contribute to industrial upgrading. Based on the data regarding 33,425 Shanghai and Shenzhen A-share-listed companies from 2007 to 2020, this article employs the difference-in-difference model (DID) and the mediated effect model to identify the effect and mechanism of how industrial policy affects the innovation behavior of SEIs. The results of this study show that the promulgation and implementation of industrial policies can help stimulate enterprises to carry out R&D and innovation behaviors and improve the innovation level of SEIs. Its promoting effect on state-owned enterprises is more significant than that on non-state-owned enterprises, and its promoting effect on the eastern and central regions is more significant than that on the western region. Further analysis reveals that government subsidies and tax incentives are important transmission mechanisms through which industrial policy affects firms' innovation, with government subsidies playing a positive facilitating role and tax incentives having a negative impact.
