Research on the Impact of Fixed Asset Technology Depreciation Policy on Digital Transformation

This paper investigates the impact of the accelerated depreciation policy for fixed assets on the digital transformation of enterprises. By constructing a multi-period difference –in -differences model and using data from Shanghai and Shenzhen A-share listed companies from 2011 to 2020, it is found that the accelerated depreciation policy for fixed assets significantly promotes the digital transformation of enterprises. The study also verifies the reliability of the results through robustness tests and heterogeneity analysis, and explores the differentiated impacts of the policy on enterprises in different regions, ownership attributes, and scales. Additionally, the mechanism effect analysis reveals that the policy indirectly promotes the digital transformation of enterprises by alleviating financing constraints and enhancing enterprise performance levels.
