Adjustments in VAT rates and business innovation: Empirical insights from China

Abstract

China aims to alleviate corporate financial pressures and encourage high-quality economic development through initiatives such as value-added tax (VAT) rate reform. This study employs the difference-in-difference (DID) approach to investigate the effect of the 2017 VAT rate reform on corporate innovation, taking the reform as a quasi-natural experiment. We find that the VAT rate reform has significantly promoted firm innovation and that increasing profitability serves as the primary channel. The innovation-promoting effects of the VAT rate reform are most prominently seen in a number of different types of businesses: those with lower intermediate input ratios, those operating in less monopolistic industry environments, state-owned enterprises, non-exporting businesses, entities with limited financial resources, and companies located in non-eastern China. This study makes a case for tax reforms in other nations as well as a reference for China's market-oriented reform and further VAT reform.
