Abstract: As a key component of supply-side structural reform, the replacing business tax with value-added tax (VAT) and tax rate simplification policies drive collaborative innovation and industrial transformation between the service and manufacturing sectors through tax deductions and optimized tax rates. Using A-share data from 2009 to 2021, this paper employs a quasi-natural experiment to examine the effects of VAT reform, finding that both replacing business tax with VAT and tax rate simplification significantly enhance the service industry's labor productivity and total factor productivity, thereby promoting its transformation and upgrading. This paper focuses on the deep interactions between producer services and manufacturing, overcomes the limitation of analyzing replacing business tax with VAT and tax rate simplification in isolation, quantifies their contributions, and verifies their synergistic role in fostering new quality productivity. Notably, from the perspective of industrial interaction and collaborative innovation, this study distinguishes the policy effects on producer versus consumer services and finds that replacing business tax with VAT and tax rate simplification significantly advance service industry upgrading through the dual channels of increasing the demand of the manufacturing sector for the service sector and alleviating financing constraints in the service sector. Thus this paper underscores the critical role of VAT reform in the formation of new quality productivity.
