Under the requirements for the goals of"carbon dioxide peaking and carbon neutrality"and high-quality develop-ment strategies,how to effectively use digital innovation to drive green development has become an important practical problem to be solved urgently.Based on the observed data of manufacturing enterprises from 2013 to 2020,text analysis and word frequency statistics were used in this paper to measure enterprise digital innovation.The comprehensive index system of green development of manufacturing enterprises was constructed from three dimensions:economic profit,social value and environmental benefit.This paper studied the impact of digital innovation on the green development of manufacturing enterprises,the effective digital in-novation intensity threshold,the supporting effect of entrepreneurship and the fiscal and tax policies on the green development driven by digital innovation.The findings of this paper are as follows:(1)Overall,digital innovation has a significant positive impact on the green de-velopment of manufacturing enterprises,and there is a significant industry heterogeneity effect.The driving effect of digital inno-vation on green development is mainly concentrated in agricultural and sideline food processing industry,paper and paper prod-ucts industry,general equipment manufacturing industry and electrical machinery and equipment manufacturing industry.(2)The threshold effect of digital innovation intensity on the green development of manufacturing enterprises is significant.Only when the digital innovation intensity exceeds 141.707 can the green development of manufacturing enterprises be significantly promo-ted;otherwise,either the digital innovation effect is not significant,or the digital innovation will inhibit the green development of enterprises.(3)Entrepreneurial innovation spirit and entrepreneurial environmental protection spirit have a significant supporting effect on the green development of digital innovation-driven enterprises,but the entrepreneurial social responsibility spirit weak-ens the promoting effect of digital innovation on the green development of enterprises.(4)Tax incentives negatively regulate the driving effect of digital innovation on enterprises'green development,but the regulatory effect of financial subsidies on digital in-novation to drive green development is not significant.These conclusions will provide a new way and practical inspiration for manufacturing enterprises to use digital innovation to drive green development.At the same time,they will also provide some theoretical inspirations for designing effective fiscal and tax policies,choosing appropriate digital innovation intensity,shaping excellent entrepreneurial innovation spirit and entrepre-neurial environmental protection spirit.
