Abstract: In the context of digital economics, responsible digitalization practised by enterprises is an important path to promote the development of science and technology in the right direction and to achieve compatibility between digital transformation and green development. The fulfillment of corporate environmental responsibility is often plagued by issues such as“too much talk and too little action”, “drifting green”, and“decoupling”. Based on the micro data of A-share listed companies from 2011 to 2019, this paper explores the impact of corporate digitalization level on corporate environmental responsibility of “less talk and more action”and its boundary conditions. The findings indicate that the digitalization level has a significant promoting effect on corporate environmental responsibility in a“less talk and more action”way.Under high environmental pressure, the level of digitalization has a stronger promoting effect on corporate environmental responsibility of“speaking less and doing more”. When enterprises face higher financing constraints, the promotion effect of digitalization on their environmental responsibility of“speaking less”is weaker. The promotion effect of digitalization level on“less talk”mainly affects the low-quality disclosure of enterprise environmental information rather than high-quality disclosure. The promotion effect of digital level on corporate environmental responsibility will not sacrifice the financial performance of the enterprise. The above research conclusions reveal the close connection between enterprise digitization and enterprise green development, providing important insights for achieving the two major social goals of digital transformation and green development.
