Abstract:Carbon peaking and carbon neutrality goals have boosted manufacturing investments in green innovation, which has a dual contribution to the economic performance and social responsibility of manufacturing companies. From the perspective of knowledge management, we develop a moderated moderation model to ivestigate the effects of user participation, knowledge distance, and knowledge integration mechanisms on corporate green innovation in this study. Based on the survey data of 197 manufacturing enterprises, the data analysis are made by using SPSS23.0 and PROCESS macro, we find that: 1) There is a positive relationship between user participation and enterprise green innovation; 2) Knowledge distance negatively moderates the positive correlation between user participation and enterprise green innovation; 3) The interactive mechanism, rather than the programmed mechanism, can mitigate the negative moderator effect of knowledge distance. Henceforth, a new explanation for the complex relationship between user participation and enterprise green innovation is proposed by articulating the possible moderating mechanisms under the combined action of knowledge distance and knowledge integration mechanisms. Besides, our study provides some new insignt how the enterprises can effectively utilize user resources, also provides guidance for the manufacturing industry to take measures to promote green innovation and promote the sustainable development.
