Green innovation has become an important way for manufacturing enterprises to achieve sustainable development. Existing research on green innovation mostly focuses on conceptual content, and relevant empirical studies only involve individual indicators. Systematic measurement tools are still lacking. Therefore, drawing on the theoretical framework provided by the social-ecological system, a clear definition of the connotations of green innovation and an exploration of the dimensional structure

... nd scale development of green innovation in enterprises are the core objectives of this study. Strictly adhering to the process of scale development, four core dimensions of green innovation in enterprises are identified, and a scale with 18 items was established. The results show the following: (1) The connotations of corporate green innovation should be expanded to include not only technology and product innovation but also internal institutional innovation and external environmental innovation. (2) Green innovation in enterprises should be measured in a rigorous manner, and such measurements should follow the logic from goals to behavior. (3) The scale of green innovation should be refined, and questions should be designed to characterize specific green innovation behavior indicators. In summary, this study lays a foundation for quantitative research on green innovation in enterprises and provides a useful reference for manufacturing enterprises to improve their level of green innovation.
