Purpose: The purpose of this study was to assess green innovation as a mediating variable in the relationship between green supply chain management and firm performance.Design/methodology/approach: This study used the companies listed on the PROPER program for the 2010-2018 period on the Indonesia Stock Exchange. The sample collected by using purposive sampling method obtained 488 companies. The data were tested using STATA 16.Findings: The results of the analysis showed that green supply chain management had a positive effect on green innovation, green innovation had a positive effect on firm performance, and green supply chain management had no effect on firm performance. Green innovation mediated the relationship between green supply chain management and firm performance.Research limitations/implications: The limitation of this study was using companies listed on the PROPER program, so it needed to be studied by applying other companies. Besides, it only implemented green innovation, green supply chain management, and firm performance. Future studies can apply other green-related aspects and performances.Practical implications: Regarding the problem of environmental impact, companies in Indonesia can apply green innovation and green supply chain management to improve their firm performance. Companies in Indonesia are increasingly faced with pressure from stakeholders to implement green supply chain management.Social implications: It is useful for the Indonesian government in overcoming environmental impact issues by implementing green supply chain management by companies. Companies that implement green supply chain management will have an impact on increasing green innovation and firm performance.Originality/value: This study assessed the mediation of green innovation in the relationship between green supply chain management and firm performance.

Indonesia’s government policy recommends that medium and large companies carry out corporate social responsibility programs. These programs provide sustainability for the company because they can involve community social relations, economic growth, and increasing environmental awareness. This study aimed to test corporate social responsibility on firm performance with green innovation as a mediation. This study used PROPER companies in 2015–2019, which were chosen using a purposive sampling method involving annual reports and financial reports, yielding 253 companies as a sample. Data were obtained from the Indonesia Stock Exchange and tested using STATA. This study indicates that corporate social responsibility can increase green innovation in companies with the stability of environmentally friendly materials, emission reductions for the surrounding community, and saving energy use. Corporate social responsibility has a positive effect on firm performance because the company has maintained the continuity of the process. After all, it has a harmonious relationship with the community. Furthermore, green innovation positively affects firm performance because the company can reduce energy use and utilize environmentally friendly resources. Therefore, green innovation can mediate the influence of corporate social responsibility and firm performance. This research contributes to senior managers who are part of their company’s top management to understand the critical role of corporate social responsibility in maintaining the company’s sustainability by paying attention to the part of the company’s environment and implementing government regulations. Corporate social responsibility can maintain good stakeholder relations and increase green innovation and firm performance. Theoretical contributions can enrich research related to the context of sustainable performance.

The objective of this study was to measure or assess competitive advantage in mediating the effect of green innovation on firm performance. The data in the study were PROPER companies for the 2010-2018 period and the sample was selected using purposive sampling so that 369 companies were obtained. The results of this study proved that green innovation had a positive effect on competitive advantage, the competitive advantage had a positive effect on firm performance, green innovation had no effect on firm performance, and competitive advantage mediated the effect of green innovation on firm performance. In reducing environmental problems, companies can apply green innovation to increase the company’s competitive advantage and firm performance.

This study examines the effect of green supply chain management (GSCM) on firm performance, with competitive advantage as mediation and board size as moderation. Purposive sampling method was used to examine 516 PROPER companies from 2010 to 2018. Data were obtained from the Indonesia Stock Exchange. Results show that GSCM has a positive effect on competitive advantage but does not affect firm performance, whereas competitive advantage has a positive effect on firm performance. Moreover, competitive advantage can mediate the relationship between GSCM and firm performance. Board size cannot moderate the relationship between GSCM and competitive advantage, but it can moderate the relationship between competitive advantage and firm performance and the relationship between GSCM and firm performance. The results of this study can be used to improve firm performance of companies concerned with environmental impact. The research findings contribute to the idea that board size has a role in strengthening the implementation of GSCM to create competitive advantages that can increase firm performance.

The application of social performance as a material for transparency of environmental commitments that drive company management on company performance is required in the firms.

The results of the study revealed that green supply chain management mediated the effect of corporate social responsibility on firm performance, green innovation did not mediate the effect of corporate social responsibility on firm performance, green supply chain management mediated the effect of corporate social responsibility on green innovation, and green innovation did not mediate the effect of green supply chain management on firm performance.
