THE MEDIATION EFFECT FIRM PERFORMANCE ON GREEN INNOVATION AND FIRM VALUE: EVIDENCE THE MINING INDUSTRY

Global warming is currently an issue that is widely discussed of both the accounting literature and others. The topic of environmental performance is gaining increasing attention from academics and politics when it is associated with each country’s policies regarding environmental damage. Purpose: This article to investigate both the direct and indirect the effect of green innovation and firm value on financial performance as mediating variable Design/methodology/approach: The samples in this study are applied using purposive sampling ad obtained total sample of PROPER participating companies listed in Indonesia Stock Exchange during the year of 2012-2018. The data used in this study are secondary data obtained from annual report. Companies are listed on the Indonesia Stock Exchange in mining industry in 2012-2018. The variable green innovation was measured by using PROPER, the financial performance was measured by ROA and the firm value were measured by Tobin’s Q. Data processing uses SEM-PLS with WarpPLS 6.0 with the consideration that SEM-PLS is a reliable tool for testing predictive models.

Research limitations: this article only examines green innovation using the PROPER measure while the green innovation measure is thought to be related to company value such as ISO 14001, content analysis is not discussed at all in this article and the research sample is limited to mining companies. This scope may not be able to describe the overall conditions in Indonesia. originality/value: This study comprehensively examines both direct and indirect effect of green innovation with financial performance and firm value, which is rarely examined in extant studies.


Introduction
Environmental innovation is now an issue discussed in the accounting literature and others. This topic increases from academics and politics when it is related to each country's policies regarding environmental damage [1]. Environmental damage which is caused by the implementation of mining activities that do not pay attention to environmental conditions has caused an increase in the area of critical land [2]. Walhi East Java reported on its official in 2016 there were 608,913 hectares of forest land in East Java experiencing environmental damage due to excessive exploitation of mines. Walhi Aceh recorded the total area of critical land in Aceh to be 460,099 hectares in addition to damaging the coal mining ecosystem in Bengkulu, causing damage to the watershed, resulting in reduced clean water supply [3].
Increasing cases of environmental damage due to mining activities are becoming a concern of the business world, because people are increasingly concerned about social and environmental issues, thus demanding companies to carry out social and environmental responsibilities. This encourages the creation of green innovation to reduce environmental damage [4] [5]. Environmental performance is the company's effort to meet the expectations of various stakeholders for the availability of transparent and accountable information. This is consistent with stakeholder theory which concludes that environmental stewardship is interpreted as a form of corporate communication in bridging and harmonizing the different interests of stakeholders [6]. Several studies reveal the motivation of companies to do green innovation, namely external party pressures and the availability of corporate financial resources in allocating environmental costs, reveals OECD Countries (Austria, Denmark, Finland, France, Germany, Italy, Japan, the Netherlands, Sweden, Switzerland, the United Kingdom, and the United States) carried out green innovation in the presence of political issues. Revealed an increase in purchasing power in Malaysia because the company has been producing environmentally friendly products. Companies that care about the environment in their operations get added value to attract investors [7] [8].
Green innovation is an indicator of company performance in creating better environmental conditions through effective and efficient management mechanisms. Green innovation is used in the company's operational activities in the form of environmentally friendly processes and products to enhance the company's competitiveness including innovation in technology, such as energy savings, pollution prevention, recycling, waste production or environmentally friendly company management [9]. Green innovation can improve company performance, because it reduces the environmental impact during the product cycle, meets market needs, is the key to achieving growth and environmental sustainability and helps companies deal with the environment to develop new market opportunities. Investment in the environment increases a company's burden in the short term, but increases future profits to increase investor confidence and confidence [10]. Company value can be seen from the movement of stock prices. If the higher the stock price is, the higher the company's value and the higher the attractiveness for investors or potential investors in investing their funds. The inconsistency of previous research raises the opportunity for variables that mediate the effect of environmental performance on company value, namely financial performance [11]. Financial performance is the main indicator of the management control system which has shifted from a financial performance model to a social and environmental performance model because it combines the expectations of various stakeholders, such as shareholders, customers, employees and so on [12] [13]. This research was conducted to determine the mediating effect of financial performance on the effect of green innovation on company value, bearing in mind that not all companies in Indonesia participate in government programs. In addition, the study was conducted to see the inconsistencies of the results with previous studies [14][15].

Theory of Stakeholder
Stakeholder theory helps company managers understand stakeholder environment in managing the environment more effectively and efficiently. Chang, (2011) and Doran & Ryan, (2016), revealed that the role of stakeholders is important when companies will conduct green innovations to reduce negative impacts on the environment, namely environmental issues involving the interests of various groups in society that can disrupt their quality of life, the era of globalization has pushed the traded products to be environmentally friendly. Investors tend to choose companies that own and develop environmental policies and programs and Social Institutions (NGOs) and environmentalists are increasingly vocal in criticizing companies that have not implemented green innovation (Osazuwa& Che-Ahmad, 2016). , revealed that a company that is run must produce improvements to the environment because at present it is impossible to work without caring about the community and the environment. Based on the description, this research develops the following hypotheses: H1 : Green Innovation has a positive effect on firm value

Green Innovation and financial performance
Stakeholder theory reveals that the company will inform all forms of responsibility for activities carried out related to the environment. Financial performance is an important indicator for investors in measuring the success of a company. Environmental performance of the company's efforts to reduce negative impacts on the environment. Investors expect returns on their investments. Return is obtained if the Corporate is able to produce good performance. . Environmental performance by Corporates to avoid protests or environmental penalties, increase productivity, enhance corporate reputation, foster green awareness, develop new markets, and achieve competitive advantage first mover (YS Chen et al., 2006). Referring to the theory and empirical evidence of previous research, the hypothesis in this study is H2 : Green innovation has a positive effect on financial performance

Green Innovation, Financial Performance and Firm Value
Financial performance is a key indicator of the management control system which has shifted from a financial performance model to a social and environmental performance model because it combines the expectations of various stakeholders, such as shareholders, customers, employees and so on (ER Freeman, 2018), shows that profitability has a negative effect on the firm value, this is due to the general view of shareholders regarding the prosperity obtained from their investments based solely on share prices rather than accounting earnings as informed by the company. Based on empirical evidence, the hypotheses in this study are: H4: Financial Performance has a positive effect on Corporate Value

Population and Sample
The population in this study is the mining industry registered on the Indonesia Stock Exchange in 2012-2018. Research samples are companies that publish annual reports and data used in this study are available. The sampling technique is to use saturated samples. Saturated sampling is a sampling technique when all members of the population are used. The company's annual report in this study is accessed from the website www.idx.go.id. The following Table 1 presents a list of the number of research samples. Green innovation refers to improvements in manufacturing processes and systems to reduce negative impacts on the environment, such as energy savings, pollution prevention, waste recycling and others (Dangelico& Pujari, 2010) measured using PROPER with a value of 1 to 5, 1 for companies that get black PROPER, 2 companies get red PROPER, 3 companies get blue PROPER, 4 companies get green color and 5, for companies that get gold PROPER, (Sarumpaet et al.  ., 2018). The method for calculating environmental performance based on the PROPER rating is as follows: Gold, environmental performance: very good, given a PROPER score =5 Green, environmental performance: Very good, given a PROPER score =4 Blue, environmental performance: good, given a PROPER score =3 Red, environmental performance: Poor, given a PROPER score =2 Black, environmental performance: very bad, given a PROPER score =1 Financial performance is the result of the achievements achieved by each company in running each of their businesses within a certain period of time in the financial unit. Company performance is measured based on financial performance, namely ROA (Return on Assets)

= Net profit Total Assets
Company value is the level of success of a company in managing its resources based on the assessment of investors. Firm value is measured based on market performance with tobin's q (Chung & Pruitt, 2007) The analysis used in the data processing in this study was PLS-SEM with statistical software tools WarpPLS 6.0 (Solimun & Ratmono, 2013). Partial least square method in this study aims to see the effect between variables. The independent variable is green innovation which is proxied by PROPER. Intervening variable financial performance which is proxied by ROA (Return On Asset). The dependent variable, which is the company's value is proxied by Tobin's Q. The statistical model of this study is: FVit = αo + β1GPIit.+β2FSit+ β3FAit+ ɛit FPit = αo + β1GPIit+ɛit

Inner Model Testing
Measurement of the inner model is intended to predict the role of financial performance on the influence of green innovation on firm value. Measurement of the inner model in terms of the adjusted R Square value is by considering the Q-Square value. The following inner model tests will be presented in Table 2 below: Based on Table 2 above, it is shown that financial performance or ROA has an adjusted R 2 value of 0.086 or 8.6%. This means that the green innovation variable is able to explain the company's financial performance of 8.6% while the rest is explained by other variables not used in this study.Firm value has an adjusted R 2 value of 0.483 or 48.3% which means that green innovation is able to explain the value of the company at 48.3% while the rest is explained by other variables not used in this study. Q-square value or commonly called stoner-geisser coefficient indicates that the independent variable in this research is Green Innovation which has good predictive validity because the Q-square value> 0.

Model Fit Testing
This study uses four fit model sizes including: Average Path Coefficient (APC), Average R-Square (ARS), Average Adjusted R-Square (AARS) and Average Block Variance Inflation Factor (AVIF). AARS is used to measure the average value of the path coefficient, R-squared and adjusted R-square produced in the model. The four sizes of the fit model are measured based on the required ρ-value ρ≤0.05 [67], [68]. While AVIF is used to test the collinearity problem in the PLS model it is required to be ≤ 5 but the recommended value is AVIF ≤ 3.3 [69].Testing the fit model is presented in Table 3 below. The test results in this study produce a fit model. Table 3, illustrates that APC, ARS and AARS have a value of ρ-value ≤ 0.05 and AVIF value ≤ 3.3 which indicates that there is no multicollinearity problem between the proxy and the variables used.

Hypothesis test
This research has two hypotheses to test the direct and indirect test using mediation variables. The results of the influence before and after the mediation variables are included are presented in Table 4. Table 4 shows that the direct influence of green innovation on firm value has a positive and significant effect on firm value. This supports H1 which states that green innovation influences company value. Financial performance mediates the influence between the green process of innovation and firm value, so that H3 is accepted.  Table 4 panel B, the indirect effect / mediation, shows that green innovation has a positive and significant effect on financial performance (path coefficient = 0.15 and p> 0.05), means accepting H2 stating that green innovation influences financial performance. Financial performance has a positive and significant effect on firm value (Path coefficient = 0.19 and p value <0.05), meaning that H4 is accepted. Financial performance increases the value of the company.

The effect of green innovation on Firm Value
Green innovation has a significant positive effect on company value. This shows that the green innovation carried out by the company is able to increase the value of the company. The results of this study are in line with research conducted by Rubera&Kirca, (2017); Sucuahi&Cambarihan (2016), revealed that if innovation is carried out by the company on an ongoing basis, the firm value will be better. A number of companies have carried out green innovation as evidenced by PROPER certification as a structured standard in implementing environmentally friendly programs.When companies express green innovation, the company is considered responsible for the environment. Thus, investor confidence in the company is increasing.
This study also explains that many companies in Indonesia have implemented green innovation. These companies are considered to have the ability to utilize their energy resources efficiently. Thus, the public and stakeholders are interested in buying their products. When the value of the company increases (seen from stock movements), the company's sales also show the same trend.

The Effect of Green Innovation on Financial Performance
Green innovation has a significant positive effect on financial performance. This shows that the better the company's green innovation, the financial performance will also be better. This finding is

Influence of Green innovation, Financial Performance and Firm Value
Financial performance is able to mediate green innovation on company value. This shows that the company's financial performance has an impact on increasing the value of the company. The results of this study support the stakeholder theory that companies must fulfill stakeholder rights related to information on company activities such as pollution, social movements and company business for safety in order to obtain support and face the level of competition between industries Gray et al. . Green innovation that has been carried out by the company is positively correlated with the company's internal and external interests. Thus companies become responsive to the environmental conditions in which they operate. One form of the application is the company's participation in environmental programs at the national and international level.

Effects of Financial Performance and Firm Value
Financial performance has a significant positive effect on firm value. This finding indicates that financial performance can increase the value of a company which is seen to be higher in stock prices. High profits from stock prices will attract investors to invest. This condition will positively influence the value of the company.  2016), revealed that the higher the profitability, the company has good prospects so that investors will pay more for the company.

Conclusion
The results of this study support stakeholder theory, companies are required to create environmental sustainability by carrying out various innovations in order to reduce negative impacts on the environment, revealed that the survival and financial performance is determined by the innovation strategy undertaken by the company and supports government programs to make the industrial estate environmentally friendly.
Green innovation is as a form of environmental strategy in financial and non-financial investment. One side of green innovation is considered a burden for companies, especially in developing countries. On the other hand will increase profits in the future, Financial performance is the main standard assessment of investors for companies in the internal and external environment. Guenster et al. revealed that green innovation plays a role in increasing company value. This is caused, because the company uses technology that is safe so that it does not cause negative impacts on the environment.
This study has limitations that can be taken into consideration for further research. First, the sample used is limited to mining companies. Second, the financial performance in this study only uses ROA (Return On Assets)). Third, the green innovation proxy is limited to companies that obtain PROPER. This can be a consideration for other studies interested in taking the topic of green innovation. Suggestions in this study are: first, further research in order to be able to add samples other than mining companies. Second, further research can use financial performance measures other than ROA. Third, further research can add measurement variables to green innovation, such as ISO 14001 and content analysis.
