This study aims to analyze the influence between environmental performance,
environmental costs, and company size on financial performance with Corporate
Social Responsibility (CSR) as an intervening variable. The population used in this
study is manufacturing companies listed on the Indonesia Stock Exchange (IDX)
for the 2019-2021 period. A total of 38 out of 217 companies were sampled in this
study using purposive sampling techniques. The test was performed using two
regression equations, the first equation to determine the influence of independent
variables on intervening variables. The second equation is to determine the
influence of independent variables and intervening variables on dependent
variables. The Sobel test is used to test the effect of mediation between independent
variables on dependent variables. The results of the first regression equation test
show that environmental performance has a positive and significant effect on
Corporate Social Responsibility (CSR), while environmental costs, and company
size have no effect and are not significant on Corporate Social Responsibility
(CSR). The results of the second regression equation test showed that
environmental performance, environmental costs, company size, and Corportae
Social Responsibility (CSR) had no effect and no significance on financial
performance. Sobel test shows that the effect of environmental performance,
environmental costs, and company size on financial performance cannot be
mediated with Corporate Social Responsibility (CSR)
