Finally, the selected measurement criteria as the most effective criteria for measuring research variables were developed in the form of hypotheses to be examined based on regression analysis in the period 2015-2019 based on the creation of 355 year-company observations. Results in the qualitative part of the approval of 6 criteria for measuring the corporate governance system; There are 6 criteria for measuring managerial conservatism, 6 criteria for measuring competitiveness, and 6 criteria for measuring voluntary disclosure.
