The Combined data method has been used to test the research hypotheses. The Herfindahl–Hirschman, the Lerner, and the Industry-adjusted Lerner Index measure product market power. To measure the company's market value, Maditinos et al. (۲۰۱۱) were used to measure capital expenditures. The model presented in Liao, Lin and Lin, (۲۰۱۶) has been used, and the Pulic Model (۲۰۰۴) to measure value creation. The results show a positive (negative) correlation between the market value of the company and the Herfindahl–Hirschman Index and Lerner Index (Industry-adjusted Lerner Index). There is a positive (negative) correlation between capital expenditure and the Herfindahl–Hirschman index and Lerner Index (Industry-adjusted Lerner Index).
