Privatisation policy with different oligopolistic competition in the public utilities market

This study constructs an oligopoly model in public utilities sector to explore the optimal privatisation policy and factors affecting equilibrium outcomes explores proportion of state-owned shares. We also offer empirical evidence China’s from 1985 2019 prove applicability results. The results show that, depending on product differentiation, cost variance, technical level, nationalisation, partial or full can be optimal. Improving capital efficiency increases social welfare Model PP, but not PS. Product differentiation improves at expense profits SS model. In PM, improvements boost private enterprise induce a decrement welfare. A high shares fail improve SM. word, value range parameters competition modes affect market players’ distribution, which identifies with analysis development.
