在存在研发溢出效应的情况下，我们比较了私营和混合双寡头市场中排放税和绿色研发补贴之间的环境法规。我们表明，当绿色研发成本低（高）时，无论研发溢出如何，绿色研发补贴都比排放税更好（更差），而上市公司的存在鼓励政府采取补贴政策。然后我们表明，最优政策选择取决于研发成本水平和研发溢出程度。特别是，当研发成本较高且溢出率较弱时，政府应该选择征收排污税而不是对上市公司进行私有化。然而，当研发成本较低时，无论研发溢出如何，这种私有化政策都不为社会所接受。
In the presence of R&D spillovers, we compare environmental regulations between emission taxes and green R&D subsidies in private and mixed duopoly markets. We show that the green R&D subsidy is better (worse) than the emission tax when the green R&D cost is low (high) irrespective of the R&D spillovers, whereas the existence of a public firm encourages the government to adopt the subsidy policy. We then show that the optimal policy choice depends on the level of the R&D cost and the degree of R&D spillovers. In particular, when the R&D cost is high and the spillover rate is (not) weak, the government should choose the emission tax and (not) privatize the public firm. However, when the R&D cost is low, such a privatization policy is not desirable to society irrespective of the R&D spillovers.
