当前,围绕节能减排的补贴政策已广泛被各国政府采用,而不同的补贴政策可能在减排效果、产品产量及价格影响上存在差异。有鉴于此,本文在博弈的视角下,重点研究了价格补贴与研发补贴的污染减排效果差异。结果表明:政府的价格补贴在降低本国最终产品产量的同时增加了外国最终产品的产量,从而能够有效降低本国的污染排放,但将导致外国的污染排放出现较小幅度的增加,而研发补贴则将同等降低本国和外国的污染排放量。相比较而言,本国价格补贴比研发补贴对减少本国污染排放量的作用更为有效。此外,本文还发现了最优补贴水平受到污染税率等因素影响的事实。 Currently, subsidies around energy conservation and emission reduction have been widely adopted by governments, and different subsidies may have differences in emission reduction effect, product output and price impact. In view of this, this paper focuses on the differences in the effects of price subsidies and R & D subsidies on pollution reduction from the perspective of gaming. The result shows that the price subsidy of the government increases the output of the final product of foreign countries while reducing the output of the final product in the country, which can effectively reduce the pollution discharge in the country, but it will lead to the lesser increase of the foreign pollution discharge, while the R & D subsidy Will reduce the pollution emissions of their own countries and foreign countries equally. In contrast, domestic price subsidies are more effective than R & D subsidies in reducing domestic emissions. In addition, this paper also found the fact that the optimal level of subsidy is affected by such factors as the tax rate of pollution and so on.
