【摘要】：本文将企业的"排污—减排"决策引入基于拟线性需求系统的异质性企业垄断竞争模型,以研究贸易自由化对企业以及总体污染排放的影响。研究发现:在固定排污税率下,贸易自由化会增加全球总产出,但可能降低全球总污染排放,从而引致经济效益与环境效益的"双赢"。然而本文也发现这种情况只在初始排污税率较低之时成立。此外,在内生化的排污税率下,本文发现在一定参数下,最优的排污税率在贸易自由化以后应该上升。
[Abstract]:In this paper, the "emissions reduction" decision of enterprises is introduced into the heterogeneous enterprise monopoly competition model based on quasilinear demand system, in order to study the impact of trade liberalization on enterprises and overall pollution emissions. Trade liberalization will increase global total output, but may reduce global total pollution emissions, thus leading to "win-win" economic and environmental benefits. However, it is also found in this paper that this is true only when the initial emission tax rate is low. It is found that under certain parameters, the optimal emission tax rate should be increased after trade liberalization.
