中文摘要:

      利用中国减污降碳的主要市场型环境规制政策试点——排污权交易政策和碳排放权交易政策作为准自然实验，本研究基于2003—2018年中国268个地级市的面板数据，运用三重差分模型、空间杜宾模型及嵌套模型，探究减污降碳的政策协同与区域协同效应。研究发现：实施“双权”交易可以对碳排放和PM_2.5减排产生政策协同效应，并促进区域间的协同效应；实施单一的环境规制会对非排放清单的排放物减排产生负面效果，且没有形成区域协同效应；实施“双权”交易可以提高地区绿色全要素生产率，并促进区域间的协同效应。本研究的发现可以为中国推进减污降碳协同效应提供政策启示。

英文摘要:

      This paper used the main market-based environmental regulation policies of China’s pollution and carbon reduction - emission trading policy and carbon emission trading policy - as a quasi-natural experiment, based on the panel data of 268 prefecturelevel cities in China from 2003 to 2018, using triple difference model, spatial Dubin model and nested model, explored the policy synergy and regional synergy effect of reducing pollution and carbon emissions. The study found that the implementation of the “dual rights” transaction could produce policy synergy on carbon emissions and PM_2.5 emissions reduction, and promote inter-regional synergy. The implementation of a single environmental regulation had a negative effect on the emission reduction of non-emission list emissions, and there was no regional synergy. The implementation of “dual rights” transaction could improve the regional green total factor productivity and promote the synergy between regions. The findings of this study might provide policy implications for China to promote the synergistic effect of reducing pollution and carbon emissions.
