摘要
在“双碳”目标的时代背景下,中部六省不仅面临经济开放瓶颈,还承担着巨大的节能减排压力。我国当前的发展需要兼顾经济开放与减污降碳的双重需求,本文特别关注了经济开放度对碳排放的影响。在环境库兹涅茨曲线的理论基础上,通过构建省级经济开放度指标体系和估算2000—2019年中部六省二氧化碳排放量,运用动态面板GMM模型,借助差分广义矩方法对实证模型进行了估计。研究发现:首先,对内开放对于中部六省的经济开放具有正向贡献并起主要作用;其次,当处于低发展水平时,经济开放对碳排放产生负向影响,当进入到高发展水平时,经济开放对碳排放产生正向影响,且该影响强度相较于低发展水平要小;最后,随着经济发展水平的提高,经济开放对碳排放的影响强度呈反向变化趋势。中部六省处理好经济开放与碳排放的关系是实现“双碳”目标的重要保障。基于以上研究结论,提出政策建议:中部六省需要壮大消费市场,扩大对内开放;在权衡高碳排放风险的前提下,适当提高经济开放水平;统筹兼顾经济开放与减污降碳,加快产业结构转型升级。
Under the background of the“dual carbon”goal,the six central provinces are not only facing the bottleneck of economic opening,but also bear the huge pressure of energy conservation and emission reduction.China’s current development needs to take into account the dual needs of economic openness and pollution reduction and carbon reduction,so this paper pays special attention to the impact of economic openness on carbon emissions.Based on the theoretical basis of the environmental Kuznets curve,by constructing a provincial economic openness index system and estimating the carbon dioxide emissions of the six central provinces from 2000 to 2019,using the dynamic panel GMM model,the empirical model is carried out by means of the difference generalized moment method estimate.The study found that:first,opening to the domestic market has a positive contribution and played a major role in the economic opening of the six central provinces;second,when it is at a low level of development,economic opening has a negative impact on carbon emissions,and when it enters a high level of development,economic opening has a positive impact on carbon emissions,and the impact intensity is smaller than that of low development levels;finally,with the improvement of economic development level,the impact intensity of economic opening on carbon emissions shows a reverse trend.It can be seen that properly handling the relationship between economic opening and carbon emissions in the six central provinces is an important guarantee for achieving the“dual carbon”goal.Based on the above research conclusions,it is pointed out that the six central provinces need to expand the consumer market and expand their internal opening;on the premise of weighing the risk of high carbon emissions,the level of economic opening should be appropriately increased;the economic opening and pollution reduction and carbon reduction should be considered as a whole,and the industry should be accelerated.Policy recommendations such as structural transformation and upgrading.
