What the study found
The carbon emissions trading system generally improved people’s well-being in the 273 Chinese cities studied. The study also found that the main pathway was the stimulation of green technology innovation.
Why the authors say this matters
The authors conclude that the carbon emissions trading system has a positive association with people’s well-being, and they suggest this is connected to green technology innovation. They also report that the effect varies by fiscal and market conditions, as well as by region and resource endowment.
What the researchers tested
The researchers used panel data from 273 prefecture-level cities in China from 2008 to 2020. They measured people’s well-being with an Entropy Weight Method-Technique for Order Performance by Similarity to Ideal Solution (EWM-TOPSIS) model and evaluated the carbon emissions trading system using a staggered Difference-in-Differences (DID) model.
What worked and what didn't
The findings indicate that the carbon emissions trading system generally improved well-being. Mechanism analysis suggests that green technology innovation was the main channel, while fiscal expenditure decentralization negatively moderated the effect and marketization degree did not show a moderating effect. The system had heterogeneous impacts: it improved well-being in non-Yangtze River Economic Belt regions and in non-resource-based cities, but it dampened well-being in Yangtze River Economic Belt cities and was statistically insignificant in resource-based cities.
What to keep in mind
The abstract does not describe limitations beyond the reported heterogeneity and threshold effects. The study’s scope is limited to 273 prefecture-level Chinese cities from 2008 to 2020.
Key points
- The carbon emissions trading system generally improved people’s well-being across 273 Chinese cities.
- Green technology innovation was identified as the main channel linking the policy to well-being.
- Fiscal expenditure decentralization weakened the policy’s well-being effect, while marketization degree did not moderate it.
- The policy’s impact varied by region: it helped in non-Yangtze River Economic Belt regions but dampened well-being in Yangtze River Economic Belt cities.
- The policy was positive in non-resource-based cities and statistically insignificant in resource-based cities.
