Abstract
Establishing a coordinated governance mechanism for regional carbon emissions is an essential way to achieve carbon peak and carbon neutrality, while the study of interprovincial carbon emissions transfer is one of the important foundations of regional carbon emissions coordinated governance research. Based on the multiregional input-output (MRIO) model, this study calculated the carbon emissions from both the producers' perspective and the consumers' perspective and analyzed the interprovincial net carbon emissions transfer decision. Furthermore, the logarithmic mean Divisia index (LMDI) method was adopted to decompose the factors that affect the province's net carbon emissions into technological effect, structural effect, input-output effect, and scale effect. It was revealed that the input-output effect was the primary influencing factor of the net carbon transfer at the provincial level.

IntroductionChina’s economy has grown massively since the 21st century. As of 2020, China has achieved its first centenary goal—building a moderately prosperous society in all respects and is striding forward to its second centenary goal
We aimed to provide a basis for the construction of a coordinated governance mechanism for regional carbon emissions and emissions reduction plans to promote the achievement of carbon peak and carbon neutrality
In 2012, 2015, and 2017, the highest total carbon emissions from the consumers’ perspective were coastal provinces with large populations and high consumption levels, such as Shandong (566 million tons per year) and Guangdong (528 million tons per year). e lower ones were in regions with relatively small populations and low consumption levels including Tibet (15 million tons per year) and Qinghai (41 million tons per year). e primary reason is the large differences in the total population and consumption levels between regions
Summary
China’s economy has grown massively since the 21st century. As of 2020, China has achieved its first centenary goal—building a moderately prosperous society in all respects and is striding forward to its second centenary goal. If the inter-regional transfer of carbon emissions is ignored during the promotion of carbon emissions reduction, on the one hand, it may cause some regions to import high-carbon products from other regions for carbon emissions reduction. It will impair the effectiveness of emissions reduction policy, and even cause partial decrease with overall increase [1, 2]. Before planning how to scientifically promote the fair distribution of CO2 reduction between regions, we need to pay attention to the following two issues. How is the regional distribution of carbon emissions transfer in China? What are the main factors affecting the transfer of carbon emissions between regions in China? How is the regional distribution of carbon emissions transfer in China? Second, what are the main factors affecting the transfer of carbon emissions between regions in China? erefore, this study is committed to carrying out the analysis of interprovincial carbon emission transfer, characterizing the relationship of carbon emission transfer, discussing its influencing factors, and consolidating the foundation for the research on carbon emission collaborative governance
