Influencing factors of agricultural carbon emission in Liaoning Province based on LMDI model
Under guidance of 14th Five-Year Plan,Liaoning Province accelerates modernisation of agriculture and rural areas,and pro-motes leap from a large agricultural province to a strong agricultural province,so it is necessary to clarify factors affecting agricultural carbon emissions in Liaoning Province,and to find out focuses of agricultural emission reduction.Based on historical data of agricultur-al carbon emissions in Liaoning Province from 2012 to 2021,main drivers of agricultural carbon emissions were identified through LM-DI factor decomposition method,and quantitative relationship of each variable was quantitatively analyzed using STIRPAT model.Through LMDI factor decomposition method,agricultural carbon emission in Liaoning Province was decomposed into agricul-tural carbon emission coefficient,energy intensity,agricultural industry structure,agricultural economic development level,and popu-lation size,in which agricultural carbon emission coefficient,energy intensity,and population size had a negative impact on agricultur-al carbon emission,while agricultural industry structure and agricultural economic development level had a positive impact.STIRPAT model showed that when other factors remain unchanged,agricultural carbon emission coefficient,energy intensity,agricultural in-dustry structure,agricultural economic development level,and population size changed by 1%respectively,agricultural carbon emis-sions changed by 0.499 7%,0.014 0%,-0.073 5%,-0.0241%,and 0.241 8%respectively,and model analysis presented with the LMDI factor decomposition the same results.In the context of the"Carbon Peak and Carbon Neutral"target,it was recommended to control application of chemical fertilisers,improve living environment of rural population,stabilise and maintain sustainable growth of rural economy,and promote effective carbon emission reduction in agriculture of Liaoning Province.
