Analysis Of Regional Difference And Affecting Factors Of China’s Agricultural Carbon Emission Level

The current study on agricultural carbon emission indicates that agriculture has turned tobe one of the main sources of greenhouse gas emissions. Low carbonization of agriculture hasalready caused the extensive consensus in the international scope. In recent years, the worldagricultural has entered into a stage of low-carbon agricultural economy, which in China isstill at the starting stage. Therefore change from high carbon to low carbon agriculturebecomes a material issue in China. In this context, it has certain practical significance to studythe problems of Chinese agricultural carbon emission. Because of vast territory, significantregional difference exists in many aspects such as natural conditions, economic developmentand population characteristics. Agricultural development and agricultural carbon emissioncondition closely related to these factors may also have regional differences. Therefore thispaper, from the perspective of regional differences, researches on problems of agriculturalcarbon emission, and analyzes its influencing factors.The paper, based on7carbon sources including chemical fertilizers, pesticides,agricultural films, nitrogen fertilizer application, agricultural machinery, irrigation andburning crop residue in agriculture production, calculates the carbon emissions in China overthe period1995-2011. Then the carbon emissions in four areas (the eastern, central, west andnortheast area) are calculated respectively and the characteristics of agricultural carbonemission in each area are analyzed. This paper, based on the method of the Theil index,quantifies the regional differences of agricultural carbon emission in China, and respectivelymeasures the Theil index of both carbon emission intensity and per capital carbon emission,and the calculation results are compared. Furthermore, using Kaya identity, this paperconducts an empirical analysis of influencing factors of per capita agriculture carbon emissionbased on data in30provinces from1990-2011.The research results show: both total agricultural carbon emission and per capitaagricultural carbon emission are in growth, and the growth begins to slowdown in recent years,the agricultural carbon emission intensity decreased year by year; burning crop residue turnsto be the primary carbon source, and the second is fertilizer; in17years total agriculturalcarbon emission in China experienced three stages "growth--slow drop--new growth". Thetotal agricultural carbon emission in the eastern region is the highest, the carbon emissionsintensity and per capita emissions in the northeast region is the highest; there exists regionaldifferences in the emission structure; there are significant regional differences in agriculturalcarbon emission measured by both the two targets, and regional differences in per capitalcarbon emission are more obvious than carbon emission intensity. The contribution ofinter-regional and regional differences to the overall differences is nearly the same for carbonemission intensity.Influencing factors analysis show: in the national level, rural economic level representedby per capita total output value is the main influencing factor, and its elasticity is1.295;Moreover, there is a significant inverse U relationship between them, and the inflection pointis13357RMB. Emission intensity and agricultural structure has significant effect on per capita carbon emission, and the elasticity is respectively0.114,0.522. the affecting degree ofeach factor varies from one region to another.Finally, according to the above results, policy recommendations from4aspects,including the development of agriculture, improvement of production efficiency, adjustmentof the structure, coordination of regional development, in terms of agricultural carbonemission reduction in China are put forward.
