Abstract
With the change of social economic system and the rapid growth of agricultural economy in China, the amount of agricultural energy consumption and carbon dioxide emissions has increased dramatically. Based on the estimation of agricultural carbon dioxide emissions from 1991 to 2018 in China, this paper uses EKC model to analyze economic growth and agricultural carbon dioxide emissions. The Kaya method is used to decompose the factors affecting agricultural carbon dioxide emissions. The experimental results show that there is a co-integration relationship between economic growth and the total intensity of agricultural carbon emissions, and between economic growth and the intensity of carbon emissions caused by five types of carbon sources: fertilizer, pesticide, agricultural film, agricultural diesel oil and tillage. Economic growth is the main driving factor of agricultural carbon dioxide emissions. In addition, technological progress has a strong role in promoting carbon emission reduction, but it has a certain randomness. However, the impact of energy consumption structure and population size on carbon emissions is not obvious.

Global warming is an indisputable fact, which has seriously affected the survival environment and development of human beings
The results showed that China’s carbon emissions decreased by 2466 million tons theoretically from 1957 to 2000, of which 95% was due to the decrease of energy intensity, only 1.6% and 3.2% were due to the adjustment of fossil energy structure and the utilization of renewable energy
This paper studies the impact of socio-economic system changes on agricultural carbon dioxide emission reduction from the perspective of environmental protection
Summary
Global warming is an indisputable fact, which has seriously affected the survival environment and development of human beings. In the past 30 years, China’s economy has developed rapidly, and energy consumption has increased rapidly, which directly leads to a sharp increase in agricultural carbon dioxide emissions. 2.1 Environmental protection and development of socio-economic system. 2.1.1 Market economy, economic development and environmental protection. The impact of socio-economic institutional change on agricultural carbon reduction progress, efficiency improvement, and no great social development [11]. Eco-environment and economic development are closely linked, and environment has the dual nature of promoting and restricting economic development. Eco-economics or environmental economics is the subject of studying the ecology of economic development mode. We should reshape eco-economics or environmental economics according to the orientation of ecology of economic development mode
