Abstract:

Agricultural modernization is a transition process from traditional agriculture to modarn agriculture, and the low-carbon agricultural way is an important approach in this transition. This study decomposes the CO2 emission into five contributory factors based on an expanded Kaya identity. The five factors are general technology, agricultural low-carbon technology, rural affluence, indirect urbanization, and total population scale. With the incremental analysis we find that the rural affluence, urbanization, and total population scale are driving the agricultural CO2 emission positively, while the general technology and agricultural low-carbon technology are driving the agricultural CO2 emission negatively. Contribution without direction to total agricultural CO2 emission caused by alteration of each factor is exhibited as: rural affluence influence > agricultural low-carbon technology influence > indrect urbanization influence > general technology influence > total population scale influence.

Key words: agricultural CO2 emission, Kaya identity, driving factor, factor decomposition
