Abstract: Research on inter-provincial correlation of agricultural carbon emissions could lay foundation for the regional synergies, and benefit the realization of dual goals of green agriculture development and carbon emission reduction. According to the basic framework of the national greenhouse gas emissions inventory guidelines, agricultural carbon emissions were measured comprehensively in five sectors, namely, agricultural energy, farmland use, ruminant feeding, crop planting and agricultural waste. Regional correlation of carbon emissions were verified by spatial statistical analysis, and the possible reasons were explored from the perspectives of spatial adjacency, economic dependence and technological association by nonparametric QAP regression. Finally, countermeasures were proposed including optimizing energy layout, improving energy efficiency; focusing on the diffusion effect of emission reduction technologies; formulating differentiated emission reduction measures by sub-region and sub-sector; establishing “four principles, three cores” regional synergistic emission reduction mechanism.

Key words: inter-provincial correlation, spatial statistics, nonparametric regression, synergistic emission reduction
