Abstract

The economy of China is growing rapidly. With this overwhelming growth, the country is experiencing a higher level of carbon emissions. Amid this backdrop, China is under immense pressure to reduce carbon emissions up to a sustainable level. This study adapted 31 provincial panel data from 2007 to 2017 using factor analysis system SBM-undesirable model to calculate the agro-ecological output of each province respectively and used a carbon transfer network impact analysis panel to calculate ecological performance impacts. Results show that (1) overall agro-ecological efficiency in China shows an upward trend but regional differences are evident. The efficiency in the eastern region is higher than that in the central and western regions but the extent of informatization in the central region is higher than that in the western region. (2) Informatization will significantly promote agro-ecological efficiency. (3) Changes in agricultural planting structure, agricultural value-added per capita, employment of human capital in the agricultural sector, and agricultural scale management are also important factors affecting agro-ecological growth. (4) China's amount of carbon transfer is growing year by year, and energy-intensive areas and heavy industry bases are undertaking carbon transfer from the eastern coastal regions; (5) Jiangsu, Henan, and Hebei (Hubei) have the highest centers between 2007 and 2012; (6) inter-provincial carbon transmission is concentrated mainly in the metal smelting and rolling processing industries as well as in the coal, heat, and supply industries.

Keywords: Agro-ecological efficiency; Carbon emissions from agriculture; Informatization; Pollution from agricultural non-point sources.
