“…Additionally, with subsidies for delayed fertilization control, soil testing and formula fertilization, and R&D of energy-saving and environmental protection machinery technology, agricultural carbon emissions could be reduced, as well as the adjacent regions due to technology spillovers [22]. On the other hand, financial support for agriculture could promote competition in agricultural development industries between local and adjacent regions, which would increase agricultural carbon emission and inhibit agricultural green development by a high input of energy, fertilizers, pesticides, untreated agricultural wastewater containing nitrogen and phosphorus and other agricultural materials [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. Furthermore, one region would gather more agricultural production resources which may have a siphoning effect on the adjacent regions, suppressing the adjacent regions' level of agricultural green development [23].…”
