Data Brief: Digitalization and Agricultural Carbon Decoupling data set

This dataset supports the empirical analysis in the manuscript titled "Can Digitalization Promote Agricultural Carbon Decoupling? Mechanism Identification and Heterogeneity Analysis Based on the KHB-feologit Framework," submitted to the Journal of Environmental Management. The dataset comprises a balanced provincial panel covering 31 Chinese provinces (autonomous regions and municipalities) over the period 2014–2023, yielding 310 province-year observations. The primary objective is to examine how digital-intelligence integration (digitalization) affects agricultural carbon decoupling status, as measured by a Tapio-framework-derived ordered decoupling index.
