Research on Spatio-Temporal Evolution and Enhancement Path of Agricultural Carbon Total Factor Productivity in China from the perspective of Technological Heterogeneity
[Objective]Improving the agricultural carbon total factor productivity(CTFP)is of great sig-nificance to realize the carbon peaking and carbon neutrality goals.[Method]Based on the panel data of 30 provinces(cities and districts)in China from 2005 to 2022,this paper measured provincial agricul-tural carbon sinks,constructed the DDF-MGML productivity index model to measure China's agricul-tural CTFP,and explored its spatial-temporal evolutionary characteristics and enhancement paths.[Result]① China's agricultural CTFP grew at an average annual rate of 1.69%,and agricultural low-carbon technological progress was the main driver of its growth,while the low-carbon technology gap ra-tio and technological efficiency had limited contributions.② The spatial imbalance of China's agricul-tural CTFP growth was remarkable,showing a decreasing spatial pattern of"east-central-west".③ The growth path of China's agricultural CTFP could be divided into the catch-up effect,the technological in-novation effect and the technology leader effect.[Conclusion]In order to promote the growth of China's agricultural CTFP,we should minimize the technological gap between regions,develop enhancement dif-ferent strategies and strengthen interregional exchanges and cooperation.
