[Coupling and Coordination of Agricultural Digitalization and Green， Low-carbon Development in China and Obstacle Factors Analysis].

The digitalization and green and low-carbon development of agriculture are two important directions for the high-quality development of China's agriculture and rural areas and rural revitalization， and they are also important ways to achieve the "dual carbon" goal. Based on the entropy weight method， the coupling coordination degree model， the Dagum Gini coefficient， the kernel density estimation， and the obstacle degree model， the spatiotemporal evolution characteristics and obstacle factors of the coupling coordination degree of agricultural digitalization and green and low-carbon development in 31 provinces of China from 2011 to 2022 were explored. The results show that： ① The average growth rate of China's agricultural digitalization level was 5.49%， and the development level of the main grain sales area was the highest. The average growth rate of green and low-carbon development level of agriculture was 1.83%， and the development level of the main grain sales areas was relatively high. ② The coupling and coordination degree of agricultural digitalization and green and low-carbon development was low， but it showed an upward trend year by year， with the average value increasing from 0.312 in 2011 to 0.427 in 2022. The development differences between regions were the main reasons for the differences in the coordinated development of agriculture， but the differences showed a decreasing trend. ③ Rural electricity consumption and regional post and telecommunications services were the two factors with the greatest obstacle degree in agricultural digitalization， and the average obstacle degree in the four years was 23.36% and 21.11%， respectively. The water-saving irrigation rate was the greatest obstacle factor in the green and low-carbon development of agriculture， and the average obstacle degree was 29.23%. Therefore， it is necessary to accelerate the construction of agricultural digital infrastructure， introduce technologies to improve resource utilization， establish a cross-regional coordinated development mechanism， and promote the coordinated development of agriculture.
